Best Rockford Fosgate Subwoofers Reviewed
Are you ready for the in-depth reviews? Because I can't want to show you what these subwoofers are all about!
The Punch P3 series is what launched Rockford Fosgate into the top-tier portion of the car audio equipment industry. It's what made the brand what it is today.
As the flagship model of the P3 series, all eyes – well, ears – are on the P3D4-12.
And it handles the pressure with unmatched grace, meeting – and then surpassing – all of my expectations:
The P3D4-12 Punch P3 may be the ultimate subwoofer that Rockford Fosgate has to offer, period. If you want to hear – and feel – every beat, this is the subwoofer to get.
What's so interesting about this subwoofer is that there's nothing particularly interesting about it – it's the practical, well-thought-out, high-quality design that makes it outstanding.
The solid aluminum cone employs VAST technology – a vertically mounted surround – for a 25-percent performance boost, and features a FlexFit design for the basket, allowing you to adjust the angle of the subwoofer once it's mounted.
The dual 4-Ohm voice coil is already an advantage in itself, considering the freedom that you get when hooking it up to your system. The anodized aluminum voice coil former is temperature-resistant by design, but it's when you add the venting into the mix that the subwoofer's heat dissipation system shines:
The P3D4-12 won't overheat, no matter how hard you push it.
Once you have it hooked up, it becomes clear just how loud this subwoofer can go. It brings serious volume levels to the table – and quite effortlessly, too. You won't hear it struggle; even as the volume goes up, the sound clarity remains unchanged.
With 600 watts of continuous power – and a peak rating of 1200 watts – this shouldn't come as a shock, even with the 85-dB sensitivity.
I was initially worried about the frequency range being limited to 28 to 250 Hz, but this subwoofer doesn't seem to care at all. It offers powerful and versatile performance, pumping out rich and clean bass that you can hear and feel.
It's insane how much air this thing moves – and with reliability that's rarely seen in its price range, too!
If you're trying to fit your upcoming car audio upgrades into a tight budget, then you'll be happy to know that this next option – the P1 10-inch sub – costs half as much as my top pick.
A member of the world-famous Punch family of subwoofers and designed to deliver quality sound on a budget, it's a perfect choice for the performance-oriented crowds that aren't ready to splurge on a high-end subwoofer yet.
And if the pocket-friendly price tag alone isn't enough to put a smile on your face, the rest of this review certainly will!
I'm a big fan of the subwoofer's traditional looks and compact dimensions:
Considering that it requires a cutout of 9.13 inches, and a depth of 5.33 inches for mounting – whether in a sealed or vented enclosure – its size is more than manageable.
It packs all the features that the Punch family is known for, including the Kevlar fiber reinforced paper cone supported by the high-density poly-foam surround. The spider venting integrated into the StampCast basket is another critical feature here, as it helps keep the temperature under control.
Plus, it incorporates the VAST technology, increasing the cone area by up to 25 percent. As a result, the P1S4-10 can push more air than a regular, same-sized driver.
Now, as far as power handling goes, this one is a bit of a step-down compared to the 12-inch subwoofer that I talked about earlier. It's rated at 250 watts RMS, which doesn't sound overly impressive for a 10-inch woofer – especially not when you add the not-so-stellar 85-dB sensitivity.
Still, if you want clean, accurate bass, this one's more than happy to deliver the thump without becoming too distracting. As much as we all love ground-shaking bass, sometimes a good-sounding low end – even without too much power – is all you need.
The frequency response range of 30 to 250 Hz proves that the P1S4-10 doesn't fall behind my top pick by a lot. The accurate response and sound quality are there – albeit with slightly less power.
The most significant advantage of a powered subwoofer enclosure is that you can upgrade the sound of your system – factory or after-market – without going through the stress of finding the right components.
Rockford Fosgate did all the work for you, combining a 12-inch driver, an amplifier, and a custom-fit enclosure into one perfectly harmonious and hard-hitting unit that is the P300-12.
All you have to do is wire it up – and enjoy the bass!
When I got my hands on one of these, I couldn't help but feel surprised by how solid and well-made it is. I mean, sure, I tested enough of their products in the past to learn to expect certain levels of quality from them, but boy, do they still manage to surprise me sometimes.
Even more so, it's simple, but in an attractive way that isn't overly distracting, and shows that the focus was on the performance. I wouldn't dare to call this one compact or light, though – not when it measures 15 x 19.8 x 11 inches – so be sure to check whether you have the room for it in your car.
Still, the sturdiness of the high-density, 5/8-inch MDF cabinet makes up for the increase in size and weight, and sets the stage for its powerful performance!
Its bass performance is equally as tight and precise as the enclosure itself. You can look forward to a powerful punch that isn't accompanied by the rattling of a poorly constructed cabinet.
And on that note, yes, the P300-12 puts on a stellar performance – the closed-loop design makes sure that it does.
The built-in amplifier has an RMS rating of 300 watts, enough to match the requirements of the 12-inch driver and the sealed enclosure. Punchy, loud, and incredibly accurate performance is a given. Even more so, with the onboard EQ, you get the option to tweak the audio output to your liking.
The 35 – 150 Hz frequency response range is somewhat disappointing, though. It's a bit of out of character for a 12-inch sub to bottom out at 35 Hz.
If all you want is bass – and lots of it – the P3-2X12 Punch Dual P3 is, by far, your best bet.
Granted, this isn't a subwoofer for someone sticking to a tight budget. But the sound output and clarity of this P3 duo are so exceptional that, even if it's too expensive for you at the moment, it's worth saving up some cash and getting it in the future.
If you're prepared to whip out your credit card straight away, though, know that this beast of a loaded enclosure will take your system's sound quality and volume to a whole new level!
The P3-2X12 comes loaded with two top-of-the-line Punch P3 subwoofers, so you already know what to expect from the drivers:
Following the signature design of the P3 line, each of the 12-inch drivers' sports a 25-percent larger cone surface thanks to VAST tech, as well as vented design and high-temp voice coil to help fight the heat.
And the enclosure doesn't fall behind build-quality-wise, either. It's made out of 5/8-inch thick MDF – a durable and versatile material – and topped off with a heavy-duty carpet for a slip- and scratch-resistant finish.
The whole thing measures 15.1 x 33.9 x 15.7 inches and weighs a staggering 89 pounds. So, the weight is something to consider, especially if you plan on installing this monster by yourself.
If there's one way to describe the P3-2X12, the phrase "bass-pumping beast" would be fit. I mean, the power ratings alone are insane:
Between the two of them, these Punch P3 subwoofers pack 1200 watts RMS, with their peak power rating clocking in at 2400 watts!
Its frequency response range of 27 to 250 Hz is pretty similar to the P3D4-12 Punch P3, but it's capable of handling two times as much power. And to add to it, it features the brand's proprietary low-noise, high-flow port.
The resulting sound, as you can imagine, is brilliant. There's no static or stuttering – only deep, rich, highly accurate low-end pushed out at insane volumes. It's enough to impress even the most hard-core audiophiles among you.
Whether you're concerned about budget limitations or lack of available space – or want to add more bass to your system without too much hassle – this shallow-mount, loaded subwoofer enclosure may be the answer.
So, I suggest that you stick around and check out this R2S-1X10 in-car subwoofer system that can add powerful bass to your vehicle without taking up too much precious space – or burning a hole in your pocket!
Rockford Fosgate knows its target audience and does its best to meet their needs, keeping everything as straightforward as possible.
First, there's a relatively small footprint. The R2S-1X10 measures 13.5 x 19.0 x 5.25 inches, meaning that it only needs about 5 inches of depth for mounting. The wedge design makes it perfect for cars with minimal space.
And second, it's insanely rugged, which leads me to believe that it's designed for harsh environments and work trucks, where it may have to withstand a lot of daily abuse:
Besides using thick, 5/8-inch MDF for cabinet construction, the enclosure is also wrapped in a heavy-duty carpet, which makes it resistant to slips and scratches – and gives it a more premium look, too.
And inside this sealed enclosure sits a single 10-inch Prime subwoofer that's in charge of delivering low-end sound to your car's audio system.
Well, it doesn't sound as tough as it looks, I can tell you that. It doesn't mean that it's not worth considering, though – it's all about what you're after:
If you want glass-shaking power and thundering bass, this probably isn't the subwoofer for you. But if you're after low-end clarity, the R2S-1X10 is more than enough.
You see, the subwoofer has a power handling of 200 watts RMS, with its peak power clocking in at 400 watts, which isn't mind-blowing or anything – but gets the job done. It has a decent hit to it and helps the low end come through with enough power and clarity.
On that note, the frequency response range is somewhat limited, going from 38 Hz to 250 Hz, but as I said, it rounds out the sound well.
A good portion of my round-up is focused on 10-inch and 12-inch woofers, but I get that not everyone's looking to add teeth-rattling, ear-crashing bass to their car's audio system – or has the space needed for that large of a subwoofer.
A carefully selected 8-inch driver can still pack a punch in its relatively compact frame, though. And if that's what you're after, you should give the P2D4-8 a chance.
This Punch series sub is an excellent choice for casual hobbyists and all those who want to get a bit more "boom" with minimal investments.
The P2D4-8 is smaller compared to what you've seen so far – and I'm not only talking about the actual driver size, either. This Punch woofer requires a mere 4.76 inches of depth for mounting and a cutout diameter of 7.13 inches.
It features a Kevlar fiber reinforced paper cone, coupled with high-density poly-foam surround, a StampCast basket, and stitched tinsel leads, amounting to a robust and reliable subwoofer.
Interestingly enough, the so-called FlexFit frame – hidden underneath the cast aluminum trim ring – allows slight adjustments once it's already mounted since it utilizes slots, rather than single screw-sized holes.
Besides, it performs equally well in sealed and vented enclosures; you're free to choose what works best with your system.
The design allows plenty of room for heavy excursion, reduced fatigue, and an overall sound performance boost. But with an 8-inch driver and 250 watts RMS, this isn't a sub that will shatter all the windows of your car.
While its power handling capabilities may leave it slightly underpowered and the frequencies don't go below 43 Hz, the driver still manages to pump out relatively clean-sounding bass, though.
Plus, you're looking at a P2 dual voice coils 4-Ohm sub here, which means that you can always hook up two or three of these to your amplifier – and you should seriously consider doing that:
Even though the sound quality is decent, the output volumes are less than stellar, partly due to the RMS rating – and partly because of the reduced 83-dB sensitivity.
I want to wrap things up with one of Rockford Fosgate's amplifiers because your audio system's sound quality and delivery are only as good as your amp.
Instead of pushing the power limits to the extremes, the focus with this class D amp, known as the R500X1D, was on finding a balance between performance and price – even if it means sticking to a comfortable wattage band.
Stick around for a detailed assessment of its features and performance, and find out whether it's the right amplifier for your car audio system!
The R500X1D is a clean-looking amplifier with an all-black finish and housing that measures 1.98 x 6.77 x 8.5 inches. It's slim enough to fit into small spaces, like under the seat of your car.
Its size may be small, but the robust and resilient body with cast aluminum heat sinks protects the inner components and adds to its overall durability. Even more so, it features protective mechanisms that prevent short circuits or overcurrent damage.
I like that the controls – as well as the connectors – are grouped on the stealth top-mounted control panel. On that note, the onboard EQ and the wired remote controls allow you to tweak the sound to your liking.
Advertised as the amplifier that will rock your world, this Prime Series mono amp can run a 2-Ohm load and drive a subwoofer with up to 500 watts RMS – or 300 watts at a 4-Ohm load. That should be powerful enough for their 10-inch and 12-inch woofer drivers.
These ratings are CEA-2006 compliant, so you're not looking at inflated marketing claims; these are the amp's real power handling specs. Add the comfortable frequency response range of 20 to 250 Hz, the high SNR ratings, and the option to optimize the audio quality, and you get a pretty solid unit.
One might argue that you're not getting audiophile-grade sound experience, but if you want bass on a budget, the R500X1D is one of your safest bets.
Best Rockford Fosgate Subwoofers – Frequently Asked Questions
Q: Is there a difference between a regular subwoofer and a car subwoofer?
A: While you can substitute a car subwoofer for a home subwoofer, and vice-versa – at least in theory – specific design differences between the two may hinder your results.
A regular or home subwoofer pumps out more air and is optimized to play at full volume in large areas, while a car subwoofer has a near-field design and works in enclosed spaces. Because of these efficiency differences, a car subwoofer generally requires much more power to get to the same decibel levels.
There's a drastic difference in impedance – or resistance – of these two types of subwoofers, too. A car subwoofer is designed to work with a car battery, which is why it typically has a 4-Ohm resistance rating, as opposed to a regular subwoofer, which is often rated at 8 Ohms.
Q: What is the best car subwoofer?
A: It's hard to tell what the right subwoofer may be for your car because the answer depends on so many different factors – and personal preference is one of them.
Some people prefer shallow-mounted designs, while others have the space for a large-and-in-charge subwoofer. Even more so, while some only need their subwoofer to be loud, others will prefer a balanced and precise low-end sound performance.
In short, you should probably sit down and make a list of "requirements" for your subwoofer before you make your pick.
That said, I do think that the P3D4-12 Punch P3 has a broad appeal in terms of both design and performance.
Q: Are Rockford Fosgate P3 subs good?
A: Are you kidding me? Punch subwoofers are designed for deep bass that packs a relentless punch – pun intended. The P3 subwoofers are the best-performing Punch line yet, and I'll even go as far as to say that it's the series that made this brand what it is today.
A quick look at any P3 subwoofer is enough to see why:
The VAST surround increases the cone surface area by up to 25 percent allowing more output, and the anodized aluminum cone and dust caps with integrated spider venting enhance motor cooling. The hybrid StampCast basket adds strength but minimizes weight and resonance, while the FlexFit basket makes it easy to mount.
I barely scratched the surface of what makes the P3 subwoofers the absolute best there – but you get the point!
