best 8 inch subwoofers - what to look for

When you think of subwoofers, the chances are that the tooth-rattling bass is the first thing that comes to your mind. 

And while I can’t help but agree with you on that one, here’s the thing: 

There’s a lot more to the best subwoofers than that my-head-is-going-to-explode feeling – especially when they come in a compact, eight-inch frame. 

And this next section is going to tell you all about it! 


You can’t get that boom you’re after without power. However, here’s where it gets tricky: 

There are two aspects you need to keep an eye on here to determine how powerful the best 8-inch subwoofer is. 

RMS Power 

The power rating that matters is the RMS – the amount of power a subwoofer can handle continuously

Be sure to match the RMS rating to the amplifier, though. Your amp should be able to pump out 75 to 150 percent of the subwoofer power rating. 

Peak Power 

The peak power rating doesn’t equal its maximum capacity. It does, but not in the way you think it does. 

Allow me to clarify: 

Peak power does affect the subwoofers overall performance but to a limited degree. It shows you the maximum voltage that the unit can handle – but only in short bursts, for a limited amount of time. 


Besides the actual power, sensitivity is probably the second most crucial factor you should consider when buying subwoofers. More sensitivity ensures better output and sound quality using the same amount of power. 

The sensitivity indicates how efficient the subwoofer will be regarding converting power into output volume

Frequency Range 

A subwoofer frequency range is an indicator of its frequency limits – how high or low it can go sound-wise. If you want to get that super deep, booming bass, make sure that you pick a unit with the lowest possible frequency limit. 

Some of the best subwoofers typically have a lower limit in the 20 to 30 Hz range

Enclosure Type 

The type of enclosure plays a significant role in the subwoofer’s overall performance – mainly the volume

  • Sealed enclosure – one that doesn’t have any openings – produces a more controlled, deeper sound, but sacrifices some of the volume to achieve it. 

  • Ported enclosure – one that has one or more openings to ensure free airflow – can put out very high volumes, but sacrifices some of the sound clarity. 

Number of Voice Coils 

I’d say that the single voice coil subwoofers are a suitable fit for anyone looking for a quick and affordable solution to upgrading their audio system. Plus, they don’t necessarily skimp on the actual quality of the bass. 

Dual voice coil subwoofers, on the other hand, are something real audiophiles will appreciate. If you want to customize your audio system to get the best possible sound quality, dual voice coils are the way to go. 


The actual dimensions and size of the subwoofer can be a somewhat limiting factor in your future purchase. It’s essential that you know how much space you have available – and which subwoofer will be able to fit into it. 

The four most popular subwoofer sizes are 8, 10, 12, and 15 inches in diameter. 

Our focus today is on the most compact ones – the best 8-inch subwoofers – but I figured you’d be interested in knowing what else is out there.  


Since your music travels through your stereo system as an electrical signal, the speaker wire brings a specific resistance – impedance – into the circuit. 

All speakers have an electronic component called the resistor, and it’s rated in ohms – a measurement that tells you about the level of resistance it provides. 

Your stereo will probably have either a 4-ohm or a 2-ohm rating, but it all comes down to what works with your given amplifier. Each amplifier is designed to perform with a specific impedance.
