Product review: Pioneer TS-WX210A

If you’re keen about listening to music in the car, then the chances are your standard stereo setup will leave wanting more – whether it suffers from a muddy sound or lack of bass… or both!

While replacing the main speakers with better aftermarket alternatives can help with improving clarity, an increase in bass response can be more difficult to achieve – especially taking into account road and engine noise.

Of course, usual subwoofer box solutions will happily remedy this malady – but do so at the expense of eating up valuable boot space.

Thankfully another solution exists in the form of ultra compact subwoofer designs; known as stealth, hide-away, or underseat subwoofers.


Depending on the car in which it will be used, installation is within the scope of the DIYer, although many motorists will choose to get the unit professionally fitted, as a power lead has to be run to the battery or main fuse box. The unit takes a signal feed from either the speaker wires (high level) or a low level input, via an RCA lead out of your radio/head unit, meaning the Pioneer is compatible with both standard manufacturer and aftermarket car stereo systems.

This compact pioneer can be installed out of sight in a variety of locations in the vehicle – such as under the front passenger seat. If wired correctly the sub will automatically power-up when you switch on your stereo and depending on what functionality your headunit has, you’ll be able to adjust the subwoofer level from that. Aftermarket units usually have this provision, but this isn’t always the case with standard manufacturer systems. Either way, the Pioneer comes with a wired remote control that gives you easily accessible adjustment of both the unit’s gain (output level), phase and tuning of the frequency response (50-125 Hz, -12dB/oct.)

In use:

This stealth subwoofer effectively reinforces classic and acoustic music, but can sound a bit thumpy on some rock and pop if the frequency response is dialed up past 75Hz – especially apparent if the gain level is cranked up as well.

However, in most instances, I found it possible to dial in the right amount of bass to suit most music. Dire Straits ‘Money for Nothing’ really motored along with considerably more gusto than running off door speakers alone, as did Paul Simon’s ‘Graceland’. The same was true of acoustic and jazz music, with all the respective instruments having considerably more weight and authority than they did sans sub.

What the manufacturer says:

“Compact SPL power, the Pioneer TS-WX210A focuses on functionality and performance. Use this 20cm (8″) sub vertically or horizontally: it takes up a minimum amount of space in the boot or virtually disappears under a seat. But its performance punch is an attention-grabber.”


Writeonmotoring Verdict:

Although it offers more in the way of bass reinforcement, rather than low-bass extension, this compact Pioneer underseat sub can help to flesh out a weedy sounding stereo and is easy to use.
