Sony SA-W2500 Subwoofer: Review

My Sony SA-W2500. Overall I’ve been very pleased with my purchase. There are, for sure, better subs out there, but for the money I paid, this unit has delivered excellent value.

If you are planning to buy a subwoofer, then you clearly a more discerning audio listener than the average person.  I bought my Sony SA-W2500 subwoofer to give more low end and fill out the sound, when I realised that my Sony SS-B1000 5-1/4-Inch Bookshelf Speakers just weren’t delivering the amount of bass that I desired.

(They are excellent speakers for the price that I paid, but they are necessarily limited in size and output by being bookshelf speakers).

Rear view of my sub. Knobs control sound level and sensitivity. Power saving can be switched on or off. Input can come from jack or speaker cables.

The SA-W2500 Subwoofer delivered exactly what I wanted and more and has shown itself to be excellent value for money – there are better subwoofers out there, but nothing this great in this price range, and being an audiophile on a limited budget, believe me I searched!

Buying the Sony SA-W2500 has made a dramatic difference to our enjoyment of the TV and converted my wife from being a skeptic to a true believer in the power of bass (she complained when I first told her about my plans to buy a subwoofer).

Music also sounds fuller and has so much more depth when heard through the Sony subwoofer.  (I have a Sherwood RX-4105 100 Watt Stereo Receiver playing through my SA-W3000 subwoofer, as well as a pair of bookshelf speakers on another channel).

The Sony SA-W2500 features a 12 inch 180 Watt powered subwoofer.  The 6 Ohm mica-reinforced cellular woofer has a 20-200Hz frequency response.

You can adjust the volume level of the subwoofer at the back, and also the sensitivity of the unit using the frequency cut off point.

There are both line-level and speaker-level inputs, giving you options when it comes to hooking up.

It also has a power save mode, with the subwoofer switching itself off when not in use after a period of time.  I actually like it, but I have read some reviewers complain that it is irritating, as there is a click then a short delay after it switches itself back on before the bass kicks in.  It does it so rarely that I’ve never really found it annoying, but you can switch the power save mode off anyway, if you don’t like it.


Brief Guide to Buying a Subwoofer

Your opportunities for obtaining the best subwoofer for your requirements are much better if you have a reasonable grasp of the basics of what all the various specs mean – that way you can buy the most suitable sub for your audio system and room.

Audio power comes from bass frequencies, so the value of subwoofers should never be underestimated. Here is a short  guide to the specifications that you are most likely to encounter and what they mean in practice.

  • Power – The main thing to be aware of when it comes to power is that, in general terms, the more power you possess, the better. Possessing more power doesn’t mean that you have to operate the sub at higher volumes (unless you want to!), but it does mean that it will usually perform better than a unit with less power at the same volume. Power is typically measured in watts, but there are some extra complexities when it comes to amplification.
  • Size – Usually, a bigger driver will give you more lower frequencies. Subwoofer drivers are usually around 12 inches in diameter, but can be larger or smaller. The driver size is not the entire story, however, as power is also important. Essentially, that means the smaller the driver, the larger amount of power it needs to deliver the equivalent amount of bass.
  • Placement – If volume is your priority, then placing the subwoofer against a wall or in a corner will give it an increase. It won’t necessarily be great for audio quality though. The ideal way to get best placement is to sit in your favorite listening position and experiment with the sub out in a vareity of places. You may be surprised how much the output will vary in tone and quality when it is coming from different locations. That’s because bass sound waves are long and so will interact with the size, shape and acoustics of a room fairly dramatically.

Minuses of the SA-W2500

I can see how the power save mode might be irritating to some, although I personally don’t generally mind it.  You do also have the option of turning it off and simply having the sub switched on or off.


Conclusion

The Sony SA-W2500 offers fantastic value for anyone looking for a budget subwoofer in my opinion – it fills my medium-sized living room with deep bass, just as required, and I am more than satisfied with this buy.  I hope that you enjoyed reading my Sony SA-W2500 Subwoofer review and found it useful.
