Do I need a subwoofer? Which brand and model?


I mainly listen to classical and jazz - mostly trumpets and violins, with the occasional piano, viola or bass guitar. A couple of my friends have been suggesting to me that my ensemble lacks bass and having a subwoofer will address it. My setup includes a 2 ch. NAD C365BEE integrated amp, Wharfdale EVO 50 loudspeakers (pair), and an Oppo BDP 105 Bluray player as a CD player. The setup is in the living room, with three walls, and the fourth side open to the dining room. The living room itself would have been 18' L X 12' W X 18' H = 3888 cu. ft, but the fact that it opens up to the dining room makes the entire space more like 40' L X 18' W X 12' = 8540 cu. ft. Would I benefit from a subwoofer and which one should I get? Budget $1000 or close to that.

Several good brands are available on-line and offer a free in-home trial period. I'd agree with Lloyd that your space is large and that a subwoofer (or two) would likely improve the tonal balance of your system, but a free trial allows you to satisfy yourself.

One very appealing offer comes from SVS (svsound.com), which shows a pair of sealed 12" subs for $950 (last I looked). The SVS subs have an excellent rep, and a pair of subs is likely to get you smoother in-room response than a single sub. If you do want to stick to one subwoofer, you could check out Rythmik (I use two and am completely satisfied) or HSU (another brand with a good rep).
Thank you Lloyd. I will try a more powerful amp if I can get one. Good suggestion and thanks for the detailed explanation on the physics.

Marty, I have researched the brands you suggested. My options are a pair of SVS SB1000, a single SVS SB2000, a single Hsu VTF 15H or ULS 15, or a single Rhythmik F12.

The Hsu VTF 15H or ULS 15 are the best deals at the moment - a Black Friday special.

I would rather buy a single higher end now and add one more later.

Please let me know which one you think fits my need the best - my needs are musical rather than movies.
Lloyd, When you suggest a more powerful amp, what level of power should I consider? My NAD 365BEE is 80W per channel. I could consider something like an Anthem integrated amp at 225W per channel. Should I consider other brands or wattage as well? My spend comfort is around 2K. Thanks again!
I have OPPO BDP-105 , I think you will be happy with HSU-VTF15H. I am very happy with this.
