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.

I do notice a difference between standing and sitting. In fact, I now listen standing up, at that aforementioned 4 ft away position.

I will certainly take you up on the cables - I ordered a garden variety on Amazon but can return that.

I noticed that Ethan Winer is based in CT - Cool! I am only a state away in MA. Are you the jazz saxophonist Bob Reynolds who I see on Wikipedia? If so, I am impressed and even more grateful for your time.
One thing I am curious about is why my setup responds so well to high-pitched instruments such as violins and trumpets, which sound really loud and lush, whereas solo piano sounds a lot more muted. With the former, I can barely push the volume up more than a quarter way, or wife complains, With solo piano, I went up to max volume and it did sound loud then, but the loudness was a lot less pronounced and the sound jars a little. The mid level speakers are the main ones that seem to be pushed in this case. Is it normal for piano to be less loud than other instruments.
