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.

A better amp will do very little to fill that room. Find the best sub you can for the money and then get another. Learn all you can about eq's, room correction and time delay.
Shugho,

Can you take an M series amp home for trial? I'd suggest you at least try it for a weekend if you can. I am not saying it works...but at least you have gone well up the NAD range to see...and if you get the right result...you can determine which NAD amp you can afford (and whether it will be enough).

I do think the sub is also definitely worth a trial...any sub.

Thanks all for your continued guidance.

ZD, I believe the connections are in phase - I checked them. I rechecked the Oppo settings and changed two - one said Stereo down-mixed which I changed to Front 1-2, and the other said Crossover 80 Hz which I changed to 40. Other than that, I did not see anything worth changing. I think these made a difference in the fullness of sound, but could not be completely sure. I need a way to measure that.

Bob, Sprks, I completely agree that I need to figure out the room correction and measurement aspect before I make any changes. I am concerned that even with my current setup, which is not shabby (I think), I am not getting enough out of it. The suggestions you made will help me get there.

Others, I am open, even excited, about getting a sub and a better amp - after optimizing my current situation a little more`- and need some more guidance on the amp front. I need to determine whether I should go integrated or separate pre-power. I also need some opinions on the brand I can get without breaking my bank (3K) and would to consider something other than a NAD. I once demo-ed a MF M6i integrated which I really liked, driving Paradigm Studio 60s - thought it more musical than an Anthem integrated 225 I was comparing with. I could also consider a Krell 550i as I read good things about it. Beyond that, I am unsure what else to consider, especially when going separate.
