Two Subs?

A kindred spirit: room correction, Tommy Emmanuel, and Frank Vignola. My Ryan Thorell archtop is one of my favorite guitars (tho it's not the Vignola model, it has a strong family resemblance). And I fully agree that when you clean up the lower registers via room correction, the personality of the guitar being played is much more recognizable.

So true!
Brings a whole new experience to the table.
I never knew Rodrigo y Gabriela could sound so good and precise. Like sitting third row center and getting the live sound from the stage!

Wow! A Thorell Archtop!
Serious player, no doubt! :-)
Nice ...very nice!

Rodge - don't know if you want to weigh in; but thread in Tech Talk forum is discussing performance of Dspeaker

Rocky, Based on everything I have read concerning the use of subs, 2 are better than one, and can be more easily positioned for better bass response even without room correction. This has been stated by other posters prior to 10/17.
Let us know what you decide.

Rockyboy,
I read through the thread and I can't comment on the clipping issue the one guy is having. The only clipping issue I had was from my former dac that had a 5v output and clipped the analog input. There is a sensitivity filter that can be placed on High or Low for this issue, and it worked for me. I have read about the MiniDSP and doing measurements with REW, but found the Dual Core 2.0 to do a very good job and never felt the need to go that route. If budget is an issue the 8033sII is a great product and should be seriously considered. I have the 8033c on my HT sub(SVS 2039+) and like what it does there.

I had read numerous posts and some papers about sub placement and tried to implement those techniques. It was a lot of work and in the end the Dual Core did a better job. I'm very happy with the sound quality with the subs placed in the r&l front corners of my listening room. If I could I would place a sub in the front Left or Right corner and a sub in the opposite corner on the rear wall. Play around with measurements and calibrations until I was satisfied with the bass.

"If I could I would place a sub in the front Left or Right corner and a sub in the opposite corner on the rear wall."

That would very likely be a bad choice as both subs would be exciting the same room modes. One sub in one corner is good, but the second one should not be in the symmetrical corner. Moreover, about midway of a wall would be more advisable.

The best configuration in my room has been one sub in between the main speakers and the second sub in a corner, with the front or back corners showing almost the same results (albeit with different settings/adjustments).

BTW, just like there is no substitute for good speaker placement, the same goes for sub placement. Sure, room correction will make it better, but the least correction you need to apply, the better.

Cheers!
