Two Subs?

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!

First the professional microphone which is used with Audyssey pro measures a lot more information compared to a standard Audyssey microphone. Second we measure at totally different places and hights compared to the Audyssey way of measuring. This gives a very big difference in how much dynamics and information you can measure. The roomcorrection of Audyssey is only 1/3 of the whole system. By using the parts Audyssey volume and EQ to the max the end results are a lot better. Without it I would have a loss in dynamics. And it would be more the same like other room acoustic systems. By using Audyssey pro with EQ and Audussey Volume the volume of the sub can be set so much lower than without. This gives you more control and more drive as well. We learned to use it differently to get the results we wanted. Using the sub till 140 hz makes the palpable integration so much better. People Always say and think; so you do not use the subwoofer? Ofcourse I use the subwoofer. When I put it have you see the eyes of the people move. Using it till 140 hz is only possible of the timing and fast respons of the subwoofer. Next step will be the very Soon outcomming pure silver Audioquest Wild Dog subwoofer cable.

Bo,

Audyssey requires that the subs be calibrated at 75db, IIRC. If you're using a pair of reasonably high quality subs, that requires quite a low setting, right there. The volume dials on my Rythmiks are set at the very low end of their range. I can't imagine going much lower.
