Vandy 2WQ bottoms out with movies

Thanks for the responses.

Steve, thanks I do love my system. I am baffled with this problem (disapointed actually). I have the temporary crossover in place right now. It is a single ended crossover. I will get the balanced version to use when I decide which crossover I require. Having said that, this shouldnt be the problem.

Do you guys think that the Bryston SP1.7 will send LFE signals to the 3A/2WQ as well as the the LFE sub (V2W) with the main speakers set to "Large"?

I have Bryston balanced interconnents for all of my channels but have used cheap single ended cables for the temporary sub crossover. Once I know which one I need I will replace the it with the balanced version of the crossover.

When I hooked the sub up the as noted above, the levels for the main speakers and the sub were way out and had to be readjusted on the SP1.7. Why?

Right or wrong, I know that many people that are more into music than movies have chosen to use a pair of these 2WQs rather than going with the V2W with no issues.

Again, my suspicion is that when the speakers are set to "large" on the SP1.7 it sends LFE info to them as well even though the processor is set with a LFE sub active?

I used Digital Video essentials to set the levels. When I did so, with the setting as described above, the sub pink noise went to both the V2W (LFE sub) and the 2WQ.

When I use the SP.1.7 pink noise it only appears on the LFE sub.

When I turn up the level for the LFE it appears that not only does the V2W (LFE sub) get louder but so does the 2WQ that is being used with my main speakers.

Dhel, I have actually tried turning down the "Q" with the thought that it should reduce the amount of the bass thus not bottoming out the 2WQ. Problem was still present.

Albert, I hear you on being tempted to crank things up for movies but that isnt my case here (at least not intentionally).

Your help would be appreciated.

Flrnlamb, I dont disagree with your opinion at all. I am just very surprised becuase if you know anything about the Vandy subs (2WQs or the V2W) they are quite highly touted. The V2W (meant for HT) handles things just fine.

What I found out though (and it doesnt make any sense to me) is that EVEN WITH my Bryston processor set to have a LFE sub, with my main speakers set to "large" due to using the 2WQs with the main speakers, and all others to "small" the sub level control on the Bryston controls the level of bass going to the large speakers!

That just doesnt seem right to me! I know that the sub level control is intended to control the LFE channel and redirect the "small" speaker info to it..but...?

I wish someone with a Bryston processor could tell me whether theirs does the same thing.

Swampwalker, my thought was that setting any of the speakers to "large" will send full range signals to them but NOT LFE and the bass below the cut off frequency of all of the "small" speakers.

Well guys I am not crazy after all (not that anyone said I was...I was just starting to wonder myself as this problem didn't make sense).

After much playing around, I contacted James Tanner of Bryston and ultimately one of his "experts" Mike Picket. Well they were gracious enough to research into the problem at the factory.

After trying to replicate the problem Mike called me back saying "I can't believe that it took this long to find that there was a problem!" Apparantly no one else had ever complained of this. Bottom line is that it isnt my sub's problem at all. It is a software issue with the Bryston SP1.7 which they are going to fix.

You see when the SP1.7 has the main speakers set to "Large" and the surround set to "Small" the bass below the crossover point for the surround speakers is redirected to the main speakers. Here is the problem, the level control for the LFE sub also incorrectly controlled the level of bass that is redirected from the surrounds to the front speakers.

I had the sub level set at 6.5 (for the LFE sub). This was all fine and good until it incorrectly cranked up the redirected bass to the main speakers sub...boosting the level too high!

My temporary fix is of course is simply to reduce the SP1.7 LFE sub level to 0 and crank up my level control on the LFE sub to the appropriate level.

And, as I speak...guess what...my SP2 has arrived!

Thanks for all of your insight.
