Mw6510

Something still wasn't right with the right 1C...just not as alive or dynamic. Steve gave me permission to swapout the drivers in the CRS+s. I was really hoping it wasn't the crossover. I replaced all 4, noting after speaking with Steve and looking at his copy of the compendium that the 6511s & 10s were stereo/sda drivers on the 1Cs and just the opposite on the CRS+s. So Friday I checked it out and there was considerable difference. The right side came equal in impact and pop...I'm so glad. Today I checked the CRS+s with my drivers installed and they sounded pretty good...slightly off on the right again, but good. I found that the 6510 stereo driver wasn't pushing nearly as much air as the other 3...so I think that's the culprit. I'm not sure why, in the dimensional array config this driver would throw the 1C off as much as it did. The CRSs don't sound nearly as unbalanced.

Any thoughts?

That should be a dimensional driver in your 1C's, or are you talking about when it was in the CRS+? If you swap your 6510's does the right speaker sound better and the problem shifts left?

The 6510 used as a stereo driver in the CRS+ right is weak. I'll take your suggestion and pop it into the 1C left and see it it effects the sound...should have thought of that. I will say the CRS+s didn't sound nearly as unbalanced. Just placing my hand an inch in front of the drivers, the other 3 drivers had equal sound pressure. Then checked the 1Cs...they were all working equally hard (if I'd done that first I could have save a lot of time). There is sound coming from the 6510 and it's clean just not equal. I wonder why it's losing it's values compared to the other woofs.
