    Dual VOT A7 Cabinets Good or bad?

    A long long time ago I had an opportunity to buy 16 ohm JBL woofers that were used once for a concert. I had passive crossovers at the time so my solution as a very young man was to build a second set of A7 cabinets so I could parallel the 16 ohm woofers. Now I want to use Altec 416 woofers... So the question is should I load all 4 cabinets, two on each channel. Impedance isn't an issue now as I use active crossovers. I am wondering what the plus's and minus's are considering mutual coupling issues. Given the large size it is enough of a wavelength between drivers to cause havoc...

    Hey you could stack em!

    I am curious about this also. In the near future, I will have four 828 cabs in my listening space.

    Thats the way i'd do it, top to top so the acoustic centers are as in close proximity to each other as possible.

    I have a wall for the last 30 years where they have been side by side... Before I moved the current house they were stacked... horizontally though... kind of stuck with the side by side.

    I just added a picture of what I had. I will re port the cabinets and remove the burlap on the A7's. There was also a curtain which won't return...

    Oh wow, that is quite the setup you have.

    There is a lot of gear on that side wall.

    I see a first series PL700, and a small Crown like a D60 or D75, and a couple other pieces i "think" i recognize.

    Yep.... a pair of rack mounted McIntosh 60's for the horns PL 700 modified for the woofers and a Velodyne ULD 18 for the sub... The Crown is just stored there..

    That's a really nice install. i love how you flush mounted/half spaced the VOT's. Given the space, i think it's an ideal arrangement.
