2 XSubs

[Ron Temple]

John G brought over his soldering gun and we put a replacement Cadence driver into the 2nd unit. Everything checked out fine, so now temporarily I have two.

I stacked the units, so, colocated, I got the 6db bonus. Recalibrated, then demoed some movies and music. 2 is definitely better than one. My room is saturated with bass and I probably picked up a couple of hz.

I don't think there's any cancellation, but the peaks in room are more noticeable. Sounds fine from LP.

Any tips from dual sub owners that don't require new placement? This is temporary. I'm too lazy to move holiday decorations.

Two of these guys are getting pretty close to what I remember John's PB10 sounding like.

.....you and Buck really know how to hurt a guy, Ron Temple, haha.....when you can after the Christmas tree and ornaments are taken down and back in storage in about April, put both Cadance's on the floor, in the front, split to your tastes, supporting the soundstage....this is especially necessary with two front-firing subs....they will have direction and localization no matter where they sit, and that's good....hooray for two....hello balance.....

I recommend a balanced placement.

I don't know what your room looks like, or the stuff in the way, but one on each side of the TV would be a mighty subwoofer setup IMO. I have one to the side, and having one on each would well.... be organsmic. I don't have a balanced room though (stupid heating pipe made a long rectangle along the top right side, that causes the bass to be heavier on that side).

For movies, I perfer a subwoofer beind me, rather then infront. Music however I like it infront.

Basically, I need 4 subwoofers. 2 behind, 2 infront, and a switch

Hope this Helps,

If I remember correctly Ron - Your room is not setup like a typical square/rectangular room.
And by putting 2 subs up front is not really possible for you.
Your seating was more like a diamond shape, and the kitchen wall - will slightly prohibit the space needed for the second sub.
By stacking them - I would beleive that if they are cut high - then you will still have localization issues.
At this point I would say as the others said - that a equal soundfield would be best.
So my recommendation is to put them one on each side of your chair.
Or in the farthest corners left and right of your seating position.

Also you had replied to me in this post. But reread it. Or at least the last post I have in it.

I tried to post pics, but just a few too many pixels for an attachment here. Basically the room is 18x14x8 with a 5' opening stepping up to the dining room. My fronts are off center on the 9' wall, subs stacked to the left of the media center tucked between my floorstander and the opening.

I'm sure you're right about balanced placement, but I don't have room on the other side.

The bass is not localized. I have the fronts cut at 40, the rest at 60. There's a null while sitting in the LP, but it sounds great. If I stand, I can taste the bass.

These guys really perform well. I haven't told my wife yet, but , they are going to my boys for Xmas and I'll be moving out of the budget arena.

My wife pulled a Buckeye in my room. A picture is on my thread over at AVS. I now have 2 snowcovered mountains on my mantle where my surrounds used to be. Still work fine though

Thanks for the advice guys. If I get some time with no one around, I'll de-couple them and see what's what.

Me personally, I'd leave 'em stacked and drop them both in the corner behind the entertainment center. That would be the first thing I'd try. They'll also be more or less out of sight then too. If you shifted your entertainment center a bit, you might be able to squeeze the second one in on the left side, but if they're leaving at x-mas they may not be around long enough to try that.

Did the Darla tap at -15, absolutely no distortion, but the back panel on the EC nearly rattled off, right around 100db. Placed behind the EC, I'd either have to remove it, (probably not a good idea) or find a way to silence it which maybe tricky as it's such a big piece.

Slap a couple more big nails into that guy

Maybe, that single-ply stuff in big sheets leaks air though. Why don't you stand behind it and hold it for me. That'll work.
