Re: Sub Crossover
Yes, I still use this crossover. I tried several different units but settled on this one.

Subs and crossovers
I remembered that you had subs over the years, seems like you had Tent Sale 2245's didn't you? Then again, even if you did, those are huge. I also seem to recall you had a Titanic sub or two. Any of those would work just fine. Or maybe build smaller ...

Re: Group Build National Semiconductor amp
I'm still game. We never really did anything with this last time, but I'd definitely still be interested. We could probably buy from Digikey, just pool together to make one order. I'd buy several all by myself. Do you think we should make a post on the...

Re: Active Theater 4 Bi-Amping
Yes, that's a good way to split them out. It would be pretty easy to amp the woofer separately from the mid/tweeter in a π cornerhorn. Same idea as the sub/mains split I mentioned in the last post. That way you keep the passive crossover that's used in...

Re: Subwoofer Kits
The three π subwoofer kit includes a PI-12 woofer, wired connector panel and a printed copy of the plans. For a crossover, I suggest something like this:

Multi-sub Crossovers
For those of you wanting to experiment with the multi-sub concept, I found an inexpensive crossover that you can use. Get one or two of these and use them with existing amps. If you don't have amps, this won't help, but if you do then these little cross...
