what kind of speakers do you have that you need to buy a new pair of crossovers for? Best bet would be to buy an active 3-way and use that TMA 4-channel plus your 2-channel for an active setup.

If you do decide to go active, I have an Alpine 3672 active unit tha does 3-way front and 2-way rear. Will sell for $100 shipped

I'll sell you the Audio Development passive 3-ways in the pics I posted for $100 plus shipping (call it $110 shipped including insurance). I honestly don't think you can find a better passive anywhere unless you have one custom made. Keep in mind these crossovers are part of a $2500 set of speakers that were imported from Italy. I never used this crossover because I went all active. IM me if you're interested.

Makes no difference how expensive they are if they don't suit the drivers he's using. If you don't know or understand that, your opinion of how good those crossovers are is pretty irrelavent.

Keep the 4 channel, buy a 2-channel, and buy an active x-over. Otherwise just buy a passive 3-way set and call it a day. Mixing and matching your front stage drivers really isn't the way to go if you don't want to go active and you can't build your own x-over unit.

Do you already have said tweets, mids, and midbasses?

If so, a pre-built 3-way crossover will most likely NOT work well for your setup.

If you still need me to explain why, I can.

Basically, if you mix and match drivers, you need to do two things. First you have to make sure that the drivers have compatible frequency ranges (In other words, you don't want to have a huge gap between the usable frequency range of your mid and tweet or your midbass and mid). Once you have picked out drivers that compliment each other, you need a crossover that has cutoff points and crossover slopes that suit your drivers. You can't change the cutoff points on a passive crossover and the slopes are generally 12db/octave IIRC.

So, unless you design your own crossover unit, a passive crossover will likely not offer suitable crossover points and slopes, so you will not get optimal performance and could even hurt your equipment if the discrepancies are severe enough.

So, if you haven't bought drivers already and want a passive setup, buy a ready-made 3-way set from any of the dozens of quality manufacturers out there.

If you've already purchased drivers that are compatible with each other, keep your amp, buy a 2-channel, and buy an active crossover. This will get the best performance out of your equipment, offers you the ability to tune and adjust your system, and is probably easier than designing your own passive unit.

If you've already bought mix and match drivers and DON'T want to go active, sell the drivers and start over.

Those are your main options unless you want to design your own unit or you get lucky and find one that suits your needs (which isn't likely).

That's basically the situation. I'm not the most knowledgeable person here, but that should give you an idea about why buying a random passive crossover isn't your best bet. I'm sure someone else can explain it with a little more knowledge and finesse if need be.
