Can I make a crossover or buy one?

Tried posting this last night, but for some reason, my connection went down. Maybe my server needs Viagra : )

Jimmy, the closest thing that i could easily find would be part number 260-221 OR 260 - 220 at www.partsexpress.com One of those is designed for an 8 ohm system and the other is for a 4 ohm system. The 8 ohm crosses at appr 150 hz ( kinda high in my opinion, but... ) and the 4 ohm at 130 Hz ( same thoughts here ). It also provides outputs for the monitors that attenuate the lows at a rate of 6 db's per octave at the above mentioned frequencies. If you have questions about this, snag their phone number off of the website and give them a call tomorrow. Ask for Sean in technical assistance. NO, it's not me : )

You might also want to check and see what Madisound has to offer. They can custom build crossovers to your specs at pretty reasonable prices. I had them do computer simulation for the installation in my car after i gave them all of the driver parameters and mounting locations. Their website address is www.madisound.com If you need technical help, they have an excellent forum. You could also call them. If you do, ask for.... Nah... i don't think that a Sean works there, but you never know... : ) Sean

I've been racking my brain for 2 weeks..here you just ask, thanks!

Yo Jimmy,

You might want to consider the Parts Express subwoofer amp with built-in crossover. Go to:

It would require cutting a hole in the back of the enclosure and soldering a couple of wires to the speaker terminals but it should solve the problem.

If you want to go active, check out Marchand. Make sure you read through what they have to offer. There are a lot of upgrades and different options. Everything is also sold in kit form if you are a DIYer. Don't see what you need? Give Phil a call. I have a full blown tube x-over by them and it is phenominal.
