Default Electronic crossover question

can anyone point me to an electronic crossover that will work with a 2way speaker (ie. hi pass, lo pass for midwoofer and hi pass for tweeter)?
i've not had one in my hand but of the dozens i've viewed online, every one has only a ~50 - 300hz lo pass and ~150 - 5k hi pass. that would work i i was adding coaxials to a sub or maybe running the mid full range and adding a crossover to the tweeter ala 1.5way but have yet to see something with a
1k -5k lo pass.

not worried about lo passing my sub, that's under control already.

if you know of something please add a link.

David

You should find both a high pass and a low pass filters at the same single point. That is what makes a crossover!

I think you might be confused by some terminology.

If you get a 2-way crossover, you will have a low and a high output. They will both center on the same frequency. The low side is a low pass filter and the high side is a hi pass filter.

It can get even more confusing when the same device can be 2-way stereo or 3-way mono, or some other variation on that idea. You really need to understand how an active crossover works before you read the manual for any of them.

I do not have one, so I cannot speak about the exact function, but I know that Behringer makes an all digital device called the DCX2496 Ultradrive Digital Crossover System that is programmable to be just about anything you might want.

James.

this a car audio issue so i don't think the 2496 will work here. does it come with 12v option? if so it would be great for the job.

you could be correct that a single setting does the mid lo and tweet hi pass simultaneous but every unit i looked at called the setting a hi pass. no mention of lo pass and the few pics i could see of the output stages didn't have enough rca's to accomodate four amp channels.

maybe like you infered, i am overconcerned about a non issue, but since no-one in my town carries anything like this i will have to order one on line and i don't want to get something that won't work for me. do you think something like this will work?

Amazon.com: Sound Storm Laboratories SX310 2 Way Electronic Crossover with Remote Subwoofer Level Control: Car Electronics

here's an example of what i was referring to with regards to not enough outputs. unless i'm mistaken, with active crossovers, doesn't every driver need a seperate amp channel? this only has two front outputs and two rear.
