Are there any 3way componet sets out there that bandpass the midrange and highpass the tweeter? I am looking to do a hybrid active setup.

It would be best if the midranged was bandpassed from maybe 600k-2,500. I plan on using DLS UR 2.5 (or the iridium 3" if I can find it used) [I will also entertain other dome suggestions that play well off axis]

I only have a four channel amp, so I figure 1 set of channels for midbass, another set of channels for midrange/tweeter, but I cannot find a passive crossover that works that way.

Any suggestions?

The CDT models I checked cross way too low, around 250 hertz. I do not know of any dome that plays well that low.

I know of cones that go that low, but I don't think they play very well off-axis.

You can use ANY set of xovers and use a HP on the amp to bandpass the lower end of the midrange.

You're not going to find much, if anything at all. The Iridium crossovers crossover at 400 hz and 5500 hz, and the UR 3-way is 450-5500 hz. Those are the only ones I know of though.

Most decent 3-way crossovers bandpass the midrange. There is one thing you need to be aware of as well, though. You really shouldn't run a crossover with one section not being used. In other words for a 2-way, you should never run just the mids and not the tweeters. You can blow caps and stuff.

Your best bet is to use a 2-way crossover, and use the amps internal crossover to high pass the midrange. Hopefully you have an amp capable of crossing over to 500 hz.
