Depends.

What are the subs? Community XLT55's
What are the tops? Behringer B215's
What is the crossover? Internal crossover in a Crown XLS2500 power amp.
How much amp is available to power everything? There will be 1200w available to power the subs (2ohm load/1 side of amp) and 775w available for the mains (4ohm load/other side of amp).
Note: There will be very little outdoor use. Mostly indoor Bar/Club/Restaurant use.
Start at a 100hz. Then kick whoever the idiot was that thought 215 cabs would be a good idea in the sack. EDIT- The owners manual for the subs say between 100-150hz for best results
Well, the subs came free! Can't afford to buy anything at this point so we gotta use what we got!
Let me clarify, I just needed the crossover point for the subs because the amp asks what frequency point do I want to use. I don't recall it asking for one for the mains (I could be wrong). The subs have dual 15's. The tops just have single 15's even though the model says B215. By the way, the amp is pretty cool. It can be configured in quite a few ways.
Stereo Bypass Mode (Default mode/Mains only/Stereo input)
Bridge Mono Mode (Sub only on 1 side/single channel input)
Crossover Mode (Subs 1 side, Mains 1 side/single channel input)
Highpass Mode (Mains only/2 channels/Stereo inputs)
Lowpass Mode (Subs only/2 channels/Stereo inputs)
Stereo Bypass Mode (Default mode/Mains only/Stereo input)
Bridge Mono Mode (Sub only on 1 side/single channel input)
Crossover Mode (Subs 1 side, Mains 1 side/single channel input)
Highpass Mode (Mains only/2 channels/Stereo inputs)
Lowpass Mode (Subs only/2 channels/Stereo inputs)
It's not a 2x15. That's just the model name of the cab. It's a single 15 main.

Here's the amp.
yeah, we're just talking about 2x15 tops in general now, nothing to do with your stuff 
they're too big to pole-mount, too short to get the horns high enough when on the floor, and when stacked on a sub the bottom 15 loses any reason for being there.

Basically, they're what happens when marketers say "more is better!"
It isn't always better.
Funny. One of my other bands had them (JBL dual 15's mains) and I had to convince the owner to ditch them. He had a problem with them once and he rented some Yamaha club series single 15's! What a difference! He finally sold them to a pawn shop and is using the Yamahas now!

We ended up with a pair of JBL 2 X 15's...not my idea, mind you. I have a pair of Quick-Lok stands which should work nicely once mod'd. The footprint once the "spider" framework is extended is too wide for the relatively narrow enclosures. I'll have to devise some type of removable, lightweight shelf that can be dropped in place before hoisting the cabs.

Depends on the drivers in the whole system and where they operate best. You can want to use speakers in a specific range, but that doesn't mean they'll do it well.

Here's the amp.
Do you know how to control that amp? If not, read the manual, then re-read it. Until then, you won't really know what it's capable of and how it can work for you. It has compression, limiting, crossovers and IIRC, it can do parametric equalization.
Leave it to Behringer to call a loudspeaker 215 when it only has one speaker in it.
But it has two ports.
Almost a good idea but I need something with dowel-esque alignment pegs to stiffen the contraption. Problem is that I bought the things secondhand to save a bunch o' dough and the main cross-member connecting the two sets of legs is waaaaaay too wide. If I angle the legs inward adequately, the structure loses stability. With God as my witness, I will make this work....and I shall never go hungry again (Scarlet O'Hara).
Oh.....100 hz is a great starting xover point. DW, I owe you a visit!
