Welcome, my friends, to what is my biggest (literally) project yet.

Curiously, I went into my closet to find my cracked XLS 10 that I've been meaning to fix, and found a box of old CD spindles that had all my speaker programs on one DVD (all sketchups from ver 3 through 6, LEAP, SpeaD and reverse SpeaD, and the HT audio suite. //content.invisioncic.com/y282845/emoticons/woot.gif.aaa6090e619a97b6090d16dd863c5a69.gif

And I know the tweeter doesn't need it's own compartment; that's not what that space is for. It's only there because the mid doesn't need that much airspace; especially not near 1/3 of the enclosure. Any suggestions on that? //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Are you running any subs with this setup?

Also if you have LEAP then you don't have any excuses for using generic crossovers. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Oh no, I don't use LEAP hardly at all; someone gave it to me on a disc, so I don't feel bad not using it. I only use it when I am planning a project out for a long time or need to be extremely precise. That's what I have X-Over 3 for, but for some ****ing reason, it keeps giving me a "runtime error 380 invalid property value" box when I try to load my design.

K, got that fixed. God **** visual basic source code //content.invisioncic.com/y282845/emoticons/mad.gif.c18f003ab0ef8a0d9c27ca78d77a6392.gif

Are the 10's going to be woofers or subs? Seems like there could be issues with subs being built in, such as placement, etc... I'd prefer a separate sub/subs, so they could be placed in the best location as that may not be were the mains are located...

For this project, they will function as woofers.

I was just mocking up a filter...what in the heavenly **** is all pass and constant power? The constant power looks almost identical to butterworth filters in parts, but I haven't the faintest clue on the APC.

Ok, I just told the 2nd order filter to go **** itself, and my 1st order is looking **** good. The response is 6dB up across the board with a little node at 1k from the tweeter (don't know why, I crossed it over at 3000hz...). From 30-200hz, it's up about 8-12dB on average (I am accounting for the lack of power to drive two 10" subs //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif ), which I expected and am hoping that I'm right. The main question is, will a 5.1 receiver (aka inflated 100w/ch numbers) be able to drive these guys?

You should be fine. How are you wiring the 2 10's?

= 2 ohms pre filter?

Just kidding, S--P. //content.invisioncic.com/y282845/emoticons/redface.gif.62fdbfe1a101588a808c4cff71bcb942.gif

Muahahahaha //content.invisioncic.com/y282845/emoticons/naughty.gif.94359f346c0f1259df8038d60b41863e.gif

This is pretty much how she'll be from here on out. The only thing I'm worried about is the tweeter chamber resonating. How should I fix that? Brace that as well? Lemme kno!

i would be worried about you being able to run all that from your 5.1 receiver...i have a pair of older klh floor-standing speakers (similar to the 9250b's, but with 15's) , they were weak off a High Current Cambridge audio azur(150w at 4ohm) and it looks like you should be demanding more power than that!?
