OK, I was going to purchase the fusion quad 4 from DIYSound Group, but its out of stock and the more I thought about it, they were just a little on the small size. I will purchase them in the future for surrounds either sides or for the rear. I am wanting more of a tower speaker. So i did a little research and decided to go with (per tower):

4 - Dayton Audio DC160-8 6-1/2" Classic Woofer
1 - Dayton Audio D250P-8 1" Polyimide Compression Horn Driver
1 - Dayton Audio XO2W-3K 2-Way Speaker Crossover 3,000 Hz
2 -Speaker Cabinet Port Tube 2" ID Adjustable

Design 1
60"H x 10"W x 10"D box

port
speaker
speaker
horn
speaker
speaker
port

The bottom port is 12.5 inches from the bottom and things are spaced pretty even to the top.

Been in contact with Parts Express Tech, they suggested an L-pad on the horn.

Will post picture of design later when I get home. I had another idea for a little different design and had a question on the ports; will it change anything if pointed out the back vs out the front?

Did I miss anything so far?

Thanks for any and all advice!

YES! You cant just use an off the shelf crossover with random drivers. The recommended L pad is seriously just like putting a band aid on a gun shot to the chest.... PE wants you to buy stuff, they arent capable of designing a crossover without building a box and measuring the specific drivers. That's what you need to do if you want to go the custom speaker route.

There's more kit options then DIYSG or PE

I read your comment and went back to my figures and seen errors back to the drawing board.

Did you buy anything yet? It not, I urge you to hold off for the time being. Besides everything else, you don't want to make a square cross-section because then you have a double resonance at one point (in this case, 1/4 wavelength about 400 Hz).

What are your goals? You should do some research and think about building a proven design first.

If you like the idea of an MTM about this size, here's one to look at.

Mandolin MTM:
(much pricier but would be very clean with deeper bass)

Bad news is I have all the stuff that I listed and more.

Good news did not buy or cut any wood and I ordered on Wednesday morning and received on Thursday afternoon. So on Monday, I guess it will be going back.

So I guess I will wait for erich to get the fusion quad 4 back in stock. Been in conversations with him since end of January so hopefully soon.

You are saying that going off the speaker statistics for hertz range, cubic foot requirements, what you want (2 way, 3 way or what else is there) you can not build a crossover to get results that will work?

The published TS specs will let you design the box for the woofers. You need full impedance and frequency response measurements, measured on and off axis, to design a decent crossover.
