Got a good start on them today
The crossover looks awesome, might have everything I need.
Thanks again!

For those that don't know, the white ones in post 6 is Dissi's crossover design; that's a heck of a speaker. Wow they have some punch! But also do well with detail. Have three in the HT, two vertical and horizontal center.

Bachelor for the last couple of days, so had time to work on this
I keep finding the 5" woofers, I know another buddy with some; a lifetime supply of them.

Found a pair of 2.5mh inductors, I'm sure I can find the other xo components.

Went back and fined tuned the size vs. ports, with WinIsd and box program; boxes are 22liter (excluding ports) vents are 11mm x 6.5" wide x 6" long. Fs 50hz.

We HAVE to get you to start using better drivers!

How about the Santori woofer and the Transducer Labs tweeter?

I am back from NC and the crossover parts came in for the SF/Daytons. You are going to hate them. This is what yo get with a mid quality woofer and a mid quality tweeter with a simple crossover. I think it proves you need better drivers.

I'll getting good vibes about this project, think it's going work nicely.

TVR, the speakers on post 6 crack like lighting bolts, they cruise along delicately - just waiting to unleash their fury (funny but accurate)

If you can't use the SF's there are extra mtm boxes here

I have not exhausted what I can do with a "simple" two driver system, so I have no desire to make things as complicated as MTM. I actually need a slightly smaller box for my office than the Seas ER18. The Zaph drivers were a bust.

I'm finding the double woofers boxes have more of what I've been looking for.

Dissi, thanks a million for the design, I find all this fascinating.

Need to finish up...wife will be back from the beach trip soon

Success! They sound great, really nice balance, crazy nice bass.
(the 2951 Peerless was always known for good bass)

They sound a lot like the bigger 6.5"s - remarkably.

These dual box box are the way to go as far as I tell. They blow all the other boxes I've been making over the years - right out of the water.

Now I don't think the woofers are broken in yet, I'll give them a few more years

So this was a hit, good to hear the xt25's again. Liking this idea of 2 - 5" woofers.

Basic xo question, not sure of the word here and/or this is correct, but does the cap/coil compensate for the impedance curve?
