I think dual 15's would be kick ass. Easier to figure out and tweak and implement too. Do a 3 way xover do you can roll one 15" off sooner than the other might be helpful.

The above and below 12s could be a nice option, even dual below only. I just really like that TD15m

Not really a need to...it is a 3 way, remember, the BMSis a coax and active cross between mid and hf section in this build, then the dual 15s. The woofers really werent' the issue. The units we ran at the gtg were test units and the quads had never been run "live" before, only done on paper. I believe more of the "issues" were the details on the coax honestly. If gone as far as to talk with Ivan Beaver fro Danley and had looooonnngg conversations about it and their implementation of it in some of their units. The general concensous is that you can't get it perfect without going full active. I know some will oppose this view citing the JTR gear that uses it, but I'm not convinced the JTR offerings that run the 4594 wouldn't be even better if they were run this way.

I'm with you 100% on that. Active is better than passive, even with the perfect passive crossover there is an advantage with active over that.

Ultralight mdf is not more substantial after that plyboard as well as the chaos isn't to be able to negative. This reductions more exact then plywood I've found. My cuts tend to be dangerous. Simpler to paint also.

I have been waiting a long time to hear the words that you are back in the game. Heck, I wanted to scoop up some of the gear you were selling, but I couldn't bring myself to taking it away...I knew you'd be back! This was by far my favorite thread to follow, simply because it was pushing the limits of DIY and what could be done. Glad this thread is back on top of my subscribed list.

Thanks man, much appreciated! Through all the nonsense, I forgot how much fun even just speculating and planning is!

Your second to last statement is why I went with the quads originally....I'll never see close enough to the limits of the dual 15s to experience any negative effects, but the the dual model isn't really outlandish in te diy arena these days, so I got stuck on the quads as a must

The BMS can get close via passive, but active is needed for perfect response. I use a combo active/passive filter for the BMS/SEOS24 combo.

I agree with the AE TD15M being used under the SEOS24, anything smaller would be weak looking. :-D

How about some 18" AE woofers instead?

Where to source the BMS for any reasonable amount?

I honestly thought about it, but not chasing full range, I wonder if the 18 gives something up to the TD15 in the midrange (John swears the 15M is the best of all his woofers) and really not getting any benefit.

Pretty much as Face said..pay $700 or get a group buy going. Jack as Assistance Audio, though I've had my differences with him, will give a bit better deal than that too.

It's just physics. Plus the 18" would beam sooner, pretty early actually. You'd need a LOW crossover to prevent that. 15" better to reach up to 600hz handoff.

I didn't mean like that mike...I meant within the operating range without those issues, the 15 is a better driver in many ways according to John. ...Btw the 4594 seos24 performed just fine well below 600. ...I have to pull the files but if memory serves, 450 or 500 is what we were at

950Be is a 2" exit. 951Be is the 1.4".

I tested a (used) D2430K & it looked very good except that it had an intermittent buzz or rub at LF...probably why it was used. The 2430 is a "push-push" design with both diaphragms working full range of the driver. It is very different from the BMS coaxials, but lots of potential for an excellent system.

Just keep in mind it won't work as low as the BMS coax unit.

There's also a SEOS-18 with a 1.4" throat. It doesn't look like the 1" model, but more like a smaller SEOS-24.
