ZM,
I didnt see you had posted the pic of the 210. in brochure, they have it standing up, which i guess wouldnt work, considering its design. Fun it is.

JRKO,
Passive is defintely cheaper, but not as capable in simple form as dsp. I havent made that decision yet, but would probably go minidsp, as I have heard it is more favored than DQX2496. I tihnk the Behringer can be good, but needs mods, and i want to spend time on speaks, not crossover.

Did you account for the increase in Qts the Pass amp's output impedance will cause? If not, you may get that 'flabby' bass you can't tolerate without mucho vent damping.

For best overall performance, woofer choices depend on the HF horn's directivity and XO point/slope.

GM, I will be building the the SS version of F1 and F2 to see about working around Zout issue. Amps I am more comfrortable with and can work around, plus i got a ZM

GM,
From the reading, I can see why one may hesitate to go the MTM route. What should be expect from a side by side and is this a reason to go with a single woofer? In those results, are we talking acoustic or electrical interaction? I noticed you had a pic of WWT MLTL, using 515b's, I believe. I would assume that configuration has its own drawbacks. THen again, EVeryone says it is all about tradeoffs.

Here is interesting link to 414 performance, mainly highlighting its abilities up top in midbass area.

Flex Your PCD Mettle: - Page 45

Don't know that I am taking advantage of the 288, although good extension does possibly allow for slower order xover. have read that most people encourage hig order crossovers, assuming this is for protection of compression driver.

you don't really need so much of protection for them , in home use

all about sonics , because even with few watts on them your ears will bleed

This looked like best config in unibox for single Altec 414.
Will have to use brick wall filter down low, as it exceeds xmax in mid 20's in box this size.
Tried larger box of 100l and it went deeper, but just maxed out faster.

Read some info on Bob Brines site last night and will play with MJK sheets more.
