I ended up doing the active, quad-amped PT250 instead, with a big dose of help from a friend who had lots of time to tweak the active crossovers.
It'd be instructive to see a cross section of the modded 240Ti cabs he's using. I've got to believe it's two separate chambers; otherwise, it's a tuning nightmare. Are the sloping boxes on top for time alignment? Or would I need to sit in a high chair to be in the sweet spot?
There's a lot of ingenuity present, along with some good cabinet work, but it really doesn't call "Own me!" to me. I wouldn't mind hearing it; I don't think I'd bring it home.
I was thinking along those same lines. A five way...I know I would pass. And even though the cabinet work is nice, I just don't like the box on box look.
The sloped top baffle would certainly be for time alignment, but he does not give any dimensions. But the fact that the 240 box by itself is 36" tall tells me the entire thing is too tall for a sloped baffle.
Think about that 240 box...that was a complete system by itself...36" tall...just slightly lower than my 212s on their original bases.
So then there is an 8" driver, 4" MR, 1" tweeter(which actually another 4" in total diameter). So there is another 16" just in drivers added, plus the spaces in between. So that adds up to around 56"+. Its one thing to have a tall speaker and quite another to have the tweeter/midrange firing over your head when seated.
Which, on that subject, on a closer look, and based on the C~C dimension of my 8"~4" drivers, he has those drivers too close together.
And when it comes to tweaks that improve a system, I put time alignment way down the list compared to mirror imaged boxes(which produce a full soundstage), biased crossovers(which improves everything), pro midrange driver(with more power handling ability) Which he does have some of those things...but 5 drivers and a sloped baffle that too high screws up the mix.Edited by 4DHD - 6/3/13 at 4:59am
