The things I can see with the 4" drivers is limited output and limited dynamics. They Dayton's on the other hand will be able to fill the room much easier with less work and power, which also means cleaner sound.

The 6" Dayton actually has less displacement. 680 for the pair vs. 903 for the quad pack of 4" full range.

But I'm concerned about having two 4" drivers side by side. Wouldn't that cause some sort of defraction or other audio issue?

How would the EL70's compare with the 5" Tang Band W5-1611SA 5" Full Range Driver quad pack (two on each side)? I think the price is the same.
Both are a bit more than I want to spend.
Edit: Dang, those W5's just went out of stock until the end of July. That's the second time a driver I've been interested in has gone out of stock!!!!

I really do like the idea of the 6" + Planar tweeter though. I've always wanted to see what those Dayton planars sound like.

I think that you my be quite shocked at the price of the neo magnet TB if it goes the same way as the other neo TBs have recently. If so, the $45 sale price could turn into a $130+ each price tag.

I do have 1611 here, Chris has had a chance to listen to them, i've not yet.

I know, the pricing is crazy lately.
I was looking at some Tang Band subs recently. Normal price was $60 and they were on sale for like $35. Then two weeks or so later they were well over $100.

I have no doubt the price on these 5" will go up heavily within a few days.

At any rate, a pair of these...

Dayton PK165-8 6" Professional Kevlar/Paper Cone Midrange

With a pair of these...

Dayton Audio PT2C-8 Planar Tweeter
Do you think this Tang Band woofer would match up well with the Planar in the way you're suggesting above, in place of the 6"? The Tang Band has 4x the displacement.
Other specs (at first glance) are similar.

Tang Band W6-789E 6-1/2" Woofer

Hmm, how about taking the best of each design and combining them?

Wide dispersion planar tweeters crossed over at 3k hz to a pair of vertical mounted 4" full range with high x-max, low fs and nice off-axis response? Crazy or do-able?

Planars:
Dayton Audio PT2C-8 Planar Tweeter

4mm Xmax 4" Full Range drivers:
Dayton Audio ND105-4 4" Aluminum Cone Midbass Driver 4 Ohm

Picture of proposed layout. And feel free to smack me around and say I'm not listening to you.
PLEASE say it won't work - it's killing my budget.

Okay... It won't work ;-)
Off axis response of planar tweeters are far from the best.
Dayton Audio's much cheaper 3/4" tweeter will do even better.
I haven't tried the 4" ones, but I've got the 3" Aurasound drivers. They can be crossed as high as you want to, say 6-8kHz first order. But mind you, the resolution isn't really that great. For background music, they are wonderful, but if you want something "revealing", they won't do the job. Again you would like to take a look at the Scanspeak Discovery full range
. Cross them at around 200Hz to Peerless SLS or something like that and use that as passive sub.

What's more, we're in the "Full Range" page and I suspect it's better for us to focus on full range solutions. =]

I actually posted here to see if anyone would recommend the Fostex FE206En 8" full range. But I've learned some 8" don't have good off-axis response according to you guys.

I'm not crazy about the idea of a single 4" on each side.

The sub will be an MFW-15 clone and since also used for home theater, will also often be run +10db.

With the relatively small physical separation of the enclosures implied in your first photo, and the large room and listening distances for non-critical listening, how significant would the off-axis response be?

Of the Fostex drivers, the FE166En or even new FF165WK might be better candidates. As the mains and woofer will be in such close proximity, I doubt that crossing over as high as into the 110-120 Hz range would be much of a problen in terms of localization, and should relieve the main drivers from excursion compression of dynamics and ultimate SPLs, which I'd think will benefit the large space.

Of course, there are still lots of possible driver combinations that haven't been discussed yet.
