Oh, is this something I haven't seen? It's got to be a winner with that combo!

How's about Fullrange Assisted Tweeter Technology FATT? Somehow folks would definitely not call that fullrange anymore.
Not cheating at all its a 2-way that I posted in the full range forum

If you want some advice on FASTs I'd be happy to share what I've learned building 2. One was passive and one now active. This one I like more. I can show some measurements to if you'd like.

Personally I think FASTs are really about the best way to do a 2-way. The cross over is unobjectionable, the bass is real unlike little 6" MTs we see so many of, and generally inexpensive. The only faults are treble breakup (this one has some) and treble beaming (this one has none).

Yes, a projector screen. Acoustically transparent. I DIY'ed that to.

They are considered as part of the FR genre.

Given that no single driver is FR to get a FR system you have to have help at one end or the other. And these almost invariably have a FR driver in them... something you can enjoy all by itself.

I don't have detailed measurements on this computer, but here is the simulation I ended up on. I haven't confirmed it worked yet. Hopefully over the Christmas break I'll get a chance to do more measuring of various projects, and I can confirm the model worked.

You can see in the transfer function that I have done any eq. Only level adjustment, and filters. Filters were 4th order each. Steeper than a lot of other FASTs. I nearly targeted 2nd order, and still might try that, but wanted to kill the woofer quick and save the little tang band from to much power. Plan to really run these hard. Already have

Looking forward to your measurements.

You could also try a Allison-inspired boundary-coupled version: Mount the woofer at floor height. This should minimize adjacent-boundary effects.

No doubt. I used the same ones to build my bedroom system and they sound way better than 9.99 should sound!

I don't push mine nearly as hard as you plan to, so I just give them the full feed from the amp and they can handle the bass like a champ too. Crossed at 300, I can imagine they will take quite a beating.

In case you haven't seen what I did with the Tang Bands: http://www.youtube.com/watch?v=mGiPnsFZAqM (that's just the 2 Tang Bands... no sub - the bass will only sound as good as what you listen to the video on, of course... listen on good speakers and the bass will shock you, I think.)

I thought of that, but then they'd be at foot level, and I have a 4 and 2 year old who play a lot in that area of our house. I doubt the woofers would last more than a week. They're safe behind the screen, and quite point source this way too.

$9.99 is a hell of a steal! The plot supplied on the PE website looked extremely good. It'll be interesting to see your actual measurements. The 10-20k region looked above average for this size/cost of driver.

Screens and grills are a good idea for some adults too. I've had a few people just go and poke the drivers in a few of my builds!
