A few sealed designs, 3 vented designs. I counted the horn designs twice. There's still 0.

“The Lab 15 is suitable for small sealed cabinets for automotive use.” said Jerry McNutt, Design Engineer at Eminence. “Go with a medium to large sized vented cabinet or a horn loaded design for PA, sound reinforcement, or dance club applications.”

I'll admit that I've found this driver a little confusing. It has a higher fs than the original lab 12, but a similar sensitivity, and it's a bigger driver.
For PA applications (including tapped horn) the parameters are a bit strange -- Mmd is very high for a 15" driver, even one with relatively large Xmax, so efficiency is low.
It looks more like a car/home sub type driver in some ways, but its Xmax and Pe are lower than many other drivers for these uses.
Difficult to see what it's good for, there a better drivers for nearly any application I can think of...
I suppose if they dropped the resonance to 18Hz, and made it take a bigger box, we'd all be happy.
I get the impression it's one of those that you can use with a small ish box, and it will go quite low, pretty loud, and it won't be huge (think portable disco).
Otherwise, it's too high a resonance for true HT.
I suppose, moving that much air, it would stand some serious eq... Even so, there's probably drivers out there more suited to such applications.

I agree, so I am sitting on the sidelines watching, I am sure that someone has an appropriate cabinet in mind. Maybe I can learn something.

Hi iand,All..
I think of a T-TQWT use, for both Music and HT.
Thoughts in pictures..:

Hi,
FYI, A dual Lab15 driver T-TQWT: See the picture.
PS: The first picture in my posting #29 here above were simulated from the submitted TH text file in Post# 10 ( lab15_tp.txt ) and not my recommendation ( ) for a Sub to be used in any home environment due to the obviously need for FR equalization and the need for signal delaying the main speakers.

Those complaining of the absence of LAB horn plans should realize that the LAB 12 never had plans in the Eminence provided pdf file. The plans are hosted at PSW LAB, but no plans for the LAB 15" yet.

I'd want my lab15 the other way.

Home? You're joking, right? Live sound, silly. Why would anyone want a high efficiency 40hz horn for home. I wouldn't. And why on earth would anyone want a low efficiency 20hz tapped horn for live work?

I'm with Davy on this one. You can have your 18 Hz Fs "subwoofers" that take kilowatts (and need every one of them to get loud).
Give me a well-made 15 inch driver with a 35 to 40 Hz Fs, 95+ dB 1W efficiency, 18+ mm of one-way Xmax, 30+ mm of Xmech, a Vas of less than 100 L, a high BL, and reasonable Q values. I don't really see a need for more than 500 W of RMS power handling. Make it cost less than $200.
The Lab15 is so close, but not quite.
Oh - and I want a pony too.

I didn't expect I'd ever find them at Eminence. Someone has to have an idea for this thing.

I'll take a perfect power amplifier with infinite current capacity and at least 1000V output capability. I don't mind if it makes some heat, either.
I'm a thinking this is what the the LAB 15 is for...

Funny thing is that it's OLD, so maybe the driver was originally an OEM unit for this company.
