I have played with the TPL150 in four and now three way systems.
I use the TPL150 from about (would have to go check the current XO settings) 1300Hz upwards.
For midrange I use the JBL 2123J, which is maybe a touch retro, but a brilliant midrange with low distortion, extra flat response and sensitivity that allows it to play in the league of the TPL150.
I went for a 10 inch mid as this is in my mind the limit at which a crossover in the 1300-1500Hz range starts hitting lobing problems. A 12 inch would in my mind be pushing the limits and likely to suffer significantly off axis.
Just to be sure, I use an 18 inch sub for the bottom end. I looked at some of the beyma bass mids, and would have been tempted if I could get them at a sane price in Australia.

Well its been a while since my last post. 139 to be exact. So I must apologise to all of you who had helped me along and posted on this thread.
I got waylaid by an alternate hobby in the form of tropical fish......1 tank became 4, totalling 400l and a 6ft custom tank was on the cards. Then Mrs JRKO said 'I'd prefer you to make the big speakers'
So here I am again in search of a 15 incher for bass duties
This driver popped onto my scope. What do you think of the 18 Sound 15W930? http://www.eighteensound.it/Portals/0/PDFs/15W930.PDF
In a 55l vented box i get -3db at 65hz which is okay by me. It seems like a really tight sounding driver......

Welcome back from the deep mate....... I've been having a 'proper time of it' last few months...... now suffering the same thing as before:
Drive units - Check
Box design - Check
Wood - Check
Some one to cut wood - Fail.
Thats a dangerous thing to say to a man who likes big speakers
Had an uncle who "got into the fish game" with tropicals. By the time he pulled out, he had 2 of the bedrooms his daughters abandoned in adulthood FULL of tanks, scores of them from 10 Gallon to 1K gallon you could barely walk between the rows of tanks, it was humid as the jungle in there too.......
Auntie told him to go back to playing with cars.....
I wish I had something to add to the driver discussion, I'm planning a lower budget HE lash-up myself, since I bought a Mini DSP and some amps to play with.....
I'm still following in the lurker zone to see what you come up with!

I am really liking the Faital Pro 15pr400. Here is latest response from K2 clone. Measurements are indoors so you are getting some room effect as well as allison effect due to driver mounting position. The Hf140 is titanium diaphragm and you can see the nasty little breakup up high. That being said, doesnt sound too bad.

Ok, you guys are just kidding around. Look at what WE did.

internal - 36" x 17
driver offset - 9"
port offset - 34"
port 3" x 3"
stuffing according to ear
PLENTY of bass in room. not flabby bass.
15pr400 is low mass cone that is efficient with low inductance and extension that rivals TD15M
this is just bass bin. horn will be housed seperately above with seamless external look

Look at the specs for Altec/GPA 515B, G as these were specifically designed to work with 1.4" exit multi-cells and the 416B as 'good enough' alternate that trades a bit of efficiency and HF BW for for a tonal balance to a lower LF corner frequency.
Odds are though that any other brands/models will be equally [or more] expensive than GPA's pricing. Note too that to get the full benefit of using a multi-cell either requires a horn loaded single 15" or large baffle loaded dual 15" drivers.

Good looking unit. I tried to use the link on that page to see about the build but I guess it's gone now. Is 2 feet deep enough to get the intended extension?
