When I model the B102 in a 48L cabinet the best I could muster is 62Hz. How is Eminence getting 54Hz? Could they be modeling the older spec driver?
I modified my 42L cab to be 48L over the weekend. I am heavily leaning in the direction of the B102 as my 10" driver for this cabinet and excited about the various tweeter options afforded by its extended response - although I'm starting with 1.6k and a compression driver. The Morel looks like a cool option too.

In another thread i did a sim for a B102 monster miniOnken. 53 litres, F10 ~40 Hz, F6 ~45 Hz

Thanks Dave, I saw that. I am unable to modify the box any further and am stuck at 48L... unless I add some kind of built in stand? Would your design work with 48L and would it extend bass lower than a simple port?
its not like one's losing a big chunk of a 12 note scale
here's the old B102 vs the "new" B102 in a Druid size pipe - I used to have graphs outdoors
with the old B102 - i may have had levels set too high as normally don't use pink noise.

B102 or BP102? I think there's a little confusion on which model we're talking about.
Emi BP102
Finally getting back.... Just to clarify... my previous post concerned the Eminence BP102, NOT the B102. Very different drivers. With the BP102 being a potential substitute for the Seas 26RE4 Dynaco A25 descendant in a new 2 way design.
Looks like my notes on past efforts with this driver are no longer accessible in my old lap top.... and the one remaining BP102 I have in stock has a bent frame... courtesy of UPS...
However, I have ordered up a new pair and they should deliver late next week. Have the right size test boxes and will re-confirm performance abilities.
Did find some of my previous 2 way crossover notes using various H.F. drivers. Want to also try a new horn load silk dome I now have. Should be interesting.

that will be fun to hear more about BP102 and horn loading the silk dome (which tweeter?) With the help of member Sonce for xover work, I'm piddling with B102 and an older APT150 tweeter. I'll work on the highpass again tonight to level the somewhat hot tweeter.
I can hardly wait John. Too bad about the damaged BP102.
In the mean time, I slapped together a pair of towers with a BP102 and a D220TI driver and Pyle waveguide (JBL clone). Hooked it up to the Zilch/JackGiff low sensitivity generic X/O. Cabinet is 12"(W) X 13"(D) X 34"(H) about 2.3 c.f. with a 4" X 7" port. It sounds better than I expected. It will need some tweaking of course.

kec - that's impressive - what's your compression driver? (- is that the 612 1 3/8" threaded waveguide?)

Driver is the Selenium D220TI and yes, the waveguide is the Pyle PH612. I also have the PRV QSC 152i clone I will try.
Boy John, you were right on about this. I just tried it with a 1.5 mh inductor in series. Here's what I get...

lookin' good & very promising - and enough lows to give some underpinning to organ, and room ambiance weight (if any in the recording)
Will you build in the waveguides or leave them mostly open kec? The speakers look seriously fun. Would closing them in would help or hinder?
There are good looking A26 kits at Solen Canada. However they replaced pictures with a graphic for some reason. I have originals I found at a yard sale, found the kits while looking for parts, some of mine are missing. My guess someone had intentions of rebuilding and never got back to them.
