So I have the Beyma 12p80nd in a 65l cabinet and the bare Beyma TPL-150H just sitting up top, slightly angled up. I set the crossover to 1650Hz 48 dB/octave (IIRC) and a little notch at 2k for the 12p80nd (which I have no idea is needed or not). I level matched the drivers and the bass has some EQ. Its nothing like fully refined but it already has some great qualities.and some real promise.
What about horn loaded CD to cover like 500-1800 so still it can be a 3-way? Any recommendations for CD/horn for this range?
A horn-loaded 6" or 8" would easily cover that range. Check out Limmerhorns for examples. JBL PT horns can be easily sourced in the U.S. Might be cost prohibitive to export.
Well I do have Audax PR170M0 (If I remember right) - It may have sense though it's a good driver for OB too.
Those are a popular choice for horn-loaded systems. Like you say, it would do well as a direct radiator crossed around 2khz.
Hi, first want to thanks to all writers here for a very helpful information. I want to ask for some help with my home audio project. I need a nice driver for upper bass application - 100 to 600Hz. For middle i have a Scan Speak Illuminator 12mu4731 and ordered Raal 70-10D for tweets. Read here a very nice things for Beyma 12p80. Is this driver is suitable for my case in closet box. Or any sudgestion for 10 inch - now i have a nice Vifa M25WO-08-08, but they are not in class... For subwoofer i have Volt RV3143 in ported box. Many thanks in advance for any help !

In a sealed cabinet the 12P80Nd has -F3 ~215Hz, which above your 100Hz goal.
You might get some ideas from:

Hi LineSource,
Revisiting this out of interest now that the 12P80ND and 18P80ND are no longer made which drivers would you suggest now for a three way M1 type system 18" Bass 12" mid and CD/Horn?
Thanks
DM 🙂
@ Dave123 Did you ever get around to testing the TPL-150H & the Faital 10PR410?
@darkmatter Did you end up attempting to clone the M1 speakers and if so what drivers did you decide to go with?
@LewinskiH01 What did you end up matching with the TPL-150H?

Also need to try thr TPL without the waveguide, on open baffle.
I'm using B&C 8PE21 crossed at 1.3kHz now. Went as low as 1.1kHz and as high as 1.8kHz. Tried MTM with 2 8PE21 and now using MT. Using the in open baffle. I'm happy, yet also wondering about other options. Waiting to read user impressions and measurements of the new Radian LM10n, for example.
