Best Bass-Midrange Drivers for Alcons RB401, SA8535, ESS AMT, or Beyma's TPL-150H resp TPL150/TPL150H (for Sat-Speaker)
Most currently concepts where are this tweeters in use, select a driver, which is being able for transmission both low- and mid-bass. The whole sonic quality suffers therefore in the upper bass range. If there are subwoofer systems already present or planned at the same time, it is definitely clear to prefer transducers, which are optimized for the upper bass range but not able for transmission sub-bass. For such transducers (80-1500 Hz) I want to have an overview. My favorites, which I have heard until now are follow:

PD.121

But there are must be much more.
Thanks for advices.

The mentioned Fostex 12W150 was the wrong device. The right device is the Fostex 12W360 - go to post #129+130 about

I really like the Heil ESS AMT. It can cross over pretty low and has amazing clarity.

thank you for this advice.
who have heard this (low-) midrange drivers from eighteensound (18" sound)

all transducers looks interesting in order to design a very high efficiency satellite box, that only goes down to 55-80 Hz cut-off frequency
Thanks for advices.

I'm looking into subs below 80Hz, TPL-150/H and Beyma 12P80Nd. Forum member Angeloitacare swears by this combination. Check out his threads.
I might try the 12P80Nd and decide if I need a dedicated midrange between it and TPL, or keep it as Angelo's.

Please note: the frequency response was created by a closed box of 30 liters and free field condition. Thus this curvature isn't helpful for the decision, whether this transducer is suited or not.
Indeed, this transducer looks very interesting:

Beyma 12P80ND
the half of the costs produce this transducer maybe with still better results in case for using as satellite box without ability to reproduce frequencies below 70Hz
PD.121
Precision Devices PD.121
For use without subwoofer the mentioned Beyma driver must actually be the better choice due its resonance frequency of 45Hz and higher value of Xmax.
Glad you liked it. BTW, Angelo reports to get down to 50Hz useful output out of this driver in a sealed enclosure.
Also, note there is a "new" V2 version of this driver on Beyma's website: 12P80NdV2, which seems even smoother in the midrange. Mms/Bl is lower than V1, though, so I wonder if it sacrifices speed to get the smoother response.
In this case this threads are of interest Mark Levinson (Daniel Hertz) M1, M2):

price of EU made PA drivers seems to have sky rocketed
for that kind of price, i would consider GPA 414

The difference between the ribbons, AMT's, planars, electrostatics, etc and standard coil based drivers is all based on inductance. As those drivers do not have a coil located around a steel core (coil around the pole), they have very little inductance. They also have no inductance change with respect to excursion as standard coil drivers do.
The solution to this is to lower and linearize inductance by essentially removing the "core" from inside the voice coil, forcing it to act as an air core inductor vs and iron core. This is discussed a little here in the few pages about the Lambda 001 motor.
AE Speakers --- Superb Quality, Unforgettable Performance, Definitely.
Here are a few options others are doing with AMT's and ribbons:

Good advices.
Griffin Audio - go to

uses together with Stage Accompany's SA8535 the SEAS bass-midrange that use magnesium cone technology - this I don't like.

The old lambda technology seems to be very good.

The eighteensound 12nmb420 seems to be a good choice for the intended purpose:

also of interest could be McCauley's 6328 go to
McCauley.com : Products: Components > 6328: Overview
McCauley.com : 6328 Specifications
and PHL Audio's 3020, 3430 and 3440 - go to
PHL Audio: Products ? 10 inch in
but where are the images for frequency responses ? - I am not able to find this of both manufacturers.
Unfortuntely PHL does not publish frequency response info, which makes life more difficult for most of us. People who use them seem to swear by them, though. Tough call. I'm in the same seat as you...
Let us know if you decide to try them!
I will post responses to PHL 3450 if i receive them
But can 265mm naked even go to 2k dipole?

The German test magazine "Hobby Hifi" so as "Klang & Ton" published various measurements from some models of PHL-Audio:

Are there US magazines, which are publish similar measurements of McCauley driver devices (maybe "Voice Coil" ?)?
I don't find results - go to

maybe one of the members can post any images.

Thanks for the links! I had not come across these.
Interesting. I was thinking either 6.5" or 8". The 8", being larger, starts beaming at lower frequencies but crossing it at 1800-2000 Hz to the TPL-150H seems a good fit, while having a larger area than the 6.5" - hence more dynamics.
What doesn't look as good about the 2520 is the sagged impedance and phase curves. Do you think it's cone breakup?
"This is the only 8" pro midrange I've ever tested. Very unique driver that reminds me of the previously tested 18Sound 6ND430 in some ways. There is no copper in the motor and inductance is relatively high, however low non-linear distortion is likely obtained through motor strength and heavy saturation of the magnetic gap. Nice midrange driver though there are some serious usage limitations. Off axis of an 8" midrange droops very early and shouldn't be used above 2kHz. The driver is rated at 2mm of Xmax, though the flat foam suspension likely becomes a limit even before that 2mm is used up. For people using this mid, I'd recommend full featured excursion simulations to be sure that low end is not being over worked. That means excursion simulations done with a filter in place."
