The midrange box should be sealed in my opinion, quite deep and with the rear 50% filled with damping material to suppress the rear wave. Filling the entire volume is not a good idea in my opinion. There should be some air between the driver and the damping material. This is because the damping material will reflect some sound, and a greater distance between the driver and the damping will reduce the level of this reflection.
Nothing 100% decided yet, but it looks like the depth will be around 45-50cm.

Instead of 2x15", I would go for single 18" per side.
15p80nd has an fs of 54hz.
18" with an fs around 30hz is a better option.
Otherwise you may end up with a very big speaker and no bass.

I already have the 15P80Nd woofers (I have the inConcert Miles speakers). Low bass is handled by three 18" subwoofers.

The equation Bl^2 / Re is often considered useful in estimating the motor strength of a driver. The Beyma 12P80Nd has the highest Bl^2 / Re among common 12" midbass candidates. This may explain why SOME ears like the 12P80Nd with its low Qts = 0.15 and middle-road Mms = 56g as a high efficiency midbass. Distortion data is also very good, especially for a 99db/watt driver.

It would be interesting to hear if anyone has done a direct comparison between the 12P80Nd and PHL or BG Neo as a midrange under the TPL-150.

Default Good comparison table

Hi Line Source

That's a very interesting idea and a useful comparison table.
I have seen a lot of your posts on various threads and I am impressed by your R&D, I like the way your mind works!

As Einstein said " Science is not what you know, its a way of thinking"

Thanks again for posting.
Cheers
Derek.
PS Is that experimental 12 inch driver in the table in production?

Anyone tried the Beyma 10B60 (not BR) in any kind of midrange config? Perhaps not a typical midrange?

As promised, here are a few pictures of the current system using a Fane Colossus 18XB, PHL 3451, and Beyma TPL-150H. Crossover points are 200 and 1511 Hz, active crosovers 24 dB/octave, and triamped.

Best regards
Peter
