Believe me, these speakers had no trouble with bass. They are the most accurate I've heard from a bass reflex design. The two enclosures have a different tuning frequency which was very good decision.

I really think it is worth trying to keep it 2-way. I think the 12P80Nd has good low frequency potential in the right enclosure.

From the impedance curve it looks like the fundamental resonance on the new models may be better damped. Perhaps they used a different flow resistor on the rear. The new impedance curve also lacks the peak just below 20kHz.

Otherwise it seems just cosmetic, although I remember Beyma stating some time ago that a higher power version will be announced.

that is Paul Squillos amt driver frequency curve. According to his information, it goes flat down to 500hz without a horn, and down to 200hz when hornloaeded. Almost fullrange.....
He has given me a quit reasonable price tag now..... i might try one out in the future.

Last but not least, also is introduced an improvement of Beyma’s pleated diaphragm tweeter with two different finishing, the new TPL-150S and TPL150B, offering anodized aluminium finishing with the possibility of choosing between two options, black or metal.


Sad. I was hoping they would come up with a new and improved amt, that extends down at least to 500hz.

Why not make a ribbon subwoofer like Transmission Audio. Or AMT sub horn! I doubt that Hawthorn AMT can move enough for 500Hz. Dynamics are probably very low down there.

Use the Beyma horn (or the Autotech Polish horn) for the TPL, crossover at 1.8KHz or there abouts, any lower and it sounds a bit stressed.

This sadly eliminates a 12 inch mid bass as it will beam too much up high.
How much of a real world issue is this mismatch in dispersion really? OK it is not ideal, on that we can all agree, but how much does it actually impact the sound negatively, if you could quantify it as a percentage of the overall quality of the presentation? Is it 5% or is it 35%? What does this problem actually sound like in the frequency band where it is a problem, i.e. from where the 12" woofer starts to beam till where the TPL-150H takes over, especially for listeners slightly off-center (e.g. in a home theater environment)? And how sensitive is our hearing at the relevant frequencies - perhaps we can't really tell there's a problem?

These two drivers seem to match each other rather well from a sound quality perspective, and it would be a shame if they shouldn't be used together; So is this gap in their optimal passbands a real deal breaker for the more discerning listener or is its importance completely overblown on forums like these, scaring people off from trying out, on purely academic grounds. what would otherwise be a fantastic listening experience?!

By the way, StigErik used the TPL-150H down to approximately 900 Hz to meet a 15P80Nd in his InConcert Miles, which design a lot of people seem to like and enjoy
