I see Troels has just updated this project with an SBA Beryllium tweeter option. Nice.
He's also done a MkII version of 'The Loudspeaker'. Completely bonkers – although slightly less bonkers than the version 1. I wish I had room for something like that ... ;-/

excellent, i was thinking of doing that myself - slim down The Loudspeaker but I was thinking about a 12” closed box bass with EQ but I like what Troels has done here. The high cost audiophool parts remain an obstacle for many.
Well, it wouldn't be useful to always design for the needs of "most people" (whatever that might be).
Because they are way out of reach both size-wise and price-wise of us mere mortals. That's not to say that I don't think it's wonderful they exist!
This design should be a floor stander since the space take by the stand is wasted. It needs
more box volume to bring up the output at box tuning, doubling the volume increases the
output by about 6 dB. Take the increased volume and make it flat to 40 Hz or tune a bit
lower with a -3dB in the mid to high 30s.
That said, it seems that he was doing a design to be similar to the JBL L100, and that seems to have driven the size.
The PSB Stratus Gold is a good comp for the size that it should be, or even a bit bigger.
At all not a substantial post!
Let's motivate:
1) freestanding box it's much-much better
2) doubling the volume brings the internal resonance at absurd levels, all reflected thru the cone ( pulp paper)
3) PSB Stratus Gold what?
Not that I like TG's design, he uses too big drivers...ok, this is one of the ultimate in size. Using a pro-driver you choose to trade efficiency for extremely low bass, but that's not a problem.
Thank you. It seems that the numbers fit the paper for the F6 ... but I was wondering if these speakers are the type that need some extra extra power
To give their best. Troel says something about it:
"Replacing my EAR-861 with my Jungson 80 watts solid state .... My Goodness, this speaker can rock! Like I've heard from The Loudspeaker driven by a Gryphon monster amp, size matters here too. High-wattage amps can do stuff, even for high-efficiency speakers ".
regards
What happens with high-power amps in combination with a speaker like Troels' is that it can go LOUD without distorting badly. Those drivers are made to do that (well, I don't know about the tweeter in Troels' design). The "average" low-efficiency "HiFi" speakers will reach their limits much earlier. Very audible distortion kicks in much ealier, and the sound collapses.
As they say: Loud is beautiful if it's clean!
I had the chance to hear this speaker with the SB Berylium dome at Troels Gravesens house yesterday. And I think it was very well balanced, and clear sounding. Bas had good control and volume enough for me. Dont expect a PA sound with these drivers, It is highend hifi sound, with the ability to sound loud !!
Only I would like to raise the speaker, on even higher stands, so that the tweeter is, at ear level/height, or else you have to sit very low, in my oppinion.
