Eelco,
Also this, Floyd Toole tells in his presentation, you can get a good idea of the speaker power if you measure what he calls " the room curve" of the speaker.
The power curve fits rather good on the room curve above 200Hz up to almost 10kHz.
If I have the more detailed information about the measurement of the speaker room curve, I will post here. Toole has written a lot of AES articles, somewhere it will be described probably.

Hello Paul,
Thank you for sharing the info. Still, the procedure you describe is indeed indirect and based on calcuation from a set of on- and off-axis SPL measurements.
I am familiar with the work of Floyd Toole and happen to own his book. The Youtube presentation, however, is new to me.
Regards,
Eelco

The Peerless seems to work nicely with the SB tweeter. I've tried the Peerless with ScanSpeak D2010 with a higher XO, but the 8" woofer needs to be crossed low.
I put a 0,33Ohm resistor in series before tweeter crossover. Treble seems better now, even shriller songs don't bother anymore. Still on the bucket list is redoing with finish with glossy lacquer to fit the subwoofers better, beeswax finish just looks dull in comparison.
Hi everyone,
You might want to look at Troel's design for a similar two way. Thanks to System7 (Steve) for pointing it out. I think this is essentially the same woofer.
Peerless HDS PPB 830860
He does use a different tweeter, and it's no longer clear if he means the ScanSpeak or Peerless version (which are almost but NOT actually identical)
If so this should fit into the smallest Dayton enclosures, about 0.3 ft3
I think he's taken kind of a middle road to baffle step compensation. It's not perfectly compensated, but it also isn't super low efficient at 85 dB.
Best,
E
