usually smaller amps are more 'polite', and not for playing that loud either, so it might still work ok
Thanks tinitus. Would 8w work at home levels? its 98dB/W/m, 0.28 Qts & BL of 26.6 which is huge !!!!!!

What would you say the advantage to an 18 over a 15 other than pure size?

Some 'vintage' speaker designs I've heard were, um, sloppy. Don't know if this is poor execution but it was sort of vague and wandering. Like talking to a batty old Aunt - harmless enough but not very exciting

Lots of amps are available, both now and to make!

Maybe I'll leave the 8w for the hi freq

Fs is 37 on the PD188 as opposed to Fs of 39 on the PD154 & PD158

PD154 and PD158 both have exstremely Qts
bass will be very tight, and probably even roll off early
in worst case you might say, why is there no bass

Not too much, no. But the enclosure can be adapted to other drivers. The "Petit" uses the Altec 414, IIRC.

Not this one, not at all. Rather the opposite. Most of us are not used to a speaker with out overhang, resonances, slop, doubling. It can sound too clean for some tastes. Not the "clean bass" that comes from no fundamental/all harmonics, but clean from not having slop.

You'll find lots of photos on the interweb, take a look to see if you like its style or not. I think it's an impressive looking, as well as sounding cabinet.

Oh, I just remembered! Kevin, one of the mods, has a set of Onkens he dearly loves. I don't recall what driver he uses. We should ask.

OK so Qts of 0.2 shows quick fire punch but very lightweight bass but and Fs 0.45 has weight but maybe sloppy?

Other than Fs is there any other reason to pick an 18 over a 15?

btw, Fane Studio 5HPM could be a sweet mid driver for a 'home' studio monitor
