my room isn't nervous - it might be when it sees these speakers tho

The Fountek ribbons look cool but have lowish power handling for a sensitivity of 93dB/w/m. They'll not stand much power compared to the mid & bass if I give it some. The probably wont mate to the mids very well either?

Am I limited to CD with a horn?

It might be hard to find a dome tweeter that keeps up with the midrange level, though there are some. 2kHz at high power levels might be hard on the dome. It will also have a very wide dispersion pattern, contrasting with the narrowing behavior of the mid though.

Loudspeakers are the 'muscle' of an audio system, nirvana come from somewhere else. I guess some need a semi-tractor-trailer to bring home the groceries. That would make any spouse nervous, particularly when it gets parked in the front living room.

my friend got hold of a old pair of well built Cervin
I would say old enough to be vintage
15" woofer, 6" mid, small tweeter
anyway, they were ok, and played really loud and clean
just what he had dreamt of half his life

then I took out the mids and reversed phase
and we were both stunned, and couldnt believe what we heard
reluctantly I have to admit, its able to play louder than I can bare for very long, or at all for that matter, and it remains controlled, well behaved, and still sounds like pretty good hifi quality
and that with plain ordinary electronics
makes people laugh, I know
but believe it or not, it is real, and very surpricing, yes
I could hardly believe it either
mind you, I only know this one

and once again, it was only revealed only after reversing phase on the mids
food for thoughts I would say

Absolutely. Also overlooked is the role of the deep stuff in ambience. You really do miss it when it's not there- there's a spaciousness to sound with true deep bass that simply doesn't happen without the bottom octave.

I think a compression driver might be your best bet.

BMS make a few 1" ones which may be suitable. The 4544 and 4550 go down low enough for a 90x40 horn or you could use a 70 or 60x40 horn, cross at 1.9k and use the 4538.
The cheapest place for the latter is Thomann where it retails at about 60 a pop.

I'd like to hear how you get nirvana without speakers! "Nice looking amp. How does it sound?" ---- It doesn't. "Cool turntable!! how does it........?"

And yes, 'some' do need, and worst of all want, larger speakers. 'Some' may be content with a wicker basket on the front of a bicycle 'to bring home the groceries' - and good for them!

To be clear I'm only after design help. I don't require and am not soliciting validation, permission, approval or disparaging comments. There is yet not sufficient information to say these speakers will be too large, will cause sonic issues within their final resting place or create any noticeable change in spousal wellbeing.

They are going to be big. Otherwise the thread would be titled 'And now for something REALLY............normal'

Yup! sometimes things just work and it can be the simplest of changes that make the difference

And again, Yup! I find its like adding a tweeter to my 12lta - more space more air etc etc. Add a sub and again the space opens up farther, if not more!

Why not use the Econowave recipe. Crossed at around 1khz. Midbass wouldn't have to go too low. Then, add a pair of 18" woofers for the bottom octave, and you're happy
