if you mean in a 2way ?
lots of power for rock, but no way a violin will ever sound like a violin, like you requested

but I really think you need just a little more low end
early rolloff is not equal to tight controlled bass
I would say 'on the contrary'

Leaving power to rock aside can a 2-way not reproduce accurately? I know the one pictured below is way over what I can build but surely that cant reproduce violin etc?

I didn't get what you meant by "I really think you need just a little more low end"

thanks for sticking with me on this.

I'm still interested in your idea to buy a horn & CD and go from there

So is it the midrange, 100hz - 1000hz that is the key to perfect reproduction? With a hefty bass foundation and sensible cd&horn above

I meant to say not to be happy with 50hz, but aim a bit 'lower', like say 30-35hz
rolloff means phase shift

no, not that simple
simplificated, the 'key' is crossover phase
or more accurately, the result of what it does

It appears to me the that the 15hf510 can easily handle 50-740/1000 and can blend well with either midrange or horn. You may not get super low, but that leaves option for sub if needed. Considering your room, it may be unecessary and room gain will be more than adequate. Althought other parameters are different, it has a similar response as the Altec 416, lacking the bottom end of course.

Maybee, but i would go for 15 or 12", x-over quite a bit higher and stay 2-way.
The QW-1 has been built all over the globe and i´ve never heard any one not satisfied, although many builders have chose to x-over a lot lower than i would.

There´s many good 15" drivers around that will do just what i think You want, even more 12" which i think is the best size for a voicereproducing driver, the choice of HF driver/horn is gigantic but there´sa few new contestants that, imo, beat all competition and also are decently priced.
