I'm not sure any of this is relevant given the fact that La Scalas are so bass deficient. In fact, lack of bass response is the fly in the ointment relative to most "high efficiency" speaker systems. Unless you want to bi-amp, or you have room for a huge straight or folded horn, it won't be a full-range system.

Audio seems to be a series of compromises. With folded W bass bins you get tight and low distortion bass, but it doesn't go very deep, but that can be easily solved by adding a subwoofer. However, a 15" direct radiator in a ported box can never be made to be as low distortion and as tight sounding as horn bass. You get to choose.

You can believe that I understand the working principles of horns. Your remark wasn't about distortion, it was about accuracy. A speaker isn't accurate if bass is down 5 dB at 50 Hz. I don't think that even qualifies as hi-fi.

20 Hz, the Khorn bass bins stomp the flab and gratuitous grumbling of any bass reflex design you care to name. As for the LaScala's ... and no bass below 50 CPS... I hope your room is BIG enough to swallow a 56 foot wave if you are so adament about having your 20 HZ.

"I hope your room is BIG enough to swallow a 56 foot wave..."I don't think you understand how pressure waves work. 20 Hz is easily accomplished in the confines of a car if the drivers are capable. More to the point, it really doesn't matter if your musical tastes favor the midrange. Accuracy requires the ability to reproduce the entire range. If a speaker can't do that, it's less accurate than one that can.

I personally think there is more to accuracy than bandwidth. It may not even be the most important.
This conversation is making me scratch my head. Any direct radiator that is flat down to 20Hz is going to be 18 to 21" in diameter. That's so large that it's going to be put in it's own enclosure, and that makes it a sub-woof-er.
Maybe we should start a thread on the speaker asylum, and see how many multiway speakers we can come up with that are flat from 20Hz to 20kHz. I can't think of any, and I bet the ones that do have serious accuracy issues of their own for reasons other than bandwidth. Not that any of this matters, as I'm sure you are just being pedantic for your own amusement.

This issue isn't one of absolutes. All else being equal , a musical reproduction system that is 3 dB down at 25 Hz is inherently more accurate than one with a 3 dB point of 55 Hz. Yes, low distortion counts for something, as does SPL. However, it simply isn't meaningful to say that one or the other of these attributes is most important, and to claim a system to be more accurate as a result of that characteristic alone. That's why I responded to the statement regarding the accuracy of bass horns the way I did. As a blanket statement, it isn't true.
"Any direct radiator that is flat down to 20Hz is going to be 18 to 21" in diameter."
That's not true either.

Here, something incontrovertible, a horn loaded woofer design {or any compression driver implemented correctly} is 10 {ten} times lower in distortion than any cone or dome. If your mind cannot count that as important, your ears surely will.

The following in terms of import... The room Trumps all other considerations, followed by the speakers and I daresay the preamp before the amp I have used transformer driven volume controllers...not dead and lifeless but definitely not as realistic sounding... Overload a small room all you want... It is not realistic.and surely, not accurate.

Like 50 Hz... A known fact.

That would exclude a large number of stand mount "monitors", most Lowther designs, smaller Magneplanars some JBLs and Altec A5s & A7s.
You're a tough listener / measurer.

I suppose it wouldn't be life without compromise... I like the la scalas a lot but I can see why someone who is after deep bass response would be turned off them. I haven't got the space or budget for a more involved horn loaded system with better LF extension, and I really enjoy the sound of the la scalas. Plus, I don't like to imagine moving them again :)
