What does one purchase after owning horns?

mbl is certainly one design that can raise the bar in many regards but differently as might good horns and other more esoteric designs.

I am of the opinion that there is only so much that can be achieved with conventional dynamic box designs, though good ones can certainly still be most enjoyable. More unconventional approaches must be taken to raise the bar further in particular aspects of sound. Horns are one approach that can in terms of dynamics. mbl is another. Walsh drivers like those in the reasonably affordable and compact OHM Walsh speakers I am partial to are another.

I will not even try to respond to Unsound, but applaud his exit.

For giggles, I just read Unsound's 2nd post. Are you kidding ? Begging for a rebuttal ? The OP wants something else ? Other designs are capable of the same dynamics ? I will leave it at that !

I was at a live performance this weekend at the local symphony hall and one of the things I was taking note of was dynamics.

My thoughts at the end was that not all live (or recorded) performances are equally "dynamic". The venue size, acoustics and where you are listening from are big factors.

At this particular event, the sound quality was very good but nothing that a good home system of most any ilk would have any problem matching, at least in most peoples rooms at home.

I have been to other performances where the dynamics were absolute top notch and also then came home to find my rig to be up to the task of delivering equal results in terms of dynamics within the confines of my various listening room.

I have no horns.

I have also heard some top notch horns that absolutely sparkled and were jaw dropping in regards to dynamics and ability to generate musical involvement.

So my current assessment is that yes horns are a good way to achieve excellent dynamics but are not the only game worth playing for most in that regard.

Mapman, obviously any duplex or coaxial horn speaker is the exception to what you say as are single driver horn speakers.

The Feastrex 5" field coil driver has great promise, but even there I don't expect that they can ever get great bass out of it.
