VOXATIV Ampeggio

[talaerts]

The big difference though is that the Voxativ is a point source that can be listened to up close. You need a very large room with a lot of distance between the listener and the Avantgarde for the drivers to align in time..

Well, I listened to both at around 4 metres distance. Btw this was the "small" avant garde Uno. The avant garde's sound came beautifully together at that distance. I liked both speakers very much, with still a preference for the Uno.

I have to admit, the Uno is an amazing speaker..

Just to point out, without taking anything away from them, like most back-horns the Voxative Ampeggio is not strictly speaking a pure point source either, since the terminus is not coincident with the drive unit.

At the frequencies involved the horn mouth can be effectively physically coincident, but what many forget is that the output will always be behind in time ... in a horn with good FR integration across the upper horn cutoff, the delay at cutoff is an odd number of half wavelengths, the longer the horn, the bigger the time delay.

One of the effects of this, and it drives some people crazy, some are just fine with it, is that if a fundemental occurs in the horn's bandwidth, some of the harmonics, radiated directly by the driver, will arrive before the fundemental.

True. IIRC, it's a ~9ft horn, so we're talking roughly a 7.96ms delay time. Should be OK with a fairly sharp & reasonably low acoustic XO, which it seems to have judging from the measurements.

Hello,
i heard the speaker in Hamburg and was disapointed,
if i see the measurements and compair it to the RDH20
measurements and sound, spec. the imp, i am very
happy with my construction, look:

Agreed. I was speaking more in terms of mid and high frequency cohesion. Lower bass frequencies, even in true point source designs, are so smeared and overwhelmed by the room by the time they reach your ears anyway, that a well placed, correctly designed back horn can, more often than not, sound just as cohesive..

A very interesting (and expensive) drivers. I noticed they come up with a new model called 9.87 which involves a dipole bass.
Has anyone had a chance to listen to them? I wonder what would such dipole configuration sound like with Voxativ in open baffle.

From the pictures posted the Voxativ surround has a convex roll as opposed to a concave roll for the Lowther and AER surrounds. Wonder if that makes a difference?
