Anybody ever hear of an "open air crossover"?

A speaker rep who was in a store said there speakers had this($2000 pair speakers), which elimated the hiss from their speakers. Said that only like one other manufactureer used these and they were really high end(can't remember the name he gave me).


I've never heard of such a thing, and can't find anything on them on the net. Has anyone heard of an open-air crossover before, or was he just trying to make me think his speakers were special or something??



Thnx

haven't heard of it either, but sounds like it uses the PFM protocol...



Pure F***in' Magic ;-)
Hiss in speakers? Huh? Hiss comes from sources, not speakers.
Yea that's what I thought. Figured that if it was true then I would be able find something about it on the internet.


Can't remember exactly what he said, but he said something about how the cylinder that the wire was wrapped around had gaps on the sides or something, that eliminated the hiss/noise from the speakers when the receiver was turned up real loud. So that the only way you would get any hiss/noise would be if it came from your receiver.


Anyway thanks for the replies. Just wanted to know if they were a real thing and he just explained them wrong, or if it was just all b/s.


Thnx
I would never trust that salesman's advice on anything ever again.
Air core inductors? That has more to do with power handling than hiss...
i can think of 2 things


1. no ferrite in the inductors


or


2. they do not cover the cross-over with epoxy....


take your pick.


sounds like marketing BS to me


sort of like GM saying that the cavalier has more standard HP than a Civic but leaving out the fact that the Civic is a MUCH more reliable car......

You should ask him what part of a crossover the voice coil winding is :p

Out of curiosity what was the manufacturer of these $2000 a pair speakers? What store? or Store type?
He was probably referring to air core inductors as Az surmised, and he was also most certainly very confused.
Are you sure he said hiss? Air core inductors avoids saturation of the core along with hysteris distortion. Saturation would occur when lots of current are pushed through an inductor with ferrite core.


Either way, crossovers with air core inductors are superior to ferrite core ones, but they are quite a bit more expensive due to their massive size. Did he happen to mention whether the capacitors are metallized teflon?
