Bms 4555

Defo · 20th October 2009, 01:10 AM

The BMS 4555 is specced to go as low as 500hz, but the graph shows otherwise. Is it highpassed maybe?

If so, it would be great if anyone knew of an other 1,5" compression driver capable to 500hz.

Thanks.

u can use it only higher then 1kz (with 4th order filter)
500hz will blow 4555

Wouldnt that very much depend on SPL ?

My bet is 800hz/12db would be ok ?

Right now, this BMS would be my choise too
Partly because its really just a 1" driver(44mm diaphragm) with 1.5"/36mm exit
One of a kind, at least I dont know any other
I suppose I would use 20watt amp like F5, or maybe small 10watt tubeamp like SimpleSE, or newSimplePP

One idea is to have the 200 euro RCF N850 (3-inch Diaphragm, 2.0-inch Exit Throat) paying from ~700Hz to 3K with a supertweeter out of main range.
