RE: To BMS 4592 ND owners re crossover caps

Hi,

I have used the BMS 4592 ND (16 Ohm) for some time now and my experience is that it is quite difficult to get it work right. I started out with the standard BMS crossover, and in my opinion it is definately not the best solution. Using this you will (depending on the horn) probably have a dip around 5kHz causing lack of presence on for intance human voices.

From Bill Woods (aka RCA-fan) I have got a clearly better crossover than the standard BMS (Thanks Bill!). Using this crossover, the presence is back. However, in my opinion there is still some harshness in the treble, which is probably inherent in the construction of the coax driver. With Bill's crossover the harshness is clearly reduced, but I doubt it can be totally eliminated by any crossover.

Now I only use the BMS mid section of the BMS 4592 ND driver and use a vintage Fostex T825 tweeter as tweeter. This has clearly reduced the harchness further. For the Fostex I also use a crossover from Bill - (thanks again!).

Bill has alowed me to upload the filters in my gallery, and I will - I just haven't come to that yet. But I can send you the schematics of the filters, if you are interested....

All the best
Peter
