Post Subject: Throat Piece and other things...Posted by Kcct82 on: 11/21/2008

Thanks Johan, I got my SG505's and S150 horns, my throat piece is a lot longer than the one you showed above. Why can't they just sell that little screw... along with lots of other "why can't they"...

Anyway, I just reread this thread and I can make some comments... My dad and I used the BMS coaxial religiously for a few years, I can add another "BMS sucks" to this thread as if Romy hasn't said it enough. I'd also like to suggest a nice way to use BMS products for upperbass and up. Put the non coaxial version BMS (4591) on 140hz tractrix starting at 300hz and cross it to BMS coxial at 1200hz on smaller Tractrix. Now you have a pretty good looking setup along with nice graphs to show people, but unfortunately that's also the recipe for creating complete sh!t. Oh and don't forget if you plan on hanging midbass horn from above then you just saved 3 inches of vertical "tweeter" space because it's "coaxial"!

On to other things... now that we've been using the GOTO SG505 for a while, the verdict is that it does not sound good below 290hz. We found the same problem "Be" stated earlier in this thread:

"I heard a GOTO system with the GOTO 505 in the GOTO 150 Hz horn and I found it to go anemic in the lower range"

"The sound of the Goto 505 in the lower range was similiar to what you hear from a 8" woofer trying to do what a 15" can in the bass.
Although the sound was clean as free of distortions, it lacked impact and authority."
