Axiom Home Page Forums General Discussion Technical Questions Removing speaker grills

That wasn't always the case. Grille design has improved over the past couple of decades but back in the 1970s, there were clearly measurable and audible differences in speaker frequency response with and without the grilles. Indeed, I used to publish anechoic frrequency-response curves with and without speaker grilles in place when I was editing audio/video magazines in the early 1980s.

Alan, you aint kidding. We have some old Sansui SP-X8000 speakers with the lattice grills, those things are horrible. be better off facing the speakers twards the wall! Along with the grills, theres a nearly 1 inch lip around the front so that when the grills are in place they are flush with the cabinet, as you can imagine that really messes up the soundstage from what i can hear. But its ok because its not like they are high end speakers anyway. if all you need is something that can play music farily loudly and stuff they work great. 4 way 6 driver speaker!

Haoleb,

Hey, I remember those Sansui lattice grilles! LOL! And about 1970, JBL had a very popular L100 (L112?) 3-way "pro" monitor with a foam grille that looked like an inverted waffle iron. Available in orange or blue, if memory serves. . .

I thought it was very cool back then.

Regards,

Or the PA-style drivers that used to be in the arena here until the 80s, covered in expanded mesh - somedays I get nostalgic for that sound and set my EQ to _/\_

Speaking of PAs... if anyone's got a schematic for a Bogen C-60 Public Address amplifier, let me know? Their site has one for the C60C, but it's a much newer animal - IT has ICs!

Bren, apparently that schematic is lost in antiquity and even this outfit doesn't have it. You may have read this discussion.

I have read that discussion, John... thanks.

Spent some spare time with one of the EEs pumping a 2K tone into it and tracing through it with a scope - so far it's looking like the SCR or TRIAC that drops the voltage to 18V (the rest of the board runs off 55V from the transformer) is beefed. If I get some time tonight, going to swap it out. It's a hardly used piece of equipment, and the current arena is being demolished in a year anyway so it's not worth replacing with new. Maybe we'll just get them a megaphone.

Thanks for the attempt, though (and sorry for taking this off topic)
