[quote user="Johan Dreyer"] I had a SG370 mid apart only yesterday.I should have taken a photograph. I have also seen the inside of the tweeter. They are very similar, so I have no reason to suppose the low mid SG 505 will be much different. I'll try...

I wasn't trying to critique Bert, or even get into an in-depth critique on the Swing, more Compression Driver configurations -- vertical vs. angled, and coaxial, (and maybe other factors which affect Sound). But I'm more and more real...

There are at least three benefits of using a compression chamber in a tapped horn design.1.) When using push-pull woofers with a compression chamber second order distortion is cancelled. This effect is very audible. You must hear it to understand...

Just a quick note.I tired a JBL 3" compression driver 2490h model with original Titanium diaphragms on a 120 hz Tacrix horn. I got a response down to 200 hz. How did it sound? It sounded good clear and transparent but it lacked a little tone imho...

For those seeking some decent compression drivers that don`t cost fortune, I can suggest to try the Eighteen Sound ND1460A compression driver. It has aluminum dome and polyester suspension and 1,4 inch exit throat. Does it sound like S2 ? Probably no...

A six year ago or so when I played with different compression drivers I bought a pair of Dukane 5A540 and at that time I was not able to find any information about them. Nowadays I was pointed out that an eBay sealer “ bayleafs” actions a pair of Duk...

Hi Ronnie, There are a few things that could be causing the alien sounds you site. One, of course, could be certain frequency nodes being excited by room reflections. As long as your room is reasonably dampened, this would not...

I was listening last night a string quartet rehearsal. The play was for the most part justifiably non-so-glorious and I was thinking about my little audio things. For sure our upper MF drivers nowhere near where they need to be. There is too much...

I just wish somewhere would show up a manufacturer that would be able to produces compression drivers (or any drivers!!!) with sonic objectives…

Yesterday I spoke with a guy at a Russian audio forum who reported that he played with addressing many problems of compression driver by pumping ferrofluid in the gap. I am not a big fun of ferrofluiding generally and in case of compression drivers i...

Hi all
I have experimented a bit with rear tubes on compression drivers.
Chucked the back covers in a lathe and made a suitable hole
for the rear tube, matching the area behind the diaphragm.
Got "better" results to my ears with wool filled tub...

Hm, Yes, I kind of forgot the idea of multiple compression drivers blowing into the same throat. I never was too warm to it but I do admit that it would minimize the length of the horn. For sure the right solution would be to make compression driver ...
