So, I guess you do not measure flux if are getting. You might measure sensitivity and we might presume what when perm magnets has the same sensitivity as electromagnets then the drivers have the same magnetic flux density. Let also presume that when ...

This is a guy from Japan and he made his 4 ways GOTO drivers. What I like that he made midbass horns with smaller throat then Johan Dreyer. This Japanise guy has tall room and he made his horns to have smaller throat and to have a curve up – that is ...

Last time we wrote you thought I should focus less on tweeters and more on midbass.I am not done yet, but I have found a very nice midbass solution. Somewhat unorthodox, maybe.I have come to love police sirens! Without having A/B compared it to a pai...

Hi Romy, I ended up using a TAD 1101h 11 inch driver, 97db, 38fs, and is what I believe a stronger cone than the Goto 8 inch. The DIY mid bass horn is a 1/2 space 53hz hyperbolic horn with 5in x 5in square throat. Length is about 8'6", height of mout...

We understand that Charlus’ selection of drivers are not a selection yet but some kind of very preliminary idea of the drivers that he feels like he like. I said “he feels like he like” not accidently. I do not think Charlus, or anybody else in h...

Well, I just placed an order on the 505TT and S150 horn last week... I came across this site after placing my order and now I'm worried about the mismatch of driver/horn. It seems like I'll have to either change the horn or the back chamber. Romy, is...

Ming,
thank you very much for resonance information, it explains a lot about the SG145LD4’s suspension. Still, my primary interest was not how folks out there build 20Hz of 24Hz horns but about ability to use the SG145LD4 properly for smaller horns...

Well, whatever you do with your loudspeakers of with you whole playback system is kind of irrelevant if your drivers are not right. In my view the drivers are the very much heart of playback but in case of High-Efficiency and particularly horn-loaded...
