Separate names with a comma.
Looks like a 2nd order electrical on the tweeter, with CD compensation and some peak EQing. 4th order electrical on the woofer. Crossover...
ExA, I hope you haven't ordered your parts yet -- you have the wrong tweeter driver, the CDX1-1440 is a titanium driver, the CDX1-1445 that I...
Here are the response curves with some further EQ (horn section only at about 20", not including port output, and no subwoofers in measurement)...
Effect of large woofer port holes on waveguide I did some tests today on some (relatively mild) response irregularities seen in my horns. I...
Here's some more shots of Tony's Synergies. He's using them variously with W-Frame woofers or Tapped Horns. [IMG] [IMG] [IMG] Here's a shot of...
--SOLD-- I hate to do this, but I just don't have room for these anymore -- (common problem for speaker builders I guess). I'm now using diy...
You might be able to get measurements close enough to avoid nulls around crossover using your mic and freeware REW. Use the crossover sections...
The measurements were made on different days, probably with different drivers. Maybe at different angles, too (some I measured on-axis, later...
Here is one of a set of 2-way Synergy horns that Tony Seaford in UK is building using baltic ply. These were calculated using my spreadsheet (see...
hard to compare the list and the schematic on a cellphone, but nothing looks out of place there. You coulx get away with a 0.47 or a 0.55mH...
do a Google or ebay search on "Gento SP99023A", they're available from places all over the world.
Re: DW-774S/DNA150 + Celestion TF0818 design/build I would, too. Dang, those look nice. See, Erich, - shelf ports!
Thanks. Still yet to be tried out, haven't had a chance to do the speakers yet.
Glad it worked out robotbunny. The clarity is from the SEOS and the drivers more than anything else. Electrostats don't have anything over those...
I've spent the weekend putting this stuff together to make active crossing over easy. Each box has one input, 4 outputs, using the 2x4 MiniDSP...
About 1200Hz for this one.
A bunch of questions have been asked. I'm always reading this on a smart phone, on which answering isn 't so easy. So, time to catch up, if I...
Re: MTG-06a-OWS Looking good. Some midbass EQ might be called for (as it is for most speakers), or maybe not, this being a surround. I like...
Here is a link to measured response and impedance files for the TD12M and the SEOS12 drivers, these are for measurement with the FRONT edge of the...
(ooops! I got the model wrong on the woofer -- it was a TD12X, not a TD12S !) Here is a link to measured response and impedance files for the...
