Separate names with a comma.
The relationship (as I understand it) between cutoff and flare rate etc/high frequency output/circumference doesn't change much when there is an...
Bill, I may have offered this before...but I don't remember. Take a look at the PRV D290, it's a beast and for home use I could push it waaaaay...
JoshK, What part about the horn construction gets you flustered? I used to be that way...until I built some. I may have some tips to help you...
Scratch anything I said about the usefulness of that Dayton driver...it is NOT a closed back design even though the website says it is. I was...
Bill, Have you considered the Dayton CE70-40P-8 "full range" driver in your next design. They are cheap and are a sealed back design. I'm...
All... With the limited attachment size for this forum...I may end up having to do a word document describing my Synergy's. I have permission...
I should probably say what drivers I used in total: Tweeter: PRV D290, for the price a beast of a driver, great sound...spectacular matching...
Sorry guys...I was on a business trip. Saw the posts...didn't have time to respond. [list type=decimal] Correct on the woofer...Dayton...
Yeah, there's been a lot of progress, but not any posts. I'm on my 4'th horn design, and I can't count the number of variations I went through...
Sorry folks, not a lot of progress...we are back in a legal bind with the girls. It isn't hopeless, but it's going to be a tough one. The system...
I ended up at 2" diameter for the woofer entry ports. There *might* be some audible chuffing at <40Hz and more than 12mm excursion. But by that...
So, made a lot of progress this weekend. Made the compression driver mounting plates, discovered a clearance issue with the 2 bolt pattern, fixed...
One of the other things I experimented with was the woofer "port" diameter and size....there was audible chuffing at relatively low power levels...
I've been working on different ways to put chambers on the mids. I made a jam chuck and turned a PVC pipe for one try. Not sure if this is the...
More...this time the horn is assembled...not quite everything done though.... still need to do more work on the frustrums and add the mounting...
Some more progress pics....
Haven't posted in a bit. Here are two quick pics of the assembly jig I made to help hold the pieces. Scott
I'm still working on it. Work has gotten crazy busy and the girls have been quit demanding of time. They say girls with a background like ours...
Does it seem to be more pronounced in a paralline? Not sure...
Huh, I didn't see any substantial difference in high frequency response from centered or offset until I added the volume plug. Then it was...
