Separate names with a comma.
The lowpass section to the midranges is done that way to increase delay to the midrange, to better bring it into time alignment with the tweeter...
Hi JaCro/James, I'd be a little worried about the perforated metal vibrating and resonating with all the pressure from the woofers. But it might...
Hi Maxphan, Yeah, it was the same placement as before. But only because the ports had been made for a three-way version and I only used those as...
probably the ewave design won't be far off. I remember Erich said the horn depth of SEOS and the ewave JBL horn are very close.
Instead of a trim ring you could instead use a router and circle jig to cut a moat in the outside of the horn wall for the surround to clear....
Scott, FWIW the ripple on mine has never been as much as modeled. I think the losses and/or asymmetries smootb out the peaks. Have you looked at...
I put a D360 in with 4 NS6es, same port locations. It can work (though not linear phase - not enough overlap. I doubt that really matters though).
Right, the woofers near the screen help the bass a little. Though that could easily handled by EQ (Audessey, etc). If you have room, the Big,...
Very cool! Sounds like what youre making will resemble an SH50? Have you thought of mounting them against the walls to make them effectively...

oops. Yeah, that should be 266-556.
Hi Scott, I'm not sure what that angle is called. It's the angle on the edge of the board (the edge there isn't perpendicular to the large plane,...
Alex - are you building a horn this season? My wife and I plan to retire to Portland in a few years, nice place.
mtg90-- I haven't measured the on-axis/off-axis differences yet. But in an unfortunate way, they're a little worse- the little 2" mid driver...
The HF CD is mounted to a plate made from thin plywood glued to the horn throat. The midranges and woofers are mounted with short woodscrews over...
TB46, The formulas used are from Keele, see his "What's so Sacred about Exponential Horns" paper. You can adjust ratw to make it smaller if you...
nice one, Tux
Sorry I don't know much about that company, but the first set of graphs there already makes me wary. They show a 'regular' speaker with all...
you got it. There weren't a lot of vans in the olden days when classy names were around. I was trying to find how to say white van In Latin...
