Re: influence of interior
I just thought of this. I wonder if cabin gain is partially caused by this phenomenon I'm thinking about and the interior 'pushes' the alignment. Maybe room gain is part standing wave modes, part 12db/oct lift and part from pushing the alignment. What do ...

Re: Horn Design
Hi Mike,Thanks for the info. I am familiar with horn theory and hornRESP, I just like to have Wayne in on complex horn designs. The only reason I'm using stereo subwoofers is to decrease standing waves and room modes... Operating more than one subwoofer s...

BTW - the bass response
Just finished with the RTA and equalizer.Had to make serious cuts from 50 to 75Hz (room modes?).Have to kick it up for the natural roll-off below 50 Hz, but its about flat to 32 Hz at the listening position with +12dB of EQ.

Re: One driver for FULL spectrum or one driver for critical portion of spectrum?
I suppose both ideas are pretty reasonable.To me, I had always dismissed the single driver idea as having too much lost on the bottom end and the top end of the response curve for my tastes. They also tended to be limited to relatively low listening leve...

Other Drivers and stuff
Hey WayneJust modelled up a few other 18" drivers on the same horn. I found that JBL 2242, Eminence Omega 18, and Eminence Magnum 18LF show the EXACT same response curve as the 18-Sound 18LW1400 response curve in my first post. I almost thought I didn't c...

Re: Constrained spatial loading
If a room's ceiling is eight feet high, then the expansion from the apex of the corner at the floor-wall-wall junction is purely conical for eight feet. At that point, another boundary is encountered - The ceiling makes the expansion become more like a p...

Cardioid subwoofer
Augsperger's cardioid looks very much like what Meyer is doing. A second driver 34" behind the first, inverted and delayed, produces the rear null. Within the cabinet, the rear driver might be assisting the front driver like a push-pull in spite of the ...

Re: Do I "need" a subwoofer?
There are folks running 6" single driver speakers that are happy with the bass, although it really isn't getting much lower than 100Hz. Then there are others that want the 20-40Hz octave EQ'ed up louder than the mids.As for me, if a system's response doe...

Re: Any good suggestions for subwoofers with full ranges?
Hi Dave,I spent some time thinking about the problem of bass below 50Hz, since that is about all you can expect rom a single driver. I came up with the following options:1. an active sub, like the Hsu, that takes output from the low powered tube amp used ...
