John, it just came to me, I think what you are talking about with these speaker builders putting the tweeters further back has more to do with higher frequencies transitioning to the far-field further down range than freqs coming from the mids. It sounds interesting, I'll have to look into...

yeah, the doppler effect.......doesn't have anything to do with higher frequencies traveling faster....if they do..... What I was looking to eventually do is play with time correction on the horns for different listening positions. For a long room, I play the Wii game system about 5 feet...

I got it, sound waves in a line array have no special propagation characteristics. I have no problems at all. I got a new head unit for my truck with time correction it made a really big difference, just thinking of something for the house. I could build a crescent moon enclosure to take...

I have some hybrid line arrays, a line of mids matched up with a single compression horn tweeter. I know that the difference in intensity between a line source and point source gets more dramatic the further away you get. Does the rate of propagation change? The speed of sound is still the...

Sorry, should've mentioned, it's a sealed enclosure.

Do you think the hole is big enough. The braces don't go all the way to the back corner, or all the way out to the side corners, but is the hole in the middle big enough, it's about 4.5 inches in diameter, I could cut another one right behind it if necessary. Where the braces need to be for...

Not with the amount of power I can give them, even with a 15 cu.ft. box. And I really doubt my neighbors can hear me

yeah, I just looked into that, great deal, but at 4 ohm stereo with my amp it's barely a step up I feel like I am wasting too much time on this, I think I will just build a new box for the daytons and spend the money on a new center channel

right, but a XXX 18 has 34% more displacement, for ~$30 more, which I think would put me right where I want to be, for now...... pluggable ports does sound like a good idea, I guess I could use plumber's fittings on the end, like a 4" pvc pipe with a screw on cap......maybe paint it black...

it all looked good until I saw the Pnom, I guess that's thermal. I'll be driving the sub with a QSC 1450 RMX @ 4 ohms mono, might smoke it after a while. Espeacially with some of the parties around here;) I think I will go ported tuned to ~30Hz, right now those daytons are tuned to about 16...

I'm looking for an 18" supersub or maybe a couple of desent ones for my HT. The 4 12" Dayton DVC's just aren't doing it for me anymore, I need to move some more air. I have been looking at an RE 18" XXX, or maybe a couple of the SX 18's, I will probably go with one of those choices if you guys...

the enclosure in the truck is tuned to the mid/low 20's, because in a small pickup you don't have as much cabin gain as you would in most other cars, I used my little 10" Dayton DVC in a sealed enclosure .707 alignment to find the cabin gain in the truck before I built the box, the response...

I really do, I just like the headroom

well the living room is in the middle of the house, it connects the upstairs to the den, so yeah, there is alot of air there to be moved as far as normal listening levels in the truck, I'd say I keep it under 130 dBs most of the time, it'll do 150's below 30Hz on an AC mic, the best I ever...

Hey, Offering this one up for ideas, I wanna hear your thoughts, and mostly the reasoning behind your suggestion. So, I got this living room, 13 X 16 X 8, it's a little small, but huge compared to what I am used too in an automobile. Anyway, enough with the background, I got a problem...
