sorry if i missed it, but what r u running?Hi mate,
I just played that second track at -15db with 14db of boost at 20hz with no issues at all. Doors were rattling a good en'. Still not any where near max excursion and got 5 green lights on the BFD. Will try it a bit later but the missus is asleep (or was). :rofl:
Oh I was getting pretty scared too.
amen. I wonder just what music listeners would think if they gave a try on setups with great LLT implimentation (a step further than a huge sealed alignment).
With music, I'm usually a two channel tube amp into a two way ULTRA-high detail listener. But since adding the 21" to my AV receiver, I find I'm listening to music more in the theater, simply because there *are* depth details I'm missing with a simple 2 way-2 channel setup.
I am more and more impressed with this woofer as I use it. And I'm a difficult bugger to impress. :devil:
I'm no expert, but I can tell you that I'm wanting more bass above 30hz for music when I'm in a small 13x13 room, just because I run out of amp :bigsmile:amen.

May want to think about a bigger port.Guys,
After alot of thought today, I am going to build two 18" single ported subs in a 9 cu ft box each tuned to 15hz. The dimensions will be 24" high by 22" deep by 36" wide with a single 7" port. Power going into each sub will be 1250 watts rms into 2 ohms. WinISD is giving 110db at 15hz for one sub so two should give me 116db at 15hz and 120db at 20hz plus room gain. And it doesn't even exceed full excursion at that power going into it. I am going to put them side by side under the plasma at first but if that doesn't work then put them into each corner or along the front wall.
Good to see someone having so much success with a sealed sub.
A single 7" port 46" long per box looks decent with an airspeed of 19m/s at 11.50hz. It will have a port resonance of 147hz. An 8" port will have to be 60 inches long to maintain the 15hz tuning, and will lower the port resonance down to 111hz.May want to think about a bigger port.
