Maybe buy a new house?

Yeah, it looks like they are using the 13W7 drivers in these subs... I have heard one of my friends 13W7 in a 3CF net box tuned to 35Hz. The sub was getting about 1200W RMS from a Memphis Belle. The setup is in a 92' Ford Taurus which you can probably hear from about 5 blocks away. It dropped the low notes like it was nobodys business... not to mention that it has 4" P-P so it looks amazing when it's moving. The thing was absolutely insane how loud and good it sounded. It was tight and controlled at the same time.

I'm thinking of building a pair of these transmission line monitors (they will cost about $500CAD)... Does anybody have any experience with these speakers and are they worth it?

Take a hammer and smash it and then get a real subwoofer.

"Thanks to om13934 I now have located my driver and I also found a suitable magnet. And Mustang, I'm sorry, did I say something funny here? Because I am sure that you havn't." So what was the point of this post then?

Not even remotely funny.

Just glue a bicycle patch on the back of the cone with some rubber cement or epoxy.

Well from what I gather... they are saying that you just put the driver on it's side and plug it in and you will be cranking out 120+db @ 20hz no problem. LOL!

http://www.adireaudio.com/Files/Dan/Parthenon/ "At the 2004 CES we'll be showing a 24" square baffle unit, with a Qts of 0.72 and an Fs of 7 Hz. Flat anechoic response to 6 Hz. And capable of over 66 liters of linear air displacement! That will generate reference level (121 dB SPL) output at 20 Hz, when sitting naked in a room - no room gain, no baffle, no box required. The first true dipole driver (not sub - no baffle, remember!) that can do reference outputs. With flat output to the single digits. How's that for a driver?" "So how far can you go? A 48" x 48" panel would be about the limit. Pretty easy to stretch the motor to 12" of peak-to-peak stroke, so that would be around 16 cubic FEET of displacement (over 450 liters of linear displacement). Now THAT would be a monster! Anyone game? I know a few famous car audio names who are already planning to use this beast, want to join that exclusive club? " 450L of stroke is like 80 Tumults...

Does anybody have any ideas on a ported Tempest that puts out good response to 25Hz? Currently, I have it in a 3CF sealed box with an Adire AVA250. I'd like a little more low end output... the current setup drops off pretty fast @ ~40-50Hz. I'd like to keep the box compact, no sonotubes though. I don't really want a 10CF box in my room. Any ideas would be great. How would a 5CF box tuned to about 22Hz sound? How much port area do I need? I also have a Shiva that I used to use in my SUV. I know the Shiva would be more optimal in the same sized small box than a Tempest but the Tempest is more efficient and drops lower.

With my experience I don't think you need a lot of power to extend low? With cabin gain you get a huge boost in the lowest octave. I got a 15" Kove Armageddon M-Series DVC-4ohm coils running on about 1/4 gain off a Crossfire BMF1000d so essentially it's getting around ~150-200W. Box is 3.25CF net tuned to 35Hz and the whole system seems to peak at around 50Hz. I've set off my neighbours car alarm from two houses down when playing a sine sweep. I also ran a Shiva in a 3CF box tuned to ~28Hz, I only had about 150W on there and the low end extension on that sub was incredible. When you have the response of the box coupled with cabin gain you have a really nice extension down to 20Hz.

Krell for $20k? I'd rather buy ten SVS subs for that price.

Here is my baby: It punches really tight and there is no boominess or distortion. 3CF sealed... lacks nuts under 30Hz cause it's 3CF sealed with only 250W RMS but I'm going to built a 9CF box with a 60 square inches of slot port. I don't know if I really need that low extension since I listen to music and I'm not a movie nerd. http://members.shaw.ca/fivelitermustang/tempest1.jpg http://members.shaw.ca/fivelitermustang/tempest2.jpg http://members.shaw.ca/fivelitermustang/tempest3.jpg

This thing sucks for the 2999.99CAD he payed for it at Best Buy. The mids are very harsh and at high volumes they really break up and are piercing. The subwoofer doesn't have any power under 40Hz. The speakers have some sort of ADAPTiQ technology that compensates the sound to the room environment but in my opinion it sounded very poor. I could put together a killer Paradigm system with a sick receiver for the price he paid for his Bose.
