Default Stereo Integrity's new DS4 -18. 4" coil sub under $280 shipped.

What's up guys, anybody else taking a look at this new sub from stereo integrity? It's a home theater sub, but me and many others have had great success with his HT line of subs in car audio. It's more of a sealed sub. 4 cubic box sealed = f3 of 30hz. Can be ported but likes enclosures on the big side. Maybe its a good 4th order sub. I believe it's a 1500 watt rms sub, 27mm xmax 50mm xmec. Weight is around 50lbs. All for under $300...what do you guys think? just might have to pick up a couple to test out. Not much info on it....found some on avs fourum. Nick said ordering would be open tomorrow. they are intriguing....

Orders are open now. The subs have already arrived so hopefully there shouldn't be much delay.

Man i forgot my dumbass already asked Nick about these ported at 32hz in a 6' box in a car audio setup. He said that they would work but not ideal as they would come in real heavy (louder) around tuning. He did say that they would be great sealed in a car audio set up. I bet these would be efficient 4th order subs...shouldn't take a whole lot of watts to get moving some air...but I can't commit to that much space in my tahoe...it's still my family/grocerey getter lol.

this should be accurate

The final prototype is finished for the 4" coil DS4-18" subwoofer and here are the T/S parameters:

Re: 3.9 Ohms
Fs: 18.7 Hz
Qes: 0.65
Qms: 2.19
Qts: 0.50
Le: 1.52 mH
Sd: 121736.4 mm^2 (18869 in^2)
Vas: 270 L
BL: 19.9
Mms: 561.42 g
Cms: 128.2 uM/N
SPL; 86.1 dB 1W/1M
SPL: 89.1 dB 2.83V/1M
Xmax: 27 mm
Xmech: 50 mm

Price will be under $270 shipped per driver inside the lower 48 continental United States. We will offer a pre-order with a $10 discount. Pricing on this driver is aggressive so there is no room for higher discounts.

Here is a picture of the rear of the driver. The driver is sitting on its face/surround in the picture but you can see the slight motor revisions like the smaller pole vent and the addition of gap vents.
