I had never heare of IA until I came across these forums. I am very interested in the DP or Warden 21 but I have a few questions. The best sub that I can buy locally is an Orion HCCA 15.2. It looks pretty bad ass but obvioussly has no where near the cone area of the 21". The last system I had was a DD9515 with a Earthquake D3. Will the DP 21" be enough to easily eclipse the DD9515 and/or the Orion? Or do I need to go up to the Warden? Current amp is a Crunch Groundpounder 3000 pro. Although it isnt my focus the orion has 4" exursion. What is the Excursion on the DP 21? I have 9 Cubes available for the box. Purpose is a rediculous daily driver/demo. Also are there options …

Does the DP 21" come with a gasket? Also what are the T/S parameters? I am seriously considering buying one, but I need that info first, thanks! Glenn

I heard that as a rule of thumb, the port area should be about half of what the cone area in the box is. Is this a correct statement? Just seems like a lot of port to me. The box will be around 20 cubes after sub/port displacement, most likely a sub up port back setup. I will be using 2 DP 21"s on 4 JL 1000/1v2's in an 03 Expedition. Wanting to tune between 30 and 32 Hz.

I got 2 21" death penalty subs. Anybody got any recommended 4th order box designs. I got 24 cu ft to work with. I was thinking of doing each sub in 2.5 to 3 sealed and 9 ported. And tuning the ported section to around 50 to 55. Let me know if you got any other ideas. I am looking for some better Spl numbers on music. Dont need it to play much under 30hz. Most stuff I listen too is around 35 or higher.

I ordered two DP 21" D2's from here and was wandering on how I should place them. I'm going to power them with the four JL 1000/1v2's that I have now, and this is all going in an 03 Ford Expedition. I want the box to go behind the second row of seats, so I have about 35" deep, 48" wide, and 32" high usable space to work with. So my question is; should I wall them, or do sub up port back? I'm looking to get as loud as possible on music. All suggestions are appreciated.

I was wondering if anyone knows if the 21s are shipping. I got a friend that wants a little bass in his ride and I think this would fit the bill. Do you guys think a sundown 3000d would push it pretty good? What kinda box am I looking at as far as cubic feet and tuning for a daily ground pounder? Thanks for the input and I will post pics on the build. Peace, Lee

I know that they rate the dp at 1500 watts but I was told that they can handle close to 2000 daily (if careful) but could a person run close to 3000 for short periods (15-20 seconds). I understand that's not recommended just wondering if its been done and what the results were.

In response to the pm: Right, I bought a 12" DP off of Justin T. and it came blown!! So I figured I'd upgrade to the 15" and if I like it, maybe buy 1-3 more for my vehicle.. Thanks, Matt

Well I just got my recones an baskets today for my soon to be DP 21's. This will be my first time doing a recone and I'm very eager to do it but a couple things I need help on. I emailed nick but I didn't know with him being at the CES deal if he would get back to me before next week. My first question is there are 6 little black plastic deals that I am not sure what I do with them? the are like hard plastic tubes. about a 1/4" long maybe shorter. My second question is what do I use for a tool to gap the voice coil when I put the recone into the basket? I have heard that some companies say to use manila envelopes but I wasn't sure how thick they should be. Thanks for…

well today started with my attendance to the MCPON (master chief petty officer of the navy) speech in the morning. but then all was said and done and i had received comfirmation that the sub was delivered (bout a week ago) and there it was in the post office sitting in a huge box. since navigating through the ship is hard enough i enlisted some help from my buddy to help me haul it up and around several decks. then after much sweating and cursing the box was finally shoved in the back seat of my faithful bucket (not the car it's going into). then i get home and ever so delicately slice the tape off. and then my jaw dropped. it wasn't soon i had a multimeter in my hand to …

I'm looking at running 4 21" Wardens for my next build, but when looking at the info provided on both lines, the only difference is the Neo motor. While I know that the NEOs can produce a stronger flux, for the soft parts listed, the triple stack on the DP will push it to the max. Also, the Warden is only 2lbs lighter than the DP , so I don't see a reason to spend the extra 400 per sub on the Warden. So what(if any) underlying features am I missing? Will I see a gain running the Wardens over the DPs and why. Again, all i'm going off of is the info provided on the site.

i havent seen any box size recommendations or tunning suggestions. anyone happen to know the optimal box size and port tuning for a ported box for these things. i plan on running 4 but if the box size is right i think i can shove 2 more in place of the front passenger side or would it be better just to make one huge box and run 6 of these and have a the port facing the drivers seat? this is going to be my first big spl car. the re xxx just isn't cutting it.
