JP is Jonathan Price to me, hes another Bass head. He seems okay to me, what happened though? I have no clue Does JP need rims again?

WCA Rusty, that already posted In this thread, owns DC Audio. FYI

Your dog is like wtf are you doing in the second pic. lol

I picked the Sundown sub as an example because Sundown is one of the few companies that gives an actual port area recommendation, not just the typical "x sq in of port area per cube". I picked the Zv.4-12 because its a roughly equivalent sized sub in terms of RMS power handling. I know it's not a perfect comparison, but 14 sq in of port area (using one 6" port for two subs) isn't anywhere near the 40 sq in Sundown recommends for their sub. This isn't the only information I'm going off of for my recommendation either. I'm also going off of my experience, and I also use box modeling software to see what kind of port velocities the OP is going to get. With a single 6" aero velocities peak at almost 80 m/sec, above 33 m/sec is when bad things start to happen and lower is better. Even if software is off by 25% (which I doubt) port velocity will still be way, WAY too high. The reason this affects daily use is primarily, you aren't getting what you pay for. If you lose 5 db to port compression, you are paying for a 4000 watt system, but only get roughly 1500 watt performance, if that even. Also there is a really good chance you will get port noise like crazy, so not only are you not getting the performance you paid for, you get some really annoying port noise you didn't want. Now the 5 db loss is just a number, I can't tell you exactly how much output is going to be lost to port compression, I wish I could. I do think that 5 db probably isn't unreasonable though. Thanks for the knowledge.

Your box is a perfect example of why "port area per cube" rules don't always work out. I've built plenty of boxes with over 20 sq in of port per cube, it all depends on what the application requires. You are going to be putting 4k watts into this box, that's going to move some air and you need to facilitate that or your output is going to suffer significantly. To put things in perspective, Sundown recommends 40 sq in of port area per sub for their Zv.4 12"s. A single 6" aero port is 28 sq in, so you have 14 sq in per sub. Does that sound like a recipe for success? I know there are other people here who are saying they've run similar setups with a single 6" aero, but here's the problem, how do you hear the output you aren't getting because your port is too small? You can't. Port compression isn't always audible, but you would sure as hell hear the difference if it wasn't there. Not sure what the Sundown subs you mentioned have to do with DC Xls he's going to use. I was quoted 9-12 areo for 12 xls from DC. I agree with you that more port might give more output, but how will the afffect daily?

Lulzzz

I got 2 DC Xl 12s on a DC 3.5k with a 6 inch flared areo port and love it.

Smoked me.... My 1ohm guesses were waaay off lulz. Congrats, Audiolamb6! A proper thanks to Steve, just for making cool videos like this, prize rewards or not.

Steve this upcoming video has me intrigued, something different for sure.

48 watts free air

Dam, that blows my mind.... I happy it's still possible to make in the car audio world. Make it, might not be right? Maybe killin it! Steve your always on the cutting edge.

Surround to frame which glue should I use, the bottle labeled CA or rubber? Usually I use CA glue but I've seen a video where the guy states DC uses rubber cement. The video is by a regular Joe not DC audio btw.

Dam, I forgot to factor in cap fatigue. I bet 10 years ago it would have made my number. Lulzzz Thanks Steve for the awesome test.

1 ohm 3244 2 ohm 2502 Total 5746

Tony D did say car off which was much diff than I thought. Not the first time I've been wrong.

I got 2 sa8v1.5 dual 4ohm, and have been wondering what the diff was between 2 AND 1.5. Thanks a ton that clears it up for me. Off topic, but I aquired these from my friend, who I had installed them under the seats of a Nissan Tittan. He didnt like the way they made the truck rattle on the low bass, so he put his flat Kenwood 8s back in. I tryed to explain to him he's missing so much bass with the Kenwoods, and to sound deaden to fix the rattles. Lulz, now the are dust catchers in my closet.

It was super late when I responsed ooops. Yes, dual 1ohms..... Me personally I would go 2 lv4 12s, but xl 15 would make you happy as well.

If you can fit 2 15s, I'd get 2 DC lv4s dual 4ohm. XL15 dual 2ohm if you go with one sub. If you can't fit 2 15s, I'd go with 2 12s lv4 dual 4ohm. Would be a debate 2 lv4 12s over 1 xl 15

BOOM DC FTW! Why the hell didn't I go to SBN...Dam

Love DC! Sweet video Rusty. Showing us how stuff is made is boss.

Where is N8 btw?

No one can answer that...... But buy the x12s and sell them. Get x15s with the 3.5k and be happy.

In my perfect world the sa15s cone area would crush the x12s? imho But in my real world, I can only fit 2 12s? 2 12s loose a ton of cone area over 2 15s. Even with the x12s having crazy xmax.

I'd snag them X12s..... Which would be louder between the two?... In a perfect world we would know.
