DD 9515 vs Fi BTL 15

Buy both, see which you like more then sell the other. Other than that, threads like these are stupid because nobody is going to exactly know which is going to be louder in your vehicle in your box, with your power, your head unit, etc....plus how will you know if one would have been better than the other if you only try one?

 
yea im not to worried about the lower bass...i want the stuff that makes the ground shake...and also i had two 13w1s in a huge *** ported box, and ive also hurd some p3s in a honda civic running off a punch 1000wat amp how is this set up going to compare to those two?? (btw i think i will get dd)
If you want something that shakes shit, then get an 18 and tune low and play songs in the lower frequency range. Bass I Love You with my RL-p made my doors cave in on me when that 15Hz tone came in, or whatever frequency it is.

 
but i only have 4.5 cubes to work with
Get a 4hp. an 18 will do in that amount of space ported. I had my RL-p 18 in 5 cubes sealed (net). got low as a a muthafvcka. i may have a video on my digi cam, gotta look for it though to make sure i didnt delete it.

 
Personal experience with the DD, i had the 9515. It got loud, thats for sure, but SQ is eh. wasn't really there, but you said you're not worried about that. I was pleased with what it did even with 500w. Put some power to that sucker and it will get loud as fawk. I have no experience with the BTL though so i can't comment on it.

 
yea but u have four lol im just hopeing this one dd with 3.5-4k of power will kill the two p3s becuase this guy brags like its the loudest thing in my town...

Umm, you will get loud off 700w. My enclosure was too large for the DD. I had it in 5.5 cubes tuned to I think it was 35 Hz. I did 141.2 with approx 700w in a trunk setup. Not to mention, I was using 1/0 welding cable for my power wire and an 8 awg wire for my ground. Battery was an HC 1400 under the hood, big 3 and was per db drag street b rules. I was up against some guy with an xB that had 2 12" JL W6 with a 1000/1 and I got 3 dB louder. I then upgraded to a better ground and put about 1.5k to it and it got quite a bit louder since I was able to turn the gain up from 1/8 to about 1/2.

Here is an actual vid of that meet, I have the green accord (though you cant really see the full vehicle nor the other car). It was funny because in the first few seconds the guy and his team were cheering thinking they were gonna get way louder than me. My amp had gone into protect for some reason at the end of the last run and i was shiitting bricks that it wont work so i started off the volume real low, as you will notice with the low numbers...then i gradually turned it up. The n00bs were bumping their system showing off for a good half hour before the meet. They had some nice flex and I thought they would get louder. Guess I was wrong //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif



Also, I upgraded to a soundstream xxx 6500, mind you this is still with a 90A stock alt, the 1400 under the hood and 1/0 power and ground wire. I would say i was doing a good 144 or 145 so probably high 130's or low 140's. Voltage was probably in the 11's as well. You will, with ease, get MUCH louder than two p3's. Shit, I used to have a 10 that would probably get louder in a sealed box. Go pwnt that sumabish.

what the ****?! you are not worried about lower bass...but yet you want to make the "ground shake" which is usually the lower bass...

do you even know what you want?

 
I'm not quite sure what he wants. but it seems he wants things to really vibrate and get loud. i guess it all depends at what frequency the objects he wants to really shake to resonate at.

my 18" rlp made my neigbors garage door vibrate from about 30 or so ft. away

 
Yeah get DD, i reccomend under 40hz for daily tuning tho.. Like I half stated, my lowend is not killer, but that is because of my Box.. give me a 40hz tone and Im in heaven!!

man u SHOULD be the loudest in ur town if he's your only competition.. me and my boy have our town and the surrounding towns shutdown.. i like the 1 15" shock factor when they hear me.. he has 4 DD 512's in 6 cubes at 35hz, and it gets stupid low in that car.. he is soon to upgrade to 6-8 512's in a wall on 3K+wrms
