cracker Posted November 16, 2011 Report Share Posted November 16, 2011 (edited) Ok sorry ahead of time if i get long winded here lol. Ive been going back and forth on my next build for a damn year now and heres where im a bit stuck. I either want to do a single DC 15" on a dc 2k or a single 12" dc lvl 5 on 2 dc 2ks strapped. Id want to do the xl because i loved my old xl 15 and know what box size works and fits in my trunk. However ive been thinking the lvl 5 12 to try something dif than before. I would also have more space taking that route to build a beefier and more efficiant box but wouldnt have to cone area of the 15. So wonderin what yall think and why. What benifits other then what i already know should i consider. They are both beasts in my book and know id be happy either way but either setup is alot dif from eachother. Ok im done blabbin lol Edited November 16, 2011 by cracker Quote March 2010 SOTM winner my old buildhttp://www.stevemeadedesigns.com/board/topic/50219-dank-aka-crackers-bonne-new-v2-build-in-the-works-hahahaaaaaa/page__hl__crackers my youtube page - http://www.youtube.com/profile?user=jackiedan04#g/u my feedback - http://www.stevemeadedesigns.com/board/topic/56540-official-cracker-feedback/ i need tacos and bass to live!!!!! and will NEVER change hahaaaa TEAM NOIZE VIOLATION Link to comment Share on other sites More sharing options...
STEvil Posted November 16, 2011 Report Share Posted November 16, 2011 more cone means less excursion to for the same output and also gives the ability to go lower frequency wise before running out of excursion, assuming each uses a similar coil/motor setup that can attain the same excursion levels. 15mm xmax 15" vs 25mm xmax 12" would be a toss-up for example. Motor all depends on the design of the motor and the coil. Could be a tight gap or a loose gap, not to mention depth, back-plate design, pole design (solid vs ported), and top plate design.. Tons of things to consider. Quote MickyMcD - "Capable of making some serious trouser flapping volumes at where's-my-testicles frequencies, the Servo-Drives used to be fairly jaw dropping..." Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through. Hammerdown... 1% no links to outside websites, business related FB/YT pages allowed.

Wicks Posted November 16, 2011 Report Share Posted November 16, 2011 ^^^ Like was mentioned above, there are MANY factors that play into this but on the theoretical note: Doubling power = +3dB Doubling cone area = +3dB You're not quite doubling the cone area by going from 12" to 15" but you might be close with either solution. Again theoretically +10dB is considered to be perceived as being twice as loud. This requires increasing power by 10x... I say do what makes you happy and go with it.

cracker Posted November 16, 2011 Author Report Share Posted November 16, 2011 Ok so what im gettin is i could prob get close to the same output and or sound either choice, just depends on what space i want to give up for build or equipment? I thought about the level 5 15 too trust me lol but considerin i cant give up the whole trunk and would need more amps and batt with any size level 5 over the xl id go with the 12 there. Hmm, thinkin keeps on goin lol. I plan to start buyin equipment after the new year so theres still time to decide. Anybody ever hear the 2 dif subs in person by chance? The xl 15 and level 5 12. Im thinkin with the monster motor force of the level 5 it just has to be a mean lil shit. Ive had the level 4 15 and xl 15 to compare and damn the xl just was on another level ha Quote March 2010 SOTM winner my old buildhttp://www.stevemeadedesigns.com/board/topic/50219-dank-aka-crackers-bonne-new-v2-build-in-the-works-hahahaaaaaa/page__hl__crackers my youtube page - http://www.youtube.com/profile?user=jackiedan04#g/u my feedback - http://www.stevemeadedesigns.com/board/topic/56540-official-cracker-feedback/ i need tacos and bass to live!!!!! and will NEVER change hahaaaa TEAM NOIZE VIOLATION Link to comment Share on other sites More sharing options...

Ive had the level 4 15 and xl 15 to compare and damn the xl just was on another level ha I've owned xl 15's and a 5 12. The single level 5 got down on a 3.5k, hit lows and got loud. And that was in a less than ideal enclosure. When I had two xl 15's(on a Stetsom 7k), it was way louder, they were in an ideal enclosure though and there were two of them. The xl's do sound a little 'cleaner', don't want to say more sq, but they are smoother. XL 15 on 3.5k is my vote.

OrionStang Posted November 16, 2011 Report Share Posted November 16, 2011 Oh, if you decide on the lvl 5, get a 5k. Easier to wire up than strapping 2k's, and it can take it. Quote SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...
matt402 Posted November 16, 2011 Report Share Posted November 16, 2011 motor force > displacement IMO (& ur doubling power anyway...) Quote Link to comment Share on other sites More sharing options...
cracker Posted November 16, 2011 Author Report Share Posted November 16, 2011 Ok i hear ya orionstang. With the amp choice id do the 2ks out of price to the 7.5k and will most likely pickup one of them before making a final decision on sub. One thing i should also add is the enclosure i could build for the xl 15 would lack a few things due to size. I couldnt add 45s to the corners and not much bracing at all, single layer everywhere but the front where i could double it. With the level 5 12 id have room to double layer all around, add bracing and 45s in the corners. Id also have more room for more port. Im not out for sq i just want it to hit hard n get pretty damn low. Thanks for the responses and i will def be considering everything thats been said Quote March 2010 SOTM winner my old buildhttp://www.stevemeadedesigns.com/board/topic/50219-dank-aka-crackers-bonne-new-v2-build-in-the-works-hahahaaaaaa/page__hl__crackers my youtube page - http://www.youtube.com/profile?user=jackiedan04#g/u my feedback - http://www.stevemeadedesigns.com/board/topic/56540-official-cracker-feedback/ i need tacos and bass to live!!!!! and will NEVER change hahaaaa TEAM NOIZE VIOLATION Link to comment Share on other sites More sharing options...
