Subwoofers / Speakers

Hey fellas, I was wondering if anyone has some more specs for the DC Level 4 12" I was looking for: Outside Mounting Diameter (for flush mount) Driver Displacement (cu. ft) Recommended Tuning (Fb) Recommended Port Area Recommended Port Length If anyone has any of these specs available it'd be a great help. Thanks, Steven

http://cgi.ebay.com/Very-Rare-Hemp-Acousti...1QQcmdZViewItem i wonder what it can do? LOL

I measure my trunk...w/ the spare in it Alot tighter than i expected So 2 12s will fit the bill I was thinking 2 maw12's in a 4 cubic ft. box tuned to 30hz or 28hz then give them bout 400-500 watts a piece...that sound good?

In a slightl;y better enclosure than the last. Last enclosure was the fibergalss one I built which was 1.9 cu ft tuned to around 33hz using a 4" aeroport. This is a 2.1@31hz enclosure I had fisher customs makle up for me. More port area since space wasn't as critical as the GTO, plus I will have the seat down from time to time, so minimal port noise was wanted. Thje area is 31 sq inches. This setup sounds so much better than the GTO did. A lot louder as well. Most of that has to do with the 2 different vehicles though. The GTO just isn't advantageous to a sub in the trunk. The cavalier is a bit more accommodating, just a chittier car lol. Here is a few short clips. I got…

Hey Mark... hate to bug, but any word on the SPL12's? Also... can you let me know what the cutout will be for them? I figure I can make the enclosure while I'm waiting

Yep, we sent our 12" BM prototype to JimJ without ever listening to it. A lot of people would say that's a pretty stupid thing to do. But we have enough confidence in the new BM line from auditioning the 10" model that we jumped out on a limb and send him the driver. Jim has a prototype with a few things fixed vs. the 10" model - mainly the surround color - but not everything is finalized on this prototype. The only big thing left to do is to treat the dust cap for a different finish. But besides the latter, the driver Jim has will perform just like the production drivers will. Jim sent me an email yesterday letting me know he got the driver and will be testing it…

ive got a spare MJ 4 ohm laying around and i got to thinking...let throw this into the HT system. ive never messed with ht tho so im starting from the beginning. we have an Arcam reciever amp, and tuner. so my first quetion is...how do i hook everything up? is it ..sub to plate amp, and then using RCA's connect the (reciever or amp?) to the plate amp? and does the plate amp plug into the wall? secondly..what kind of box setup should i be thinking of? what would be ideal? IB or ported...this will be mostly for music and occasionally a movie or 2. probably 98% music 2% movies...if i went ported...what kind of volume and tuning should i aim for? thanks in advance

ok i got an l7 10" and thinking about sending it back and getting a different one, i got to looking at the fi q 12's and i really like them just not sure if they will get loud enough for me, and i was also lookin at the crossfire bmf's any sugegstions on what i should get??

Well, I have had a lot of back and forth with Nick today but it worked out great. He has graciously agreed to donate 10 subs to the Audio Engineering Society at Michigan Technological University for use on a project of ours. We are trying to recreate the new Elemental Designs Dodecasub, but since we are using SI drivers I know it will sound much better . I just wanted to let you guys know that Nick is an awesome guy with awesome products,

Just wondering if anyone had tried these yet? The specs seem to fit well into my plans, I've got about 450rms to play with at 4 ohms in a new project.

im keeping the door panels factory, but i think im going to throw a set of kicker SSMB8's (8" midbass) in the doors and 5.25's in the kicks, problem is, dont know what 5.25's to use (i was thinking boston pro5's) and secondly, will just those as a front stage keep up with 145+db? the other idea was to just IB a set of 8" subs. any input would be great! thanks

Hey guys need some help for a box for a Level 4 12". Im going to have 2 Lvl412's ported, giving them about 1200w each. On the DC site they recommend 1.5 cubes for Ported, and 2 cubes for SPL ported. I guess my first question is, is this measurement net or gross? Also, im kinda looking for a daily/spl setup, so would it be alright to go with 1.75 cubes per sub? And another thing i wasn't sure of, whats the recommended port tuning? for SPL or daily? Has anyone had a preference with these subs and has another recommendation? Thanks, Steven

So, a friend of mine just got two JL 12W7's...sexy lookin subs. Before he kills my system I am curious, how do these subs stand up. Are they very good subs....SPL, SQ, etc. Tryin to find out before he puts me to far to shame, lol.

hi, i am getting ready to put in me xxx comps in since i blew the tweeter in my current speakers. ( The newer type r's) i am wondering which amp would you choose if you where only runnning front speakers. Sundown Saz 100.2 and do passive with the came in the box x overs Sundown Saz 100.4 and do active ( the only thing that is turning me away is i want 200 rms @ 2ohm) Kicker Sx700.4 and do active ( see above for the turn off) Kicker sx900.4 and do active ( the only bad thing is the Price) Eclipse XA4000 and do active( 2 thing wrong not sure if the x over can run a 2 way active and the 175 watts) and if it makes any difference i am getting a pioneer 980bt for the headunit…

So I noticed Mach 5's got something in the works with the IXL 8". Was wondering if there's any updates on these?? I'm going to run a quad 8" setup and am down to my final choices of subs; DD 1508 and the RE RE8. I'll highly consider the IXL if it will rival these. ps It's great to see a Canadian company making some waves in the audio world. CHEERS FROM RED DEER!!

Current stuff is on the way out, heres what i have so far: Eclipse AVN 2210p double din cd/nav unit Alpine Type X SPX17-REF 6.5" components (07 model) DLS A5 amp (for sale, will be replaced with Arc KS900.6) Components will be bi-amped, channels 5&6 will be bridged at 1ohm for sub which should be ~550-600w. I'm leaning to a pair of new Assassin 10's ported in a console box but may get a pair of the 12's in a more conventional arrangement behind the seat. Truck is an 07 Ram reg cab so i have plenty of room, budget is $250.

I listened to this baby a little bit this weekend, power from a sundown 1500d with gains set conservatively. It was in a .7 cube sealed box. My music ranged from the lighthearted banjo strings of folk music, the hardcore double bass drums of linkin park and disturbed. I also through in some lil jon to test the low end extension. Notes: With the folk music the sub stage blended nicely with the banjo strings in the front stage. It sounded very nice on this music. It very accurately reproduced anything it was asked to. With the rock music i listened to, my favorite for daily listening personally, the bm suprised me with its output on this music. It was not muddled at all unl…

subs wont arrive for a couple days and im trying to get my enclosure done before they get here. whats the outside mounting diameter of the level 4 15s? thanks

what subs are ya working now? whats next to join the m5 line up. what will we get before xmass if any new items? have you ever thought of getting in to car amps? thanks

I went over to mark's house and got to play with his Term Lab. Magic freq was 42hz and i did a 145.7 off a Tone and 143 off music. the van is nothing but rattles though. Box is tuned to low 30's. wasnt able to run everything at full tilt because of voltage loss.

So im brand new to car audio and have been browsing this site as a guess for a while. I have decided on buying a maw-15(one) sub for my setup and am thinking about getting the rf p150, i am just making sure that they would work together nicely. If you have a better suggestion for an amp, i would be glad to hear, however im not looking to spend any more than the 211 dollars the rf amp will cost me. Thanks in advance

setup will be going in a 97 explorer ran off of a single american bass 500.1 @ 1 ohm...1250 watts per woofer. Objective....loud as chit, uncomfortable, cant breath, cant see, daily driving setup to demo at shows. Option A Sub up port back 10.62 cubes after all displacements 3 6" aeros @ 20 inches long each 30 hz tuning Option B Sub up port back 10.35 cubes after all displacements 4 6" aeros @ 20 inches long each 35 hz tuning I think option A will work very well but 30 hz tuning might miss a lot of songs apart from bass mekanik and the odd really low rap song. Any thoughts? thanks

Finally got some time to do my Wifes build for Bass Race. Equipment is 4 MJ 18s and a Massive Audio P3000.1. 18.5 cubes tuned to 30 hz. On to the pics any comments or critisim is always welcome. what Im working with. the old boxes the wood some scraps some together the port just needs the top in the van should have made it taller. This will be walled off behind the second row of seats. Bracing will be in the form of threaded rod. The only reason its in the van now is cause I dont have any room in the garage for it.

I am looking for some high quality, high efficiency, 2 ohm 6 1/2 components for my GTO. They will be running off of a US Amps USA-4300x. Sound quality is most important with output being a very very close second (hence wanting 2 ohms and high efficiency). So, any suggestions for high quality (in sound and build), high output 6 1/2's? Price cut-off is < $500

I'll be running a pair of 12W6v2 in a sealed enclosure. I'm getting Alpine PDX amps for the system because they're great amps, I can get a great deal on them, and most importantly, they're SMALL. I'm not sure whether to run a single PDX 1.1000 to the subs, or run a pair of those amps, one to each sub. So the question is, should I just be running them at 500w each or 1000w each? It's a SQ system, but I guess LSQ is more accurate. The rest of the system (6", 3", 1" in the front, no rear stage) will be run by a pair of 4.150s.
