Subwoofers / Speakers

hey guys. been a long time since i've been around. ive got a 15" mag in my max (from the first batch) and i love the way it sounds but im starting to wonder if something is wrong. the mag sits in a 3.2 ft^3 box that donn designed and gave free plans to. its being powered by a memphis mc-1000d and is seeing 1100 watts (or so im thinking, i want to get the amp bench tested). it doesnt seem like im getting the volume that i should be getting in that a ive been rivaled by several JL 15's (W3 and W0). i havent been metered yet. so there are several thing that id like to do and hopefully improve what ive got. my trunk rattles like hell because it isnt deadened but this is in …

Hello i am in the market for front stage, ive been drooling over CDT for years and finally wanna make the leap and buy some, please give your opinions, ill be using (2) sa-8's.....would you rcommend a 3 way CDT set consisting of a 6.5" / 4" / 1" on a sundown 125.2, or would you recommend i do a 2 way set which would be a 4" / 1", and a separate strong CDT 6.5" midbass, >>>point being do you think ill realy need a strong 6.5" midbass with only 8" subwoofers, or a 3 way comp set with slightly less power would be sufficient?

How do you wire a 15" IXL to a 1 ohm load? neg-neg- neg on amp and pos-pos- pos on amp?

Just about to add a system to a 1982 Cadillac ElDorado and want a hard hitting 18. Not sure to go with the RE XXX or MT or a MMATS Juggernaut?

Looking at a earthquake amp. Says its a 1000d Is it any good and would it run my p3 dual 4ohm. Amp is 50.00

i got a pm from "deafdreamz" saying to contact him to order DC subs. im just asking exactly who is this guy? not trying to start a fight it just seems odd that he would PM me out of the blue saying somehting like this.

Hey, Anyone have an IXL18.4 they are willing to part with. Thanks, Starscreamer

Hey guys! I received my Hovoc 15's 2 days (Thanks you Brian) ago and installed them yesterday. DAMN!!!! Thats all I can say lol. I had 2 Diamond Audio d3 previously and they were great. They hit pretty hard but didnt hit the lows hard enough for me. I had a Mmats 2000.1 amp powering both subs and the d3's couldnt handle it when cracked up, they started to smell like smoke after playing them hard and long. Overall they are great entry level subs, nice quality, and they hit hard. now for the havocs, out the box I knew these things was going to be a beast, and they are. After I installed them I rode around for a couple of hours just playing different songs and instantly thes…

Ive been told through another post I need to stick to Atomics enclosure reccommendation to get the most out of my APX 18 the enclosure info says sub and port displacement is already figured in their equation which is APX18-ported 6.0ft3 (40six10”long) ( 32Hz)=5000w (SB) So do I figure 6 cubes as if it was sealed then do the port to fit their req.? and I dont know how to read thier port rec. I see a 10" long port, 6" wide, but whats the 40. or is it 6" in height? Please help so I can get this box built! Or if someone wants to give me an easy out and tell me exact outside measurements (.75 MDF.) I have up to 50" in width, 25" in height and 19" depth. Thanks guys!!!

Hi, I would like to know which is the best recommended Sound Quality sub available to buy in the SSA store, prefered size 12", i would love 15" but only have a maximum of a 4cu feet for the enclosure, Thanks.

ok i have an older model mj 18 and was wondering what kind of bass response i would get if i ported it in like 3-4 cubes??

I'm trying to find out about something about subs. If I have a dual 1 ohm subs can I change them over too dual 2 ohm. I have 2 12" dual 1 ssa zcons. I'm looking for another one or two more used and if I find one that's dual 2 I would like too change them to dual 1s. If anyone's trying to sell there 12 ssa zcons hit me up

ok so the story is a guy on another forum bought a tumult, blew it and sent it in for a recone, lol never got it back and can't get any response from them. can anyone pull some strings for me to get it back?? he's sent 20 plus emails. i'll see if i can't get him to sign up.

i am gonna build a box sealed and i have just purchased a used 15" mag off a guy for a good price. i want the volume to be 2.5 cubes and have figured out the size i want to accomidate it in my chrysler 300 trunk. the measuremants will be L 24" H 18" and W 10" which comes to exactly 2.5 cubes and i want to know is the width of 10" enough since it requires a mounting depth of 8 1/8"?

i have a ab400.1 and i have dd1008a and a dd1510 that im going to recone to 15's.im going to pick up 2 more dd 1515's soon.i was wondering if my ab 400.1 is to much power for 4 dd 1515s4? im going to use this setup for daily use and comp use. this setup will be going in a 1991 ford explorer.

I found someone selling some digital designs 508s. i was wanting to know if anyone has used these and if they are any good? will they produce a good amount of bass? ps seller did not list how much he wanted for them

I having been using BBP 6 and WinISD to design a ported box for 2 Icon 12D1 and getting 2 different port lenghts. Could someone confirm which one is more accurate? My box will be made with 3/4 mdf 17 1/4 high 48 wide and 14 deep outside measurements. After sub and port displacement BBP 6 calculates this to be 4.043 cubs with a port 12.5 X 3 at 32 1/4 long tuned at 27h. WinISD says same specs with port length at 27.94. This is going in a 95 Mazda B3000 extra cab powered by a Sundown SAE 1200 for daily usage. I am fairly decent at box building but mainly just built sealed boxes. I want to try a properly designed tuned box for this new setup. Am I heading in the right direc…

Planning on putting either the 15" Fi Q I already have or getting a 15" BL in my Jeep Grand Cherokee. Both would be in a ported box to specs. I've read hundreds of user reviews and have a good idea of what both can do. The Q I've only heard in a sealed box with around 1.8 cu ft at the most. Would it honestly be worth it to go through the process of selling my Q and getting a BL? Looking for ""SQL"" and basically if the BL isn't going to be noticably louder considering the Q will play lower I'm going to stick with the Q. But idk what would you do? I definately want output while mainting decent sound, playing low etc.

Would it be possible to repost or fix the links to the images on the Mach5 Testbed site? I want to see the graphs for the test of the MJ-18 that was posted July of last year. Thanks

well i am planning on building 6 of these, i have all parts on hand, so i decided to build one, and measure it before i proceed. they will be tc2+ motors, with 6" spiders, a reproduction of the original tc1000 coil, sa8 cones, and baskets. the leads were stitched by me. the first parameters were with the coils paralleled R(e) = 1.005 ohms Fs = 38.36 hz Qts = .356 Qes = .376 Qms = 6.706 Le = .732mh mms = 112.6grams vas = .1479cu. ft. spl = 79.88 these were in series Re = 3.95 fs = 37.68hz Qts = .331 Qes = .351 Qms = 5.882 Le = 2.874mh Mms = 121.5 grams Vas = .1422cu. ft. in case any of you are used too see vas in liters those are both just a tad under 4liters. now i …

anyone ever heard an 18" brahma? Im going to get a 15 brahma reconed to an 18, with flatwind aluminum 4 layer coil. What kind of box would i be looking at? I was thinking of 7cf tuned to 32 hz, Off 1200 watts. IF anyone has any input it would be apreciated. Im wanting an 18, and i have a blown brahma. Brahma is known to be a low end monster but an 18 brahma should be awsome right? or am i wasting my money

I always see the ports extending INTO the box...what if the port was on the OUTSIDE of the box? Would this make any difference?

I have a 1994 GMC Jimmy 4-door. I am looking to replace my factory speakers. I have 4x6 speakers in the dash (not sure of mounting depth, could not find that spec. anywhere) and according to my research 6 3/4" in the rear doors (again not sure of mounting depth). This will be the first time i go with components or run the speakers off of anything but the head unit. I will be using an old rockford 2 channel amp to power the speakers, it is 100.2 (if memory serves). I need help choosing speakers to fit in the stock location. I would like to keep the cost ~$200, but i can go more if need be. I am open to all suggestions since i am a noob when it comes to this. So an…

I'm wanting to sale a sub I have laying around on Craigslist. I'm not the kind of person to screw someone over so while getting more pics a put the DMM on the coils.. That's one coil. Kinda strange on the other. First test it read 2.5 then after disconnecting the probes and I pushed on the cone. Reconnected at it shows 3.5. Not sure how to understand what's going on. My main concern is trying to sell a f'd up sub to someone. When I had it connected last it sounded decent. Didn't appear to be functioning improperly. No scraping or anything. Help me understand.
