Subwoofers / Speakers

Hey all. not sure if my sub is bottoming out or i have the settings done incorrectly. its an sa-8 running at 2ohm 500watts. during some songs it sounds like the sub is banging into something but if i turn the volume down it stops. box is a .75 ^3 tuned to 34hz designed by ram designs. this is my first attempt at a stereo install in over 10 years so im sure its something ive done. gain is set to half on the dial and sensitivity is at 3/4. Amp is an alpine mrd500. Any thoughts? Thanks kevin i

can anyone get me a box design for a DC audio level 4 12"? i want high bass so around 40hz, thanks in advance. pm me or email me if you dont want to post it here

I've been searching all over here and CA.com for vented box specs for my Mag. I've tried using the box calculator at subwoofertools.com and I keep coming up with ~73in^3 of port area. From reading around it seems like I should be closer to the low-mid 60s. Am I correct or should I just stick with the plans swt.com is giving me?

im thinking about getting 2 maw-15's in my trunk the box will b 6 cu ft tuned to 30hz.. any clue on wat db's i'll hit with these installed running 600 watts at 2 ohms..

that I am already wanting to try out either a new Mag, or a Rl-p, or w6. I have only had my mag for, well actually almost a year now, damn that went by fast. but I think its just from reading all the damn forums of people getting new subs it makes me want a new sub or two. well, I am definatly waiting to see the new SI sub. I love my Mag so much I am sure it will not dissapoint. I also think I am going to go back to the 3 12s configuration. I like the 15 but something about the 3 12s I miss.

ok, well i am loving the Magnum and wantto add a 2nd 12 into my car, no 15s too big. But one, i know they no longer make them and only newer ones will be coming out. Secondly they only make D2 versions. Should i wait for the new ones to come out and will they be D4 or should just buy another one of the older siler multi spoke ones and get another amp?

Looking for pricing on a single DC Sound Level 4 10" would like to review it next to my XXX, and a few other 10s so i figured i'd see what kinda pricing this sub goes for and whats the best way to go about getting one. I tryed to speak with WCA Rusty at one time about the DC brand but talks were kinda inconclusive so i thoguht i would post a thread in hopes for a response.

im working on a box for two mj18s and have a few questions what size of port do i need for a box 4.5cf tune to 30hz? would there be a big dif if the box was 4 cf instead of 4.5? ( my box is 9.36cf) any building ideals or stats or thoughts would be great thanks roddy

I was given a pair of Earthquake DBXi-12D subwoofers...I found out when i tried to put them in my friends truck, that they are in fact blown. They are supposed to be 4 ohm DVC, but as you can tell from the pics below the VC's are damaged. My question is would it be worth it to look into a recone? These are the speakers in question. Thanks in advance for any input. Luis

well i think i'm pretty much sold on SI subs now. Since my car's setup is out of commission for a bit while i redo the wiring and install, i took the Magnum over to my friends who just got a SX. I always wanted to see how the SX and Magnum compared and finally got to see. The SX is an admirable sub but i think the Magnum was a little bit much for it. While the average SPL could be considered equal, the Magnum seemed to want to be abused much more than the SX. also the SQ on the magnum never really seemed to waiver while the SX had problems on really tough bass songs like the "woofer cooker" and even Perfect Circle's Lullaby and song 11 or 12 on ....(crap don't rememb…

Alright, so I've been running a tcsounds tc10 in just a small sealed box for some time. Although this beefy lil thing sounds awesome sealed, I have been planning on doing a ported setup. Since passive radiators are the best way to "port" my sub, last week I finaly buckled down and picked up one of their matching passive radiators from their closeout sale so I could start my new enclosure. Now to my question.. For those of you who have this combo, what airspace are you working with, and how many washers are you using?? I've spoken with a tech who gave a recomendation, but I would like to hear from any of you to see what sounds best in your oppinons! Of course the soone…

The specs and design for the DC Sound Lab LFB-2k are exactly the same as the Batcap 2000 and the price is too. So my questions is, are these the same? I've been looking at The Batcap 2000 for a while, so perhaps someone may persuade me towards a DC Sound Lab.

I see people mention their subs from time to time, but has anyone tried their components? If so do you like or dislike them? What are they comparable to?

Hey well i lik eplanning ahead inabout 6 months im going to be doing major work on my 05 scion tc i currently have a 12" mag and its awsome thanks again nick... but im thinking to go insane... i was thing of doing something like this http://www.carstereo.com/images/installs/xxx9%2D01%2Ejpg in the front and something like this in the back http://www.carstereo.com/images/installs/i...%5Fsystem%2Ejpg or http://www.carstereo.com/images/installs/L...B%40B%2D3%2Ejpg sorta mixxed probably like 4-6 subs in the rear and 2 in the dash.... havent decided on amps and the fronts rears ect... but i do know what i want... and i know i have to have my car stripped and dynamated to the …

Can 't decide. I was in Sound Advise listening to the demo speakers, wanted to check out the Clarion decks. I coulda sworn the W7 was hittin with the Z6s until I realized it was just the components that were playing! Nice stuff. How do the 307s compare to this?

Hello, I just purchased two DD 1508's and am going to be putting them in my 1987 single cab toyota pick-up. I am short so it allows me to have my seat pretty far forward and I can get quite a bit of room back there. DD suggests that I put them in a ported enclosure and tune it to roughly 38 hz. Has anyone experimented with 8's and know of a better frequency to tune them at? If not I will just go with the 38. Next, I couldn't find an exact xmax on these but after reading around I discovered its about 15mm so on my port calculator it suggests I use roughly a 4" port at 20.5 inches long if I am putting it in a 1 cubic foot box. My main questions are these: will 4" pvc pipe a…

I am thinking of buying an DC level 5 18" Sub but I wanted to know if I had enough power. I have 2 Sundown 1200's so roughly 2400 watts. How would it sound with 2400 watts in a 8 C.F. Box?

~ 7.1ft^3 1200 or so watts. All it has to do is get loud for daily driving. - Steve

Should one sundown z.15 v.1 be loudder than two kicker cvr 15s? Or should i go with two 15" kicker cvxs Powered by a massive n4 nanoblock 2000rms Going in a trunk of a buick regal 2000

So I got laid off and decided to do a very budget center console sub build for my dodge ram qc. Just looking for opinions, good or bad on the following Phoenix gold rsd memphis pr jbl gt5 alpine type s Also open to suggestions in the $50 - $100/sub range. This is kind of a challenge to see what I can come up with on limited funds, not expecting any miracles. Haven't decided single or multiple sub set up yet, I am sure single would be the popular vote, though not as fun I listen to mostly hip hop, so ported is preferred, but not that big of a deal. The amp will be bought after subs are selected. Any other info needed let me know Thanks for reading Chad

I have two 10w0-4's laying around and my buddy has a 21 Chris Craft with a crap ass stock stereo. I am going to "give" him my 10w0 to use so I have something to listen to in his boat. He has a RFPunch 301x (75w x 4 at 2ohm or 40x4 at 4). Currently we are going to bridge the back 2 channels for the subs and power the fronts off the other half of the amp. Hopefully he will give me some money to spend on a sub amp shortly thereafter. JL's rec'd ae for .75cuft sealed or 1.25 ported for a car. Without cabin gain would you use a different size. Also, wondering on what you might tune it to if it were me it would be real low, but output is more of a concern here and when y…

I have modeled the enclosure and everything looks fine, but since modeling doesn

OK, so before everyone starts about how overpriced these subs are for what you get, I have a question. My friend bought one 13 W7 about 2 years ago and he's looking to sell it now...gettin married, well you know how that goes. Anyways he said if I was interested he would take $350 for it. Im pretty sure it hasn't been abused cause he usually treats his stuff good and also I know for a fact he was powering it with some type of Power Acoustik amp. Either way it probly wasnt seeing 1000 watts. Im gettin a newer car for college graduation and wanted to start with a totally different setup, replacing all the speakers in whatever it is that I get. Ive only heard one of th…

What is the loudest and boomiest sub under 1000 watts?
