Subwoofers / Speakers

I'm still pretty new to the car audio world and often found myself curious about the makeup of a subwoofer and how all the parts work together. After reading conversations about cones, spiders, baskets, vent plugs, poles, etc I was thoroughly confused. I'm sure some other ppl feel/have felt the same way. Hopefully this can be as helpful to others as it has been for me... --> http://www.electronichouse.com/article/ana...f_a_driver/C201 Once you read all the verbage, click on "view slideshow" and there are a few exploded views of a subwoofer. There's still a lot more to learn, but I think this is a decent foundation to building some decent subwoofer knowledge.

how big do i need to build a box for a 'memphis pr12' 250 rms and 500 peak how much cubic ft for it also java script:add_smilie("","smid_34")

Anyone know pricing on a d2 aa havoc 15 recone?

both dual 2ohm running at 1ohm. My question, which would be better for numbers. The 9512 in a 2.75cuft box tuned to 37hertz or a 9515 in a 3cuft tuned to 37hertz. My amp is a sundown 2000d. As of right now, my suv peaks at 50hertz with now deadening.

i have 2 SA-8s in a 1.2cu ft enclosure tuned to 35hz. the guy that built me the box did really good work but the only thing he did i didnt like was only put one terminal on the box and i was thinking of inverting the subs so i could wire the subs better. any cons to inverting these subs in a box with these specs? thanks.

Selling to customer. 9/10 looks wise. 10/10 functional wise. Has 1 cube ported box too.

What is the actual amount of clean power you can send to one of the lvl 2 subs? I know the website states 300 but it even says that number is an under rated suggestion. Also how much do these subs go for? Thanks for the help.

hi, i was looking at new componots and i was looking on ebay and i can get a set of diamond audio hex s600 for 200 bucks and i am wondering if anyone has anything bad to say about them. i know people are going to say go and listen to them but no one sells diamond local where i live. so i hear they sound good but that is all i hear about them.

Anybody use/seen/heard the Lanzar opti6c comp set?? I know all Lanzar makes except the Opti line is Junk, but the Optiu amps are well built. Take a look at the Opti6c comp set and let me know what you think. They look well built. Opinions wanted Either way I hope there at least Ok, due toi the fact there already on the way Thanks, Joe

Alright so I'll give you guys some backround information. I have a 2008 Honda Fit Sport. 180 amp singer alt and xs d5100r under the hood, and 2 xs xp3000's in the hatch. 2 soundqubed 2200s strapped @ 2 ohms (each seeing 1 ohm) pushing 2 hdc315's in a 10 ish cu ft box tuned to 32hz. I don't k now how much port area there is, but it's a lot. These things get low. Sometimes I wish I tuned a little higher, but that's a whole other topic. I haven't played many test tones but on music I've been metered at 153.8 and as high as 149.9 @ 29hz. My mids and high keep up with the bass, but they're missing that "wow" factor. People that don't know anything about car audio will be blown…

I'm looking for a sub to go with my amp its a da7232 old school. Last time I used it was on a nightshade 12 v2. The setup wasn't optimal so I'm not sure on its performance. The amp is dual mono 2 ohm. Suppose to put out around 1k per channel not bridgable obviously. It will be going in the back of a suburban behind the 3rd row. So I have a decent amount of space but not unlimited. Any suggestions will be appreciated.

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

With me, with most things I learn by taking them apart and reassembling them. Thats how I got into computers. I took a few old ones apart and reassembled them. I'd kind of like to do the same thing with a sub. Of course I'm not going to tear apart my brand new SPL-12s.(still havent arrived though) I've watched the Discovery Channel video about how a subwoofer goes to together, but thats not enough for me. I see that Mach 5 sells baskets and stuff. http://cgi.ebay.com/MEMPHIS-AUDIO-MOJO-18-...1QQcmdZViewItem That is rather neat, even if it is pointless. I'd like to do something simmilar. I'd like to do a 18" subwoofer. I'd like to do it rather on a budget, so if I screw it…

My son really likes the SA8s and wants to upgrade his stereo system. Can someone help with a box design? I assume someone has done this already and has posted a box design of what they did. I've been looking but have found some crazy installs. We only want to do two subs. Ported since that is the recommended design. If going sealed does not hurt that much, then that would be an easier build. This will be our first sub project together so want to do something on the easy side. We built a pirogue so have skills. BTW, he will be powering these with a Cadence ZRS-2002 going with 2 channel, 2ohm loads. http://a248.e.akamai.net/pix.crutchfield.com/ca/learningc…

Hey guys, yes, what's minimum port area i can use for 4x RE SX 12" in 8ft^3 tuned at 33hz that will sound good? I was thinking of 54in^2 of port area (6x9 )I know it's small but i've seen some car that have small port area and sound good like Steve Meade Tahoe i remember that he had like 20ft^3 and 120in^2 of port for his 4x 18" and that's like 6in^2 for every 1ft^3, and mine is like 6.75in^2, now what do you guys think, will it be ok or bad for the SPL and Port Noise? the 4x SX 12" I'm planning to power them with 2x USAmps MD-3D, now how you guys compare this sound with 4x DD3512e power by 2x DD Audio M3? In both SPL and SQ will the SX's be close, or will the SX's win o…

I am Looking to buy Fusion PP-FR6920 and i was just wondering if anyone has dealt with fusion or knows if there a quality company?

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

Couldnt help but to ask. Box ready, amp mounted to box, 4 gauge flowing everywhere, trunk is fully Dynamated (Xtreme), CDs are burned and car is clean. I going with another 12" and maybe the 307 component set. I am not sure if I can fit that stuff on my door panels.

I'm getting 3 10 lvl 2's , ive made the box but my amp wont do all 3 @ once , on to the question.... I'll be using 2 of the subs The box i made is 3 cu @ 38hz , my qustion is because its so much bigger per sub will this be ok? what should i do/not do?

A while back I ordered a custom recone kit going from a single 2 to a dual 2 coil, and I was wondering if there would be any noteable increase in power handling, Mms, and efficiency as well as a lowering in Fs since there will be double the coil... but I think i was mostly told not enough to be note worthy. Later on I painted the cone, and suddenly I was being told I would totally mess up the drivers SQ and SPL by adding mass and making the cone stiffer (obviousely mostly by noobs and tards) Anyway, Exodus Audio's GEN II Maelstrom-X came out. Basically the only change was going from a single 4 to a dual 2 coil. The added coil length was enough that they changed the power …

would the dc level 4 still sound good in a sealed box ?

ive got a chance to pick up a blown 12'' AA avalanche, is it possible to put any sort of SI soft parts on the sub? i dont really remember is the ava is a 2.5 or a 3'' VC. thankies much.

im pretty sure that i want to go with infinity kappa speakers to match my 463.7 front speakers that sound AWESOME. right now i have a plate made for 4 4's that i have 4 proaudio speakers in it, that sound alright, but 2 of them are blown. so im probably either going with 2 693.7i kappa 6x9s, or 4 42.7i kappa 4's. im kind of leaning towards the 4's sounding better, what do you all think?

Any one think there is a better quality and sounding sub out there for the price.

a coworker has an old Eclipse TI pro 15" 1500/3000 sub that has a torn surround. its torn about 1/2 way around the diamiter of the sub, does anyone know where to get a recone OR surround for this sub?
