Subwoofers / Speakers

I built my bro a box to house two CDT EF 8" subs. The box is tiny but meets the minimum recommended volume. If the bass is turned up much, whether it be by volume knob, gain, or bass knob, the subs have a high pitched electronic noise. This goes away if one sub is taken out. The only thing I can think of is that the 3" of space between the two magnets is not enough and are causing distortion. Any other possibilities? Oh yea, the subs face away from eachother so the magnets are back to back.

Waiting on you Nick

What is peoples opinions on it, and where do you find the specs on it?

So I just bought a RD 2200.1 on the pre-sale on **** and I wanted to get 2 Alpine type R 15's for it. I think I might be pushing it with these subs because the amp supposedly does 2800 rms @ 14.4 volts and does rated at 10.8 volts!!! Now I have seen some videos of 2 Type R 15's being pushed by a sundown 3K, Autotek MM 3000.1, and even an AB VFL 500.1. Do you guys think I will be o.k with these subs being pushed daily like this. I plan to tune the box to around 30 hz. Also what size box should I make?

I'm going to replace the speakers in my 98 blazer. Would it be worth it to put components in the back or just have components in the front and coaxials in the back? i plan on my this amp http://www.bestbuy.com/site/Alpine+-+Power+Pack+180W+Class+D+Bridgeable+Multichannel+Amplifier+with+High-Pass+Filter/4769803.p?id=1218524495173&skuId=4769803 and these are the components i want to buy http://www.sonicelectronix.com/item_34373_Alpine-SPS-610C.html If its not worth i plan to buy alpine type s coaxials

Well was going to buy from ssa. But i thought sundown was free shipping. Sorry.

No, you did not read that incorrectly... it says 302. Today I built the final incarnation of the SI 302 crossover, Nick and I are both very happy with the result. The set uses a 7" poly-cone midrange driver (5 7/8" cut-out) and a textile dome tweeter. Some key features: - Designed for OFF-AXIS mid installation (door install) - Extremely strong midbass (50 - 63Hz X-over is no problem at all) - High power handling for an entry level set, rating pending * They are taking ALOT more abuse than my old XR set... I destroyed an XR mid in my car. Crossovers: 15-gauge inductors (massive) Low Tolerance Audio-Grade Resistors in Attenuation network Hand-picked combination of Metal Fil…

The wife has a pair of Braxton Audio tower speakers in her work out room. These speakers are lacking in low end output and the wife asked if I could add a sub woofer to her system. She uses her system for watching movies, TV, and listening to music. I have a retired pair of 12" Shiva sonotubes that haven't been used since I built my pair of IXL-18's. Long story short, both Shiva tubes have a "clicking" sound when demands are put on them. I modeled the IXL-12 in 3.5 cu.ft., the net volume of the Shiva tube, and it looks good. IXL-12 arrives. Original Shiva sonotubes. IXL-12 and 3.5 cu. ft. tube. Removal of 12" Shiva. Comparison of Shiva and IXL-12. I remember paying $…

I'm trying to decide on the most efficient route for my summer build..I tried to come up with different variables about one of the two but no luck... Three ethos or two sp4 on 7k watts 1.sp4 Higher quality 4"vc Larger enclosure 4th order friendly Can take a lot more than rms which man's room to upgrade amp(s) with no worries Ethos More cone area Lower price tag Doesn't require large enclosures

hey guys i need some ideas i was going to run an 18in solo x in about 9cub box tuned to 35hz on a daily run and ive heard storys that the solo x cant really deal with daily pounding so i need some ideas on someother subs that will put me in the same range in output as the solo x and just a little bit better SQ then what the kicker puts out any ideas??

Opinions wanted I'm looking to build my box between 6-8 cubes I will be running around 3,000 watts RMS to the sub I want to spend between 400-600 $ I am not going for SPL at all, I want pure loudness and lows With that said, I have talked with quite a few people about this decision I need to make within the coming weeks and so far I have a few I am very interested in. 1.DC Audio Level 4 XL 18" 2.Fi Audio BTL N2 18" 3.DD Audio 9500G 18" 4.SSA ZCON 18" All I want are opinions about which I should go with while keeping all of my needs in check Any help is greatly appreciated and right now I'm leaning towards the DD! Check this out as well, sooo sick! 4 15" DDs

Here is a couple of my new subs for my new build! TC9 motor based custom "Chuck Norris" woofers! Good for about 2K a pop and they should MURDER the Lows! The others arrive tomorrow! Can't wait! Gonna run a few on the Opti @ .7ohm......Should be able to slam on these puppies ALL DAY!!! Here are some pics....vid will be up shortly that also has info on my wifes new build!

Let me start by saying that in no way, am I bashing this sub. It is god like compared to the mainstream brands I have always run in the past. My current system is 1 12" Fi BL w/ cooling on a Sundown SAZ 1500.v3. The box is right from the cut sheet on this forum, posted by ndmstang 2.4 cu. ft. @ 32 hz. I think. 1/0 ga. big 3 with Shuriken bt-80 in the trunk, stock alt. Sound deadning throughout. 2004 ford focus. I think I overshot my goals a little. During an audio show at the local shop, I hit 131.4 @ 36hz. Doing demos for people with Dubstep, I always hear about their vision blurring and noses itching. "WOW look at your car shake!" On that end of the spectrum I could …

next to the SS XxX next to the o6' Moab

This is one HOT woofer! i like the cone cover heres the rear end: upside down: nice shot of the surround: RE8 comparison. If the 700 had the bumped backplate like in the proto pix, it would have easily been beefier than the RE8:

I'm torn between an HDC3 18 and a UFO 18. Will be in 8 cubes with 1500 watts. I like the lows and sound quality doesn't matter too much for me.

So I have a 2007 Honda Accord Coupe. I am looking to get a 12'' Lethal Injection and I am looking for a sub box. I was looking on the Fisher Custom site but that is out of my price range. I was hoping that this one I found on SonicElectronix would be good. If someone could please help me out it would be much appreciated. I will ask my other question here so I don't make an extra post. Like stated above I want to get a 12'' Lethal Injection and I was wondering what would be a good amplifier to get? I was looking at a Sundown Audio but I guess the prices were just raised? That or the 1000 watt was taken off of this website? If someone could help me out it would be much ap…

Wassup everyone??? Im in the process of getting two 12" SA-12's... I want to port them.... but dont want to take up the entire trunk in my car (Looking @ a 2011 Dodge Charger). Per the info I copied below ... it says I can go with 1-1.5 cubes per sub but I just have to tune higher. Can someone tell me what the optimal size would be 1.25 or smaller per sub and the port area and tuning frequency I listen almost exclusively to rap music... Please assist! Enclosure Suggestions: 1.75 ft^3 ported tuned to 30 Hz -- F3 of 26 Hz * Tune higher and use a smaller box for more SPL oriented setup (Use 1 - 1.5 cubes) * Enclosure can be as big as 2.25 ft^3 with lower power levels 1.00 ft…

I am looking to piece together a component system which will consist of Mach 5 MLI-65 mid-ranges or AA polys between those 2 for mid bass. For tweets I am looking at Seas H1396 or Vifa D26nco5? I will probably go passive then active when I get my Sundown 100.4.... So whats the better tweeter between those two?

I have been runing 4-sundown sa-12 in my 98-explorer in a 7.6cf net box with a 110in of port on two AQ-2200 straped at 2 /// I just sold the box and subs to a buddy of mine and am thinking about runing 4-12'' Gcon with the two AQ-2200 in 10.1cf net with 4-6'' areo ports tuned to 32-33hz Are i was thinking of runing 8-10'' Dcon with the two AQ-2200 in 10.1 cf net with 4-6'' areo ports tuned to 32-33hz that would give me 113.04in of areo port with that box. So what i am asking is with the same power for the 4-12'' are the 8-10'' subs.. is cone area king what do yall think will be the best setup in my explorer.. and b4 yall ask yes i have the Electrical to run the amps…

black frame #70 SMD now all got to do is make a nice enclosure for this 18" baby .......

With my components the crossover has -3, 0 and +3 dB what do most people use? I will be right at the sets rms maybe a little over but not by much.

Hey guys..forgive my "noobness" as I am pretty new to car audio. I am checkin out some comp sets and such and am curious about a couple brands. Are Polk or Pioneer Premiums any good? I really have no clue. Thanks
