Subwoofers / Speakers

Ok so I have one 12" ssd, with 700 watts, and im upgrading to 1200+ watts with the sundown 1200d v.2. Im not sure if I want to buy another ssd and make a new box, or just replace my existing ssd with one sub that can handle the power (and keep my existing box). I was browsing and found the hifonics olympus "olm1612," which does 1600rms bl=11, mms=204, fs=35.5. Given this sub's fs, can I still tune it to 32hz? And what does everyone think about hifonic's subs? I have always known their products, particularly their amps, to be somewhat cheap and overrated.

Going through a local shop today they had these setting in the back with a generic label on them. The lady said it had some off brand subs in there.. with no info on them any idea? I know sundown I pulled both out the coils look good.. any idea which sun down? these were the best pics I could get also it was 170 for the pair.

How many watts can a BL Fully Loaded handle without any problems?

i havent been able to find out a measurement on how deep a xcon 18 drops down into an enclosure. the enclosure would have the sub facing up, so i need to find out the length of the sub to help determine how tall the box would need to be. any help would be appreciated.

Ok guys, here's my situation . I'm running 1 18" btl with a saz-1500.... I'll be upgrading the sub amp soon. But I have stock speakers right now an they're not cutting it whatsoever. So I picked up an alpine pdx 100.4 for a good ass price. I also ordered a 4 channel 4 ga knukonceptz flex amp kit And I'm looking into a componet set or just speakers. Sizes that will fit in my car are 5-1/4 and 6-3/4. My price range is like 200-250 bucks for speakers. So I was looking into type r componets and my question is, could I run just a type r component set up front with crossovers and just two type r speakers w/o crossovers in the back? Also im wondering if i could run just 4 type …

Hello all i have ever post a similar topic on FI forum... i have two jl audio 12w6v2 sealed (1.25cu each) off a jl audio 1000/1 (1000wrms) on my mercedes clk... SQ is very amazing..... but i want LSQ ..... more db with same SQ i have ordered my new amp : a rockford fosgate T20001BD .... 2600wrms/ 1 ohm but now i must buy my subs... i want to use sealed enclosure and i haven't a big trunk... i can do a 3 cu ft sealed box... (or use my actual box 1.25cu each 12" after diplacement) so could you purpose me a couple of 12" that will be a good combo for LSQ with my new rf t20001bd ? i love to feel the bass kicking at this time i think for a couple of Q12 ... all your an…

Looking for a 10" DVC 4ohm.The box has .75 cu ft and a mounting depth of around 8". Space is very limited and I can't get a bigger box unless I want to take up the whole rear,which I don't want to do. Everybody has Alpine Type-R subs around here and I would like to not go that route.I'm sure that their are some brands I'm not aware of that you guys do. I would say around $150 for the sub. Got 600rms @ 2ohm to give it.

alright i couldnt figure out how to put pics on but who all that want pics email me at [email protected]

Would you recommend running RL-p's as spl subs?? I have two 15"s in a ported box W/ 2.5cu., and 900w rms each. The box is ported to 32hz. I was told that would be best for an LSQ set up. I was just wondering about going from LSQ to SPL.

hi, i am helping a freind install re audio xxx comps and i took off the tag that said if the red or the blue was the postive and i am wondering if anyone can tell me how to figure out which is which and or if someone has a set that might know.

i have a 2.3 cube ported box made of one layer of 3/4 mdf. it has no leaks, but i notice that the box vibrates a fair amount. would it make sense to dynamat the inside? or would this kill my sq?

I just saw the Scion XB commercial that shows what looks like lower end Lightning Audio subs attempting to "throw down." What's the deal with commercials and TV shows trying to demonstrate subs "tumping" ... and it's always less-than impressive? If they had a new or old Mag in place they'd have themselves a much better commercial IMO.

Do you guys considered the new 2011 RF P2D4 15" an overall better sub than the RE SRX 15" sub? The SRX has more linear excursion 18mm vs 12. I cannot find the Mms of either sub. The Bl of the SRX is 14 vs unknow. SPL is 87db for the SRX vs 86db. The Sd is 810 vs 894. My concern is that a sub with that much Xmax(RE) could sound louder than a sub with just 12mm but with almost 900 of Sd?? Also, the cone material of the subs: RE is Kraft pulp and the RF is Kevlar. If Kevlar is a bullet proof material is going to be a lil heavy than Kraft pulp, right? Thas why the RF Xmax is only 12mm?? It seems to me that the RF guys put a lot of technology in their new subs. The RE seems to…

hi, i have a 12" type r that needs a recone (burnt vc) and since i can get a new one for almost the same price for a recone kit i figure that i would try to do a hybrid sub with it. but here is my problem. the type r uses a 2 " diameter vc and the basket has an opening for that size vc. so while i was looking around and i could find any sub that had a 2" vc that was worth doing something like this to. so i was wondering if anybody knows any subs that uses 2" vc. and also if anybody could tell me how a type r gets a burnt vc from only 375 watts. i see that tc sounds epic have a 2" diameter vc.

I am planning on running 2 SA-8s in my mustang install (not sure if theyll be v1 or v2 yet) and I have a few enclosure questions and need a little help. Im wanting to run them in slot ported enclosures BUT they will not fire into the trunk the will fire into a space that is sealed off from the trunk but ported through the rear deck. My questions are; 1) Whats the smallest box youd reccomend for them to perform great in a daily app and still do good in a burp situation. 2) Anybody have a box design program that will map out the whole design (dimensions and all) ? They would like to use to give me a box idea.

i was setting the gains for my front stage today by using a 1khz test tone, the test tone was only for the left channel, i forgot to disconnect the speakers from my amp , so after i was done setting the gain, i smelled the smell and i was scared. I put on a lil Santana to test my newly set gains out, and it seemed that the left channel was noticably quieter than the right channel, enough where the right side, overcomes the left. the right speaker still works, gets loud, just not as loud. Is my speaker screwed?? or is there a way to get it loud again?

So i just got my wife 4 kicker cvr15's and i was calculating a box and holy crap 16cu ft!!!! At least!!! And kicker says that i should tune my box at 28hz??? Someone please help me out with a box...

I've been considering getting one of these subs but I am curious, I'm hoping that they are under rated a bit. And i know it is generally a good idea to over power the subs rather than chance clipping the amp, and I know how quality they are so I must ask will I be safe running one DCON on an Alpine MRP-M650 at 600w? I know that I can always gain down the amp but does anyone think they'd be alright at nearly full power?

How much volume is occupied by the mj-18 driver? Are the recommended box volumes the internal volume of the box, or is it the internal volume minus the drivers volume? Thanks

post your complete set up (subs, amps, box details) and the car its in. I want to see what everyone is hitting. Also if you know what kind of set up the guy is using who hit 150+ withtheone 12 let me know

Ok, i bought a us amp md3d. I am having trouble choosing what subwoofer to get. I cant go over 6-7 for the subs. Im not looking for "alot" of SQ and this for a daily driver. 1. 2 FI BL 15's 2. 1 FI BTL 15 3. 2 SSA ICON 15's 4. Mach5 slp 12( dunno anything about this) 5. 1 Incriminator Audio Death Penalty 15 6. 2 SoundSplinter RL-p 15's 7. AA Havoc Series 15 Which one would you get, and why Want one that would hit the hardest, and just put out pure bass They are going in a 07 dodge charger.

I already have one rl-i8 soundsplinter but i worried that I won't get enough out of it (not in car yet) so ive been lookin at porting it I can't go any bigger then 1 cube after port. it will get 400watts. I would just get one more and do two sealed but I can't afford another one. I have never built a ported box before, what size chamber and port do I use? can I just build one like this guy? this would fit in where I want it. at 400watts would this get plenty loud? want to hit at least 135db. http://www.caraudio.com/forum/showthread.php?t=246811 thanks all before hand

Here are the pictures. Thank you and ANY help would be greatly appreciated.

Alright, well i saw a local add up, and look what i ended up getting! BTL N2 18" Picked it up used for $380. Looked pretty good in shape, im not going to be picky because Fi subs are very few up where i live. The only real 'damage' that i saw was the surround was a little bit frayed, but not too much. Here's a picture of it. Anyways! Im stoked. Somebody local has a Soundstream TDX2000D for sale so im pretty sure ill be picking that up to power this baby. All i need is my box design and i should be murdering my Impala.
