Subwoofers / Speakers

I keep reading about deriving an Xmax number from BL. How is that done, and how acurate is it? Please enlighten me.

I wanna know when you are supposed to re cone a sub woofer ?? Is it kinda just a feel kinda thing like pushing it up down and guessing if it is to loose or to go on guessing how many hours the sub has been played.

As far as Fi subs are concerned should I run 3 10" SSDs or 2 10" Qs. Will the SSDs handle 600w rms no problem. Especially if I upgraded the SSD 3 10" Qs are a No cause of my budget I noticed that the Q is desgined to work in smaller enclosures than the SSD?

this was a hard decision but i found 2 12" 2nd gen mags for 370 shipped, it was either these or the new d2, i was wondering do these also perform well in sealed apps or ported apps, also what would be a good amp to push them, my 2500d took a crap on me and is a goner.

Hi I recently installed a pioneer deh4200ub head unit in my car. It is a nissan altima without the bose system. I currently have 2 pioneer 6x9s in the rear deck and 2 5.25 speakers in the front door and 2 tweeters on the front door as well. Their at the same level as the side mirrors if you know what I mean. Anyway the speakers in my front door seem to rattle and I am just not happy with the SQ. I would like to upgrade to something alittle nicer. I am fine with the pioneer 6x9s in the back though. I am more concerned with the front because from what Ive read here that is the most importan part as far as SQ goes. I was thinking of buying Diamond Audio D3's. They make them …

I am purchasing either of these pairs of 12s this weekend. Either set will be powered by a JBL GTO 1200.1 II amp wired to do 700 watts 4 ohms. Either set will be in a Pound That Sound Double Kerf Flared ported enclosure. I looked at many pairs of 12s and narrowed it down to these 2. I want a setup that'll get loud and sound clean. I listen to mostly rap and bass and on ocassion some rock and metal. 2 SSA dcon 12's or 2 DC Sound Labs Level 2 12's

I have some 70w rms pioneer 5-way 6x9s that sound decent but definitely not as clear as I would like. So I thought Id buy some quality 6x9s, Ive been looking around for awhile and none seem to come close to the Infinity kappa 693.9I 3-way speakers in specs. Anybody have any experience with these? Seem like a good purchase for around $100? Specifications: Power Handling (RMS): 110 W Power Handling (Peak): 330 W Frequency Response: 35Hz – 30kHz Nominal Impedance: 2 Ohm Sensitivity (2.83V @1m): 96dB Also my kenwood 6.5s are clear and sound fairly great but I doubt…

As the title says, im looking to replace my 2 10s and Im having trouble finding some that work well in my enclosure. Its a sealed dual 10 enclosure with 1.1 cu ft for each sub. Everything I have looked at has an optimum sealed enclosure of .5-.8. Anyone have some suggestions for me, price range would be around 500 for the pair. Thanks

Anyone live in michigan on here??? i need my system installed

i have two hifonics brz1200 i dont know if i should get two 12" digital designs 2500 or 3500 series i would get each sub d2 and wire each sub at 1ohm to its own amp my max box dimensions are 38W X 15H X 22D i want subs + port firing foward, no sealed

i dunno if im retarded but i didnt see it on the site? whats the mounting depth for a Rl-i 10"?

I'm looking for a 12" sq sub in the 500-600w range. I haven't been keeping up, but I seem to remember reading that RE products have gone down in quality. I know the IDQ is an all time favorite. Anything else fit the bill?

how do type r s compare to w3s

Hey guys, I'm new to these forums. Hopefully you are all enjoying your holidays. =) Anyways, I won't lie. I know little-to-nothing about car audio. I've been starting to pick some stuff up over the course of this past week, when I decided that I would like to start looking into subs/amps for my car. I own a 1998 Chevy Cavalier, and I currently have; Front Speakers - 4x6" JBL's (GTO6427) Click Rear Speakers - Energy 6x9" 3-Way's (ENC693X) Click Deck - Pioneer MP3 Deck w/ USB (DEH-P5000UB) Click I can't complain all that much about how things sound in my car, I really don't mind them. I'd just like to put some more power (specifically bass) into it now. When I first…

What is the mounting depth for the mach 5 IXL 12, and is why is the sd on this woofer smaller that most other 12" woofers

Hi, first off i would like to say that all suggestions are welcome and taken into account. I am looking for new speakers for a set up that i will be beginning very soon. For the speakers, i'm on a budget of around $300 dollars. I'm looking for speakers geared more towards rap/hip-hop, so something that can hit the lows well and has clear, crisp highs. Loudness is always a plus. I was thinking that a Sundown SAX-100.4D would be able to power most speakers that i would be considering but any suggestions on different amps would be appreciated. If you need anymore information just let me know. Thanks in advance.

Here's my 12" again I had to stop after about 20min of this i smell'd some sort of melting plastic I think it was my amp Still waiting to put my 2nd 12 in... LOOK AT MY TRUNK my sun roof did the same as my trunk... And my sunroof was closed http://www.forgottenlegacy.net/sub3.mpg

I just purchased an IA audio 18 15" but last night i was looking on craigslist and i saw a 15" memphis mojo for sale $75. I was wondering if these subs were really that great and if anyone knew how much the retailed for. I looked on memphis's site but the find a dealer link wouldnt work.

Has anyone experienced with different sealed box sizes for a MAg 12.....i have my Mag in a ported box now (2.75 cubes tuned to 35hz....and before it was in was 2.32 cuft tuned to 32hz) and i think i am going to see what the MAG will do sealed cause i would like a smaller box. I would like to know how the sound of it changes as the sealed box gets bigger and smaller.... BTW....this is right now powered by a ZR360 (530 watts) and may be down the road powered by a ZR600(~800 watts) if i ever get it fixed. So what size sealed box in the .5 to 1.5 cuft sealed box range has been best for ya'll NICK......CHIME IN!!! Scott, SC

i was thinkin about gettin 2 of these http://www.sonicelectronix.com/item_6885_Beyma+POWER+12.html in this box in my next truck http://caraudiofactory.com/20002003-ford-f...nfire-p-54.html what do you guys think of that? according to the sites ive been on it need .7 cu ft of airspace, but i just wanted to know if beyma is a decently built product, b/c the specs on that sub seem pretty impressive

Hi, I'm new to this forum, and fairly new to car audio. I happened upon this site a few days ago and saw the MAW-15's, and have read some reviews on them. I'm pretty sure I want to buy them, but I would like some input on them, first. I've been thinking about buying an IDQ15 for awhile. But, if I can pick up a sub for 1/3 of the price that sounds as good(or damn near close to it), then it's a no-brainer. I'm willing to go up to $300 for a sub. That doesn't mean, though, that I necessarily want to spend that much. I'm figuring on 500-600 wrms, and I don't want to go over 2.5 cu. ft. For the most part I'm looking for SQ. Keep in mind I'm not trying to do a competi…

I have a Toyota Tundra Regular cab with a sealed 12" Kicker 06TCVT122 400RMS at 2ohms powered by a Kicker ZX400.1 and was looking upgrading to a 15" AA Havoc in a 3.5cuft ported box @ 30hz with either a Sundown Audio 1500D or 1000D. Heres some pics of my available space LxW 60"x18" However, do to my limited space I don't think thats possible so I was also thinking of getting the 15 in a sealed box or two 12 sealed, what do you guys think?

Well I know it's not the best video, but it's all I could do. I need to change frequencies and try it again so the emblem shows up better - it's too choppy in the video I took. This is Umar's 15 running free air off of our Crown K2. Mag15Movie.MPG

What size box is recommended for 1- 10" Brahma Mk1? Its going to be a ported box.

I have a buddy that I built a box for and installed two SA-8's. He bought both of them used, one from Darren Francis, the other from a local guy. Anyway, with the subs wired in series/paralell for a 4 ohm load, one of the subs gets extremely hot after only about 3-5 minutes of play. If the sub hasn't been played and is cool, there is no scratching when pushed in, but when it's been played and gets hot, it has a little scratching noise when pushed in. Anyone know why this would be happening to only 1 sub? The other sub stays completely cool and plays fine. It is possible that one of the coils could be blown on the bad sub? I did a quick test with a DMM on the subs wired to…
