Subwoofers / Speakers

What sized ported box do you recommend for the mj-18? I want to use 4 of them. I have an Astro so I have plenty of room. Thanks.

So, I was going to upgrade my system soon. And I am going to get two 15" subs. So here are some of the ones I was looking at that were in my immediate price range. Cerwin Vega VMAX 15.4 Fi SSD15 Rockford Fosgate P3D415 Alpine SWR-1522D So out of those, which set would you all recommend the most? If you know of any other ones please feel free to inform me about them. Thanks ~MadroX

just kidding. I am just anxious to see SI back up and running. Ever since SI was robbed I have turned alot of friends onto the Mag. They keep asking me when will more be for sale. Its amazing how people will talk crap about your sub cause its not down at the local sound shop then gauk at it after hearing it and try to buy it from you. Any recent info on how things are coming for SI? sure hope Nick and them don't abandon the SI 8" midbass. I have been holding out.

Current set up is as follows: 2 AA Poly mids mounted in each door. WELL deadened. 80-2500Hz Vifa XT25 mounted about 12" above mids. HP around 2800Hz Xovers done via a Helix amp. I'm very happy with how it sounds, but you know how the upgrade bug is. I'm considering going 3 way with a dedicated midbass to replace one of the poly mids. Something like this: Peerless SLS 8" 60-250Hz Poly mid 250-2500Hz Vifa 2800+ I would also need to get an electronic xover and am not sure what yet as I haven't researched them. I'm looking for more punch/kick up front, mostly for 80's rock/metal, so lots of kick drums. But I don't want to lose the incredible midrange output for guitars, etc…

so, im trading in my tahoe and took out the 2 15 BLs. i loved how it hit with rap music and somewhat liked the performance with electro/house/etc. so i cant use these anymore so im going to sell them to a friend. now im getting a car and was wondering what would be a decent set up? i was thinkin 2 10s or 2 12s Q sealed for space/volume reasons. i got 2 kickers 1000.1 topoewr each sub, should i get something else instead? i'll have to look at the car today and figure out my available work space after i do some homework(actual school homework, lawlz) Im not sure yet lols just hopin for some ideas i guess. i dont want the car to rattle, but i dont have alot of money atm to i…

I have 4 6.5 SXMP mid range speakers that I want to run together in my Tundra. I have come across a Sundown SAE-600D mono amp for a great price. Will this amp be suitable for these 6.5s? Thanks.

Well, I finally blew this little sucker. Tough to believe, but this little $15 dollar driver actually sounded good and performed rather well in a minute .33cubes. I was intrigued by the design so I decided to tear it apart. Have a look. Motor removed. Can you believe this tiny thing is the driving force??!! Coil. It's a little burnt, but not much. It appears as if the winding has broken, but I can't tell for sure. All done.

My buddy has a 13w7 and burnt up a friggin voice coil on it with only like 1100 watts, how is this possible?? It wasnt overpowered, it was professionally installed in a ported box, and plus i thought it was supposted to be VERY difficult to do that to a w7??

i have one dual voice coil 4 ohm sub. i wired it to 2 ohm. i checked the resistance with a DMM and the read out i got was 2.5 ohms. is this normal? also when setting my gain should i use the formula 500 watts x 2 ohm = sqrt (1000) = 31.62 or should i do 500 watts x 2.5 ohm???

* I've used infinity reference coaxils running off of an eclipse EA4100 (75x4), 2 kicker CVR 12' subs running off of a sundown SAE 1200' * I'd like to spend about $300 used/ebay/craigslist/classifieds for the components (I have more money set aside for sundown amps to run them) * car = Mazda Protege 2002 Sedan * Never heard any other products, I don't seem to have any good car audio shops near me... * Musical preferences = Rock, screamo, metal, things like senses fail, a day to remember, things with a lot of fast drums/bass guitar. * Its a daily system, I'd like to be able to FEEL the vibrations resonate in my chest, I don't care how loud the bass gets as long as I can FE…

Sorry didn't see the Mach 5 forum. I put this in the speaker forum as well. Anyone tried these sealed? I don't want to take up a significant portion of the back of my Tahoe since I have baby things. So has anyone tried these sealed around the 2.5 to 3 cubes per sub range. Just so you know they won't have a ton of power on them. Just the sub channel on my Kicker ZX700.5? I'm trying to get something that is a louder and lower the JL12W3's in there now. I'm moving those to my Camaro.

how do people take the sub out of the basket without wruening the subwoofer i seen it in one of steve meades builds and i have seen it in others

I have purchased a Mag D2 15 and am trying to find the specs on it so I can build a box for it while I wait on Fedex. I'm sure it's been posted a million times somewhere and I apologize if it has. I am finding a ton of info on the new Mags though Can anyone point me in the right direction or hook me up with some specs please? Need to know what size ported box they like, Cutout diameter, Mounting Depth, and anything else that would be useful to me. If I can't find info I was just gonna do 4 cubes at 33hz. Thats a pretty standard number for a 15. Someone help me out please. Wayne This is the model I have coming. Thanks again! I can't wait to have it tearing my new truck up…

Is it just me or is Nick one sexy mofo?

For everyone buying our new etreme subs, we had 3M develope a new adhesive that will handle 28 degrees more temp than the normal adhesives used by other companies. We actually spend almost $400.00 dollars a gallon for this glue. In the gift product box there is a break in period warning that states 40 hours. This is correct for the moving parts to relax but the recomended break in should be initally done in the first hour of the install. Play the syetem at 2/3 volume for 30 minutes to heat coil. shut system off and allow to cool completely. At this point the adhesive has been activated and set. the moving parts will still take some time but you can hammer the subs once th…

I'm not 100% sure that I'll say all of this right, but I'm going to wing it. Let's just say you want to build a single reflex bandpass box, but you want to use a sub that isn't recommended for sealed enclosures. How do you find out how large to make the sealed part of the enclosure?

i got my 15 inch MAG installed today in a 2.6 sealed box OMGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGG this things is insane i love it holy chit... it made my hair move this is very deep and very clean and tight i love you thank you for a GREAT SUB im barely pushing it and this thing blows me in half <-----my face will give a more professional review in a few days but for now tat is how i feel

Can anyone help me on what box volume and dimension could i use to get the most output on my Fi ssd full option? Going to power it with a sound magus x1502 1500w at 1ohm. The car is a mitsubishi adventure, a minivan...and what box tuning you could advise,i want to have deep low bass but sometimes i also listen to house/club music...thanks

Would the 15 work ok in a smaller than 3.0 cu ft box? The price is very right, and i have heard the SQ rivals the IDQ, but i don't know if i want to fit that large of a box. That would be nearly double the size of my 1.6 ported 12RLP. So if i went sealed i could save some space, but would that be any louder than my ported RLP? Also, would i lose SQ to the RLP?

Well I finally got to install my Stereo Integrity Mag 15. And I know everyone on here knows I use them and used the 12 alot and love it but man, I love the 15 even more!!!It is still a very accurate sub and has lots of output, lots of output. I barely have it turned up maybe 1/4 gain on the amp and 1/4 gain on the Coustic XM6 and no bass enhance or my EQ lowest setting is 63hz at +1db. Its quite amazing and fun to play with but the best thing about this, is this is probably the easiest sub I've used to blend into the rest of the soundstage! I wouldn't never have thought a 15 was easy to blend but this is. Its much easier to blend than the 12 i used. The 12 is awesome but …

what model is this FI? it says "15 BTL D2 PW PC" written on the magnet with a sharpie, im guessing thats from the builder? but i had someone tell me this is not a BTL, i need this cleared up since im selling it, and i dont wanna misrepresent what it is.. thanks

I am probably about to purchase a new 12" or pair of 12"s. What can you guys tell me about the si's and their ability to function well in sealed boxes? Thanks in advance!! Btw i've got an ed nine.1 for power and i currently have a single 12" IDMax, looking for more output without losing sq.

I am wondering if this sub can come in either of these. I need to wire down to a 2 ohm load. Thanks for the help.

ok im getting bored so i decide to look into getting a sub to play with i have a RF punch P3 right now its ok just wanna be able to say i have had experience with different woofers and right now that is the MAW-15 has anyone had any experience with this sub how is its performance and power handling

Nope
