Subwoofers / Speakers

Hi, A friend of mine is looking for an 8" midbass speaker. He has several sizes speakers in his car ! It's not really perfect as ///M5 would have done it, but it sounds so good !!! It's one of the best sounding cars in my island : loud, nice and gets low when needed ! The 8" will be powered by 2 channels of a JBL amp, a pbx 300.4, so about 125 watt rms per side at 4 Ohms. He runs a second JBL amp (100.4) on the smaller speakers and tweeters. Electrical is very good. He has 4 Sundown saz 1000's on 2 SSA Xcon 15" in a small Renault Clio (build log here on ssa forum). So... All his speakers are in the front doors (2 doors car), and he has just told me that he doesn't care ab…

what differences would i notice with a 12 inch with these differnt box sizes, 1.0CF, 1.3CF, 1.5CF would i loose any sound quality or puchiness as i went bigger? i ask becuase i found a way to make a bit more space in my truck and as you all saw my box design in another post it ended up around 1.25CF after displacement. if you think it will make a "good" difference i can crank it up to about 1.3-1.4CF after displacement.

ok my friend will build me a box in his wood shop but i need to get him plans. SI 15 MAG, ported. what do you think of the aeroports? is it worth it for only $25 extra? most people use 2 of them at $12 each. power will be a hifonics ZEUS 1000D 1000@1ohm it is a lexus 2002 es300. should be the same as the new camrey. people have put 2 15 in there before with a almsot bent box. i only need 1. the red strap is what i will be using to hold the sub in place, i would also love there to be ehough room to put my trunk battey next to the box. it is 6.5 inches wide demetions are (IMG:http://members.cox.net/havok/trunk.jpg) THANKS FOR ALL THE HELP I AM FINALLY BUYING A SUB TO FINIS…

At high volumes my 18 makes a hollow pop sound. It sounds like someone is flicking the dust cap of the woofer but louder. First I thought bottoming out, but it happens at frequencies where there is not high excursion. This problem also happened on my sa12s I had previously. So now I'm thinking it is my amp, but why would the amp make such a noise? Any ideas? Coils read good, no clipping, constant voltage.

I am beginning to think I should go sealed with my 15" SSD. Before you guys say no no you'll lose output let me tell yuo whats up. I have an extremely tiny trunk that is damn close to 15" tall maybea little more, i am not sure. I have my sub ported right now with the sub up and port back. the box's height is 13inches at the moment leaving only around 2 inches for the sub to breathe. It cause so much more rattle like this and I was wondering if you guys think sealed facing it towards the back of the car would sound just as good if not better? The reason why I can port it towards the back is because the width is only about 20" from trunk hinge to hinge which cant fit …

Hey all, I just put two DD 1508's ported in the back of my extended cab f150, and to be honest they sound like poo. They do get loud, but notes just run together, no definition. That being said I'm thinking about offloading them and trying two maw15's sealed. I'm curious if these are more of a SQ driver, for the price they are hard to say no to.

Hey guys, Recently I have been really unhappy with my subwoofer. After my install of the HAT I haven't been using my sub. I have it all the way down on 0 just because it sounds so sloppy. My amp pushes 400 watts at 2 ohms. Give me a few suggestions on a good sub to blend with my hybrids... Edit: Oh and I'm gonna go sealed Thanks, Mike

heard from alot of guys that this would be the way to go. sq wise. never really done too much research on this topic so i have a limited understanding how all this works. can i just swap the co axles for the mids? or do i need a crossover? also i plan on switching my jbl gto 628 6.5's with crescendo pwx 6.5 mids. heard nothing but good things about em. all amped on a rf 400.2

I got a question, everyone says that playing a subwoofer below the port tune will cause the subwoofer to be unloaded, and with too much watts it will "bottom out" is this unloading the subwoofer basically becoming a sealed box with a 4", 5",3" etc hole in it (loss of major amount of bass) , or the unloading making the subwoofer box be like an infinite baffle, decreasing power handling, but increasing efficiency? if it is infinite baffle, would it have a similar 6db/octave (i think this is close) roll off instead of a usual sealed boxes 12db/octave

What do we have here?

I had a 08 Fi Bl18 on apprx 1000 watts 7.5 cubes tuned 32hz and I liked the output. I am wondering considering the Bl is a more spl orriented sub and the Fi q is mor sq oriented how much out put am i going to sacrifice if i went with the q. I have now a Fi BL18 09 model fully loaded on ~1500 watts in the same enclosure. I havent heard this one yet as the amp is pending delivery. the next question is would a Incriminator Audio DP 18 in the same box on ~ 1500 watts. would i get the same or more output than the Bl18 and better sq possibly as good as the Q? the reason I ask all this i have no way to audition any of these subs and, Its kinda expensive to just buy 'em to try 'e…

I've been reading a lot about those new mids/components coming out, ED's big midbass, Adire's Extremis, RE's XXX 6.5, etc. and was wondering what some people thought of them. Me, personally, I can't wait for the XXX, mainly because I'm a big RE fan, and they are supposed to play from like 60 hz to 4-5khz clean! now that is a feat, but we'll just have to see how good they actually are when it gets closer to release time. Also, that XBL ^ 2 4" "full" range speaker, jeebus, that sounds impressive, but as i said above, we'll have to see. :ph34r:

got 1.5 cubes for sealed / need advice on subsafter some careful considerations, i cant do a ported box.too much space. i can do 1.5 cuft SEALED after displacement. i got the amp to push these @1000w rms. ive been going back and forth with different configurations for about a week now, my head hurts . my paycheck came today and i wanna buy a sub before i run outta money. so now im looking for a sealed configuration for a stereo integrity mag v3. OR two sundown audio e10 v2's so... 1- does a mag v3 work well sealed @ 1.5 cuft ? the subs web site recommends 1 cuft. will i get more output with the extra .5 cuft ? 2- which will give me deeper bass ? the e-10's or the si mag…

Had one sitting for 4 years thought the motor shifted finally took it apart. The coil had hard bottomed a couple of times and put a lip on it. Any venders here make a kit? also would it be it be feasible to recone into a 18" http://fixmyspeaker.com/product/18-6-spoke-frame/ would this work? thanks.

Just keep in mind that this is going in the cab of a Del Sol. The subwoofer enclosure will be fiberglassed of course directly behind the two seats. The enclosure will consume literally everything rearward of the seats. I might own a very powerful amp soon that will be able to anihilate the 15, let alone a 12, or even 8's. So now my options are totally open.

Redoing port soon and need advice. Sub is a Fi Q18, 6 spoke basket, SPL audio recone, on under 1k. Port is 12" plastic pipe. I want it tuned at 29 and I can get there 2 ways. 1. 34" of pipe internal and 2" external giving me 8.08 cubes. And 2. 28" internal and 6" ext. giving me 8.48. How much would the extra .5 cube affect the sub. (Fi recommends up to 10 cubes for 1 Q18)

Ok I have a basket out of a 12 and a motor out of a 10 I wont to use together to make it a way better 12 then get it reconed. I was able to unbolt the motor for the 12 but I still can

Should I get the eD 13Av.2 http://www.edesignaudio.com/product_info.p...products_id=554 or Fi Q https://ssl.perfora.net/www.ficaraudio.com/...view.shopscript I know everybody going to choose Fi Q but whats the advantage of this sub over the 13Av.2

im thinking of getting 2 mag 2d 15's for my van I want SQ mostly listen to metal and rock so kick drum and bass guitar is important. size doesnt matter got most of the back of my hiace to fill up. so what size enclosure, ported/sealed, tuning, power ect. and maybe any nice amps you guys know of. I was thinking of getting 4, what you guys think of that? a waste of time? just thinking that if sealed is better for SQ then just get more subs for more spl. money isnt an issue. not buying right now but gota plan and see how much i need to save. and if you wouldnt mind could you explain tuning an enclosure for me i dont have a clue about it. thanks.

my first post... i never heard of the magnum before and for only 350.00 why not try it out... and if i dont like it.. sell it... no problem there... i like to explore new things that many people dont anyways especially car audio.. when someone says "whats that" "how many subs you got in there" that right there is worth every buck i put into it... but to the question... i'm pretty set on the magnum 15 so whenever the next batch comes in... please let me know... 1. i really like the memphis amp because of electrical issues but i can't decide on which one?? the 16-mc1000d or the 16-st1000d??? anybody know if there's any difference??? 2. will 1000 watts be able to really g…

Ok a lil background, puttin together a system for my rsx and so far I've got 2 18" Xcons (putting them in separate sealed boxes because both won't fit in the car without folding the seats down) with either a crescendo 3500 our a used saz 3500. For the front I've got polk audio mm 6.5" components and for the back seats mm 5 and a quarter coax. For electrical I've got a mechman 270 alt and two xs batteries. My question is whether I should get a set of morel maximo 6's and a set of morel 5c's. I've seen a lot of people say good things about the morel's I'm just wondering if it would be worth it since I already have the polks. I would try both to see which ones I like and se…

i have 2 eD k.44. there is a rattle in one of them in between the cone and the cilinder where they meet. i dont know what this is. can someone give me any advice? al

Hello all, A few years back my subwoofer and head unit was stolen so I've been out of the bass game for some time. Luckily, my amps were left behind as they were in the false floor in my Xterra. Am looking to get a new head unit and subwoofer/box. I currently am using an Alpine MRD M1005 amp and want to wire at 2ohms to deliver 1k watts rms. I am looking for something that slams hard and clean, and I listen mostly to hip hop/rap/rock/alt rock type of music. I am also open to building a ported or sealed box - although I may prefer sealed for ease of construction and to save space in my Xterra. If I go ported - I am not sure which direction to fire the sub as I've…

So I need some testimonials. I've read most of the threads related to them on here, I just want MORE! nah not too much. I've just gotta nut up and do it. I'm thinking about putting a 15D2 in a 3.0-3.5 cubic foot ported box, one tune to 32 hz or so, another to 45 or so. How much port area does this sub like? Also, I'm a fan of quick, tight bass. Will this setup deliver for me? I'm forward-facing it in my trunk, and sealing off behind it. I was just a little worried because the group delay is 2.5 times that of my current setup of four sealed flat cone ED 12K's. And the Le on the D2 seems high, but does it make a difference if the sub is wired in series or parallel? …

OK I made a new box (sealed) but I dont know how many cu.ft net it is? the box it the inside is 12"D 27.1/2"H 23"W with a driver displacement of 0.25 how many net cu.ft is it ????? help!?!?!
