Subwoofers / Speakers

Have 2 15s 2 12s and 2 10s?

Hey guys first time post, but def. not new to the car audio thing. This is the first time I have used FI products and I was wondering if it is normal to smell just a little coil when the sub in new (mine has only like 1 week of use on it). Im pushing it with a Elemental Designs Nine.1 its underrated at 1200wrms @ 12.5 vdc no clipped signal I checked with the o scope at college im gettin a good clean 7.3 volts from the preouts. I want to push about 1500wrms to it but im gun shy with the coil thing...can she take more or should I just get one more to feed my 30htz @ 140db addiction??

Hello all, Name is Chelsea (Andrew is my significant other) New here! We currently have a pair of RE Audio SX 18" subwoofers in a 10 cubic feet box after driver displacement, ported to around 35-40hz. They are powered by a Hifonics Brutus 2600 RMS Amplifier, it can only run at 1, 2 or 4 ohms. We will be modifying our box so it is raised about 5-7 inches wich will increase it to around 16 cubic feet, and we will be changing the port to preferably 29-30 hz. The RE Audio SX's that we currently have are D4 voice coils and we run our amplifier at 1ohm splitting the RMS between subwoofer's getting around 1300 RMS per SX. We can not do this with the Fi BTL's because they are D2…

i have 2 12 inch FI BL both are Dual 1 ohm and plan on wiring for a 1 ohm load. what would be a good amp within a 300 350 price range. i was looking into sundown2000D mono amplifier. any other suggestions

One of the voice coils on my sub no longer reads 4 ohms. I'm repairing one of my subs right now, and I decided to ohm the other subs just to see if i damaged more than that one. Well one coil is reading 6 ohms instead of 4 ohms. Leads are not broken and they do not seem to be burnt. Coil doesn't appear to be discolored. Any thoughts? Thanks

Time to upgrade! Right now i have Infinity Reference coaxials, and they were good for first speakers, but the longer i owned them, more i realized that they suck. I have 6.5s up front and 6x9s in the back. I'm not planning on buying new 6x9s cause i haven't read one post that is for buying them, or even having them for that matter. I also have a SDC2.5 12" sub and an AQ1200D amp. i have around $200 to spend and have list of component sets that i think look good......but I've only heard the Focal set, and i was very impressed! Definitely feel free to add speakers to the list. I want SQ comps, don't really care if they get loud.....as long as they sound good! JL Audio VR…

I remeasured, new box dimensions are 34 x 30 x 17.5 total interior gross is 8.57 cuft. Port is 6 x 16 x 28. 1 cuft total port area. Do I need more port area? Any suggestions, this is my first box for large drivers. what kind of bracing should I use?

I came across this box and it says its only 3 cubic feet. This does not seem correct. The recommendation for the sub is anywhere from 2.8-4 cubic feet. box link http://www.bestbuy.com/site/olspage.jsp?sk...d=1218009774927 also...if i buy an amp like this...http://www.bestbuy.com/site/olspage.jsp?skuId=9027206&type=product&id=1218009770462 will i get good performance out of this sub because the brand name is like unheard of lol Thanks.

Goal is loud...

How does the Fi BL compare with the IA Death Penalty and Death Row in output, sound quality, and overall?

For the longest time I ran my SPL15 inverted due to my box being just under 4 cubic feet net. I also made sure to reverse the polarity on my pioneer HU when I ran inverted . A few days ago I got bored and decided to mount the sub in the "normal" non-inverted fashion. HU sub polarity setting was set back to normal rather than reversed. The sub sounds much louder now and low end reproduction is much more powerful. I thought by putting the motor in the box would decrease net volume therefore raising the tuning a bit. Doing so seems to have had the opposite effect. Box is tuned to 37ish with sub mounted inverted. Can anybody explain why this happened?

I'm pretty much set on what I want to get. 2 Mach5 IXL 10's 1 Phoenix Gold RSD 1200.1 Ported Box tuned to 34 or 35 Hz Each sub will be getting 600 Watts rms. Is this a pretty good set-up for a good amount of SQ and loudness(Right now I have 2 12" Memphis in 2 supersmall wedge enclosures(Sealed) and 300 watts total) ? Another question about the box. Should I put both in same compartment or each in sperate compartments with their own ports.?

whats up everybody im thinking about buying a 1990 impala to play around with and i was told that i would only have room for four 12' or two 15's. i really dont have a set budget yet but i dont want to pay a fortune for the subs and amp(s) any suggestions? heres a picture of what i will have to work with

In terms of loudness, in a ported box tuned to 34 Hz, which would be louder? Mach5 IXL 10 or RE SX 10"? I know the Mach5 is cheaper, and can fit in a tighter box but I hate that it comes in Dual 2 Ohm. I wish it were Dual 4's. I've seen a review here where the Mach5 SPL got metered and was fairly high with the RE MT. If there's someone here who has heard both(IXL 10" & RE SX 10") please answer.

1 Mach5 SPL12 2 AQ2200s @ 1ohm strapped 147.0 @ 43hz........LEGALLLL Was a local show.....i was loudest by far, next loudest was 4 12 JLs with a 142 legal That is all i have to say about thatttt Mach5 :eek::eek::eek: AQ amps :eek::eek::eek::eek::eek: For comparasion: 12 HDC-A and 500.1 @ 1ohm = 146 @44hz legal in my truck with a semi-similar box

Seeing as im a teenager the goal is defenitley loud!!! Budget for EVERYTHING is gonna be $2000 I have a 2003 ford focus se. with the factory blaupunkt system Few requirements I need to keep my back seat... Aux in is Absolute... Trunk limitations 20" high 40" wide 30" deep Sorry if this is in the wrong section i figured subs would be the best pick because that is, to me, the most important part of the system...

I have a single cab 2008 Chevy Silverado with 2 Memphis 12's but have them in a tiny box. I've been looking for 10's that would suit my needs and have been thinking about 1 Fi SSD 10" but now might go ahead for 2 Mach5 Audio IXL 10's. Are these subs good?(Quality & Loudness). How big should each sub get tuned to 34 Hz? Thanks in advance!

how do you know if the voice coil on a sub is burnt?

Is there a way to convert between the 2 rating so I can compare subs better.

Can't find them anywhere. How much did they retail for?

i know everything is install related, but i want to try to get a general consensus i asked this question on another forum as well subs are DC lvl 3 as far as output, im quite sure i would be happy with either setup. my buddy has 2 12" type r's sealed up and they are loud enough for me (but louder still is better) my goal then is to hit as low as possible with these subs (i listen to rap, so the lowest i would need to think about would be like in "put on": ~25hz) i typically set my crossover around 65-70hz, so anything above that im not worried about currently front is stock, but will be upgraded soon; looking at rainbow and hertz right now.... 12's ported, box hopefully e…

I have a geo metro and I got 2 fi bl 18s in a 11cf box and I don

If I had these speakers. The Alpine SPR-13C5-1/4" 2-way Type-R Series Speakers with these numbers Type-R 5-1/4" 2-way Speakers Power Handling: Peak: 540 watts per pair / 270 watts each RMS: 180 watts per pair / 90 watts each Impedance: 4 ohms Hybrid layered-pulp woofer with rubber surround 1" Swiveling silk ring-dome tweeter Frequency Response: 70 Hz-27 kHz Sensitivity: 86 dB Top Mount depth: 2-3/16" 1-year Sonic Electronix warranty Will the sax 100.4 from sundown blow these speakers just wondering. Blew my last set of speakers and have these just sitting around?

So i just got my components in the mail today, and i was very excited. lol. but then as i take out one of the drivers, i hear something inside the dust cap rattling around! I tested it out and i can hear it rattle at low volumes, but it goes away at higher volumes. Do i have to send it back in, or is there anything i can do? The rattle is only in one driver.

Could someone please explain how these work. I know of the advantages of sealed and ported over eachother but where do these fall in?
