Subwoofers / Speakers

Ok guy i need some input, im going to be running a LVL 4xl 18 in my 2008 HYUNDAI ACCENT hatchback and want to know what config you would use on the box subs up port back or what?Also how many cubes should the box be 8-10 i want this box to play low but not to low, ie (GROUND POUNDER) My main goal is for the box to reek havoc on my car.

would the AQ 1200D be a good combo with two 12" D2 L7's?

Hey, I just got a 15" BL in a a 3.6 cube box tuned to 33hz. It pounds and rumbles hardcore, but doesn't move enough air to make me happy. So I'm looking for some new setup ideas... My car is a 1996 Cutlass Supreme, so I don't have tons of trunk space. But I'm looking for something ridiculous that I can fit in here. Maybe 2 12"'s or something like that. I can proboly fit 2 15" in a sealed but I want ported So what are some ideas? I've looked at Orions and DD 9512 or maybe 2 13w7 even though there crazy overpriced. What are your opinions?

Ok so i have a 10" alpine type E laying around and i have a 66 bug with an amp missing a sub. So i got this crazy idea of building a box for the sub to put in there. My question, I only build ported for personal reasons but i want to know what should i tune the box too? I'm giving it 1.5ft^3 internal space not counting sub or port. I was originally going to tune to 32hz, i like low bass but i know its only a 10 and not the best, actually i have no experience with alpine. I can only compare it to my RE Audio Sr10 which wasn't to bad with a 1ft^3 box tuned to 30hz in my other bug. What would you tune this sub too? powered by about 200wattsrms. I also listen to ALL types of …

Just wanted to know if these to subs are comparable and if so, which one would you choose?

can anyone find the t/s parameters for these. I've looked everywhere and can't find anything. Thanks!

I just wanted to know, Is there a way to calculate how much power handling drops below tuned freq in a ported box. And how much power handling drops in larger ported enclosures, Other than win isd. I mean is their an actual mathmatical formula or no? Like for example I have 2 Fi Q 15s with BP power in a box that is 9.5 cubes gross 8 after the port @ 33 hz. How do i figure out how much power handling I have in this size of enclosure and how much it drops below 33 hz? Or does everybody pretty much play by ear and listen for bottoming out?

whats should i go with dd or nightshade would be four 12's of ether. being pushed but two saz 3000d's strapped

This is by far the single best investment I've made in yrs. Everyone hates doing recones cause of cleaning the dreaded basket. Fear no more! Took all of 5 mins. to clean.

i need some help im planning on buying a 18 fi bl sub in the next couple days and im going to run it off a hifonics 1606d and i was wondering if i should go with a dual 1 ohm or dual 2 ohm?......

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

This is one of my Fi X 12's that I've recently burnt the leads on, and I'm in the process of repairing it. Its hard to see, but in the last pic i have the tensil leads unsoldered and the copper leads from the coil ready to be soldered to the new tensil leads. I paypaled the money for the leads and dustcap to Fi so now im waiting for them to come in!!

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

But what sub do you think would be better in a 2001 toyota celica gts, 2x 10" SSA ICON D1 or 2x 10" FI BL D1 Powered off of a SAZ-2000D

Goal is loud...

Please correct me if I'm wrong. Does polyfil slow down the air in the box and make a sub sound as if it is in a larger box? So say I have a pair of 15s and they require between 1.5 cubes per chamber and 2 cubes per chamber each sealed. Say I put them in 1.5 each, could the appropriate amount of polyfil in each chamber really make them sound as if they are in 2 cubes each?

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??

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?

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'm considering an ixl-18 for home theater, however as I don't have any money (yes, I need to sell something to buy the 18 ) I am limited when it comes to powering it. In this case, power will be from a harmon kardon receiver. I can comfortably massage 120wpc (rms) continous from the unit without a second thought. Modeling the driver in a 7cuft/19hz vented box in winisd shows me 111.5dB output 19hz and up at 240w.. I know the receiver will easily exceed 120wpc, and being that this is a dual 2ohm driver, I can reasonably expect 240wrms per coil for short bursts. Thermal limitations will come into play if it needs to supply that much power for extended periods though,…

Anyone know what it is? :bigclap:

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

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.

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

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.
