Subwoofers / Speakers

so last night i was on my way home from the tech n9ne and brotha lynch concert bumpin the new kutt calhoun cd and i noticed on higher notes like 50hz-60hz that my power hx2 started making this slight rattle type noise. whichis funny cause i just posted yesterday bout finding recones. well i thought it might be a lead slappin and doesnt look to be that. how can i determine if its coil rub? it kinda sounds like its comin from the dust cap area tho. this has me scared/sad cause i just got my sundown amp and i know i didnt over due it yet......... SO SOMEONE PLEASE HELP!!!!!!!

hello everyone i was wondering if any of you may know of any good sites online that sell just the mid bass drivers in 4 " i have a nice pair of tweeters up front but i wanna change my door speakers that came with the car to some mid bass drivers. it seems the car came with component set speakers stock but who ever own the car before took them out and replace the door speakers with 2 way speakers and upgrade the tweeters and i would like something with a lil bass in my car so it wont be so flat.

I recently picked up the WT3 and have been playing around with it a bit. But I am a little unclear on a parameter I am supposed to enter in. When having it calculate VAS you need to enter in the Piston Diameter, What should I enter? ie 15 for a 15" driver, 12 for a 12" driver etc. OR Should I enter in a calculated diameter from the Sd? Example a 15" driver is ~12.64", 12" driver ~9.73" etc. Thank you.

I have a 95 s10 which im planning to put some new gear in. first i will be using the new brz3000.1D ( which is cea certified btw) it is 3000w rms at 1 ohm. I have enough room to fit 2 15" btl's, but i was wondering how much of a difference going with 2 btl 12's would be compared to the btl 15's? i have a 150 amp alt and i will be using the biggest batt. xs offers. Let me know what you guys thinK? thanks, kyle

is there such a thing as 4" or 4x6 drivers that can handle midbass or are these things just not meant to play it? If so who makes one?

Would a Kicker 750.1 zx be an ideal amp for a 15" 4 0HM L7?

I noticed that the BL differs between the two options on Fi's website. Do they perform the same? I see that they are almost exact in sensitivity. How does this work if the motors are different strengths (different BL's)??

I have an Alpine 12" Type-R 1242D subwoofer and I'm currently looking at an Alpine MRP M500 amplifier. The sub puts out 500 watts RMS (dual voice coil, 4 ohms), and the amp puts out 500 watts at 2 ohms. First, how do I bring the sub down to 2 ohms, like people say they do? Also, does the amp need to be more powerful? After measuring the power it can put out specifically, it came to around 600 watts. Is that too low or too high? I'm looking for a good, deep bass, mainly for rap, just for reference.

I disconnected my speakers and was listening to my sub by itself and I noticed that I could slightly hear some words. Everything sounds good and you cant hear it when the speakers are connected so I was wondering if this is normal.Thanks in advance for any help.

I was wondering what amp will be good to use on the dd 1508's? Just gonna be running one 8 on my center console... ALso, anyone got one for sale? Im ready to buy asap. I have paypal, let me know.. thanks..

I've got about 4.5 cubes gross to work with sealed for 3 10s. I have 500w rms per sub. I want it to get loud and also pick up the lows exceptionally well for a sealed box. Would like to keep it around $150 per driver. Subs considered: Mach5 ixl Dayton mkIII Audiopulse epic

A drill went through my subwoofer (foam surround, not the actual subwoofer) while taking it out of its enclosure. The hole is about an inch long, what do I need to do to fix it? Is there some sort of kit I can buy, if so where at?

Looking at a dc audio lvl3 15"- would i be able to get good sq out of this if i put it in a sealed box?

im running a rf power hx2 15 d2 on a saz1500 at 1ohm around 1000rms. ok im wondering cause this is my first sub that can handle some wattage and my first "real" amp. which it can kill this sub if i turned the amp up. if i happen to phuk up and kill it is it possible to get a custom recone for my hx2? cause ive searched alot to get one just in case. but i thought about it and if imma get one why not get one with a flatwound coil and stiffer suspension? who/where should i begin to go about getting this done? ****? thought id ask u guys b4 askin them a bunch of questions maybe someone knows a better place

I was reading the topic about running 1 vc on a dvc sub, started reading on a link provided in one of the posts by Impious and it got me to thinking. I have 2 SSA Icon d1 subs and want to keep a 1 ohm load, which would be the better option for best daily output off a Sundown 1200v2? Run each vc per sub in series then parallel pairing the subs or parrellel per vc and series pairing the subs? Both subs sharing airspace in a ported box. I hope i am explaining this correctly.

so when u get a DD sub ....just hook it up and "slap" the shit out of it

I have heard a million times that running one voice coil on a sub with multiple coils is wrong. I read an article by Adire Audio years ago and they actually suggested running on one voice coil in certain situations. I also remember that running one VC while "shorting" out the second VC would change woofer characteristics, I believe it raises QTS if I remember correctly. I understand that it would basically halve the power handling of the sub. What else does it do? The article also says something about a sub with 300 watts wasting 298 watts as heat, and only using around 2 as musical energy. Are speakers really, that inefficient? Here's the article if some of you want a g…

Well, I think I am leaning towards two sealed twelves now, instead of an icon or xcon in a large ported box. Since IA doesn't post any specs on their woofers, it is hard to model responses and compare these two woofers. If I were to put these woofers into an optimum sealed enclosure, which would be better? What I mean by better is which one would give me the lowest extension, and upper extension, and the best SQ? Sundown shows an F3 of 44hz in a 1 cu. ft. box. that isn't too bad, and should dig pretty deep, but I cannot tell anything about the LI. They are both rated at 600 watts which will match nicely to my amp. They are priced the same. They both have great re…

Just like the title says, Xcon VS. DC LVL 4XL If they are both 15" Which would be a better subwoofer that will sound good with music while still pounding? and would either of these be able to fit in the trunk of a 98 honda accord coupe?

Thinking about picking up this sub. Oz Audio Matrix Elite 15" . I think its rated at 700 rms- my amp ,boston gt-28, puts out 1100x1 @ 2 ohms which is what this sub would be wired for -2 ohms- since it is 4 ohm dvc. Would this be a good match?

When does the size of an enclosure start to be too big and start affecting performance? The reason I'm asking is because I was thinking of using the current box I have (it's for a 12") and building a faceplate for it, so I can fit a 10" in it. The box 1.21 cubic feet. I was looking at the 10" Icon, but after displacement there's still about .19 cubic feet extra. Is this too much extra volume?

What are the three most commonly used slug types in sub woofer motors and what are their advantages? (I'm looking for three EXACT or VERY CLOSE answers)

Any thoughts on which one of these 15" subs would be helpful. RE Audio SE '08 series aluminum spoke basket design---OR---Oz Audio Matrix Elite series??? Both of these are the same price which makes it even more difficult to choose. Looking for SQ so it will be going into a sealed box. Both are 4 ohm dvc wired to a 2 ohm load as my amp is only 2 ohm stable (boston acoustics gt-28 1100x1 @ 2 ohms)

I don't know what to put in my dash, it has stock 4x6 speakers, I want to try to do a 4" comp set or something like that, or should I just replace with coaxs? I know they make plate speakers but I don't know which way to go. I want a good clean sounding front stage with alot of bass, and crisp clean highs too. Help please.

hey guys im going 3 cu ft for 2 level 3 12's what kind of tuning do you guys use for these for rap? keep in mind just cause its rap i dont want it to sound like muddy ass..lol id like it to be musical..each sub will be getting 500 watts..this will be my first time with ported and i dont know shit about port area, volume all that stuff..and im having the shop build the box for me and install it, so if you guys can give me some numbers i can write them down and hand them to the shop..by the way reason im going with 3 cu ft is cause on there website it says 1.5 per 12'' unless you guys know something that works better
