Subwoofers / Speakers

Hey guys i'm playing with kerf port design. But i'm clueless on how big the kerf needs be, compared to the size of the port. The port i'm using is 2.5 x 37.5. Should the kerf be the the same size as the port width or half the port width? Here is the design so everyone can see how i'm tring to get the kerf.

I got a new car last year and was not going to put a sub in this car because I don't want to loose the room but I can't take it anymore so it time to find the right sub. I have a Phoenix Gold Xenon 600.1 to run what ever sub I get. so I have 600-800 wrms to give it. I want to run 1 10" sub sealed in a small box say .5- to may be 1 foot. I have had PG subs in the past and liked them a lot. I tried a RE SE12 a few years back RPLI12 and 8s. I had the 12 ported and they did get low but for some reason I like 10s better so I ened up with 2 PG rsd 10s in my last car. I listen to all kinds of music. So I see SSA has a new sub coming out soon so I was thinking about the GCON a S…

I'm planning on buying a new system during winter for next summer and I wanted to go with 2 15" sub in a ported box. I know its a hard question to answer but how much power will I need to run them? I was looking at the RE SEX15D4 but I havent made up my mind on them 100% yet. But in general how much power would be nneded to run dual 15"? Should I go with 1 amp for both or 1 amp per sub?

Hi. I am building a box for 4 of the MJ-18's. They will be used for home theater and music. So I think im going with 4.5 cubic feet each and tuned to 30hz. Should each subwoofer have its own chamber or should they all be together. If they are together how many ports should I use and what dimensions should they be. Thanks alot!

ok im trying to help out my homie. he wants to get 1 15'' ssa icon... can you run that on a jl audio 1000/1v2 amp? thanks

Alright, this just might be me being stupid but here it goes. Someone locally has Three SA-12's up for sale and i was kind of curious what your opinions on this was. Iv had no experience with SA-12's at all, and i was only curious if this would be more of an upgrade or a downgrade on my part? Id be keeping the amplifier i have now, an AB 100.1 so ill be running about ~1500wrms. Im thinking if it would be an upgrade in my part ill trade him my BTL for his 3 SA-12's. The main reason I think this would be a good trade is 2 reason: -more cone area with the SA-12's -more motor force with multiple subs So if the QUALITY of the subs is on par... i might try this out. Not s…

hello, thanks for any help in advance. i'm looking at ordering my first mach 5 subs ( ) and just wanted some recommendations as to which ones' i should get and bopx sizes. right now i have a crappy 15" kicker cvr in a ported box tuned to 35-36hz. and i want something to keep up with it in spl but also have better sq (which shouldn't be hard since kicker sucks, but it was damn near free). i have 650wrms to play with so i'm thinking about 2 maw 12's. how would they compare sealed or ported? if sealed works (kinda hoping it does, miss the lows my box now doesn't get) what would be good size, was thinking about 2.5cuft after displacements? or ported, but i'd want it tuned lo…

Can anyone give me a design for my ext cab gmc sierra. Dims are 48 W 22 H 24 D. Please guys my current box sux i have 2 fi bl 15's

Guys, I have a really dumb question that I'm a little embarrassed to ask. I'm in the planning phase of doing a sealed fiberglass sub enclosure for a friend. My personal sub setup is infinite baffle. I did one sealed enclosure like 5 years ago and have since forgotten the answer to this question. When the sub manufacturer gives you the cubic footage for a sealed enclosure (in this case, .75 cu ft), does this INCLUDE or EXCLUDE the displacement of the sub itself? In other words, do I need to add to the .75 to allow for the space taken up by the magnet/etc, or do I simply make a box that has .75 cu ft of air space? If the answer is that I have to add the displacement of …

I have had an old SX laying around for a couple years and finally sold it (with box and amp) to my brother for $200. He was getting it installed today and the guy installing it said one of the VC was reading 0 ohm. I havent been involved with car audio for probably 10years and forgot what little I used to know. Can I fix this or is it now a paperweight? Maybe I am hanging onto nostalgia, but IIRC Resonant Engineering was respected for quality and value before the buyout by US Amps when prices shot up. Furthermore IIRC, the owner of RE went on to found FI car audio, so perhaps they would be the ones to ask? Any feedback would be much appre…

what happened to this sub? and has someone listened to it recently? would love to test it against the MAG or IDMAX or my incomming RL-p

i have an audiobahn 4002T amp and i am gonna be getting some money from my scholarships that i didnt use for tuition. i dont have a whole lot of money and i am runnin stock battery and alternator so i cant go too many watts. i may get a new amp someday, but if i do it wont be over 600 watts. anyways, i have 400 watts bridged at 4 ohms and i am trying to figure out what sub i want. i know i want 1 12" and a ported box tuned to 30-32 Hz. i want pretty decent SQ, i want it to hit low, hit hard, and get loud. so basically LSQ. i am between the RE SX and the Rl-p but i just cant decide. since the SX is only dual 4 ohm, i can wire it to 2 ohms or 8 ohms. i am a little worried …

im working on a stealth install. so hewres my situation, the way im doing my doors is im taking off the carpet, mounting the speaker and puting the capret back over. it was designed for midbass aplicatuions becuase carpet shouldnt harm like 80-300 herts to much but hows it going to effect the upper midrange of the 302's if i buy them>?

Hello all i think i found what i am looking for in 2 ..15 inch subs.. the zcons..... I am putting them on a cres..5500 . I hope this will do the job for a everyday use(really 10-12) times a year.... I hope this is a good choice..... Anyone with experience with zcons let me know... Ty in advance.......

This thing was already in a box when i got it so i decided to just throw it in the car and see how it sounded. The enclosure it's in is pretty beefy but it's sealed, which i know wasn't recommended for that sub. Probably about .85 cubes if i had to guess. Anyway, wired in parallel for final 2 ohm load at the amp. Amp is MTX 81000d rated 1000wrms @ 12.5v and i believe it should be pushing around rated power. Anyway the excursion on this thing is SICK, kinda moves like the old eclipse TI,s. However, I am disappointed in it's output. I have had several single sub setups in different cars, ported and sealed, and honestly, it doesn't seem any louder then a kicker comp 12 w/ a…

I am getting some 5 1/4's for my mothers jeep 2006 Wrangler because her roll bar speakers sound like butt. I don't really want to spead more than $50 and have come across a few that I am curious about. http://www.onlinecarstereo.com/CarAudio/Pr...ProductID=13539 http://www.onlinecarstereo.com/CarAudio/Pr...ProductID=15582 http://www.onlinecarstereo.com/CarAudio/Pr...ProductID=16666 The problem is that she doesn't have an aftermarket cd player and I know that the stock radio is not putting out the best sound quality or power. But the front stage in her car sounds great and looks like it has a seperate tweet and speaker. Then you at the roll bar speakers and they are t…

I am building a new enclosure to put in the trunk of a car... It will be built with the sub facing upward, so which direction should i face the port? Should it fire towards the front, side, or back? I do not want to fire it towards the back if I do not have to because it make the trunk lid rattle more... Please help me w/ this asap... Thanks guys.

http://cartoys.com/default.cfm/t/Car_Audio...rs/o/Subwoofers Well, as you all might but probably wont know, I have to go to cartoys to get a decent setup. Im getting 4'' in the front, 5 1'4 in the rear, and I want a sub. Now, I want to get all in one thing, so I dont have to bother to upgrade for a while. Hypothedicly, saying I were too, what do you think I should get. I have a rear deck, and in that deck I have a med kit. I can take that out and get a rear deck cover, so thats like a vent for the sound. So eitehr I sink an 8'' in the deck, or I open it up, and get something in the trunk. Odds are good I will go with the trunk idea, then gettin on in the back deck. So, su…

hey fellas yes im a noob on this system stuff ok so take it easy on me lol.. well ive already spent alot on my system. it bumps pretty good now but im a bass freak, but now i want low clean bass that travels like a mofo. i have an 04 extended cab right and i currently have 2 12" kicker cvxs in a ported box just chillin on top of my seat(ghetto i kno) they are bein pushed by 2 alpine pdx 1000.1 so 2k watts to each speaker. my problem is i want more deaper bass and i also wanna put the box under my back seat so 10" woofers would be my solution. i kno its gunna have to be a custom box. i was thinkin bout 4 mtx 8500 cuz they would go perfect with my amps or 4 kicker cvx but…

I am really stuck and what subs to run.. 2 Audioque HDC312 or 2 Fi BL. I have a 4.0 cubic box after displacement and port area Its tunned to 33hz. I will be powering them with a Sundown SAZ-3000D. I can't make up my mind what I want to run

Gotta 92 deville and Im just trying to get the best bang for my buck. The seats dont fold down at all and it has that big ass metal piece blocking most all of the sound from getn into the cabin. So Im looking for a sub that gets loud and is able to take them lows. Im most likely going to have it port tuned at 32-34 hz.. Im leaning towards a fully loaded 12" FI Q, But Ive been looking at the 12 IA LI's also, They seem to get really loud and take the lows... Or possibly a SA 12? Whats ur opinion?

Found a helluva deal on ScanSpeak D2904/6000-01. Check out their prices at Madisound then go to www.pacparts.com. Click on Consumer Electronics and do a parts search for Alpine Model Number SPXF17T. It will pull up a page with all the parts associated with the sets and you will see the part number D2904/600001. It is the raw tweeter of the set sourced from ScanSpeak and guess which model they picked? It is the same exact specs wise. Just says lowly alpine on it......and they say there isn't a price for the label. I just ordered a set to go with the Lotus Ref's and I should see them in a week and a half. They don't stock them, they source them right from Alpine, t…

Just wondering if ne1 went Sunday,about 50 cars were on hand.It was hot as *ell,got to see some decent cars but wasn't too impressed,had I had my ported box for the Mag I would've definitely got metered.The loudest vehicles were a pick-up(JL stuff) & some rust bucket on wheels ,dont know what he was rocking.Nonetheless we had a good time,got some free t-shirts & other misc. stuff.
