Subwoofers / Speakers

I keep reading about deriving an Xmax number from BL. How is that done, and how acurate is it? Please enlighten me.

Hey guys, I'm building a box for a S8L7 sub and had a few questions. I want to make the largest reccomended sealed box which is .75 cubic feet for this sub. now, a 12x12x13.25 box with .75 thickness would give me 0.74967 cubic feet which would be dead nuts for what I want. now is the .75 reccomended volume including the volume that the sub will take up or do I have to make the box volume .75 plus the sub volume? Also when calculating the wedges, Kicker reccomends a 2x2x.75 wedge. correct me if I'm wrong, but I calculated the wedge volume to be .0017 cubic feet. Where should I put the wedges? are they required in every corner? thanx... dan

Anyone got a large Stereo Integrity logo as jpg, .psd, .tif, etc i want to make a speaker grill, but i need a logo so i can etch out some plexi. travis

sorry, for missunderstanding,

What would be louder? Currently have a bl 15 in a 3.1 cu box. I was wondering if two Sa 10's in a walled trunk would sound louder then my one 15? I dont know if this makes any difference but my 15 is firing upwards in the back of my car.

Bought an SP4 last night and was wondering if anyone could help me with a design. My max dimensions are W: 38" D: 38" H: 42" or more was looking for a tuning of 30-33 hz if possible with a slot port design. will be running off a Rubicon 2500

nick whats the Xmax of the Mags?

hey everybody, I've been debating over some time what my next set-up should be. Right now I have 6 JBL GT5-10s in the trunkspace of my Golf. I'm looking for something louder; I'm thinking of 2 15s...I have around 7-8cu-ft to use. I want something that will shake the ground, not buzz the ears. So I'm looking to tune them around 28hz. I've been looking at the Fi BTL's but I have never received any e-mails back from anyone there for over 5 months... any body have any ideas as to what sub I should look into? Some that have crossed my mind are: :: Orion HCCA :: AudioPulse LMS-Ultra :: RE Audio XXX :: DD 9500 series anyone have any other suggestions? Also, I'm in Canada, so shi…

I have a 2g wired the output my car, don't want to get a new alternator for subs so everything is stock other than the wires and 200a monster fuse. Getting a soundqubed 1200.1 and need hell choosing either 1 sunfown 12 SA or soundqubed hds 2 in a custom box and maybe an extra battery. Need to know which ones better or what's best for $600 for subs, box, wires, batter. Which would shake up my car? I plan on powering them 1000w or I was going to get 2 but if one in the right box would do temporarily id want to save money since I'm only keeping the car for 4-5 months more. What do you think

I have a 12 spoke SI D2 and right now it is running in a sealed enclosure and it is not suiting my needs. I was told if I ported it, it would be a whole other sub. Supposedly sound incredible. Just wondering if anyone could help me out with some box dimensions for a ported enclosure. THe best way to get ahold of me would be to email me at [email protected] Thanks Adam

Does anybody know if the generic grills they sell at Parts Express will work for the 302's? If not, do you have any suggestions on grills for these?

I keep coming on to the boards and looking at everyone setups, and god its making me want to buy some Magnum 15s. I already have 2 of the 12s (claw basket) but dang im such a basshead. Oh well, i guess i can feel lucky that i have the original prototype. (its still not a 15 though) lol. oh well, have fun with yall mags guys

hey I need help seeing will the SAZ-2500d be over kill for my Kicker Solo X 12 its dual 2 ohm wired down to 1 ohm or will it be okay so someone help me please write me on here or email me at [email protected]

If i bought a 15' mag right now would it be the prototypwe style or the old style? did the new ones come out yet is basicly what im asking, abnd if not when do they ship.... thanks

can someone tell me the general frequency ranges for each speaker or is it personal preference? thanks guys -tweeter -midrange -midbass -subwoofer

All of these would be powered off a Sundown SAZ-2000d in 4.5 cubes tuned to 33hz. Was just curious about this because I'd like to eventually get an SUV and would like to do one of these setups. I know this is a matter of opinion, but I'd like to see how many opinions lead more towards what out of curiousity. RE Audio MX 15 DC Level 4XL 15 SSA Xcon 15

I've done about 4 different setups in my single cab Toyota pickup all involving normal subs behind the sea,t but fail in the size of box, ports, and overall SQ. So now Im taking my DD 1508s out and putting them in a different vehicle but want something for my single cab still. I've tried shallow mounts as well and wasn't that impressed with it so I am now leaning on something that's gonna make good bass in a sealed enclosure as small as possible. I haven't done much research on mid-bass subs or speakers and was hoping for somebody to point me in the right direction. There is no way I am going to try and do anything ported anymore...it just wont work, something as smal…

before I start building boxes and wasting money I want to ask for your guys help/opinion. I know there is a manufacturers spec for a box buthave any of you ran a single 12 zcon before? if so what size box and tuning did you try? mine is going in a 02 cavalier coupe. I can go 16 inches high 22 inches wide and 32-34 inches long depending if I want the amp on the back of the box or not.. but just looking for some input from people who have had experience with one before.

I'm looking for a sub to go with my amp its a da7232 old school. Last time I used it was on a nightshade 12 v2. The setup wasn't optimal so I'm not sure on its performance. The amp is dual mono 2 ohm. Suppose to put out around 1k per channel not bridgable obviously. It will be going in the back of a suburban behind the 3rd row. So I have a decent amount of space but not unlimited. Any suggestions will be appreciated.

and it was like a driver that you could attach to a subwoofer box that was an alternative to porting or sealing a box. I belive it was called an Independant Radiator Driver or something to that nature. It looked like a regular speaker... had a cone and surround and what not but had no motor and i dont belive it had magnets either. So my question is... a.) if anyone knows what the hell im talking about b.) if so have they heard them in action

i promised you guys this AGES ago.. well, its finally been built and... it doesnt fit! LOOOL! oh well, i cant wait to hear it anyway, heres some pics - http://www.talkaudio.co.uk/vbb/showthread....4648#post964648 il report back when i get my headunit back, then i can have a listen

I'm tired of not having any beat at all so I'm getting a box tuned to 32hz and need some subs. I've heard type r's plenty of times and have two tens in my room. I have never heard the p3's buy have heard good things about them. How do they compare to the sound of the type r? I just need some beat right now and I don't wanna spend more than 130 on my subs. I know either would be a good buy but I can get the p3 for a bit cheaper. Anyway let me know whAt you guys think would be the better choice.

Any one think there is a better quality and sounding sub out there for the price.

Would this work? I know the rms is only 250 rms. The box is tuned to 35 hz (slot ports) and is 2 cuft before displacement. I remember seeing a thread saying the MAW's could take a little more then their rms, but would 600 watts be pushing it? I found a guy selling a pair for $35 each , $87 total shipped to me. I have been wanting to get a pair of MAW's since M5 showed up on the forums, I think I am going to go ahead and buy them and just go easy on the gain. What say you guys, Mark, feel free to leave your expert input

I got a new car and it has 3 speakers in the door. i have 6.5" and tweeter and need 4" should i GULP (so much $$$$) buy the right cross over and the 4" speaker for over $500 or put a 4" and make it my rear. if i make my 4" a rear i will need a new amp. unfortunately I'm looking at $500 eathar way i think, maybe not Will a 3 way blow my mind or 2 way with rear be as good? my specs right now: Head Unit: Alpine W200 Subwoofer: SI 15" Mag Sub Amp: Cadence A7+HC 1200@1Ohm Mids: CDT Eurosport ES-620 Mids Amp: HiFonics Son of Boltar 150x2@4Ohm Battery: Kinetik Power HC1800 Rear Speakers: none Everything is in a box as i plan my setup in new car
