I have two ssd 15 inch. im building my own ported box. i cant find any dimensions. i want to have a single box, technically two separate boxes inside with a divider. can anyone help me with some dimensions

I am going to use either the Q's or bl's , the box is going to be ported useing psp flare ports 4"x 17" four of them at this length. is this going to be enough room and are the amount of ports correct to tune this box to 28hz.. this is for a daily driver I listen mostly to rap and R&b. If this doesn't sound right could some one give me some direction, this is my first box build and i want to get it right. any help would be graetly appreciated thanks.

I am getting 2 12" Fi X in a trade and want to know the t/s specs there are none on the website. All I know about them is they are 300w rms and D4. I thought to myself they were perfect for HT. Wire them series parallel and final load of 4 ohms, BASH500 does 500w @ 4 ohms. So, I just need to know some specs so I can figure out what kinda box to put them in. I want to put them in a tline since space isn't really an issue Thank you for your help.

I've been playing with my max dimensions and the biggest/best box I can come up with will be 12.33cu ft w/ 192.5sq in of port tuned to 32hz. I would like 13-14cu ft but the only way I can get any more box volume will be to shrink the port. Will these specs do okay for a daily driver that does part time competitions? Primarily it is a ground pounder. Thanks

My buddy is trying to put a 18" fi ssd fully loaded in the back of his eagle summit van.. He has about 1200 watt rms of power to run the sub.. There is two different set of max dimensions we can use ( it all depends on how tall the box will actually be. The first set is a tall narrow box and our max dimensions are 27 1/4 tall X 39 wide X 15 Deep. And the other set is 20 1/2 deep X 39 wide X 21 tall. Any help would be wonderful... Would really like start build on box as soon as we can.. Also I would like it ported wit a tune right around 32 hz. And I not sure wat would sound best wit the speaker direction and port direction so any advice is wonderful.

any box builders out there wondering how much you charge for a box for 2 18 BTL FL, flared port, 13ply birch, 5-6 cu a piece shared chamber. dimensions would be 52 width x 20 depth x 25 height that would be my max dimensions give or take a few in. Another guy (Ryan Wallace aka Belunt from CAJ.com) was suppose to build me a box, but i cant get in touch with him now, and im trying to get a refund. but someone let me know something. thanks

what's the best enclosure volume for single 18btl powered by saz3000d?

I ordered 1 18" Fi SSD. I plan on getting another one soon. And was wondering what kind of amp I should get? I went ahead an got the dual 2 ohm voice coils on the amp. I'm looking for something cheap. Possibly well under $200? Currently I have a MA audio 18" 1100 watt amp with a legacy audio 2000 watt amp and it hits hard but it doesn't have near the quality I'm looking for. With the new SSD I'm looking to run either a 1ohm or 2 ohm config. Not sure yet what to do. Any ideas? I'm also wanting to run the SSD at atleast 650wrms 800 would be perfect.

Hey guys and gals, I have been slammed at work with all our new server upgrades and 32 new users that we hired, and I am the only network admin for a company with 55 inhouse users, 2 servers, and 21 remote users(<---- the worse part, remote users).

hello i was just wondering if i could get an update on my sub...i sent it in last month and got a reply that it was in....and then replied back to fr...and haven't heard since thanks....josh

Lookin for info on the q18, you guys recommend 4 to 8 cubes for the 18 sealed. With ~1kw each would 5 cubes each be acceptable? I'm looking for them to carry into the upper range a little more so I'm thinking a smaller box would fit that. Toying with the idea of doing 3 of them sealed in my ext cab truck on a saz3000 for a bassrace/daily ground pounding application. I'm currently running an hdc318 on 2200w and it gets downright loud and I like the upper end response as well as the lows it gets, just looking to try something different. Always wanted to try a large sealed application that got loud both bottom and top end, just not sure if the q18 will do it, which is …

I'm probably going to order my Fi SSD 12in this Friday, and was wondering which coil to go with. It will be hooked up to a Kicker ZX750.1. And I read somewhere, that these can be somewhere between 900-950 watts RMS at 2 ohms. So would the Flatwind Coil be the best to go with.

I have made up plans for a 6cu ft box, after port and displacement. The port would be 4" Wide and tuned about in between 33 and 34hz. If i made the port 5" wide, it would take the box all the way down to 5.1 cu ft or so to be tuned to 34. The port would be 21.5 in tall. It just seems to me that 4" is small, but then again thats a lot of box volume to take up. I'm really hoping i'm just more worried than i should be about port size, and the 6 cu ft will work out. Any suggestions?

i want to recone my 18 to a 10, any body know who i can contact for one or a price?

I want to build a sealed box 25X15X17 for a Q15 is that big enough? Should I add any bracing, if so where Thanks Jacob

i just purshased 2 18" btls.i have 4 cf for each 8 cf gross for both.i want to tune the box to 36hz .can some one tell me how many square inches of port opening and the depth ofthe port that i need.thanks

Hey I'm going to buy 2, 12" BL's and I was wondering what amp you guys would recommend to get the most out of these subs...

Currently have a 12" BTL (D2, loaded, daily) powered by 2500D. Box is 2.5cuft @ 32Hz (after displacement). External dimensions 27" x 18" x 16". Port is 14.5" x 2.5" x 40"? (forget, used subwoofertool.com few years back) Would like to get a bit more out of the lows. They hit good as it is now, even down to 25Hz, but they could probably be better. Just wondering what I would need to do to make another box that specializes in the bottom end more. Smaller box? Larger port?..etc. Was thinking, maybe 28-30Hz tune? Maximum dimensions: 31" x 18" x 16"
