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

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"

I was wondering if the specs are close enough between the two subs , that can I use my old box (really not old, 3 months) to house my new Fi 18 inch BTL Sub.

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...

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 …

im about to switch to port tubes instead of slot ports and i was wondering if i have 2 18" fi q's how many 6" diameter ports would i need. i have the box set up into two chambers at 7.1 cubes each. i was wanting to tune the box around 31-33 hz. i didn't know if i should use 2 ports per chamber or just one and what the exact lengthe should be.....ive used most calculators and they are telling me with 1 6" port in a 7.1 cube box the length should only have to be 6 inches, which doesnt seem right b/c i was thinkin more like 15-16 inches. shoot me some info thanks

does flat wind coil and bp power add to a 12" ssd? how about bp power on a 12" Q? just thinking about future upgrades. thanks.

I was wondering if 6.75ft3 net volume at 32hz is good for 4 FI BL 12's in a ported enclosure with about 6,000 watts of power?? 6.75ft3 net volume, 32hz tuning.

ill be ordering the 12" ssd's soon and temporarily they will be going in a prefab (i hate prefab) dual twelve box with the port in the middle. 2cuft per woofer. when i put my other woofers in there they were loud as f**k but when i played a song like bass mechanik moonstone that has a 20hz bassline they bottomed out and almost broke the voice coil. heres my dilemma i have been seing a lot of people use the boxes that are similar to the box i have exept the port isnt in the middle of the woofers its on the side.ex: http://subwoofertools.com/forum/ported-box...mp;Fs=&CE=0 all of the vids ive seen they either burp the woofers or they play some crap from jeezy, never any…

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

Im getting 1 18'' fi.btl fully loaded and my enclosure is going to be 6.3 cuft. (After all displacements) 3/4mdf tuned to 34hz. But as far as the port can you please tell me how long,tall,wide,etc. it should be for best hairtricks,loud bass at high notes,and the best low bass I can get (Since being tuned to 34hz.) without port noise. One more thing as far as the enclosure should I have the top and bottom of the enclosure double baffled or triple baffled or the whole enclosure double or triple baffled or what? Please help as much as you can I really appreciate it!!! Thanks guys

Whaaat happened? you guys just ruined my next setup :(:( will there be any 15 bls coming?

Right now I'm in the middle of my build with 2 18" BL's with a Trutech Hammer H1 per sub in a 16cuft wall tuned to 30hz. After this I'm pondering changing to two BTL 18's with a DDZ1. Just wondering would it be worth it in terms of being a major leap over the BL's and the Hammers ?

Anyone know the total weight of the 12 SSD? Or even just the magnet weight? thanks

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

Can anyone design me a box for 2 12'' fi btls? I have a blazer i would like it tuned around 30 hz any suggestions?

hello guys I have two Q15's in a dual chambered slot port box tuned to 27hz @ 8cuft. My question is will it be better to build another enclosure where the drivers share the same chamber? And should I double baffle it? Also, what about bracing? How do I go about doing it? I tuned low because I want the ground pounding bass that you get from the lows as I don't really play anything above 45hz. Thanks.

hey guys .. im looking at building my own enclosure for my BTL 18" and was wondering whats the minimum cubic feet as i have a limited area to work with Thanks

I am looking for sound quality mostly, not worried about if the bass rattles my car apart. If I go sealed would it be terrible if I went prefab from online? and if I went ported I am thinkin about 2 cubes at 30 or 32 hz. how big of a difference would trupan-lite over mdf make? thanks all

I have two fi q 15 w/bp power that I need to ship in for recones. could you please send me the info that I need to go about doing this? do I pay before or after they have been fixed? thanks
