how much would be to get a recone for a re xxx18 d2

Nick can you please confirm enclosure recommendations for the new N2's and N3's. There is no notes in the pinned topics above concerning the new drivers.

Alright guys im new here and don't know if this is the right place for this but i have an old box for 2 15's. Its 10 cu.ft tuned to like 33 hz. Im wanting to get some new Btl N2's. But im not sure if i want to stick to 15's or cut the holes out bigger to hold 2 18's. What do you think i should do? Never had 18's. So Im trying to squeeze the most spl's out of it as i can. Also i will be using my Memphis Mojo 4kw amp.

Can anyone help me with a link or can someone help me design a tuned enclosere for a single Fi BL 15 with a max height of 17 inches? and a max width 36 inches? my first box for my first system.

So I got a 12" Q last week and I LOVE it but my sub cuts out or has alot of background noise and i hooked it directly up to the amp and it plays fine and I am figuring that its the speaker terminal because when i put my finger on the negative it starts to play but when I take my finger off it stops? and In addition the - wire looks charred on the inside connecting to the terminal so my main question is has anyone else had this problem and what would be a good solution?

What do I sacrifice by choosing this option? and can I run 2k to my BL's if I pick this and the other power handling options?

Does the 15" BL need to be in a 4cf enclosure to work well or can it be used in the smallest recommended enclosure which is 3cf without sacrificing anything?

I was wondering if someone could list the parameters on the 2nd gen (UFO style magnet) BTL's for the 18". Im playing around with some Win Isd plots and was wondering how my BTL would compare! Thanks for your time!

I was wondering what would be good to run either the 18" btl n3 or n2, i have the previous style btls which is still are awesome daily subwoofers @ 35hz for me, but i want to move up a little. Is the n3 a good daily subwoofer, and with the option of 5-7 spiders what would that alter, would the normal 5 spider be a better daily/music sub? if someone could answer that for me that be awesome. or is the N2 recommended because i see on smd that the n3 is more of a spl sub, the fs is 51 on n3 , and 34 on a n2. does that mean my box tuning will have too change or no? overall i just want to know if purchasing 2 N3's would be alright for daily purposes/ someday competition with …

right now i have a alpine i got from a guy and i dont know much about it its a alpine mrv-t303 but i want a new one and i was wanting to know which kind would be best a link to one online would be great

I have a 12 " bl and I am about to begin building a new box for it. I want to use the same cut outs posted on here but I want to make the box with the sub facing up and the port facing the back door on my jeep. Does anyone know how to modify the cut out given to make it this way or do I need to make a whole new design?

Hey everyone i have an 05 civic coupe and i am wanting to put a 4 cubic foot box in the trunk. Does anyone know if this is possible and what dimensions i should use. I am going ported with a btl 15 n2. any enclosure help or ideas is really helpful. i am building this myself so nothing too crazy.

Ordering one x12 4 ohm sub today with BP Power option. It will be running in the 320 to 400 watt range. The specs call for a box .6 to 1.1 cuft. Why is there such a range and what is the difference if i built a box at .6 cuft versus building it at 1.1cuft? I have the room to build it to the max dimensions, just would like some more info? How do I figure out exactly what size I need to make it sound great? I listen to mostly older rock, 70's and 80's, but some newer stuff to as well as a little rap if it is a good song.

Could a X10 with the BP power option be put in a larger box than .55cuft sealed? I have a box that is ~.75cuft and another that is ~1.2 cuft. Both sealed. Just curious how/if it would work in one of the larger boxes. With the BP option, what rms can I expect to run in the .55cuft box? And if poss what rms in the larger boxes? Thanks

I am planning on ordering a 12" Q sometime soon. I have the design for a 6th order parallel bandpass enclosure. Tuning is 2.5 cu ft @ 32Hz and 0.590 cu ft @ 74Hz. My Q will have the cooling option so it will have somewhere around 12-1500 rms. I will be powering this by my SAZ-1500d @ 1 ohm. This is going into my 2000 Celica. My question is do you guys think I need the extra spider? The price is not my concern (just $5 difference). But I heard this option takes away from SQ, but I also heard that if you go over rated power on the Q, you need to add an extra spider. IF i do get the extra spider, how big of a difference in the change of SQ? Any input helps

Hi all, I have, what I hope is an easy question.... I have a pair of fully loaded BL 10's, So I am using WinISD to design a box, and I have some missing driver parameters: Pe: ????? ( I was assuming 1000watts ) Le: ????? Z: ????? Any help would be most appreciated! I currently have them housed in a 2.56 cu ft boxed tuned to 28.33 hz that I built for my previous cerwin vega v-max's, and the FI's sound really good in it, I just want to make sure I am not missing anything by not building a spec'd out box. Thanks!

hi there! im planning to purchase an fi q 12 and fi bl 12. i just want to know the shipping weight and shipping box dimension of these two subs. thaks in advance!!!

Hello all, I am wanting to purchase a bl 18, but possibly a q 18. The dimensions of the box i can make are around 16h 32.5w and 22d with the sub facing up. I have a couple of questions, first, does it sound better to have the port on the side of the box or going along the bottom? Secondly, would that be enough space, i calculated it to be around 5 cubes after speaker and port displacement. Lastly, this is going in a celica gt-s hatchback and i was wondering how much room do i need between the back of the car and the front of the box? I think with these measurements i left out like 6 inches between the two. Any help is appreciated.

Any chance I could get approximate T/S Specs for my re-coned subwoofers? The hybrids consist of Memphis 15-MOJO15Q1 (15" Quad 1 Ohm Voice Coils) mated to Fi D2 soft-parts with older style tinsel leads. I purchased these already assembled from a friend but he didn't have any specs on them at all. Any help would be greatly appreciated. Thanks, Charlie Buffalo

I am about to build a box for my incoming BTLs. I reviewed the cut out sheet for 1 BTL that is provided on the forum but was unsure as how a box for 2 BTLs is supposed to look like. I am unfamiliar with how the different dimensions in a ported box affect the performance of the sub so I would appreciate some input. 2-BTL 12 4.9 cubic feet @ 32Hz

I'm looking for someone to build me the box specified in the "BTL Cut sheets" thread. I have the Fully loaded 12" (2010) model BTL sub. I would like to know how much it would cost (both for the box and shipping). And I like to find someone who has made these before and knows what they are doing. If you can show me pics of your previous work that would be great. I would prefer it if you had a PayPal account as well. If there is anything you need to know from me, let me know. Thanks for any replies.

I would dare to say I am pretty cautious. I have a 12" Q dual 2, cooling and all that, and am running a 1000 watt rms mono amp to it. I was just kinda curious as to whether it was possible to blow the sub with that amp or do any damage to it. I have the level a pretty safe setting and make sure to keep the bass equalizer down, but i would like to get a little more out of it. Any insight would be appreciated

I currently have a wall in my car for 6 12s in a bandpass and I'm in the process of upgradeing my subs. My specs on the sealed chambers of my box are 3.69 cubes per side (three chambered box). Just wondering what subs would work best for a daily setup and to compete in bass boxing. Any advice would be helpfull. I'm getting new amps and waiting to get subs before i buy amps

INFORMATION: I own a 2002 pt cruiser. I am going to soon be buying a Fi Q18 and a AQ1200D for my car. I have calculated maximum external volume that the enclosure can be and it is around 8ft^3. I will upload some pictures tomorrow but its dark outside so I can't go take any pics. Two Options: 1. Sealed. Would allow me to downsize the box a bit to around 6ft^3 and give the sub some more breathing room. 2. Ported. I would keep the volume at the max and port it to 28hz like recommended. My only concern is that the space between the Q18 and the rear hatch is 4 inches. I know this will affect the sound but I don't think it will be too big of a problem. So what shoul…

Just yesterday listening to my system, and my sub went out. I checked all the wiring and nothing looks loose. And I don't think I blew it because there was no smoke when it went out. Is there an easy way to tell if it's blown or not? Or if anyone might know what is wrong here, please let me know. The sub is a 12" fully loaded BTL that I bought this summer. Any answers or suggestions are greatly appreciated. And if there's anything else that you need to know, feel free to ask. Thank you.
