when u enter the box design posted on the forums for the ssd into the re box calculator i get a tune of 30 hz ??? is this right cuz i need to change the dimensions a bit for it to work for me i making a rear center console for a 10 ssd. and also i can only seem to get 17" of port area not the 27 i assume i need will this be a problum ??? and also i will not have a L port just a straight slot. any suggestions or help would be appreciated thx

How big of box should i use for 2 15'' Bl's? (Space is NOT a limiting factor). Also i want to use 6 inch round ports tuned to 30-35 hz. how many would i need?

Building a wall for 2 x 18" BL's in my Ford Focus ZX4, as it stands now we've got 10.5 cubes per sub, my questions is how much port do i need? how much port surface area etc. etc. ????? Any help would be greatly appreciated. Thanks. Dan Soundmekanix SPL design Team

I havnt heard back from you yet, did the recone kits get sent out cause i really need them by the weekend, and you told me they would be here in time. If you can send me the tracking info please. Thanks: Les Rutherford

just ordered my bl's and sketching up a box, could i get a little advice if this box will do

I will be running 2-18'' BTL's off of 2-MTX TE4001D's. I would like to know if this power setup is good for what I need to run my amps. Yollew top for the starter with a 200 amp alternator, 200 amp isolator, and 2 yellow tops in the rear for the sub amps. How would I wire the 2 yellow tops in the rear. + to + and - to - ? Ground each battery or only 1? Any help with this would be great and where and what battery,alternator,or isolator I should use? And what is the Big 3? Thanks Fi buddies...

I have a toyota ex cab truck and I was wanting to know what is the biggest sub set up I can fit in the back? The space in the back is 19'' deep X 22'' tall X and 53'' wide. I want to do a ported box with either 2 Q18's or 2 Q15's. Given this amount of space what do you think I could fit back there? -Alex

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

Hey guys. Im about to pull the trigger on a 12" SSD. My question before I do is can I reverse mount the sub? The space is kind of tight for the setup im trying to achieve and this would be my best option. Also I have a Diamond Audio amp already on hand. It can push 800rms @ 2 ohm and 1200rms @ 1ohm. Which would be my best option.? I was thinking of getting the 12" Q if it is a better option but was hoping to go with the SSD. Im already pushing 300rms to my DLS comp. up front. from a seperate amp. Im looking for an LSQ setup. Sorry for the winded post and thousand questions. Thanks for your help......

Hi, I have a Fi BL 15 of 1000 Watt rms 2+2 ohm. I'd like to create a ported box too much little as possible. I'd like to place the box in my car as in the picture. Can I have a project please? Thanks a lot

I am not entirely sure about box dimensions and all. I want forward facing subs. I know 15's will work, but wonder if I could manage an 18. These are going in the bed of my truck with a fiberglass flat shell on top. I am pretty sure the depth of the bed of the truck is 20 or 21". Would I be able to build a box that will fit in this for 18's, or is it way to tight?

I believe I will be running this amp at 1ohm to my dual 2 ohm sub. Will this sub handle what is said to be 1500w RMS from the SAZ (which I have heard is under rated)? I am not planning to pin the gain or anything, I just do not want to blow the 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...

ok so i have built alot of enclosures in my day but it has been about 4 years or so I have a mx15 in my truck right now with a 6" round port and its tuned to 32 hz sounds great i am super happy with it ok now onto the project I am helping a friend design a box for his car and a wedge style box is optimal to save the limited space that he has I will be using a BL12 and we will be making a ported box for it but the standard slot port wont work well for his application so we are opting towards a round port now here is where the issue arises I am unsure what size port i should be running single 6" or single 4" or possibly something else the enclosure we r shooting for is a f…

I was wondering if any one knows the true RMS rating for the Earthquake PHD5000, Kicker 1200.1, Massive audio P3000.1, AUTOTEK MM4000D, MA AUDIO HK802SX, Orion 2100, and Hifonics bxi2006d or Hifonics bxi1606d? I am just trying to figure out witch amps to go with when I run my stereo. If any has tested any of these amps please let me know. Also I would like to know if any one has ran one 12" BTL daily in a trunked car and had it metered to music? If so please post your scores on here along with pics of your installs or your car getting the score. Once I get mine I will let you know what it does with a bunch of different amps. Hopefully I will have it posted on here by next…

Im looking at buying a Fi BL 15, im going to run it off a 1700 rms amp. i dont know what opions should i get. i was looking at the 4" coil. i think that makes it 1500 watts rms i heard but im still undecided. little more opinons would be helpful.

What wiring Options do I have with Dual D1 Coils for 1 and 2 subs need all the wiring possibilities. Thanks in advance

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

alright guys i need some help on choosing a amp for my sub. i was thinking of getting a crunch 3000 pro 3000 watt rmms at one ohm for 439.00 is this a good amp or should i look in a different direction. i fogot to say the btl is fully loaded

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

So is a 3.9^3 box too big for a single Btl N2 12" on a Saz-2500? I know that the spec sheets say 1.75-2.5 cubed. It was professionally designed and the person who designed it says that it still falls within the thermal/mechanical specs for this sub, so they dont understand why i am questioning its size. I don't want to damage the sub with over excursion though, so any input would be great. Thanks!

Hello Im building a box soon for a Fi BTL N2 15, and its going in a honda accord. But im tired of thinking that all the sound is in the trunk, so i was planning on removing the backseats, and build the box so the sub and the port would point forwards. (So the sub and port would be right behind where the seatback's should have been and the box inside the trunk. (kinda like this: What do you guys think? Would i get more sound pressure in the front seats this way? Or would it be better with the sub in the trunk and maybe port up the parcel shelf? Any ideas what would give me most pressure in the frontseats? Thanks alot

Hallo from greece. I want to know how many litr do i want for two Q 15" to play deep bass at 32hz???What power RMS can handle 2 of them together??? Thanks.

Im currently using the RE Enclosure calculator (http://www.reaudio.com/speaker_box/LPort_Box_Calc.html) and after putting in the dimensions I can fit in my trunk and Im playing around with port size and what not and I was curious, the "tech" section on the Fi site says the recommended tuning is 33hz, I can only get my box to fit if I tune it around 34hz, is this an issue? would it be better to be lower than ideal if you cant get the ideal 33hz like 32hz instead... Or am I not even gonna notice? Also, again refering to the "tech" section, for the 10s it recommends 15 square inches of vent per cubic foot of air space, is it a major issue if I can only work around 12 square …

what would be a good box for 2 15" bl series subs.
