how much port area should use for a 6cube box with pvc ports? is 4 4" ports enough?

In the near future I am going to get 2 12" SSDs with copper coil option and a sundown SAZ1500D. For the box I was planning on having the subs hit up and the port back but I'm also taking any opinions on that. Also I might make a sealed box as well for these. I'm going for overall sound quality and just wanted to know what you guys think about the whole thing. Thanks.

I ordered an SSD recone yesterday and there is no option for integrated leads on the site. I added in the special instructions that I want them. Can you please include integrated leads and charge me for them?

I have a 2 channel amp and im tryin to see if I should get a dual 2ohm voice coil or dual 4ohm. How will i be able to wire the subs to get a 2 ohm load to the amp without having both subs connected to eachother

When i Had a problem about a month ago my Sub would make a burp sound once in a while and i was wondering if that damages the Sub

I received my Fi Q15 yesterday!! I ordered it with the BP option and a Red dustcap to match my car. This sub looks amazing!! The build quality of this Fi product is better than that of other brands. I was really impressed with the multi stranded woven tinsel leads. I cant wait to install it this weekend. I am finishing up my box (4cf @ 30hz.) and will be running a Cadence iA7 in a 07' Chrysler 300C. I'll make sure to post pics when completed. Thanks to everyone who helped me make my decision and especially to Scott and the crew @ Fi!!!

Im In The Process Of Building New Box For My 87 Mustang. It Will Be For 2 BTLS's Around 8 Cubes Net. The Anticipation Was Killing Me So I just Went Ahead And Threw My Old Box Where The Passanger Seat Was to see how it performed on my SAZ-3000D At first i was amazed. Then about after 15 min. of Slamming it it wasnt as loud anymore and the BTL wasnt Able To Handle the Amp Half Way (Gain All Way Down) It was Already Reaching Its Limits And Bottoming Out. so i was pretty bumed as it sounded the same if not less than 2 memphis 12" subs. so i was looking making sure all the connections were tight and secure, and i decided to take my DMM and meassure the Voltage off the battery…

Right now someone figured out my box was 3.8 cubes at 31hz after disp. With that, a 15" BTL with no options and a Hifonics BXi2006D I hit a 141.7. That was my best score. I am trying to hit a 150 with this one sub. I am getting alot of different inputs on box sizes to use...and I know hitting a certain score has MANY varibles...but I figured to start off..a better box could help a good bit. It is in an extended cab truck, port up and sub up. I want pretty much SPL, but it is my DD. With a new box, I am still going to be listening to music. So I figured who better to come to for box advice then the people who make the sub.

I'm not entirely familiar with Fi. What I've read however is that they are a high quality semi custom subwoofer. I've noticed the watt ratings are very high for each aside from the IB3. I realize the Q series will probably not fit behind my bench. I have a 2003 f150 regular cab. That leaves me with the SSD our the IB3. I will only push 600 rms to each so 1200 total. JL HD1200.1 The box will be custom made. I have close to 12.5" of room at the floor. One thing that is holding me back its the fact I'm reading allot of revive posts in the forum. Do these subwoofers experience problems or break frequently? Any input would be greatly appreciated and rewarded with fond 'nonsex…

hey guys i know this is a spl sub, but alot of you folks do use them for daily drivers..how do you like them? i really want to try a few but im worried that they wont sound right..and by that i mean im comming listening to w7's for 6 years..and i know after that many years on 1 sub your ears get accustomed to them..so are the btl's something i listen to all kinds of music like rap and rock daily and still enjoy or am i barking up the wrong tree and should maybe look at bl's? also i have a side question, say you have a 12'' spl sub and a 18'' of the same spl sub, would the 12 sound better and be tighter cause its smaller or no truth to that?

I ordered my 12" X series sub July 15th. It says on the website it will take 3-7 business days to build, then it will be shipped. Today is the 21st business day! I emailed a while ago and received a reply on Aug 4th that the subs are currently taking 10-15 days to build and that my sub should be shipped out by the 5th. I emailed again on the 10th when I still hadn't gotten an update on my shipping notice and still haven't gotten a reply back. What is going on? If you are having problems and need to revise the ship dates, at least let your customers know. Me having to make a post and ask isn't very good business.

as i had anticipated. Of course i still need to upgrade to the big 3, and running a bxi1606d at 1ohm. It's in my 99 Denali and i made the box to 7.5 cu ft tuned to 32 hz. I double bffled all the walls to a total of 1.5 inch thick. Do i need to upgrade to 0 gauge wiring? A bigger amp? I noticed that the BTL was SUPER stiff! Mayb i need to push 3000w to it instead 1600

I sent an email to Fi Audio about a week or go and i got no reply. I sent in an order for a FI Q12 on June 23rd. Then i sent an email on the 24th requesting some information on the enclosure. Please PM me or reply to my email. Thanks -Mike

Ive had my 18q since november I never posted here before but since this the Fi forum id thought id post these here its on a hifonics BXI 1606 http://s27.photobucket.com/albums/c183/Loc...nt=MOV00877.flv http://s27.photobucket.com/albums/c183/Loc...nt=MOV00876.flv http://s27.photobucket.com/albums/c183/Loc...nt=MOV00875.flv http://s27.photobucket.com/albums/c183/Loc...nt=MOV00873.flv http://img174.imageshack.us/img174/1909/dsc00879ay4.jpg box is 6.5 cubes internal tuned to 33hz 96 sq inches of port

I ordered a sub With the SPL Option. Someone told me that you could play the sub really loud for short periods of time and it wasnt for just driving around with it loud. But i am now finding out that it isnt like that at all i was wondering if anyone could help explain too me what SPL is.?

Fi is shown in another featured vehicle in the latest issue of Car Audio and Electronics! This time in a SQ car. Yes its mine

Anyone have any experience with the groundpounders??????

Using 2 sundown 1500d's. Strapped. 2ohm for daily, and .5 for comps. I'd also like to build another box and possibly compete. Wanting loud with decent sq. Will be going in a hatchback. I have 8ish cubes. I'll be using recommended enclosures.

The other day I whiped together a box for my Q10, 14x14x12, 3/4in mdf, comes out to around .9 cubes. I screwed up on one of the cuts so i just siliconed the chit out of it. So i have it in my truck now, pushed by 900 kenwood watts rms and there is a clicking noise coming from the sub. Not so noticeable on the lower notes or in rock songs, but it really makes me mad. I pushed on the sub, no scratchy sound, i put the coils on a DMM, both at .8 ohms. WTF! I also tried it free air a little and the noise is louder let. I read on another forum to check my spider for rub marks from tensel slap, and i couldn't find anything. Any ideas? Am i doing something wrong?

This time its in daylight and is much shorter because people complained on those points last time haha Although this time im driving and its not that easy to control the car and film while having that much bass ripping though the steering wheel haha Update on sub, its loud and insane, ive done several upgrades such as cleaned everything up, the big 3 and moved things around and I seriously could not believe what a massive differnce the big 3 made on how loud this sub goes! edit* oh and please rate and comment if you like, 5* would be nice

Any update on the Blue Print Audio home theater line of subs?

Hello everyone, im new to Fi and have decided to try out one of their drivers, however i need some help. I just recently ordered a 12 BL D2 w/ cooling on the 18th and went down to a local shop where im getting the box made eventually and showed the guy the BL's specs which i had written down so he could get an idea of what he would be building. He took a look at the driver's FS of 37.8hz and thought i was crazy for getting a sub with such a high FS...saying it would suffer in lower frequencies. So i starting thinking perhaps i should of got a Q instead of a BL. Ive got a Nine.1 @ 1200 rms to throw at it for Daily Driving...not SPL comp/burping, etc, just a street beater …

i have 2 x15inch fi btl on a Lanzar OPTI 6000D, do you guys think im under powering them??? they knock, but i fell like everything i throw at them, they handle with ease, so im thinking of getting a additional Lanzar OPTI 6000D to pound extra hard.... lets me know what you guys suggest?? or should i go with different amps?? Just a thought.

Let me know which is better, and if i can push them to max power with 3 2000 watt amps (1 for each), please let me know if that will work....THANKS!!

LOVE THIS SUB!
