Bakerman Posted March 26, 2011 Report Share Posted March 26, 2011 Okay, this is for you guys who have been doing this for years, experience every sub, and every kind of box. I've ordered two FI BTL N2 12" subs. The website suggest 1.7cu feet to 2.5cu feet of space, tuned at 32hz, with 12 to 16sq" of port per cubic foot. On the several boxes I've built, I've always maxxxed out the cubic feet as much as possible. Now I have a Focus, and space is limited. I am trying to build a box tuned low, so I need alot of cubic feet. But, the most I can possibly get w/out having to take off panels and still have room for xtra batts and my two amps is 3.43cu feet tuned at 32.16hz with 12.76sq" of port per cubic foot. Now, I'm not worried about the tuning or port area, but I am a little worried about the cubic ft of the box. I know it is in the parameters set by the specs, just barely, but I am worried it will not achieve the deep, low bass I desire. Could someone help me out and let me know if you would recomend doing this, or if you would go a little bigger. I can achieve just a slight more bit of area, possible 4.5cu ft at the most, but then I would have to get creative with mounting the two AQ2200's and the AQ4x90. Thanks in advanced you guys...i always appreciate your knowledge and help. Quote Link to comment Share on other sites More sharing options...
hdorre Posted March 26, 2011 Report Share Posted March 26, 2011 I don't see why it wouldn't get low (especially with that port)...itll probably just be peaky Quote On 5/8/2011 at 7:38 PM, Kranny said: On 5/8/2011 at 7:35 PM, 'Maxim' said: It hurts me inside when I read stuff like this and remember you're 15 LMFAO so true Mitsubishi 3000GT (Old Build) Headunit: Pioneer 80PRS Frontstage: (2) McLaren Audio MLT-2 Tweeters & (4) PRV Audio MR Series Neo 6.5" Mids Substage: 4 15" Hybrid Subs - Tantric Motors & Sundown Softies Amps: Banda 2.4D Amp (Tweets), American Bass VFL 350.4 (Mids), and (2) Ampere 3800s Electrical :Singer 260A Alt & JY Power Lithium 2005 Chevy Colorado Ext Cab Headunit: Pioneer 80PRS Frontstage: 4 PRV 700Ti Tweets & 6 10" Delta Mids on 3000wrms Substage: 6 Fi BTL 18s in a 4th Order Walkthrough on 3 Wolfram 4500s Electrical: Singer "390" and JY Power My Official Feedback Thread Link to comment Share on other sites More sharing options...

hdorre Posted March 26, 2011 Report Share Posted March 26, 2011 By peaky, I mean that some frequencies will be a lot "louder" than others.

Bakerman Posted March 29, 2011 Author Report Share Posted March 29, 2011 (edited) ^^^any way of knowing which frequencies, or is it one of those things you just have to play around with and test out?

Freshman6969 Posted March 31, 2011 Report Share Posted March 31, 2011 try aero ports? thats my suggestion Quote Legal TL scores145.6 on the dash sealed up in the low 40hz area with the port out145.5 on the dash sealed up @30hz with the port inless then 1k clamped on a 3.5k! Why would you EVER WANT flex?huh?...flex is what can make the lows lower and more air being pushed correct?

Bakerman Posted March 31, 2011 Author Report Share Posted March 31, 2011 try aero ports? thats my suggestion Didn't really have the room...i'd need to go external to get the tuning i'd need, and i just don't have the clearance for it.

MrSkippyJ Posted March 31, 2011 Report Share Posted March 31, 2011 ^^^any way of knowing which frequencies, or is it one of those things you just have to play around with and test out? play around and test out. my box turned out to be VERY peaky (it was a sealed box originally for a single JL 12 then adapted to fit a DC 12" level 2 and ported). WHen I made the trip to Ricks shop, we TL'd my set up and it peaked at about 51hz. SMall box and small port, sounds good though!
