CleanSierra Posted March 1, 2014 Report Share Posted March 1, 2014 ^^^Tuning a bandpass box low has NO effect on how low it plays. The size of the sealed chamber affects how low you can play. The ported section affects where you're high end rolloff will occur. Just to clear that up for you OP Edit-I was referring to the 4th order bandpass Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...
Noel989 Posted March 1, 2014 Report Share Posted March 1, 2014 Lol 4th orders don't go low Tell that to Kevin http://www.stevemeadedesigns.com/board/topic/172877-kevosinns-van8-18swest-coast-skyhigh-car-audio-vehicle-kyle-your-vid-is-on-pg51/ Build Log - http://www.stevemead...-cruiser-el-pt/ Link to comment Share on other sites More sharing options...

soBASED Posted March 2, 2014 Author Report Share Posted March 2, 2014 I wouldnt try to tune a 4th low o.O. but im trying to achieve a good response from 25-60 pretty much.. Im willing to pretty much spare my whole trunk for a 6th. If I can design one thatll fit, im doing it. Prob do interchangeable ports if I can. Im gonna change where my ports are and trying to see if I can port each side on each side of the box (left and right) or my rear deck is gonna get in the way. I'll measure my max height tomorrow.

Joe X Posted March 2, 2014 Report Share Posted March 2, 2014 You have a pretty inefficient port on that ported box, twice the port area you have now would still not be too much, a proper port together with forward firing and sealing off would surely give you sizeable gains.

soBASED Posted March 2, 2014 Author Report Share Posted March 2, 2014 Okay thanks for the info. I forgot to mention that for the new box, I would be sealing it off. What kind of port per cubic feet would you recommend for the high tuning chamber?] For the low, I would do a slot port and I know id have more than my current setup Car:- 2013 Honda Accord Sport 6MT - aFe SRI Electrical: - Big 3 w/ Execution Audio 0/1 AWG OFC- Stock Battery Audio: - JBL Power Series 6.5 Comps up front (Running off HU power atm) - JBL Power Series 2-Ways in the rear deck (Running off HU power atm) Subwoofer: - Sundown Audio X-15 - CT Sounds AT1400.1D (@1 ohm) Bedroom: - Yamaha RX-V365 - Pair of Klipsch KG4.2's - 2 E8v3's in a 1.34ft^3 tuned to 30hz - No Amp yet.. - CoolMax ZU900B PSU for amp In my room & previous car:- Amp: Soundstream TX1.1300D @ 4 ohms (520 watts)- T-Line Enclosure tuned to 32hzYouTube : http://www.youtube.c...r8?feature=mhee Link to comment Share on other sites More sharing options...
soBASED Posted March 2, 2014 Author Report Share Posted March 2, 2014 So I measured my trunk again, and because the rear deck comes down near the seat more, the box will have to be behind that (unless sub faces up inside the box, ported on bottom and top) but my dimmensions are 17.75"H x 30.5"W x 30"D. I came up with a design that works (but dont know if its actually good). Chamber 1 is 3.7ft^3 tuned to 28hz.(15.37^2 inches per foot) Chamber 2 is 1.39ft^3 tuned to 74hz.(58.45^2 inches per foot) This is with the low pass set at 80hz and forgot to add the SSF. The sub will be facing one side of the box and ported on each side firing into the cabin, sealed off from the trunk.

ChrispyShimp Posted March 3, 2014 Report Share Posted March 3, 2014 How did you get winISD .50? I have the .44 and that's the only one I found. Knowledge is the greatest tool in any garage. It's also the most priceless, and most easily shared. Here's my latest build. http://www.stevemeadedesigns.com/board/topic/181273-89-c1500-build-log/ Link to comment Share on other sites More sharing options...

James Feaster Posted May 9, 2014 Report Share Posted May 9, 2014 I know this is probably a noob question but how do you tune the fourth order box? Link to comment Share on other sites More sharing options...
