Karkov Posted August 30, 2013 Report Share Posted August 30, 2013 I have done sealed in the past for that application but I am not saying that is best. 2007 Chevy Tahoe (SOLD) 12 ~ FI Audio X series 10" w/BP option 2 ~ DC Audio 5.0K @0.67 3 ~ DC Audio 5.0K @1.0 2 ~ PPI 3 way sets (not installed yet) 1 ~ RF T400-4, 1 ~ RF T600-2, 1 ~ RF T600-4 4 ~ CT Sounds 5.25" Strato comps (rear fill only) 1 ~ XS Power D4800 1 ~ XS Power D3400 8 ~ XS Power XP3000 160 stock alt, Mechman 370 Elite, 185 DC Power 320+ Sq.

Krakin Posted August 30, 2013 Report Share Posted August 30, 2013 You build an enclosure that goes for your subs. Whether the enclosure is for spl or quality, doesn't matter. Krakin's Home Dipole Project http://www.stevemeadedesigns.com/board/topic/186153-krakins-dipole-project-new-reciever-in-rockford-science/#entry2772370 Krakin, are you some sort of mad scientist? I would have replied earlier, but I was measuring the output of my amp with a yardstick . . . What you hear is not the air pressure variation in itself but what has drawn your attention in the two streams of superimposed air pressure variations at your eardrums An acoustic event has dimensions of Time, Tone, Loudness and Space Everyone learns to render the 3-dimensional localization of sound based on the individual shape of their ears, thus no formula can achieve a definite effect for every listener.

Dosent matter? They can be ported of sealed, and then there are all different kinds of enclosures? i have a feeling it does matter.. Link to comment Share on other sites More sharing options...
Krakin Posted August 30, 2013 Report Share Posted August 30, 2013 You design enclosures for speakers based off of their Thiele/Small parameters. If said parameters do not fit the criteria to go in a sealed enclosure then you are going to have a bad time if you throw it in one.

TeamHirshAudio Posted August 31, 2013 Author Report Share Posted August 31, 2013 Well i know that.. im just asking what kind of enclosures do people feel have the best sound quality. 4th order, 6th order, and so on. Link to comment Share on other sites More sharing options...

White Lightning Posted August 31, 2013 Report Share Posted August 31, 2013 Thinking of running 3 sundown sa-8s on 2k, any suggestions on what type of enclosure id be best off with for sq? 4th order, regular box, or what? Any suggestions are apprrciated! Thanks!Don't get me wrong ... I really like the Sundown products, but I would not use them for a Sound Quality setup ... And I really enjoy my flat response, ported and tuned enclosure (24 htz) for my Sound Quality setup ... ... and if you are looking into true Sound Quality ... 2k is not necessarily needed for a responsive 50 htz and below setup ... But whatever sub amplifier you use, it needs to be really dynamic and have alot of headroom capabilities ...

CleanSierra Posted August 31, 2013 Report Share Posted August 31, 2013 To kind of shed some light for you OP, briefly: A 4th order bandpass has a steeper frequency rolloff, ie potentially less useable bandwidth. A 6th, same story. A typical vented enclosure has about a 12 dB/octave rolloff and a 4th will have a rolloff around 24 db/octave. So you can get some GREAT output in a more narrow bandwidth from using a 4th order bandpass enclosure. Finding a sub that fits the parameters for a sealed box will provide the most linear flat response, but in theory you can get the extra 3 db benefit from a vented cabinet. CablGuy(Randal) is very knowledgeable about SQ, therefore listen and take notes. Seriously, write it down and commit it to memory. He has a lovely isobaric setup that I've heard does a marvelous job at reproducing sound with deadly accuracy and clarity. I hope to sit in his truck one day with to soak it in. Vented enclosures can give you great range if designed well and built properly. Having good cone control and an enclosure that can perform IN the vehicle is very important. 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...
