JesseyMclame Posted October 1, 2013 Report Share Posted October 1, 2013 So, as the title says, I'd like to know a little bit about the differences between both boxes, and potentially what one would benefit me more. I've got a 2000 ex cab S-10, big 3, all 1/0, deka intimidator up front, and stinger spv70 rear and a DC 2.0k. So, I have a 8^3ft box tuned to 34hz right now, that's housing 2 Fi BL 15's. Thing is, only one of them works. The top plate shifted on the other one, so it's just kinda in there, taking up displacement.. So I've ony got 1 15 playing currently. And honestly, for what it is, it gets down pretty well. A buddy of mine suggested a 4th order for just the 1 working 15. I don't really know much about 4th orders, their design, how they work, and so on. I'm really just looking for more output, and more low end. If anyone can help me open my eyes a bit, that'd be great. Thank you ! Current setup in my 96 Hoe Hu - Pioneer DEH-80prs. Amps - (4) Crossfire C5 1700D's, MTX Thunder 5604(mids), PPI Art 300.2 (tweets) Batts - 4 91ah rear batts, 50ah batt up front.

ToNasty Posted October 1, 2013 Report Share Posted October 1, 2013 wider bandwith. depending on ratio , it could also have more output. thats just my understanding ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...
Krakin Posted October 1, 2013 Report Share Posted October 1, 2013 4th order bandpass enclosures are more for drivers that are more equipped for sealed enclosures. sealed-4th order ported-6th order A "bandpass" is an enclosure that has natural acoustic filters for low-end roll-off and high-end roll-off. A ported enclosure only filters as a high-pass. 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.

JesseyMclame Posted October 1, 2013 Author Report Share Posted October 1, 2013 wider bandwith. depending on ratio , it could also have more output. thats just my understanding Hmm so it pretty much would be more of a musical box ? 4th order bandpass enclosures are more for drivers that are more equipped for sealed enclosures. sealed-4th order ported-6th order A "bandpass" is an enclosure that has natural acoustic filters for low-end roll-off and high-end roll-off. A ported enclosure only filters as a high-pass. Would you be able to explain to me what a 6th order is and the advantages and disadvantages are of it ? Also, my goal with this 15 is to be as loud as I can with what I have on music. Current setup in my 96 Hoe Hu - Pioneer DEH-80prs.

ToNasty Posted October 1, 2013 Report Share Posted October 1, 2013 6th order is basicaly 2 ported boxes in 1, one tuned low and one tuned high. but there is a few differant kinds of 6th orders and when it comes to those i now nothing. ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...
SnowDrifter Posted October 1, 2013 Report Share Posted October 1, 2013 6th order is a low tuned ported box firing into a higher tuned box. Think like a 4th, but instead of having a sealed side it has a ported sideAdvantage: Can be louder than ported, can have a HUGE bandwidthDisadvantage: They are big. 2-3x the size of a typical ported box. Need some tuning to get right. More sensitive to design flaws.

Krakin Posted October 2, 2013 Report Share Posted October 2, 2013 4th order bandpass boxes are not recommended for high excursions woofers. Would not do if it was me. I don't see why a 4th would car about xmax? Isobaric it would matter. But to quote TaylorFade The "order" of a box actually refers to the rolloff. It has nothing to do with the alignment really. Like a 4th order crossover rolls off at 24db per octave, a "4th order bandpass" rolls off at 12db per octave below tuning AND above (hence the 4th order designation). Just as an aside... a regular ol' ported box is actually a 4th order. A 4th is more accurately a "single reflex bandpass".

Soccerballzs Posted October 2, 2013 Report Share Posted October 2, 2013 Why use a high excursion sub to fire into a sealed box waste of power. http://www.stevemeadedesigns.com/board/garage/vehicle/2438-jeep-commander/I Pioneer P99RSAmpere 38002-Ampere 125/44-6.5 inch Hertz HSK XL Mids4-8 inch JL Audio ZR Midwoofer 2-5.25 Satori Mids2-Morel Tweeters, 2 Hertz Milles 3 inch on A pillars2-Hertz Silk tweeters DC Audio Level 5/12 Skyhigh Wire Mechman 320 XS Power D3100MO Funniest Thread of the Year 2013: http://www.stevemead...dy-being-a-pos/ Link to comment Share on other sites More sharing options...
