White Lightning Posted August 31, 2013 Report Share Posted August 31, 2013 SA 8 subs been know´n for working good in ported boxes.ok brother ... please let me explain. I never said that Sundown products are not good for Sound Quality, it's just the I would never use them in a SQ vehicle (personal preference only). Now the reason That I said this is for our pure Sound Quality applications where major volume is not an issue, Meaning tighter suspensions would not produce those very delicate frequiency responses like the drivers we use will ... For an every day musical sub driver, Yes, I think they are great and would recommend them if I was not sopnsored. Most subs (like the SAs) have really tight suspension setups and that makes it very hard for a dynamic amplifier to reproduce those those stand up bass instruments you very commonly hear in Sound Quality music and when time aligned correctly ... make you have a sence of "Up front and on the dash" bass response ... Honnestly ... if Cerwin Vega still made the "origional" strokers ... That's all I would use for Sound Quality and SPL ...

john253a Posted August 31, 2013 Report Share Posted August 31, 2013 If you want to run the sa8 1.8 net 25-28sq" of port 32-33flat And enjoy However Another sundown sub to look is the x for a more low end monster I love my sa8 and they slam for what they are But you could do a 2 fiq10 or 12's sealed Even a single q15 sealed in same net Just get the qts option Other wise a single q12 ported @28-30hz will do the job nicely And save some coin on the power Link to comment Share on other sites More sharing options...
TeamHirshAudio Posted August 31, 2013 Author Report Share Posted August 31, 2013 I really dont know what driver would be the best I am very new to SQ and have a lot to learn with all that what works with what stuff. I dont want to start a VS. thread here but I know some stuff works better with certain stuff. Could I have some examples of some SQ set ups out there? Like how many drivers, what brand and what amplifier? Thanks for the input guys it really helps. Link to comment Share on other sites More sharing options...
Omega5002 Posted August 31, 2013 Report Share Posted August 31, 2013 If I was gonna do only SQ, I would do infinite baffle with some Dayton's or run an isobaric setup like cablguy for a better linear response. 2003 Kia Sorento Team Subsonic LowsTeam Bassin' on a Budget2016 Rebuild Under Construction Best score: 150.2 at 40hz (3k, 2 Custom HDC3 15's) Usaci style(door open, in the kick) Link to comment Share on other sites More sharing options...
CleanSierra Posted August 31, 2013 Report Share Posted August 31, 2013 I think just as important as a good sub stage is having a strong mid stage as well. Like Sealed chambers in kicks or doors. Id want effective mids down to at least 80 Hz, maybe slightly lower. 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...
Omega5002 Posted August 31, 2013 Report Share Posted August 31, 2013 Of course, Cablguy is one of the best people to listen to when it comes to SQRandal: That's why Jacob is developing a line of SQ subs, SA's are awesome for daily but like you said, stiff suspension hurts responsiveness. 2003 Kia Sorento Team Subsonic LowsTeam Bassin' on a Budget2016 Rebuild Under Construction Best score: 150.2 at 40hz (3k, 2 Custom HDC3 15's) Usaci style(door open, in the kick) Link to comment Share on other sites More sharing options...
TaylorFade 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. Just to clarify... a ported box has a -24db rolloff (4th order). And a 4th order bandpass has a -12db rolloff (2nd order), but on both the low end AND upper end. Ported *can* sound just as good (or better) than sealed if done properly. It's just more difficult to get right. And not to get too deep, but transient response is a pretty big deal; and the more complex the design and the more energy devices, the worse it usually gets. Isobaric loading is lovely for SQ because of the natural cancelling of unwanted distortion. It will sound "funny" to a lot of people that are used to hearing that distortion though. And the boxes are tiny. But hardly noteworthy with today's small box drivers. IMO, nothing does SQ like infinite baffle. Link to comment Share on other sites More sharing options...
TeamHirshAudio Posted August 31, 2013 Author Report Share Posted August 31, 2013 So if anyone was to pick a SQ driver and box combo what would you do? Link to comment Share on other sites More sharing options...
TeamHirshAudio Posted August 31, 2013 Author Report Share Posted August 31, 2013 Would anything skar audio be good? like the MA8 or the VVX8? Link to comment Share on other sites More sharing options...
TylerParrish Posted August 31, 2013 Report Share Posted August 31, 2013 Would anything skar audio be good? like the MA8 or the VVX8? Depends, do you want a real SQ setup, or do you want something that sounds good?
