logspace Posted August 10, 2012 Report Share Posted August 10, 2012 I've got 2 12" Alpine R's. I prefer SQ, but these aren't really SQ subs, and everyone has recommended porting them. I would like to put them in a ported box, or two separate boxes if this is better. I listen to lots of metal, house, and dubstep, so lots of fast beats and some rapidly oscillating bass lines. I want to hear each note and want it to be clean, rather than pure SPL. I'm thinking of using a small volume and low tuning (in the high 20's). This will be in the trunk of an 05 altima. This link is to box plans for this sub. Can anyone verify if these plans are for 1242D type R's? Are the plans any good? any suggestions or plans are appreciated. here is the link: www.caraudio.com/forums/enclosure-design-construction-help/137804-free-box-plans.html Link to comment Share on other sites More sharing options...

01 S-10 Posted August 10, 2012 Report Share Posted August 10, 2012 I would not tune in the 20s, too low IMO. 34-35 hz would be a better option. Do one box with a common chamber for both subs TDH FTW !!! Link to comment Share on other sites More sharing options...

logspace Posted August 10, 2012 Author Report Share Posted August 10, 2012 why would the 20's be too low? not being a smart-ass, just curious. does much music have notes that low? Link to comment Share on other sites More sharing options...

412 CVX Posted August 10, 2012 Report Share Posted August 10, 2012 why would the 20's be too low? not being a smart-ass, just curious. does much music have notes that low? Home theater boxes are usually tuned that low because action movies often produce really deep rumbles that drop down into the 20's, sometimes even inaudibly low. Music, however, doesn't drop below 30 very often. Unless you're listening to Chopped and Screwed/Slowed music a lot, tuning that low will hurt a lot of your upper end output. Regular music won't be as loud as it could be, and potentially could sound weird. You can play frequencies below tuning Just say no to Ground Pounder Customs. My temp system build log More box buildssome cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches! I'm with captain stupid.

logspace Posted August 10, 2012 Author Report Share Posted August 10, 2012 Ah I see. That makes sense. I will probably tune it around 32 then, unless this is still low. Link to comment Share on other sites More sharing options...
412 CVX Posted August 10, 2012 Report Share Posted August 10, 2012 33-35 is my preferred range. I'm kind of ocd about it and i have no idea why. 32 should be fine though.
