Well I am looking at RD audio Elite SPL and I can't decide if I want a single 15" or two 12"s. They both take 2.5krms and I will be using the 5750.1 to power either or so I will most likely see max excursion on the 15" and no so much on the 2x12" set up.....The 12's will have more surface area, but a 15" will be easier to install and the box wont have to be as huge....
I can use up to and around a 6-7cuc ft box tuned to around 47hz and am geared towards competing in db drag and iasca.
(I have an upgraded alt 250a and will be most likely tossing 2 batteries in the trunk)
i wouldnt run 5K + daily to the elite SPL. your much better running (2) elite spls because of cone area, less thermal abuse on each woofer, simply put its gonna be louder....
take into consideration these drivers are not flat down in the low 30's, there geared for high 30's low 40's and big burps. i would tune high like 38 and send each one 2500 and see what happens
I'm not 100% sure. But I will give my input. It seems that if you tune to your cars res peak, that your car would only be loud at that frequency. Which would be great for comps. There would be absolutely no flat response and every other note would be play rather quietly. Now if you tune lower say at your 38hz. it would have a flatter response up to your cars peak res. Just my thoughts. I would like to know the answer also.
Right. But here is a question. I have a pair of Q 15's which are supposed to play the lows really well. My box is tuned to 32Hz. I know that the higher the frequency the louder its supposed to play. In my ride it peaks around 42Hz and is way louder. Is that because of the res of my ride or just because higher frequency's play louder?
Just like Sean said,it's the car.Every vehicle has a different resonant frequency,well...some share the same res frequency but...it's based on the vehicle.
My current box is tuned to 47hz and I peak at 51hz according to the term lab; however, if I play test tones at 51hz and say 44-47hz I hit much louder on the 44-47 range.......
As I will need a new box for the new RD subs and I want SPL for comps but I dont want absolute garbage for music, no one hit wonder box.
(might be ordering the 5750.1 amp tonight or tomorrow...)
