Posted March 18, 200520 yr Hi everyonefinally ordered my sub... see this thread http://www.soundsolutionsaudio.com/forum/i...?showtopic=2502my amp is a 350Watt Rythmik audio plate ampthe sub will be used for both HT and music 50/50. I wld like a ported box tuned low.BTW, 4" ports are quite hard to come by in my country....is there likely to be chuffing if i use an ordinary piece of PVC pipingregards
March 18, 200520 yr man, i know nothing h/t to help with ur box. i would wager something in the 2-2.5ft^3 range would work, tuned to 28hz or so..also, if using regular pvc for ur port, for the part inside the box, round over the end completely...on the part facing the outside of the box, round over the inside edge...that will help eliminate noise...wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee :Slaeyr:
March 18, 200520 yr I'd probably tune lower for HT, maybe around 20-25 hz. 28 works well for the car, but you want to be able to hit the really low notes in a lot of movie scenes. But i don't know what's best for the woofer so it'd be best to let mike chime in on this one.
March 18, 200520 yr yeah, i understand...fs is 24hz for the dual2..so tune there...that sound about right?wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
March 18, 200520 yr Indeed, a 2 - 2.5 cu ft net enclosure tuned to 22-24 Hz, with 35 sq in of port area would work well for the RL-p12 on home theater duty.

March 19, 200520 yr > how would a rl-p tuned that low in a car sound?Unecessary With the effects of cabin gain, you really don't need to tune that low to get great low frequency extension in the car. For that matter, I've always been quite happy with sealed enclosures for my car woofer experiences.. but hey some people just like more output
March 22, 200520 yr Besides, most music doesn't have material that low anyway 25Hz maybe, but probably not much below 20...movie soundtracks, recorded with seperate LFE reels, do.
