Posted January 26, 200520 yr i want to get 2 RL-p 12" subs. I want to run 750 watts rms to each sub. does any one have any ported box desings that would fit this sub that i could have? or the size of the box and port, and tuning frequence? thanx in advance
January 26, 200520 yr i want to get 2 RL-p 12" subs. I want to run 750 watts rms to each sub. does any one have any ported box desings that would fit this sub that i could have? or the size of the box and port, and tuning frequence? thanx in advancewell, mike suggests between 1.5-2ft^3 per sub with a minimum of 20in^2 of port per sub and a vent fb of 34hz.with 750wrms, i'd suggest somewhere in the neighborhood of 3ft^3, 36-40in^2 of port tuned to 32-34hz.if mike doesn't get here quick enough u can...email [email protected] with what ur are trying to get, he'll have a lil more insight as to what size enclosure will work best...if u have any more questions, hollar...wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
January 26, 200520 yr Author so about 3ft^3, 36-40in^2 of port tuned to 32-34hz, for both subs or just one?
January 26, 200520 yr Admin I think kent means for two subs, that is my guessif you need help with a box we can build it, if not we could do a design if you want
January 26, 200520 yr I think kent means for two subs, that is my guessif you need help with a box we can build it, if not we could do a design if you want<{POST_SNAPBACK}>r u looking for sq or splwhat car is this going into?80can whip something up
January 26, 200520 yr Author i am looking for more spl than sq, but still want to maintain some sq. probably like 70% spl and 30% sq. the subs would be going in a 2000 nissan maxima.
January 26, 200520 yr Kent's rec is solid. If you're lookin' for a touch more output, consider bumping up the combined net volume of the enclosure to 3.3-3.6 cu ft.
January 26, 200520 yr Author so if i make the box like 3.5^3 feet, how many square inches should the port be, and what frequence wounld it be at?
January 26, 200520 yr so if i make the box like 3.5^3 feet, how many square inches should the port be, and what frequence wounld it be at?<{POST_SNAPBACK}>MAKE THE PORT 56SQ AND TUNED 2 45HZ80
January 26, 200520 yr so if i make the box like 3.5^3 feet, how many square inches should the port be, and what frequence wounld it be at?Link to Port Calculation Equation45 Hz is a bit high, I would recommend stayin' around 34 Hz.
January 27, 200520 yr so about 3ft^3, 36-40in^2 of port tuned to 32-34hz, for both subs or just one?i see where my recommendation was confusing, i was quoting half the power but recommending the full enclosure..oops!my suggestion, since ur after a 70/30 split or so, with 1500wrms for the pair, is 3.3-3.5ft^3, 40-42in^2 of port tuned to 34hz. that will give u solid output while maintaining excellent sq. at the most, i'd recommend a tuning of 38hz..lil more output up top with out sacrificing all ur sq.oh yeah, that's a combined net volume..lol...and also what denim said..wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

January 27, 200520 yr Author last night i tried to design a box. the port was on the side, and it was a slot port 2" wide, 14" tall, and 11"deep. the box it self was 28"wide, 14"tall, and 16" deep. these are all internal demensions. the box volume came out to be like 3.6^3 before displacemant and bracing. i believe the box would be tuned to 34hz. i was wondering i you guy could just check these demension to see if they would work.
January 27, 200520 yr last night i tried to design a box. the port was on the bottom, and it was 26" wide, 3" tall, and 11"deep. the box it self was 26"wide, 18"tall, and 16" deep. these are all internal demensions. the box volume came out to be like 3.8^3 before displacemant and bracing. i believe the box would be tuned to 34hz. i was wondering i you guy could just check these demension to see if they would work.<{POST_SNAPBACK}>i'll look into that right now

January 28, 200520 yr 00maxima....can u go bigger with the box?i have one done, but it's larger then the one u have posted...wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
January 28, 200520 yr ya i can go bigger.ok..here's what i figured out..these are external dimensions..15.5" tall x 34" wide x 18.5" deepport will be 14" tall x 3" wide x 25.1" long this will roughly give u a net of 3.5ft^3 tuned to 34hz. using 3/4" mdfmike, whatcha think? 00maxima, if that won't fit, lemme know...and let me know where it won't fit..wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

January 28, 200520 yr > mike, whatcha think?I think you guys are awesome for watching my back! Good rec's.

January 29, 200520 yr dont mean to whore but does anyone know offhand if the trunk size of the maximas changed from 99 to 2000I know the body style did, and the reason I ask is because Ill be getting that 99 maxima (you might have seen my thread abt it) and wanted to know if this box owuld work for mesry again abt the whoringThaksTom
