Latest RL-p 12 experiment

[ClinesSelect 0]

I had only tried one RL-p 12 in my truck, due to enclosure size limitations, so the second one has been sitting on a shelf calling my name since the group buy last year. I finally decided to build a box for both of them which is 1.60 CF net with 1.5 pounds of polyfill and downfired. That is the largest enclosure that will fit.

While 0.80 net per sub is well under the optimum size, the subs still sound surprisingly good. To test the box I used my usual selection of the IASCA test disk, test tones off EMNB, some Dave Matthews Band and a little Van Morrison.

I am incredibly impressed with the RL-p and find it to be one of the best sounding subs before you even begin the tuning process. Even in, what is on paper, too small of a sealed enclosure, it is an absolute joy to listen to.

This is the 19th different set up for this truck and it will be staying in there for longer than the average.

man thats a lot of box building? i guess im lucky to not be as picky, or maybe i eliminated a lot of work by knowing what i wanted. good sound quality with plenty of volume, no ports for me, sealed or i.b only, yeilds great results with my rl-p. i like mdf and subs as much as the next bass head, but building several different boxes so close in specks would lose its appeal VERY quickly for me.

For me, experimenting with different subs in different enclosures is the most enjoyable aspect of this hobby.

you could try something diffrent, not just sealed or ported.

You mean like a Series-Tuned, 3-Chamber, Compound-Loaded, 6th Order Bandpass for a pair of TangBand 6.5" drivers?

Without going with a blow through or taking out the back seats, there is a very limited amount of space in a Dodge Ram QC. The box has to fit in an area where the OEM center console goes and still retain full use of the top section of the center console. That significantly reduces the available options.

wow nice to hear that, amazing that a sub that thrives in ported does so well in small sealed

[Adrian_D 520]

sorry, i missed the part where you said you ain't got too much room.

btw, nice TB box

but for real, how/what do i need to learn to design that enclosure?

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
