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.

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

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.

I am so jealous. Any more pics?

Now I feel special since I have two of them.

I ran one RL-p 12, both in sealed and vented boxes, on a PG Tantrum which showed ~1500 watts RMS on the birthsheet. With the gains set correctly and the right size box, it handled it with no problems.

Very well thought out and informative review.

The 2CF sealed is what I am looking for

I'm in Peoria

I'd love to hear it while it's here in AZ in December

When are you scheduled to receive the demo? I am curious about how it performs in small sealed boxes.

1.15CF net and 1,200 watts is a great combo.

This was a recommendation for the RL-p 12 on another site. I was just curious what everyone thought. For SQ purposes, try this: 1.2CF net (.6CF per driver), tuned at 24Hz, 22.5 ~ 25 square inches of port area. The problem is going to be vent length (causing the enclosure to be quite large), but it should sound extremely good if implemented properly. These drivers are best suited for low-tuned vented apps. They will work sealed, but if you can make this enclosure work, I think you will be pleased with the boost in overall output while maintaining excellent SQ and extension. The driver has an extremely strong motor. It doesn't need a very large enclosure at all, especially when taking into account the effects of in-car transfer function ("cabin gain"). That enclosure should yield a fairly flat FR and good extension which would be optimal for SQ. The problem with small low-tuned vented boxes is vent length. After you take into account how long the vent must be, the overall enclosure isn't so small anymore. But when implemented properly with a driver like this, they can yield some very nice SQ and extension and give you a nice SPL boost over a small sealed box.
