I was looking at the DD 6.5 subs first, but saw these and think they might work as well but are cheaper. Pulled the specs from their site and will power them with an old Rockford 800a2, so a clean 800 rms 4ohm. Each sub will see 200 watts at 4 ohms which also works better for my amp.

impedence (ohm) 4
power (rms) 150
power (peak) 300
vc (inch) 1.5A/4

qms 4.334
qes 0.438
qts 0.397
n (%) 0.113
SPLo (dB) 82.6
vas (L) 4.423
Cms (mmm/N) 206.84
Mms (G) 51.5

OD (mm) 166.5
OH (mm) 122

I was orginally thinking a 4th order at 1 cube common sealed and 1.5 ported at 50hz. I hadnt figured out port area, but want it to more musical so would be smaller. I also kicked around the idea of a T line. I dont car about metering or SPL. Looking for decent thump from 70 down in a Pathfinder Hatch. I also want to get as much low end out of the set up as possible thats why the thought of a T line.

What do you guys think?

Guessing at bp and TL type designs is not the best way to get a good enclosure. Any reason you want to use tiny subs in a big box?

To be honest, just because. I have a bandpass T line for a 1508 and it sounds incredible. Im really trying to figure out how the guy did the design so I can do on 4 small subs. I have seen several guys using 4 8's and multiple 6's and they love them so I figured why not try.

ur gonna run that amp in a 2ohm load to get the 200 per sub.

I have to play with the series/parrallel wiring, but if I end up at 2 ohms Im ok. Ive run the amp there before, but cant go lower than that. I thought with series/parrallel wiring, you could get 4 4ohms driver to a 4 ohm mono load?
