4 American Bass xd 6.5 subs 4th order or T Line

Recommended Posts

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.

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

Xmax (mm) 8

MD (mm) 105

OD (mm) 166.5

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?


HU - Pioneer

Front Stage - Old school MB Quartz run off a JL e2150

Rear Stage - Stock - well one works, LOL

Sub - Tang Band 740C in between the front seats

Sub Amp - A tiny Kenwood. - because it fits under the seat.

Total Spent on everything $50.

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.

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?
