highest db with the lowest amp draw

[crunch1 0]

just a thought what would you think would be the highest db set up with the lowest amperage draw.

Basically the most efficient system with the highest db's

I was wondering what was on the other side of the spectrum.

Nowhere near the best, but I did a 141 on music legal on TL in my expedition with about 400rms of Boss power on 2 Xplod 12s. Was a bo I designed for my friends civic and let him build it (he did a horrible job) then when I took my 6 15s out it was sitting in my garage so I hooked it up using wire I found in my closet. Total cost $0.00. Now thats some budget bass.

~~~sweet~~~ 141 on a TL at 400rms

Going to take some very large enclosures...

Really efficient horn-loaded subbass enclosures aren't going to fit in cars or smaller SUV's, even space-saving designs like the Decware Wicked One get big in a hurry if you scale up.

I would go with a dual acoustic suspension bandpass...

Seriously, though... try some PA speakers that still have healthy x-max figures like the B&C 18TBX100. Has a very flat response ported... it's over 2% efficient (many car subs are 0.2% efficient) and has a 4" VC and extensive motor venting so it'll keep being efficient under high power. If space was no consideration, as Jim said, you could build a horn setup with such a driver and achieve ridiculous SPL with a few hundred watts.

I would think a Transmission Line tuned to the car's resonant freq and boosted around there also would be sweet. Get a driver with high sensitivity, the T-Line will lower the power handling anyways, and you'd be extremely loud. The TLine would be huge though.

I met a guy who goes by SlickRick on some forums. He had a single 12" Avalanche powered by a Directed 600D. He hit a 142 legal on the TL.

Box was ported insanely high from what I recall though.

Well this is got me thinking a bit. I was thinking of competing in the street A class where your restricted to one battery and a 1f cap (if you choose to use one) and one sub amp (not counting another amp to run fronts rears) one 12" sub or two 10" subs or three 8" subs.

So I was tossing around ideas for the best setup possible and then a vehicle to house it all in. heh
