heres an extremely well put together test that was done in the last couple of months by some db drag competitors. the tests were as equal as can be, all tests done in the same car with very similar boxes, based on manufacturer recommendations. probably the most comprehensive subwoofer comparison yet.

Realm of Excursion

wont let me directly link for some reason, but its under subwoofer and great 12 challege test results.

 

Although it was just posted on that forum yesterday, the results were posted on other forums a week or two ago. After I read about the disappointing results of the Dayton Reference sub, it was brought to people's attention that they had a defective one.

 

i like how the fi q 12 owned the jl w7 and si mag at almost every frequency at half the price. im afraid of what will happen when i get my system finished tomorrow or next week.
