1. The review lists the freq resp as 25-180 +/- 2 db. The manual (combined LFM1 and LFM2) lists it the same. However, the Outlaw product desc page:
http://www.outlawaudio.com/products/lfm2.html
lists it as 28-180 +/- 2db

So, which one is the correct one ? (I think the product page is correct...)

2. In the review - http://www.hometheaterhifi.com/volume_13_2/outlaw-lfm2-subwoofer-5-2006-part-2.html
- Pg 2 - look at the graph. The in-room SPL is > 100 at 20Hz, but it falls between 38Hz and 48Hz and then picks up again. Little strange, isn't it?

For a sub with a +/- 2db freq resp of 28-180, that is a very impressive SPL of 100 at 20 Hz...

I guess Dr. Hsu and the Outlaws really worked hard at this...
