I can’t speak to the L12, which looks like an entry level sub, but I’ve had experience with the F series. I’m currently using an F 12 SE with a paper cone for my small HT, but originally ordered it to play with my two channel hi-fi. Well made, easy to set up and a lot of product for the money (even though you can buy cheaper subs). I recently bought a pair of the high powered F15 with the piano finish-- these do not give you the option of a paper cone driver, only aluminum. But, I’ve managed to get them to blend pretty well with my two channel audio system through placement, room treatment and settings. I’m crossing over pretty low- at 50 hz, because I’m trying to reinforce a full range speaker system that already has "woofers"- so these add a foundation. You can also add an inexpensive DSP unit, and still keep it at a reasonable budget. Talk to Brian Deng, the owner. He’s very helpful, not a "salesman" type. Good guy, good company, good product.
