Outlaw LFM-1 EX on the way. First major sub for me -- will post impressions in about a week!

Please do. I am seriously thinking about one also but I would like to hear what others have to say first. I would really like to know what difference the plug makes in the overall performance.

Looks like a pretty substantial "first major sub" - look forward to hearing your impressions.

From a purely "numbers" standpoint, the plug and associated switch should decrease output volume by a few dB (roughly 3dB, just enough of a change to be detectable by the human ear) while allowing the sub to go about 6Hz deeper (16Hz instead of 22Hz) - sort of a case of "do you want louder or lower?" Although in the case of the EX, the "lower" mode should still give you rather a lot of volume...

Arriving in a few hours! Will post impressions tonight!

- Looking forward to it.

Well, LFM-1 EX is up and running and sounds great. As I was hoping the aesthetics go wonderfully with my ebony Polk LSi speakers (with the glossy black top).

The Oliphant Charge in Return of The King and the final scene of The Host at 1:43:10 had some sub 20hz bass and it was certainly very loud and very impressive.

I played around a little bit between max extension and max output, but not enough to tell a strong difference, in part because in max extension it gets louder than I would ever want it in my rather small room (13x10x8).

I don't have much to compare it to as my last sub was a cheap end 8" Velodyne that got down to 37hz (though I do use a Buttkicker LFE that goes down to 5hz... but that is very different). The differences have been pretty astounding, for example the fight scenes in 300 with the giant you can really feel the punches and blows. Great stuff.

The ButtKicker has gotten me used to really feeling deep bass (at least on my... butt), but this is still a huuuge improvement as now I can feel it everywhere and experience heavy room compression and that punch-in-the-chest feeling. I have yet to do any proper setup with SPL meter and calibration disc, so it may improve a bit later down the road.

Sounds like the EX is working out nicely for you!
- Yeah, in a room that size, I guess an EX could give you all the SPL you'd want even in max extension mode.

Well, I picked up an SMS-1. I have only spent about 10 minutes with it, but it is very easy to use.

Anyway, the LFM-1 EX in maximum extension is pretty much flat to 15hz in my room, so it certainly goes deep!

Flat to 15Hz in-room in maximum extension mode... Yeah, that's getting pretty darn deep.
