My 1500 sq. foot room

I bought a STF-2 for my 2 channel small (1500 sq. feet) room and mated it with my polk audio lsi9's. It just seemed a little big for the room so I moved it to my living room and tested it in a home theater application --OMG. I loved it so much, turned up almost 1/2 way, for movies that I ordered a STF-1 for my 2 channel room.

The problems I was having with the STF-2 was that not alot of music even goes down below 50 hz. So if I had the STF-2 on it seemed too loud when I got signals below 50 hz or crossed over at 60 hz. My thinking is that I can cross over the STF-1 a little higher and not get so much spl. Plus it is a smaller driver and might be more musical in my small room. What do you all think?

P.S. The HSU STF-2 is awesome in my living room for movies (just watched Master and Commander-OMFG). HSU quality imo is awesome thats why I ordered the other one.

Especially if your receiver did not include an equalization system for the sub range, your perception that the STF-2 was too loud in your small room might easily be an issue with your room and the position of the sub and your chair.

If you set the levels on the sub using signals from an audio test disk, your choice of crossover might explain its being loud. For example, if you use band limited pink noise 30Hz-80Hz to set the sub level, but the crossover is set low, you will end up setting the sub too hot so that the average level is still 75dB. I noticed my Denon receiver avoids this by disabling Audyssey equalization and the crossover when it plays its test tones.

Hi,

The fact that the STF-1 uses a smaller driver has nothing to do with its musicality.
What will happen is that the stf-2 can play louder with less distortion than the STF-1.

Your right about the musicality comment, I take that back. The fact of the matter basically boils down to; after seeing what that stf-2 can do in my home theater set up (and small room 2 channel) no way in hell is it leaving the theater room lol. Room filling bass that makes me feel as if I am in a state of the art cinema theater.

I think the stf-1 will be perfect for my 2 channel listening room (if it takes after the 2 in any shape or form). When I was setting up the stf-2 I realized how incredibly powerful and high quality the sub was(too much for my 2 channel needs imo). This was what lead me to test it out in the home theater room.

I am thinking the stf-1 will be great for my musical tastes (no pipe organ music love here). My lsi-9's go pretty low for bookshelves. My amplification only gives full range signal to both the speakers and the sub hence the 50-60 hz cross over points I mentioned. Low volume levels is what I am listening to mostly so I think the stf-2 was over kill for my 2 channel. So basically I hope the stf-1 is a chip off the ole block of the stf-2 (I think it is from internet research). Wish fed-ex would drive faster lol, cause my sub is on the way- yay!

Yep. In that case, I think it will please you just fine.

Take care man,

Well it came in today. Yes the problem was my room was just too small for the stf-2. The stf-1 is perfect, I love it.
