I have read that this sub has some rave reviews. After a heads up, I went to compusa and picked one up. I installed it in my current setup(HK AVR325,M22ti,vp100,HK HKSUB 12. I am thinking the HK sub does better than this hsu. The hsu does go a tad lower but it seems to "bottom out" way faster than the HK. Is the HK 12 a decent sub? Does anyone have any experience with the two or can offer some insight? Both x-over @ 80hz. Thanks,Blake

Do you actually hear it bottoming out? Like metal hitting metal?

Have you calibrated?

Dont know if its metal on metal. I think the amp is overdriving the xsus of the driver. Not totally sure what you mean about calibating. I am a newbie of sorts.

More than likely you are over driving the sub......ie the volume on the sub is set to high.By calibrating Curtis means have you matched the volume of all of you speakers including the sub.Do a search on calibrating you should find plenty of info on it here in the forum.Its impossable to set up a sub correctly without doing so.

Kraz,

A Quick Overview of Home Theater Calibration

CALIBRATION TECHNIQUES

Calibration is an absolute necessity. It's generally accepted that if one tries to balance speaker volumes by ear, the sub is usually set way too hot. This could be the reason for the STF-2 "bottoming." I have the STF-2 in an 11.5x18x8 room, and have never had any problem with it bottoming.

At what setting is your subwoofer volume right now? After I was done calibrating, the volume control was only one hash mark above minimum, due west on your compass, 9:00, 270 degrees. Start with lower volume and get accustomed to what strong, clean bass sounds like. THEN you can start turning it up.

wid, Ajax, Twirly,

Thanks for covering me.

Curtis, next GTG (or the next one I'm able to attend), you can buy me a beer.

Kraz, Do NOT be concerned about being a "newbie of sorts." All of us were one of those at some time. That's what forums, like this one, are all about..........helping others figure out this subjective, complicated, but rewarding, hobby. You got questions? Ask away. And, if someone attempts to make you feel stupid, simply ignore them.

Jack....I could get my Cleveland girl to bring you a six-pack when she is visiting.

Get her to bring me your 340s and it's a DEAL!

No deal! All you get is beer.

Curses! Foiled again. DRAT!

Another thought/possibility to consider:

Some of the early production of this product had manufacturing issues. From what I've read over in another forum, serial numbers <1800 have the potential of being from the affected lots.

So what is your serial number? And have you done the "Darla" test? That's where lots of folks seemed to have noticed the issue.

Gotta love the "DARLA TEST"
I tried it last night for the 1st time with my STF-3.
I must of played it 10 times it sounded so great.

It's one of my favorites. What's really cool is that it makes my entire fireplace resonate, and adds this really creepy creaking sound. It's somewhere around 25Hz. Drives everyone crazy.

Try Black Hawk Down, lots of rapid gun shots and explosion that will thump your chest continuously, this is by far one of the best war movie I've ever seen. The Star War EP1 pod race is just as amazing!!

OK - I gotta ask (and I do so with some trepidation) .

Just what is the "Darla Test'?

A scene from Finding Nemo at around 1:18.00, Darla was tapping on the fish tank and made some brain numbing and earth moving bass, I haven't measure how low it hit in my room but it's in the low 20s to high teens range. It sound sorta like THOOONG THOOONG THOOONG THOOONG with my SVS PB1. :-)

Warning: weak ass woofer such as Bose's Acoustimass bass module need not apply.
