HSU STF-2 Settings

[audioblue]

Hello, I just setup the HSU-STF-2 and was wondering what settings I should adjust. Currently I have 5 Polk Audio RC60i's set at 100Hz and the sub set at 80hz on the receiver and the sub itself. I have an Onkyo TX-SR605 setup as 5.1. The Audessey program set the sub at -11DB. Does this seem correct? I only have the sub turned up at about 1/4 of the way. I just don't really feel any bass. What settings do you all recommend in this setup? Also, the audessey program adjusted all speakers except for the left surround rear to +3db. The left surrond was set at 0.

If the STF-2 has the crossover disable switch, you should turn the crossover on the sub off. If not, you should turn the crossover over on the sub to the highest setting possible, effectively taking it out of the equation. Let the crossover in the receiver perform the crossover function by itself, generally 80 Hz.

Set the speakers to the same crossover point you choose for your sub to start. From there, you can adjust the crossover to fine tune it to your speakers, room layout and personal taste.

You can also adjust the gain to suit your taste. If -11Db doesn't seem like enough for you, increase it until you are happy. Just don't push it past the limits of the sub itself, although I'm sure the STF-2 is a competent sub.

Thanks so much for your assistance. I'm actually starting the feel the sounds of the HSU. However, I have it turned up to +2 on the receiver. I had it at +5. At what point do you think it's too much bass? I don't want to blow the sub. I have it turned up on the sub at about 1/4. Also, when you mentioned turning the crossover all the way up on the sub, do you mean setting it at 90hz on the sub? I beleive that's the highest it will go. I then set it at 80hz on the receiver.

First off, what size room are we talking about?

No problem on blowing the sub (certainly not at 1/4 gain) as the amp for the sub, would cut-off before harming the driver.

The +2 on the receiver gives us NO indication at what level you are playing the sub.
Do you have a SPL meter?

Is this being used more for movies? or music? or 50/50?

The question (at what point is to much bass), is 100% a personal taste, so that is not an answer anyone can give.

And yes, that is what he means. If the sub does not have a bypass switch, set it to the maximum on the sub (crossover), and for ease of use, adjust it in the AVR.
(although, I am pretty sure that the sub does have a defeat switch)

No, I don't have an SPL meter. My room is about 19x14. I'm using strictly for movies. I appreciate all your advice.

I recently set up a new STF 2 and have a similar suggestion as DAVEMCC. Turn off the sub crossover and use your receiver's settings. Ideally you should try to have the sub kick in where your speakers start to get weak. If you have a test disk with a span of frequencies and a SP meter (Radio Shack makes a decent one for $50), you can do this "scientifically" but lacking that check the specs on your speakers, use your ears and try to find a level and crossover point that meshes so you don't have any big spikes or dips. I found that with my NHT speakers (which go into steep decline around 60hz) and the HSU sub if I set the receiver crossover at 60 and worked with the level control, I got the same results with the SP meter and my ears. BTW, I love the HSU sub.
