Subwoofer setup question

YUP!!! You've got it!

Ok after much fiddling I have set my sub up as described above.

I have the sub connected with BOTH connections and the volume for both inputs set to 75db.

I also set the front speakers to large as I assume the whole thing would be pointless without doing so.

Now im still confused about the roll-off. The test tells me that I need to get an even sound with no gaps, but no matter if I have the roll off at min or max there is always a continues sound. At min there does not seem to be that much action from the sub, with only a tiny bit of rumble, but with the roll off set to max there seems to be lots more rumble but the bass does not seem overblown.

Is there any chance that there is anybody else with a pair of 603s and a REL Q100 ? If so how do you have your roll off set ?

Also just from the tiny demo I had with this new set up I have found it to sound better this way

I'm curious as to why you think your sub could/should be performing so much better.
What are you unhappy about?

SPL?? Extension?? ??????

Can you feel an upgrade coming on??

Cheers

The main thing is that I have heard q100s sound much better than this.

Im very happy with those low rumbles that are produced but am still trying to obtain those hard slams and crunches ( skull crush on T2 ) that I had in the demos before purchasing

Duncan,

I know this sounds obvious, but you have got the cinema EQ set to OFF, the LFE at ZERO and Tone controls FLAT have you not?

Duncan,
The X-Men Movie DVD has an Audio and Video set-up in its Special features. Good for setting-up Home Cinema Equipment. Just follow the on-screen instructions!
It helps if you have an SPL Meter, but not absolutely necessary.

The THX opti-mode settings are only on the r1 version

So Duncan, you're happy with the low rumbles but not getting the midbass punch.

Could be a room null.
I was in one with the first position of my sub. It was difficult to tell by ear. I still had plenty of bass impact but I knew something was not perfect.
So I plotted the subs response at the listening position, 16-80Hz in 2Hz increments. Low and behold there was a 20dB null at 42-48Hz. Sounds a bit like your scenario.
I moved my sub to the other side of the room and now it plots pretty flat. The difference in sound was amazing.
Something for you to do this weekend.

If you go here- http://members.tripod.com/~terrycthe...um/page12.html
At the bottom of the page you'll find some files containing various test tones you can download and use. There's a MP3 file for specifcally manually charting and plotting (15-80Hz Sweep, 1Hz increments 5 seconds each).

These are the correction values for the inaccuracies of the Tandy (RadioShack) analogue SPL meter.-
10Hz add 20
12.5Hz add 16.5
16Hz add 11.5
20Hz add 7.5
25Hz add 5
31.5Hz add 3
40Hz add 2.5
50Hz add 1.5
63Hz add 1.5
80Hz add 1.5
100Hz add 2

Doing all this will be very helpful even if it's not a room mode problem.

Cheers
