Feel like I'm missing out on some low end *Solved with XXLS400*

The power output is it's peak power, so the BK will have 400w to drive to speaker when needed, not that it'll be using all 400w all of the time.

The higher power output will allow the subwoofer to play louder than the Z, but as has been mentioned the Z will have been tuned higher so will probably sound louder at certain frequencies.

I work in Salford if you ever get stuck and want someone else to cast an eye over the system. It will just take time to get it tuned to your tastes though.
 
Thankyou I may take you up on that offer at some point, I can't get the most optimal setup with my current flat due to the fact the most optimal setup would be more disturbing to the neighbor, where the sub is at the moment means if someone comes through door into main room, they get battered by bass.

Will the sub sound different as time goes by, as in, when it "breaks in"?

Bass travels, so wherever you place the sub will disrupt your neighbour to some extent. The woofer will loosen up the more you use it, you may find the sub will integrate better into your system the more you use it.

When I first set up my Monolith I was not impressed. It didn't really add much to the bass output already offered by my main speakers which are fairly low end (B&W 603 S3). A couple of days of trying the sub in different places... the thing weighs nearly 50KG!!! and tuning the gain and crossover... and it's a completely different beast. It's definitely worth experimenting with the sub in different positions in the room.
 
I moved the sub around and for where we sit to watch the TV, the best place is right of the TV, left facing. I would expect placing the sub in the corner nearest to the neighbor would be much worse for next door than at the opposite side of the room? I feel it already integrates in, not overpowering at all and I can't pinpoint the sub really

the frequencies subwoofers use it's meant to be practically impossible to pinpoint them if set up correctly.

also the best way to position a sub is to place it where you normally sit. then move around the room until you can find somewhere it sounds best. then swap the positions. as in put the sub there and then you place yourself where you normally sit.

i didn't do this. i only have 1 position where it works in the room. so it's there. doesn't make any difference as i then used the AVR mic to calibrate the sub to the system.
 
I've got the XXLS400 and it's awesome, though I probably need to get it set up correctly. I don't think I changed many of knob positions on the back but ran the Onkyo room calibration thing. I'm by no means an audiophile but it sounds good so I think the settings are somewhat correct. I will have to dig out how it is currently set up but there is some decent bass if needed. I was watching Saving Private Ryan a while back, the scene at the end where they are hiding in the shell craters and the Tiger tanks are approaching, DAMN that was generating some LFE! I will grab a picture of the pack of the sub and see if people think it's way out.

If you've used the auto set-up wizard on the Onkyo then it will have taken care of most of the setup for you. Your sub controls should be set as follows:

Volume - about 50%
Phase - 0 degrees
Crossover - Highest number / fully clockwise / LFE position (whichever is applicable)

Thanks, this is how it currently is:

Set up is as follows:
Onkyo TXNR676E
B&W 685 S2
B&W HTM61 S2
B&W M1 mk2

There are five dials, I wonder which one is massively out!!??

when i did my calibration i put the volume on the sub to around 35% then after calibration whacked it up to 50%. i like my bass. i know i will have messed up the calibration slightly but i wanted more bass.
 
I've got the gain set to about 20%, with the Neutrik connector the gain is much lower, when I have it on the RCA, gain is about 70%.

I didn't realise BK are quite flexibile, I could have ring them up and asked for a BK XXLS400-PR, that would have been so good with a passive radiator in that thing too.

TBH i'd set frequency to max and use your amp to set a crossover (unless it cant and i missed it). Also, are you sure you need to change the phase?

Also, does 'out' on the filter mean not in use?

Out means control it on the sub. In and it's for the amp's bass managements, I have mine to out because my amp has no bass management.
 
Out/LFE means the sub's crossover gets switched off. Use this if you hook the sub up to an av amp with a filtered LFE output. Use in if your amp has no bass managent. This allows you to use the crossover on the sub.
