Thus, the 360's can play a bit lower than 80 Hz but I have found they sound better when left at 80 Hz. I have tried them set to "large" but notice no real advantage. In fact, it kinda muddies things up a bit due to some over lapping between the natural roll-off of the 360's and the 3.3 X-overed set at 80 Hz. I suppose this may be due to some cancellation/phasing issue(s). The best thing to do is to experiement around with the "small" and "large" settings as well as different X-over points. Only you can really decide what sounds right to you. My receiver allows for X-over settings of 100 Hz, 80 Hz, or 50 hz. Of these, imho the 80 Hz X-over point sounds the best in MY room. Once again it may be a good idea to consult w/Dr. Hsu or Peter Marcks as they both are more knowledgeable than I. Hope this helps bori. Craigsub may can offer some sound advice as well.

It is good to have different tastes because if we didn't then we would own the same things. Oh brother, just think how boring that would actually be. So, bori I did not get fired-up but Rather more inquisitve as to how such and such arrived at his conclusions.

I thought I might be in trouble when she called and said the delivery had been made and then complained that she thought it would be WAAAAAY too big. Once I got home and got it connected and demonstrated how good it sounded she was all smiles. :wipes sweat from forehead: We got out some CDs and her and the kids danced around. Good times...

So less than 24 hours into ownership I am thrilled. I was so impressed how good it sounded right out of the box. My new Aperion speakers show up next Tuesday and then I'm off the week between Christmas and New Years so I'll have plenty of time to mess around. Can't wait!!!

If the sub is half as good as the service has been, I will be one happy camper!!!

I've had it setup for a couple days now. Had to tweak things down on the Onkyo 805 as I was replacing a rather small Mirage Omni S8. The test tones nearly blew the windows out in my living room. From there I played U571, Apollo 13, and Transformers on HD DVD. The sub performed beautifully!
For music I did Guns N Roses, Beatles, some house and hip hop all on vinyl..again was very pleased. Currently running it with 1 port open.
I thought I'd be second guessing the 2.3 purchase vs the 3.3 but I havent thought about it once as this sub delivers everything I need!

I have it truned up 30% and the most important part is that the gf was very impressed at how it shakes the sofa.

Bori, turn off the eq on your receiver and calibrate each sub by themselves to 75db. Once you have done this, turn on both subs and adjust the gain knob until you get 75db with both subs running (you will more than likely have to turn both gain knobs down).

Once you have the gain knob on both set so you get 75db with both subs running, take note of thier position and run audyssey on your receiver. After it is done, play either a bass heavy movie track or music and see if one sub stands out more than the other. If so, adjust the knobs on each equally (one up some one down the same amount). Play the same movie or music track again, continue to adjust the gain knobs on both subs until neither stands out more than the other.

Using your spl meter, make sure that you are still at 75db with both subs running. If you want you can re-run audyssey to make sure evertyhing is still level.

Sit back and enjoy your new toys.

I'm surprised at what a beast this thing is. I turned the gain up to 50% this evening while listening to some Oakenfold, as a result the dog ran away and the vibrations started skipping the Tosh A35 which I was using as a cd player. This is with the sub set to -3 on the 805. Oh and the A35 is at the direct opposite point of the room, about 14' away. So back down it goes to 30%. Simply awesome.

Bori, you have to decide how hot you want to run your subs. Keep in mind that a 75db reading on the spl is already 3db hot (explained earlier in this thread). Now, if you run the subs with a reading of 81db then you are 9db hot. If you tend to listen to your movies/music at a high volume you may end up pushing the subs to its limit to the point of having distortion and or compression. You will also be overpowering the rest of your speakers theeby drowning them out, again, that is for you to decide. the point of getting a 6db boost while running dual subs is that you can now turn the gain knobs down on both subs so they aren't working as hard and you have more headroom.

As for the eq, you can calibrate it with the eq on if you like. When I initially calibrated my subs, to find where I was setting the gain knobs on both I chose to have the eq off, get the gain knobs set, then apply eq. If you run the eq first, then adjust the gain knobs, the settings that the eq was adjusting to have now changed so in effect you the eq may cut a frequency that it may no longer need to (I could be wrong on this so don't quote me).

Good luck
