Um... I said that I'm using a 120Hz crossover, so there really shouldn't be much bass going to the surrounds. I'm using Neo6 or Logic7 most of the time.

120Hz isn't bass?
So where does 'bass' begin?

Logic7?
Ah Ken, i thought you were more refined than that.

Well, I don't know... what crossover should I be using? 120Hz is getting fairly directional.

Logic7 seemed to be better to my ears than Neo6 with my current setup. I don't like DPLII at all.

How about 80hz...

Through QS4s? I don't think so...

Well i again reiterate that the LFE material will be mixed for movies and high res discs to the subwoofer so a surround crossover should be set for 80Hz, given the Dolby specs for this purpose. I understand though that some surrounds are not rated for frequencies as low as 80 so you have to compromise. But really, do you think that 20-40 whopping missing Hertz will so greatly detract from one's experience of watching a movie explosion?
Bah.
Bloddy purists.

I am not sure i have Logic7 on my Onkyo. I don't recall ever seeing it, but i never use DPLII.
Not since i did that surround only listening test to see what comes out of them during the DPLII use. It was right weird.

Oh, there's the missing bit: I have an H/K, so I have independent crossovers. My M80s are crossed at 40 or 60 Hz, the VP100 at 100 Hz, and the QS4s at 120Hz.

That does help to solve the general dilemma.
I still run my surrounds on 'small' but have my sub crossover synced with the natural rolloff of the M60s around 50Hz.
Can't say i've missed any bass that i know of.

The difference is that big with QS8?

I don't know; I haven't listened to QS8s extensively. Dan? Over to you!
