Sub X-overs/internal,external

Hi KAl,I do use the bass management in the AV-8.
I don't use the subs crossover at all.
My 50as go down to 32-34 hz,so I am using the AV-8 crossed over at 60hz.I mainly run stereo direct as it bypasses all the digital.I use the dacs in the Bryston BCD-1(analog outs.Don't get me wrong I really do like what I have.
I just thought maybe a Bryston 10B sub X-over(cost as much as my Velodyne)I might get more excellent bottom end.I know the
Arcam's X-over is fine and so is the velodyne,if i had a Highend X-over,you would think I'd have a major improvement
on the bottom end,and then maybe not.

Did not see how old this was but am setting up my Audio
with a AV-8 in my system.

I want to use all 3 of the sub outputs for my particular configuration.

I went this route,as i have one DD-15,i had some Cardas grc
Y cables(this is for the music side)set my 50as to large,I ran two Ycables from my
AV-8 R+L main preouts,from the right Y,I ran two cables,one went to the sub input and one went to my 7B-sst and the left Y,I did the same,SOLIDand it is in preset 1(in the AV-8 LFE input)and I use the AV-8
X-over at 60hz for movies,perfect,except I would like another for R+L stereo,Spring time perhaps.
