802 Diamonds / HTM2D / Onkyo 5509 Processor and DB1 Sub

[Edgeyboy]

Just starting installation of my DB1 into a system comprising of:

802 Diamonds FL and FR
HTM2 Diamond Centre
CCM818 Rears and Surround Backs

Onkyo 5509 Processor

Fed into CP800/CA3200 to power fronts, CAP2100 to power centre. Both on HT BYPASS and a Rotel 1565 to power rears.

Up until now, I had 802s and HTM2D set to large with the CCM818s set with a 60Hz Crossover.

Now need to install my DB1.

Shall I leave speakers size settings as they are or change all to small and route all bass through the DB1 ?

This only affects 7.1 surround sound use. For stereo, I use the CP800 and CA3200's on their own.

Yes, you should set all the speakers to small and, if you are committed to 60Hz for the CCM818s, set them all to that frequency.

Thanks Kal. I can set a different crossover for each speaker - is there an advantage to having them all set to 60Hz if, say, the 802's can go lower ? Thanks Tom

I would start with 60Hz and then experiment. Without a lot of data, no one can predict what would be optimum.

Many thanks Kal. I'll use that as a starting point. Tom

I know the most common recommendation is to set all speakers to small and let the sub do the job, but in my setup I actually think that takes away something.
My bass response is much better measured with the front speakers set to large. Now that may be due to acoustics but just want to say that sometimes the general rule is not the way to go.
For ref my system is 802Ds, 855 sub and HTM4S. Rear are SCMS.
Classe SSP-800, Classe amps... Etc.

Of course. Audyssey is a great application and it assures most of a good outcome. OTOH, it is not a replacement for a good measurement setup and individual tweaking.
