Bass settings on Onkyo 805

[griffinconst]

I just got a pair of Jamo 450 speakers. This changes things from bookshelf's to towers for fronts. Should I still have the " double bass" setting on and let the audessy set the crossover or should I set it 20 above the low end of the speakers frequency response or what? Should the setting be full range? Please help if you can. I have 3 hours to crank it up starting now, 4:45 pacific daylight time.

Sorry
I forgot to say I have a sub.
Thanks

First I would never use the double bass setting unless you were listening at low volumes and need a little extra boost but never use it for higher SPL's unless you don't like your speakers.

You should rerun Audessy but still run those speakers as small and you still want at least a 60hz crossover. Even though they are towers they are not going to go down to 30hz that the specs may state.

If you want to see what they can do as full range stereo just use the direct mode which will not use the sub.

Are you familiar with the 805? It doesn't actually have a "small" setting. Unless I just can't find it. I think the Double bass seting is the "small" setting on this model. I may be wrong but there is nothing about setting speakers to small in the manual. Many have told me this but I just can't find any reference to small setting.
Should I just set the crossover to 80 like the THX setting or maybe 60? My speakers specs are 38hz-46khz.

If I reset the audessy will it take care of everything?
Thanks again

The 805 allows independent xover settings for each channel so it uses 'Full Band' to signify 'Large' and the actual xover you want if the speaker is to be set to 'Small.' Older models that used a single global xover used the Small terminology because any speaker set to Small would use that single xover; now you can set each channel to a different xover frequency.

Double Bass requires the front speakers to be Large so you'd have to set them to Full Band to be able to use Double Bass. Double Bass sends the bass from the front channels to both the front speakers and the subwoofer whereas if the fronts were set to Small (specify a xover frequency), only the sub would get the bass below the xover and not the front speakers.

I agree with the previous posts - no double bass, but wanted to add a caution. For some reason my 805 turned double bass back "on" after redoing the auto-setup process. Therefore, I recommend that you recheck to make sure double bass is off after rerunning auto-setup.

I have DefTech 7001's withbuilt in subs and I would never use them as large. Your best bet is to set all speakers to small and use the appropriate crossover setting for each speaker. for example Deftech claims my towers can go down to 18Hz (when pigs fly maybe) hey can easily g down to 30Hz but since my Onkyo 805 doesntgo down to that level (before swicthing to Large) I set it to 40Hz and I get great bass response. I always cross them over at a point belw the rated frequency response and send the rest to the subwoofer. For example my DT Studio 450's can easily go to 50Hz, i set them at 60Hz. Find out what your speakers can handle as far as bass goes and go up one crossover point from there. I agree Double bass is never a good thing even with towers that can handle it. The bass just gets too muddy when run full range.

I set the crossover at 50hz and things sound GOOD. Thanks guys!
One more question....If I run audessy with these new speakers will it choose the crossover point instead of the 50hz I set it at?

Audyssey does not choose any "setting" of xover for you, AFAIK. It's complicated, yeah. I've been led to believe that it's Onkyo's implementation that has to do with the setting to large. If Audyssey finds the natural roll-off to be at a point lower than 80hz, the Onkyo will assign as full range. Hence, even my bookshelf surrounds, if rather large, are designated at first as large. When I replaced those with bipolar surrounds, and smaller rears, they were set to 80hz and 90hz respectively.

As for the exact xover point to choose, it will come down to knowing your speaker's abilities more specifically, their interaction with the room, and perhaps even the volumes you obtain. Some folks xover at the roll-off, whereas others xover a full octave above. And many others some where in between.

So, to turn that long story short, "No, if you rerun Audyssey, the Onkyo will set your mains as large once again". Hence, you'll have to once again reassign the new xover point.

I think the main thing to avoid is raising satellite speaker's xover point by too much. Say, you have a Bose cube, and AS reads the rolloff at 250hz. If you wanted a 100hz xover, AS would never have calibrated for that range between 100 and 250hz.

Hope this helps.
