Classe Sigma SSP and Rel S3 connection issue

I used both inputs which is recommended by Rel. I have my center and surrounds speaker Xcross over at 60 and 80 hz respectively. Then front left and right set to full. This is what rel recommend but I lost all mid bass. Then I change the front speaker to cross at 60 hz but still have the same results. Rel said this is what need to be done but Classe said no.

My main front left and right are B&W 804s and center is also B&W htm3s. They are cross at 60hz. There are no sub out cross over in the Classe. The Rel speaker level cross over for the main speakers is cross at around 40hz. When I listen to stereo music using just the main with the speaker level input, bass are fine. It is just that for 5.1 listening, even we set all speakers to small and let them cross over to the sub out, the mid bass is not that good. I think is something to do with how Classe handle bass management. Quite disappointed with the Sigma SSP.

I have tried that scenario as well,have all speakers cross at 60hz which mean only the LFE input and sub out are used, but mid bass is still missing. The only way I got full bass is disable sub out at the ssp and set main speaker to full. This way all the other speakers will send their bass info to the main speaker and the rel support the bass under 40 hz. However I don't like this setup because it will put an extra load on my amp. What I don't understand is why I still can't get full bass from the ssp using sub output and the rel LFE input, and have all speakers cross at 60 hz?

Just upgraded to the latest firmware last night 1.0.3.14. It doesn't seems to make any difference. I still have no mid bass when enable subwoofer and eBass in the speaker setting. I am using slope of 12, no Peq and no tone. How is your setup? Do you feel u got enough bass ? My Sigma SSP is brand new from Classe not a demo.

Can you tell me how do I PM you privately?

What Amp are u using? Can u also tell  me how do u config your setup. Did u set all speaker to small and croas at what hz? What level u set your sub to? And are u using eBass? I am assuming u are quite happy with the SVS. Did u connect the SVS using the sub out in the Sigma SSP? Thanks.

Hi I just brought an Svs sub and hoping that it will improve my movie bass performance. Can u tell me how is your ssp setting for watching movie. What is your cross over setting for each 5.1 speakers? Did u enable Ebass? Did u connect the sub out to the Svs LFE input? Did u set the Svs cross over to LFE (disable)? I have my front and center set as 60hz, surrounds at 80, cross over at Svs to LFE, and no ebass, but the sound is still not toy expection, thanks for your help.

Hi thank u for your reply. I brought the Svs sb2000. Finally I got to the right setting and sub placement now. I set my front and center to 60 hz, surrounds at 80hz. LFE connect to Svs. Now the movie sounds a lot better than using the Rel S3 sub. I can’t believe it is almost day and night. The Rel is good with stereo music but no way for home theater. The Svs sb2000 is like $1200 cheaper than the Rel S3, and it is fantastic and with tight bass. I appreciate all your help, if u can give me a quick procedure on how to use the REQ, that would be wonderful. Thanks again.
