just an FYI, now the cross overs are: RF-82s - 70Hz RC-62 - 80Hz RS-42s - 90Hz. LFE at 80Hz. That's all i can do that yield the cleanest and tightest sound. It's not gonna be that bad once the MFW-15 arrive. Thank you for all help.

Good to hear that at least some are reporting the bass is not muddy on their RF-82 without cross over. You must be running plenty of clean power on that RF-82 without crossover. Found a little culprit, replaced the cable with quality 12 gauge cable and it did sound better. set my cross over at 70Hz now and it sound OK. I need more clean power for them. Thanks.

In Stereo mode: When I lower my RF-82 crossover setting to 70Hz or 60Hz, it will sound muddy. Currently at 80Hz, it sound OK. Shouldn't RF-82 at least be able to perform at 70Hz or 60Hz? Maybe I just have high expectation of the RF-82.

Thanks for the reply, I am going to manually adjust everything when my MFW-15 arrive with SPL meter. I am just curious as what other people with similar setup has set.

Classic.....

Man, there are sooo many other better subs out there, even for the same price. Go to www.avsforum.com and you will know what i mean. Just to name a few, check out: HSU research, SVS, av123.com (the MFW-15, better yet get dual), Epik, Elemental Design, Paradigm servo. Good luck!

I have the RF-82s, RC-62 and RS-42s... To be honest with you, I am not impress on how they perform anymore. I am using a Onkyo 805 to drive all of them and in music mode, it was Ok and in movie mode it's a little better. Does anyone here have the exact same setup and please post your cross over setting as I would like to compare mine. Here is how is mine setup currently: RF-82s - 80Hz, RC-62 - 90Hz, and RS-42s - 100Hz. My LFE is set to 100Hz. That's the lowest I can go without it sound all muddy and unclean when I am listening music both in stereo mode and all channel stereo mode. I am listening at about -20dB and I am justifying should I get an external amp (Emotiva or Outlaw) or just upgrade the speakers. If someone has similar setup, please reply. Thank you.

I have the RF-82s, RC-62 and RS-42s and Onkyo 805 and here how I set mine: RF-82s at 80Hz RC-62 at 90Hz RS-42s at 100Hz LFE at 100Hz. That's the lowest that I can go without speakers sounding muddy and the hi frequency all unclean.
