I would be inclined to run the HR-34 in Native mode. So, I'd like the 700 to just pass through the picture. I'm assuming that is possible.

Ok, I will try my best to get to 120hz cutoff by moving the damn heavy box.

Any comment on my other speakers correction? If ARC set the fronts and center to 60， shall I try 80 which can ease out the demand to my amp?

BTW, did you set FLAT in target to get that flat from 20Hz upward? And shall I set FLAT too?

Apparently I'm reselling 60s but it might take awhile and there'll be weeks, maybe months that I have both S2s and 60s.

So during the meanwhile, I'd like to use 60s as surrounds with S2 as mains.
But based on my room configuration, it is impossible to put the 60s in a normal conventional surround speaker position.

The best and only configuration I can have is placing both S2s and 60s at the front.
- For movie, I'd like to use 60s as surrounds but place them at the front
- For music, I'd like to play all 4 speakers, 2 left fronts and 2 right fronts

Does it make sense to use this way? Using 60s as surrounds for movie I think is pretty much straight forward. Just connect them to surround channels.

But for music, can MRX play 4 fronts? In other words, can I turn MRX surrounds channel to play identical as L/R fronts for music playback?

As for moving your sub... go to your local hardware store an pickup a set of furniture sliders. There are two kinds (in general), one has felt on the bottom for hardwood floors, the other is a really smooth plastic that works great on carpets. You will be amazed how well they work. I like the larger ones for most heavy objects.

I see you are in Hong Kong, but hopefully this will give you and idea of what I'm refering to:

+1. Your DD-15 is very capable of producing a very good frequency response as well. Jayray set the standard for others to try to achieve and many have. I have DD-18, and my sub's graph is very good also.



Yes, you can set yours to FLAT too.

Okay, I must be doing something fundamentally wrong. I just purchased an MRX-500 and after running ARC I'm not seeing any effect at all in the lowest frequencies. ARC's calculated response implies that it is applying filters, but when I use REW to evaluate ARC's effectiveness I see no change. Here's what I did:

1. Set speaker distances
2. Ran ARC measurements with 5 positions distributed around my seating area.
3. Left targets at default
4. Calculated filters
5. Uploaded to MRX
6. Setup 2 sources using the same input and settings (Dolby Volume off, Bass management set to Movie) with one having Room EQ on and one having Room EQ off.
7. Took measurements in REW from the center of the listening area for each of the 2 sources defined above.

Note that the peak at 33hz does not change at all, even though the calculated response in ARC indicates that it is attempting to correct the peak.

I'll keep experimenting with ARC to see if I can get this figured out, but I thought I'd throw this out to the experts in case there's something simple I'm not aware of.

Thanks!

Thanks for the suggestion Larry. Unfortunately I don't think REW is the issue. I have a full REW setup (calibrated ECM8000, XENYX502, calibrated sound card) that I've used on a variety of equipment. I can swap in an Audyssee based receiver and immediately see filtering happening in the lowest frequencies. If I make changes to my MiniDSP (with ARC active) I can also see those changes reflected in the FR (this was just a test to make sure I wasn't going crazy, no I don't normally make sub EQ adjustments after running any room correction system).

For the audio connection between the REW computer and the MRX I've tried both analog and HDMI (so from the MRX's perspective an analog stereo source, and a PCM 2.0 source).

Unless there's a magic setting somewhere that says "don't EQ the sub when x", I can only see there being 2 potential causes to my issue.

1. I'm experiencing a strange bug or defect, possibly unique to my setup, that is causing ARC or the receiver to not apply filters to the subwoofer.
2. Or, the receiver does not apply filters to the subwoofer when a stereo source is in use. Unfortunately I don't know of an easy way to generate a .1 signal for FR measurements to test this.

Anyone have any ideas?

I also have 6ohm NHT speakers. Hoping the 700 will deliver. One reviewer suggested the 700 struggled with 4ohm speakers he had.

You can always ADD external amps if you need them - WHICH I DOUBT YOU WILL
