Anthem MRX Receivers - 300, 500, 700 Owners Thread & Tweaking Guide - Page 247

Aux Right: -2
Aux Left: 0
Sub: -10

Also, in the targets, I took it upon myself to boost the room gain from 1.79... to 2.5. I also noticed that i get a fuller sound and more bass with dolby volume on. Shouldn't it be the other way around? Thanks for your help!

I currently have an HDMI matrix box (4 in, 2 out) that works fine (my current receiver has no HDMI) but I'm concerned with the potential for handshake issues by placing it in the path between the MRX and my 2 displays (I have a projector that I don't want to fire up for briefer viewing sessions--I use a small flat panel for that purpose).

Does anyone have any experience with using an HDMI splitter and an MRX receiver?

How attached are you to that speaker? I am sure a more substantial center speaker would give better results (and you have plenty of space on the console below the TV).

The idea of running without ARC is silly. Your issues are clearly not with ARC. Let me state again, your center simply does not go down any lower (in your current envionment at least).

Keep in mind that the first line ARC draws in your graphs, the red "measured" line is done without any influence from ARCs corrections. When ARC runs its sweeps, it tests all speakers from 20Hz to 20kHz and then displays what it measured as the response of the speakers, as received at the listening mic... so your center was tested with sound well below what you are seeing in your graphs. The speaker simply failed to reproduce anything down below 200Hz or so.

In fact, based on the way the speaker doesn't slowly decay but quickly drops off, it looks as though the center has a high pass filter built in and simply is incapable of going lower. You would see the same thing if you were to measure the speaker with any other amp using any other measuring tool.

At this point, I have two more things I can do to improve the sound to my liking.

1. Raise the center up another couple inches and tilt it slightly(per the suggestion of a forum member)

and/or

2. Place some sort of cloth or towel on the cabinet to help absorb some the reflections.

If neither of those things work and the center is working correctly, then I will consider moving onto something else..

those specifications are for tower speakers and not the center channel. Also, they are meaningless as they don't provide a deviation from reference level. All they quote is 16Hz - 35kHz which in fact could mean +/- 20dB at 16Hz (or +/- 1dB for that matter).

Cheers.

It says the Frequency Response is 60hz-35kHz??

Correct, I was confused too but scrolling further down showed the results for 50C. Based on ARC measurements it cuts off much higher than 60Hz. It should be -3dB at 60Hz, but it looks like it is like that a bit under 200Hz.

The speaker has two 4.5'' woofers. The cabinet is not large but 200Hz is really high. In comparison, B&W CMC center has two 5'' woofers and -3dB point at 55Hz (that it actually hits in the typical room :-). I think given smaller drivers and cabinet, you would get good results if 50C managed -3dB at 80-90Hz, but 200Hz is an octave higher.

Yeah, but the problem with this is that it doesn't say it is +/- 3dB at 60Hz. Therefore the speaker could actually be within specs at -17dB at 60Hz. Sad but true.

Cheers.

If you have the 50Cs... I would talk to your dealer. They are not performing anywhere near spec... even if the spec is a 6db drop and not a 3db drop

Also, the 50Cs have optional feet... (don't know if they were in the box or you have to purchase them seperatly) but they could probably be used to replace your stacks of CDs

I have been listening to several different demos and the dialog still isn't sounding as good as I would hope from a much hyped speaker...

I believe it is taking time for projector to display the picture. Is there anything that I can do to get picture and audio at the same time as possible?

Does anybody experience similar problem?

Dual voice coils help keep response linear through driver travel, and class D amplification allows high power from a smaller and lighter package.

Just thought I'd share this, and sorry for going off-topic with the subs but it's all about field cases of in-room response and correction: At shows we normally use two subs up front and two smaller ones at the back for the multichannel demo. While PBKing the back ones at the last CEDIA I was amazed to see that the little Monitor Sub 8s were -3 dB at 20 Hz. I'd never heard of this model and asked a co-worker what was going on with response like that. Of course this is at PBK test sweep level and like most well engineered subs the louder things get the more it rolls off the low end (aka party mode) but still, compare this to the slightly larger entry-level PDR-8 from which response drops like a cliff below 50 Hz even at ARC sweep level. The Sub 12s were flat down to 20 Hz after PBK correction. All were placed in corners (plywood walls, for what it's worth). We used the same equipment at the first annual TAVES in a hotel suite and here's where I'm going with this: One Sub 12 was flat to 20 Hz like at CEDIA whereas the other was 6 dB down. Each Sub 8 was half way down a side wall, and one was down 5 dB and the other 7 dB. Location, location, location! Unfortunately at TAVES the room was shared with a 2-channel system and display area and we couldn't reposition any subs to improve low-end response, especially with the Sub 2s taking the best spots at the front.

Speaking of, the only way to have it all, i.e. undistorted subsonic frequencies at very high output from an enclosure that's smaller than most furniture is with something of the six-driver Signature Sub 2's calibre -- but positioning remains just as important.

Send him the following URL: www.avsforum.com/avs-vb/attachment.php?attachmentid=227972

Tell him that based on the specs listed in the manual (60Hz - 35kHz), we would expect the speaker to be about 3db down at 60, but this shows more like 17db! And that that is using the rear wall for boundary gain. When the speaker was not tight to the wall it was even worse!

My apologies for mis-remembering the Paradigm product line.

Good info about the transition from servo-based to DSP controlled subs. Actually it's pretty amazing that things have gotten to the point you can readily put that much computing power INSIDE a subwoofer.
