Speakers sound SO much better, wrong mic or not audyssey did a hell of a job (from my ears point of view) eq'ing the speakers.


Chances are at somepoint tommorow I'll be playing with REW as I got my UMM-6 in from CSL, I'll take some measurements for you with Audyssey/and No correction at all.


My "review" to come in the next few days.

Sounds like a good first impression! Hopefully that center imaging improves for you.

Interesting question, unrelated to the EMP speakers. I recent bought a Yamaha Reciver (| RX-V373BL) to replace the old Sherwood. The Sherwood did not have hdmi, so it was obsolete. And, for the first time in my life, I have a blue ray player. Welcome to 2013!
Anyway, which bring me to question...now have the blue ray providing audio through hadmi, versus the DirectTV HD reciever, which was driving audio via opitical digital. The Blue Ray I watched last night (Resident Evil, not my kind of movie) had an amazing sound track.
1. Is that just a well mixed movie? Or
2. I am experiencing better Dolby processing with a new receiver? or
3. Is the SQ just must more detailed when hdmi carry the signal?

That movie uses DTS-HD Master Audio 5.1, which can only be sent via HDMI. Without HDMI it would come through in Dolby Digital 5.1.

Probably more of 1 and 2

As far as 3 goes..

Are you comparing the sound from your DirecTV Receiver to that of your Blu-Ray Player? As far as the AUDIO ONLY Portion, there should be no difference between optical and HDMI, as far as the receivers concerned it's getting the same 1's and 0's from either connection.

If you are comparing the quality, then the audio coming off of the Blu-Ray disk to the DirecTV signal than with 100% certainty the quality from the blu ray will be better. While DirecTV's audio is Dolby Digital, every "network" mixes the audio differently, its more compressed and often sounds too quiet, or to loud or a mixture of the two.

I have not, sorry. I was going to say "they offer the 30-day free trial"...but then I realized ....

1. I'm not sure if it's on these or just the Impression line

2. If you hack up your wall and don't like them, it's a little bit more of a PITA then normal, enclosed speakers lol

Does anyone listen to their e55's and e56 at anything like -15db to -8db (..ish)??

I had some spare time to figure out what the heck I was hearing during movies and it is in fact the tweeter. Sounds like a crackling noise. If anyone wants to try this on theirs that would be GREAT! One that's very easy for me to hear is in "Perks Of Being A Wallflower", when they're at the football game. First 15-20 minutes in. Crowd roars and the guy says a few words. Very distinct crackling. It happens on BOTH Audyssey and without any EQ. When changing to stereo (instead of native DTS soundtrack) it also happens on the mains, but not quite as prominent. Whether that's b/c it's divided into 2 speakers...I have no clue. It's definitely still there though and driving me crazy. My room is pretty big so most movies I'm watching around -8db to -15db it seems like. Sounds pretty great until this distortion/crackling/break-up/whatever you wanna call it happens.

What in the world should I do!?? redface.gif

I listen at those levels all of the time. I never heard this sound. If you are certain that it is the tweeter and not something in the soundtrack I would contact EmpTek to get a replacement tweeter.

This review and a few others say there are some problems with audio being too loud and distorted causing crackling. Specifically the football game. Good to know it's just the movie!

Good movie though!

Cadett, what happend to your graphs before the Audyssey measurements you posted? Unless I'm blind I can't find them. Curious to know if your speakers looked as bad as mine without audyssey in your room

I got REW setup with my UMM-6 mic. I checked and double checked everything a million times over...

Now granted, I think a lot of my post audyssey measurements suck due to the mic possibly not being calibrated right for my AVR, I have a replacement audyssey mic meant for my receiver inbound, but for some reason I can't help but think regardless of the audyssey mic being wrong or not there should be some sort of major change. Here is a graph showing No audyssey vs Audyssey ran freshly, I did not touch any of the settings at all because I wanted to get exactly what audyssey was giving.. Aside from a few DB here and there and the fact that overall the entire graph is 10db off as audyssey seems to set everything to 75DB

The thing that really confuses me is the really big dip around the ~200HZ region

Just showing the left channel, forgot to save the other measurements I did. Red is without audyssey turned on, blue is with it on.

I deleted the graphs for a couple of reasons. The main reason was really my first time using Rew & the new hardware. I wasnt confident in my approach & measurements. I would not be too concerned about it until you get the mic that is calibrated for your receiver. My mic was actually knocked off the table by my three year old & broken. So I'm currently waiting on a new one. If you refer back a few post, I explained how I improved my frequency response at the mlp.

EMP did not ask for me to send my old tweeter back, so I pried the grill off as someone else in this thread mentioned doing before.. Think I see why it was sounding distorted at time, there was "dent" in the fabric of the tweeter, not from a finger pushing, but a fine tool maybe sleeping during assembly or something?

So, I got the replacement Audyssey mic in from integra... Same exact one I used from my friends denon.. Looks like audyssey dident do much for me mad.gif

I'm going to run it and take measurements again tonight just to be sure, maybe if im lucky theres just a problem with his mic.. rolleyes.gif

So I lied and it looks like Audyssey did do some usefull stuff. It took some digging around in the Setup guides for audyssey to find how to get the "target" curves to change and help adjust the frequencies. While there are some dips and frequency problems between the speakers, it is just a problem with room acoustics and layout. For example, the left speaker has the back walla nd side wall, where as the right speaker has the back wall and a big open space to the right side.

I have a lot of graphs, I don't want to publish every single one of them, so in a bit ill capture and post the LF/RF/Center + Sub with no correction at all, and then with Audyssey turned on with THX Music (I like the curve that gives, less rolloff at the higher frequencies, I like a tad bit brighter sound)

If you average them both, it doesnt look like much has changed aside from it leveling out the low end with the sub and the high end, but if you look at each individual speaker, while theres just some spots thats just bad room acoustics, it made a lot of changes.

I tried moving my speakers aroudn quite a bit, but everytime I fixed one dip or spike, I made another worse.

Here is just the averages of all 3 speakers plus the subwoofer, when I get a little more time, I'll break it down channel by channel.

No Audyssey:


Audyssey with THX Music Setting:


Also, while the low end looks stupid in the average, my subwoofer went from basically being a giant spike up to 50hz and falling, with audyssey it levels it out much better

My room layout is the same way. Left speaker is wide open to another area, while the right speaker has a wall about 7-8' to the right. Not a huge difference, but I could see that Audyssey did a good job of correcting.

It still looks pretty good before, but the after looks great. A few problem areas, but I'm sure you'll get those figured out since you've got a mic now and can play around with room treatments (if you wanted), etc. The sub might be a little hot for me, but overall looks good. Looks pretty close to the MS-8 target curve I use in my car. Nice work!

Are you still enjoying them? How do you like both movies and music with Audyssey vs. w/o Audyssey?

It kind of depends on what I'm listening to.. I've been keeping Audyssey on the THX music setting so theres no as much rolloff on the high end, I need to play back and forth more, I have a feeling with louder action movies with the volume cranked up a bit im going to want to use the Cineima setting.

With music, It's kind of a tossup, someimtes I prefer the sound of "direct" and sometimes I prefer it with audyssey on

I captured all the graphs for individual channels, I'll try and post them later tonight.. The center is probably by far the worse speaker in regards to the frequency response, even with audyssey its somewhat all over the palce

Audyssey Flat (music) adds a little too much on the top end for me. I use normal Audyssey (movie curve) when listening to music (always in stereo of course). Going back and forth between the Audyssey and no EQ, I prefer MultEQ XT 99% of the time. Not to say that these speakers are bad without EQ...I don't mean that at all. They're just a tad too rolled off on the top.

Are you listening to music in good quality formats? FLAC, WAV, etc. Bad in = Bad out

I'd be interested to see your center graphs. It shouldn't be THAT bad, so maybe you've got some resonance issue, room issue, etc.

I forgot to add that I haven't had time to play around inside the cabinets to see if I can deaden them or make them more inert. Hopefully this weekend! I might pick up some polyfil and see what it does to the sound

Oh without a doubt I think its a resonance/room issue, I dont blame the center at all.

and yes I listen to my music in .FLAC format.


Interested to see what you come up with to sturdy the speakers up a bit.

Well...decided to re-run Audyssey when I got home just to see if removing the tweeter grills would have any effect on the EQ. I haven't changed anything in the setup. The only thing that changed was obviously the mic placement, but I used the exact same procedure and rough location for each step (1-8).

Front Left
Before it was +2.5db @ 8kHz and +3.5db @ 16kHz
Now it's +5db for both!!

Front Right
Before it was +4db @ 8kHz and +5.5db @ 16kHz
Now it's +6db for both!!


What the heck. I'm not a big fan of boosting the top end more than a few db's as it likely introduces distortion. I am definitely NOT okay with a 5db and 6db boost up top. The entire bandwidth (for EQ purposes) the tweeter covers has been boosted on each FL, FR and Center. I understand my room is rather large and open, but that's a little excessive. I still have that massive dip at 250hz and 500hz that needs a +4.5 to +5db boost from the center. It does sound slightly different than the FL and FR. A little more "bloated" if you will.

I'm beginning to wonder if something isn't right redface.gif

How high of frequencies can you hear? I took a hearing test about 4 years ago and I was able to hear 17khz: http://www.noiseaddicts.com/2009/03/can-you-hear-this-hearing-test/

But now I am only able to hear 12khz. Getting old sad frown.gif

It's not me, it's Audyssey redface.gif

MultEQ XT is boosting these frequencies based on what it hears. I already thought it was a little too high and felt like I could hear distortion when around -15db or higher on the AVR from the tweeters. It boosted the top end even more this time around with the EQ. The tweeters definitely work, it would be fairly obvious if they didn't, but to boost frequencies this much is a little concerning.

On the bright side. From the graph it seems the EMP speakers are just right for me tongue.gif

Just received my new E55Ti Tower Speakers and matching center yesterday. So I thought I would check in and ask everyone if there are any recommendations on speaker wire and banana plugs??

I'm considering these for my banana plugs...
