In a couple of other threads on here and in some other forums I've noticed people doing it with a 1/6th smoothing. Looking at some peoples sub readings in a completely treated room I really don't think its that bad considering my room is an acoustical nightmare

Potential culprits I narrowed it to but didn't really examine that carefully:

1) The Amp i was using - this is a long shot but sometimes phase shifts in electronics can cascade and be offensive right in the sibilance region. Still, I doubt it was this because I think I heard it on different electronics.

2) The room is too reflective. With the flush dome tweeter, you've got a lot of >4-6khz content being sprayed around the room compared to, say, 2khz. That energy could be the problem. Experiment judiciously with room treatment, starting with possible ceiling and floor reflection points. You wouldn't hear these things close to the speaker, because it's being amplified by the room acoustics.

3) Baffle diffraction rearing its ugly head. If you've got the speakers toed in, toe them straight forward instead, and vice versa to test. Does that change anything? Do you have any coffee tables etc near-or-in-the-way of the speakers?

4) One tweeter is damaged and can't handle long excursions. It's a possibility... hopefully not the case though!

5) It's just the nature of the speaker design. Too much content bleeding into the tweeter's bottom range. That or the mylar dome tweeter is just not pistonic in that frequency range. Or Midrange driver breakup bleeding through. The speakers do use 5" metal mids with 2nd order crossovers, which might be breaking up right in the sibilance range. You can test by putting your ear on the MIDs rather than the tweeter and listening. But All-in-all I would give RBH credit as they must have spent time voicing these speakers,

6) It's not the speakers, it's the original recording. This is the real wrench in things, because you could spend hours chasing after a problem that isn't really in your room. I never heard sibilance on music content, rather on close-miked sports commentating.

Thanks eternal, I'll do some more playing around. I swear I never head any distortion from Live free or die hard before which is why I'ts bugging me so much. There could be a large explosion, lots of stuff going on and I don't hear any bit of distortion. However last night on live free or die hard at I want to say about 14 minutes in when he's in the apartment crawling under the window, he gets shot at and says "Sh*t" and it distorts almost on the T it sounds like. So I played that over and over and got my ear nex to the center and sure enough it sounds like it breaks up a little, even at lower volume so maybe its just recording..

If anyone else could comment or hast that blu ray and could tell me if it gets a little crackly there i'd appreciate it.. I can find the exact time later on today when I get home.

I'm not sure how much processing needs to be done lol....plug it in to test it and you'll see the amp is completely messed up. Send replacement. frown.gif

I will say that the rw-12d is sounding better. I can see a few shortcomings of it at certain peaky frequencies, but hopefully when I get them both set up and can use the SPL meter I can figure out where my problem area's are and find a way to fix them. I'd like to play with the x-over and hopefully be able to setting on 60hz. Not as easy to locate and not so close to the 110hz crossover of the mains 6.5's

I tell ya what though...for under $1,500, this is one helluva setup. biggrin.gif

Hopefully they get it back out soon. Audyssey sets your crossover to 60Hz? Mine is set at 80Hz for the fronts and IIRC 100Hz for the surrounds. And it sure is, every time I watch a blu-ray I find myself grinning like a moron... rolleyes.gif

You're in luck. I'll try to check that part of the movie later tonight biggrin.gif

When you said you played around with Audyssey after my post, were you talking about the issues with distortion/crackling that I was having? If not, I was hearing what I think is the same thing you might be hearing. One part I remember it always showing up is in the movie The Avengers, at the beginning, where she's being interrogated. She says a long line of stuff in Russian and the big guy starts talking...at that point/near that point I can hear distortion in his voice. Almost like a crackling/breaking-up. It's definitely from the tweeter as I pulled the tweeter and didn't hear it. Plugged it back up, put my ear to the tweeter and played the part again...heard it. I played a little with test tones, but never got it to make that noise so I'm not sure how to go about it. It's not just the center either because if you put it in stereo, it'll still make the sound from the FL/FR speakers so it's either something inherent to the movie soundtrack OR a tweeter flaw.

Just sent me a tracking number, but no info on it yet. Hopefully Friday!! Seems like they ship it here pretty quickly. I think it's in Mississippi so OKC isn't too far.

Yeah MultEQ XT usually sets my fronts to 60hz and now that I think about it it usually sets my center to 60hz also. Surrounds are 80/100hz (can't remember), but I switch the surrounds to 100hz since they're somewhat close to the wall and I raise the center to 80hz. I'm currently playing around with where I want the main/sub crossover. Definitely more feel and tactile presence with the sub crossed at 80, but I feel it can get a little resonance...y & peaky up there, but we'll see. Hopefully I'll have time to pull out the SPL meter soon and see what my FR looks like

Update to my little distortion problem:

So I was watching Transformers Revenge of the fallen (Just got the iMax version.. and wow those full scale imax scenes look gorgeous)

Again at the top of peoples voices, not so much overall I was hearing a crackle in their voice. It always seemed like at the end of a word, its really the oddest thing. SO I did what someone spoke of earlier and disconnected the tweeter on my center. Well looking at it, the tweeters terminals are marked, one is red I'm assuming for the positive. Well the Yellow wire was hooked up to this rather than the red/yellow striped. I remember replacing the tweeter on my tower and the wiring being exaxctly the opposite.

I opened up the drivers on the towers to confirmed and sure enough it appears the tweeter was wired incorrectly on the center.

I also decided to take the tweeter out of my right side tower (it was the one I had replaced because of a really bad crackle if you guys recall so its brand new) hooked everything back up and watching the movie skipping through some noteable parts as we speak and I no longer as far as I can tell hear that distortion at the top end of peoples words..

Funny thing is I havent swapped back but I don't hear any distortion from the right side toiwer either.. so im thinking that being wired incorrectly was causing some sort of distortion, whats even more intersting about this is why I just started noticeing it and not before...

Quite confusing
post #1835 of 3146
That is weird. I'll have to check mine out tomorrow or tonight and report back on that. I could be 100% (I mean I have been wrong twice before biggrin.gif), but I would think swapping polarity wouldn't change anything as it's essentially just a 180 degree phase swap, BUT!...I don't know lol. Being out of phase could/can cause issues. If I remember correctly, phase causes a "time/wave" shift that are different at different frequencies, but polarity swap changes the "time/wave" shift at all frequencies from the driver. Maybe we can get someone more knowledgeable in here from the forums and sum this problem up. I'd be VERY interested to see if you continue to not hear the distortion/crackling/etc that you've been hearing. Maybe i'll pull them out tonight when the girl goes to bed. She's about to pop with our little girl so she gets tired really early

Yeah if you could take a look and let me know how your are wired I'd appreciate it, to reitterate the Red w/Yellow on tab with red marking, yellow wire on bare tab..

I don't think the center out of phase can cause distortion of the tweeter itself per-say, usually when speakers like L/R are out of phase it can cause cancellation or a "distorted" sound from my understand. I recall wiring my old speaker incorrectly before and everything just sounded "off" was hard to describe..

However I do belive in correct wiring can cause excessive strain on the AMP, I could be wrong (just some comments I read zooming around) and if thats the case its very possible it was causing strain to the amp causing distortion?

I don't know.. I watched the rest of the movie and wasnt bothered or really notice that distortion at all,
post #1837 of 3146
Well that's good news for you lol. Hopefully you don't hear it anymore. I know that I have never heard it other than on movies, but I really wonder if it's because I'm streaming them instead of a hardwired blu-ray. I'll pick up that Transformers too and see what I hear. Any specific parts you remember hearing it and now you don't??

Not really it was through the entire movie, just seemed in most of the dialouge at the end of a sentance I would just hear it..

I dobut its due to streaming depending on how your streaming (if your playing direct vs transcoding, or if your using an original track)

my 1:1 blu ray rips sound/look just as good as if I pop them into the player. Hell even some of my bigger encoded h264 movies youd be hard pressed to tell a difference (audio is a direct rip regardless)

careful with this.

Depending on the physical placement of the drivers, and the acoustical order of the transition between those drivers (the crossover), a designer will sometimes swap polarity. The towers I believe use a 2nd order slope between the mids and tweeter at a rather high frequency, whereas I would expect the center to use a steeper crossover at a lower frequency - they're not interchangable like that!

You may have just set your system up with a big frequency response null in the crossover region.

Well I'm curious to see what ousooner comes up with his..

I can also run rew both ways and see whats going on.. Off the batt though nothing sounds off after changing it.
post #1841 of 3146
Very true Eternal. I'll e-mail EMP today and ask them about if polarity should be swapped on ANY driver on ANY speaker.

Shady, don't you have an RTA? Maybe I'm confusing you with someone else, but if you do then you could easily have it up and running to see what happens to the frequency response when you swap polarity on the tweeter. If EMP could say if any driver in any of the speakers should be swapped, that'd be really helpful.

Called EMP and spoke with Brian.

Apparently the towers are purposely wired out of phase, which is why the center wiring is in fact different.

Also asked him if he had any idea as to what the problem was and he said its very likely that its just the tweeter (I dident ask him anything else, very possible a bad batch of tweeters?) I told him I'd listen for the distortion in the speaker I switched that one tweeter to and if I feel it needs to be replaced he said just call back and he would be happpy to just sned me out a new one.

I'll wire back the center and do something listening and see if I can still detect it.

I have REW, don't have RTA

So the center channel tweeter should be wired + to + and - to -. And the towers, opposite?

REW is an RTA. RTA is just a "real-time analyzer", which REW is...but it also does a lot more. RTA is just the reading of your frequency response in real-time

I have been e-mailing Brian also (see below)

Yes and no.


In the e55 towers, the (2) 5.25" midrange drivers AND the tweeters should be wired "out of phase" (aka...with polarity swapped). The (3) 6.5" drivers should be wired normally (red wire to the red marked terminal). From what I understand all other speakers in the Impression line should be wired with "normal" polarity (red wire to red terminal; red/yellow wire to bare metal terminal)

BUT!

The actual speaker could be reversed when it was put together/made so the red terminal that should be POS. could actually be negative. Maybe they corrected for that at the factory and maybe they didn't. He says they do, but obviously something could be wrong and they messed up on a driver(s)


I believe there are ways to test polarity. Using a certain type of battery I think. Maybe an ohm-meter. Looks like I'll have to refresh my memory. So in short, it could look like your drivers could be wired up incorrectly per EMP specs (red wire to bare terminal), but it might actually be correct in that the actual speaker is wired in reverse.

Driver polarity can be determined by hooking a battery to the terminals of the driver directly. Use a small battery no more than a couple volts are needed even for large drivers.

If when hooked up with normal polarity red-positive black-negative to a dc current source the driver(bypassing crossover) moves outward then it confirms normal polarity. Forget this for dome tweeters, won't work afaik. The only way I know of for this is measurement software.

Driver polarity markings are just reference points. Crossover designers switch driver polarites for numerous reasons and often. First ask the designer if reversed polarity is intentional.

If the drivers were mistakenly mis-labeled I would expect the manufacturer(EMP) to have that exhaustively documented, if not that is a mistake on their part IMO.

As previously stated, a driver with its polarity unintentionally swapped would have a sharp null at the crossover frequency and would be easily observed and corrected with measurement of the speaker's FR.

Thanks for that

EMP has stated that reversing the polarity on the 2 midrange drivers and the tweeter (on the e55 towers) ARE INTENTIONAL. I wonder how large that null would be at/around the crossover point and if it would be easily identifiable if the polarity was incorrect. I'll definitely open mine up when I get home and see.
post #1847 of 3146
So the towers should be wired out of phase and may appear to be wired out of phase, but the driver's terminals could be mislabeled so in reality, they're actually wired correctly, which is not correct wiring and then... I've gone cross eyed.

I'm extremely skeptical that the drivers would be mis-labeled. If that were true, and EMP was not aware, I would be highly disappointed. That kind of thing should be caught before the speakers ship, period.

If there is a 180 degree phase error(swapped polarity) it should be very easy to see on the FR measurement. How audible it would be depends on the crossover frequency, the room, and how trained person's ear is....... The null would be bad but maybe not as bad as some rooms interferance with loudspeakers so maybe not even audible at all to the average person in the average room. However if you a/b compared it you should be able to detect the improvement.

Honestly I'm surprised at how much tinkering discussion happens in this thread. Without measurement capability however, significant changes to a completed design is a learning exercise at best IMHO. It doesn't hurt to tinker and play though, I've done my share. biggrin.gif

Here is an example of a reverse null I pulled from the internets....

post #1849 of 3146
Quick Question, how do the EMPTek E55ti towers, E5ci center and surrounds compare to Polk? Has anyone had a chance to compare the 2? The E55ti towers look (from an amateur view) pretty similar to the Polk RTi A9 towers. I'm looking at either the EMPtek or the Polk RTi A9's with A6 center and surrounds. I'm also looking at the LSi M705's (as the center fits in my entertainment unit haha), are these on a whole different level? I know pricing is much higher.

Thanks! - John

I've listened to both, and while the comparision wasn't side by side

EMP pros

More rich and resolving in the midrange and lower treble, more accurate bass for acoustic music, more "believable" stereo imaging on most material. Overall just more balanced sounding.

Polk Pros

more "enveloping" stereo image on pop music, more bassy presentation on pop music with deeper extension.

Thanks! If I wait for the Emptek BF sale the cost between the 2 systems are pretty close (about $200 more for EmpTek) since I'm getting a deal on the Polks. The Polk system seems to have better surrounds (6" woofers and bipole/dipole) but EmpTek has a better center channel with the extra 2 drivers. The Polk towers are also 25lbs heavier but the EmpTek towers seem more efficient with power and may not 'need' and amp like the Polks.

Seems like I might just flip a coin lol.

Don't put so much stock in number of drivers and size, you need to compare the complete speaker. I have only heard the Monitor series from Polk and that is nothing like the RTi line, you could always demo the EMPs and Polks, and if you like the Polks, return the EMPs, if you like the EMPs, wait for the sale.

The EMP's will be neutral & laid back. The Polks will be brighter & more forward in their sound. Soundstage will be similar. Just choose which ever fits your music listening habits. If its heavy aggressive, then I would go with the Polk's, if its more laid back, then I would not hesitate to recommend the EMP's. Either way both sets offer good value.
post #1854 of 3146
Thanks everyone for the advice. I've been using a HTiB for awhile so I'm not sure I'd even know if I like laid back or aggressive. I do like DJ headphones more than the open-air style so I'd think that maybe I lean towards aggressive.
post #1855 of 3146
Depending on your space, consider that the Polk are also quite a bit deeper than the EMP. Since most companies recommend that speakers be at least a little ways away from the wall, the Polk are going to stick out a great deal more. Something to consider if space is ever going to be a concern. Otherwise, both sets of speakers are nice.
post #1856 of 3146
Hmm, my Polks were the exact opposite, I originally had the emps in the living room, but they didn't sound right. I switched them with the polks I had (50) which vented forward and they sounded better in that room.

I guess it depends on the room.

It definitely does. I prefer front ported speakers because it seems they can usually be closer to a wall. That's the only thing that I don't like about the EMP, is that they're rear ported.

budget wise, the polk rtia9's are twice the value for EMPs e55ti.

im saving my hard earned money 'til november. i hope emp tek will have that e55ti $477/pair black friday sale again.

Just ordered an A EMP ES1010I...has anyone heard this side by side with the Klipsch 12 inch sub and have any opinions? The EMP sub will go into my theater and the Klipsch will come up stair for my "mostly TV set up", replacing a 10 inch Klipsch Synergy sub, which really seems non existant in my 16x20 foot room.
