Hmmm. Interesting. If those harmonics exists, and I believe you are correct that they do, wouldn't they have been recorded when the music was played originally, and then the harmonic itself be played by the speakers. That is, the harmonic exists in the encoding on the disk, or mp3, or whatever it is, so your processor actually sends the signals to your speakers to play the harmonic as well as the actual note at 500K smile.gif

The flip side to that are not recorded, but are generated by the man behind the mixing board.

Wow! Great list NicksHitachi.

Yeah, that is what I meant to say in my post:p

I am considering DIY and I am not trying to hijack the thread at all. But, maybe 235 would like to know what DIY speaker you are building.

I honestly did not think human hearing extended beyond 20K at least appreciably so that is new info for me. I am curious to know how high I can reliably hear and more importantly what my ability is to pick out those frequencies amidst all of the other noise from the recording. There is an online hearing test around here somewhere but I don't know how accurate it is.

So personally I would go for below 20 if I had to choose just one because I know I can feel just fine. I think most people can hear to about 15-20. I would consider DIY subs much easier than DIY speakers and you could get to below 20 for a lot cheaper that way.

Again, my understanding only, I'm not an expert.....

I don't recall ever actually hearing the difference tones recorded. I've only experienced it live (both playing and listening). I did see a couple of 'net references that theorize that is has to do with how the human ear responds to the two tones. The recording mikes would not necessarily respond in the same way so may not pick it up.

And again if I recall from college, 22K is the limit.



And back on topic a bit...I'm surprised at all that there are speakers in these ranges. Maybe I'm not looking at high end enough speakers, but it seems to me that all of the speakers I've looked at are at least 20-20K, with some going down to 15 - 20K. I can't recall seeing any that only go to 15K.

Remember +/-3db actually means it could be down 6db, it just depends on where you draw the FR line. ;)

 

This speaker is specd to 100KHz +/-3db, but get your checkbook.  However it has relatively low sensitivity and would never provide 105db cannon blasts at the seated position.  Its still an awesome speaker, just not the tool for the job in HT.

 

Now This speaker is specd to 18KHz +/-3db, so theoretically it could(its probably not) be down 6db @18Hz depending on where we draw the line on the FR.  Now couple that with a db or two loss in the upper frequencies from firing through the screen, and you guys see where we are at.... pretty clost to 15KHz for a flat line.  However it can deliver the cannon blasts with enough umph to scare you(and your guests :P) and would most likely do admirably(but not perfectly) with music as well since this isn't a critical listening room and blah blah blah.

Some very fine looking speakers, Ill bet they just sound terrible! wink.gif

Oh I go week in the knees when I see those towers naked! Let me tell you they sound better than they look which is really saying something as they are beautiful speakers. I should know I own a set in the matte finish. biggrin.gif What did you do as your center and surrounds? I went with the matching center and the 170 SE as my surrounds. You will LOVE these speakers, a very honest and true sound and they will really rock. I have mine paired with a Yamaha Aventage 1010 and an Emotiva XPA-3......I don't lack for power. I topped it all off with a Rythmik FV15HP and I could not be happier!

Enjoy your new babies!

Fusion Jive from Roman. A few minor adjustments needed to the chairs but Roman has been great as everyone knows. Pix to come.

Same seats i'm looking at because of the shorter overall width, give us a review once you've had a chance to try them out.smile.gif

Yup, sound so awful my wife keeps telling me to turn down the volume. I can't wait to have a soundproof treated room. If a treated room really is just as important as the equipment itself things will be amazing eek.gif

Thanks RT, I just skimmed over your thread. Looks like we have lots in common with our equipment selection. Here's my center, not sure why Dave reversed the tweeter and mid positioning that he has on the towers but still sounds great...

Likely to get the tweeter up and away from any shelf or whatever your sitting on for diffraction mitigation. Always bring the center out to the edge of shelf so edge of shelf lines up with the plane of the baffle or slightly behind if possible.

Also to get tweeter closer to ear height.

That center is gorgeous too!

Do you think columns for my surrounds will have diffraction problems with a setup similar to below? That column isn't the exact plan, needs more bracing but might be very similar to what Brad did in his room. A contractor came yesterday and suggested I replace the 2x2's with a solid 2x8 cut on an angle. In order to save width in the room I plan on hanging the speakers directly on the wall.

....and here are the actual surround speakers. I chose these in large part because they won't eat up as much of my limited room width. Ascend's other candidate the 170SE are much deeper and require spacing from the wall for the rear port. I think I'll mount them horizontally to allow me to taper in the columns a bit more.

Its probably not that big of a deal but ideally those side slats of the column should be plumb with or slightly behind the baffle. Now will you hear it? Prob not but it probably causes a measurable diffraction/reflection artifact.

A bigger issue i would consider addressing is turning those surrounds vertical and angling toward the listener. Are you running the surrounds @90degrees or slightly behind?
post #168 of 544
Nick,

I think he wants to mount them as in the diagram so he can taper the columns at a steeper angle. I think in an ideal world you would want to mount them vertically and aim them towards the listener. I would guess that while not ideal you might not actually perceive much difference even if there is a measurable one.

I would however try to keep the edge of the speaker away from the edge of the slats as Nick points out. I would guess thought that if you are going to stick with the drawing then I would keep the orientation with the tweeter down as it is closer to the listeners ear that way.

BTW those Ascends are gorgeous, but I'm a little biased!

RTROSE

I'll try to get them as close to plumb as possible and maybe a bit more width to the column would also help? As far as positioning within the room, I'll have to see what bpape recommends. He's recently gave me the acoustic plan but nothing on surround positioning.

That's right I was placing them horizontally for the steeper angle on the column. I read a quote on the Ascend forums from the maker of these speakers that flipping them horizontally (with tweeter down) and angling down 5 degrees would not be a compromise vs vertical placement. Maybe a column like my contractor suggested would work just as well as the 2x2 framing?

Thinking of getting this SPL meter for future calibration:

http://www.radioshack.com/product/index.jsp?productId=12680845#

Are there correction tables for this unit? Do those adjustments get entered into this device or are they just adjustments that are manually applied?
post #172 of 544
Not sure if there are correction tables for that meter? The ones ive seen were black, had a guage at top, and a line out so you could send that signal to measurement software.

So what exactly were the "adjustments" that were needed? Also, how are you liking the chairs overall, etc?

I had a dented tray table and a couple of mis-aligned hinges on the armrests. Roman was very responsive to dealing with this.
I chose the Jive's because of the smaller footprint and the tray tables and storage. I'm very happy with them. I'm the tallest one in the house at 5'6". If head support is key for you and you're much taller then you might look at other chairs.

Very nice seating 235!  I have a sectional in my living room and its awesome to lounge on or entertain, but nothing says lets get busy watching a movie like theater recliners!  Period.

My Behringer amp that I will use to drive my 7 buttkickers. I channel on the amp was DOA. I had it repaired and it's now ready to rumble smile.gif I just have to wait for my new kickers. I returned the minis and ordered Advance model. Hopefully I can still drive all 7 with this amp.... Any suggestions on a small preamp to bridge the weaker consumer preamp output to the pro amp input levels of this EXP4000?

Whats the input sensitivity of the EPX4000?  Ive never had any probs driving a pro amp to clipping with most modern AVRs......
