@kink56 , I notice that you are in Tucson. Maybe the wood panels of your Belle cabinets had dried out in the arid climate. The plywood on my old La Scala cabinet did not seem as dense as other newer cabinets, so I glued and screwed extra panel thickness to the sides before wrapping them with veneer.

I was just commenting on the #1 recording you play when you conduct a speaker demonstration, and you suggested that we listen to. I also think that your comments about the hump are valid, but the recording of the song is not the best choice for the demo, unless the point is to make the speaker sound unnaturally bad.

The background, or underground rumble on that recording caused the original recording to distort. Then when it is played back, the sub-sonic rumble forces the woofers to overwork, even if you can not hear it, causing intermodulation distortion which compounds the problem by creating another abnormal level of distortion. This may be worse than the above described condition, which I presume would be a clean recording.

I meet the nicest people when I go listen to music. A picture of symphony hall from our seats on front row center. The orchestra played the theme music from Star Wars. It was amazing.

Actually, it is a clever way to make any piece of audio equipment sound bad.

A hump in a speaker frequency response is a condition that can be adjusted down. The listening room probably has more humps and dips than that speaker. Using a poorly recorded song as a demo to point out a speaker's shortcomings seems odd.

Yes, you picked the song, and are using a poorly recorded song with a high level of sub-sonic noise and distortion as your favorite demo song. Why do you say that that? The electrostatic speakers with separate subwoofers are not distorting, they are accurately playing your bad demo. I used these speakers to avoid you saying I have a preferential bias toward Klipsch speakers.

My tape measure dimensions indicate that the K-horn mouth is more than 50% larger than the La Scala.

I listened to Birds again, this time on a pair of Martin-Logan electrostatic speakers. The recording has a sub-sonic rumble that is overloading the recording apparatus, thereby creating distortion to the entire recording. I can't identify if the rumble is from wind blowing across the microphone, or some heavy industrial noise in the background. Pleasant song, but the recording is noisy and distorted. The song is a poor choice for speaker demonstrations.

I just listened to Birds by Emiliana Torrini. I used headphones, on purpose. It is a pretty song and her voice is nice. The very low frequency rumble is in the recording, as you acknowledged. At times, the low guitar notes seem to be distorting or resonating, on the recording. I will try to Zero in on that later. If you don't hear that on your non-Klipsch speakers, I am happy for you, I guess.

Friendly people just trying to be helpful. Sometimes things are not understood clearly because the words we quickly type don't always convey the entire depth of our kind thoughts.

The La Scala is very symbolic for some of us. The first time my friends and I saw and heard them, it really changed the way we thought about loudspeakers and amplifiers.

You may have an ability to hear things that many other people do not.

Glad that you have the speakers you want. No offense intended, but I had trouble de-coding your first statement.

I go very often, so I intentionally choose different seats depending on the type of show. Last night I was front row center for the Music of John Williams. The theme music from Raiders of the Lost Ark, Jurassic Park and Star Wars. It was amazing.

The Walnut in your picture is beautiful. I also like the way you position the grain patterns on your veneer projects.

I listened to a symphony orchestra last night, and thinking about it now, I agree with many of the comments provided by @robert_kc and everyone else who say the goal is about finding the right combination of speakers and equipment for your room and listening choices. The process is almost always easier when you start with a really good set of speakers.

The last veneer project you did looked really good.

I think just one amplifier is equalized, and you the listener gets to choose which one. The prize money is probably not enough incentive for most people, but I wish someone would claim it just to prove it exists, and to become an audio forum Hero.

I had the pleasure of listening to the JBL K2 9900 speakers. Very nice. Also makes me happy that I have Klipschorns.

TRuE is the word for the new marketing theme. TRuE Audio. TRuE Realism. TRuE Entertainment. (I don't see how to overline my u with the keyboard)

This is for the subwoofer. Slightly different function than the main discussion of the previous posts

Can somebody please take the Amplifier Challenge and win the $10,000. I just want to know if it is real.

Please do let us know. I would really like to learn if certain AVRs are capable of band limiting when Bi-amp is selected. If you have time, can you try the procedure with your Onkyo again, just to rule out any possibility of an incomplete jumper connection?

Well I was supposed to be goofing off this morning, but instead here I am playing with my stereo equipment. Don't tell anyone outside of this forum. I just hooked up a pair of full range speakers to the HF assigned speaker out jacks of my Onkyo TX-NR1007 with BI-AMP selected in the Speaker Settings menu and it sounds full range.
