A pity... I have blown speakers. (the higher end Lexicon)...

[larrycohen28]

The dealer could not find anything wrong with either the amplifier or the speakers in my car. They actually did the same tests which caused my amplifier to cut off and my speakers to distort on another Genesis, and had the same results. So, I decided to bring my car into a local car stereo shop, and they wound up installing a 12" subwoofer in the trunk, along with an amp to power it. The thing is though, they had to remove the 8" subwoofer in the rear deck lid because the trunk is so well isolated that none of the bass was getting through with it installed. So now we are trying to tweak the output from the new subwoofer and the rest of my system. It's proving tricky because the sub is causing a lot of rear deck lid vibration. I may have to wind up putting some sound dampening material under the rear deck lid, except of course where the hole is where the 8" subwoofer used to be. I don't know if this is going to work out, but if it doesn't I'll have them put the 8" subwoofer back and I'll be out some cash for all the labor involved.

Can you audiophiles teach me something...I think I may have a problem, so I'll describe it. I'm not knowledgeable on these things.

Sometimes, at random, and not frequently, it seems the sound I'm getting from the Lexicon system seems to instantly "change". It doesn't seem to matter if I have it on good old plain AM talk radio, or on XM channels. I still hear the program, but it sounds different. Maybe like I'm in a barrel or in a tunnel, for description's sake, best I can think of. Not bad sounding, but different to my ear, and happens instantaneously, when it occurs.

I've gone into settings, and made sure surround is checked, I keep the treble, bass, and the speakers pretty much in the middle settings, maybe one or two notches either way. And I do not play music too loud.

Is this "dropped speaker" or "cut out"? I mean I still hear the program, it just sounds different. And I know I could not get it to happen if I took it in someplace like a dealer or a radio shop, because of the random occurrences.

When it happens, it seems to stay that way. I then wonder why, and go into the systems and check the controls, like I said , for surround, and positions on the bass, etc. Then it seems to get back to what it was. And if i didn't change anything, I'm not so sure the difference isn't what it was supposed to be like in the first place!

(I know what you're thinking....what is she doing with this system since she clearly doesn't appreciate what good sound quality should be, in the first place)!

Hey, I'm in it for the air conditioned seat!!!!!!


Thanks for any advice you can give little Acey!

Sounds to me like you are simply losing reception and then getting it back. I didn't see that you are complaining of this problem with CD's or MP3s, so that's my guess. Happens to me on FM and XM all the time. Nothing you can really do about it.

Agree. And going further, it's probably HD coming and going on AM/FM. Happens to me all the time. But the same shouldn't be happening with XM. You either have a signal or you don't.
Acey, are you sure it happens on XM too?

Yes, that can be annoying if the station is HD and it toggles between AM/FM and HD. The only way to fix that is to force HD off in the options.

There's not a lot of a difference between XM and the ground FM repeaters for XM (which the tuner falls back to if it loses sight of the satellites for longer than the stream has been buffered), so I agree that it's usually an all-or-nothing proposition.

Acey, is this happening from time to time on a cd? Or your axillary input?

Enjoyingsilence....now that you mention it, no, I've not put in a CD or Ipod....strictly the radio and XM.

With HD Radio, the HD stream can drop to SD (normal quality) from time to time, then go back to HD, causing a "echoy" (spelling?) sound in the transition either way.

With XM, (not including ground repeaters, which aren't AS common, to be honest, they do exist tho)... not to get TOOOOO technical, but atmospheric conditions can interrupt the stream to your receiver, disrupting the bit-rate just so, causing a change in sound quality.

Combine either of the above senarios with the Logic 7 Processing, can cause a change in the sound field algorithm being used, causing you to hear something different, in an instant. Logic 7 Processing is built into your amplifier, it is known as the "surround" option, in our menus, for Genesis' featuring the Lexicon systems. For more information on Logic 7 Processing click on the links at the end of this post.

The reason I asked about your aux input, or a cd, is the same thing (re: Logic 7 Processing) can occur with those as well. Any change in the tonality of a song being played via cd/dvd, or your aux input, can cause the amplifier to re-position the sound field, in an instant. You'll hear it just ever so slightly. Someone's voice may be more clear on the front center speakers, percussion may be more vibrant on the mid range, than the front bass, certain ranges (measured in Hz) for lower sounds (bass) will be forwarded off to the sub. Sounds determined to be coming from the rear, will be played in the rear of your vehicle... and will be amplified just a tad, to simulate the surround experience. This can happen even with a 2 channel (left + right) source (your average cd is 2 channel, so is your mp3 player input, and the USB input). DVDs can be 5.1 or 7.1.

Logic 7 in a nut shell is designed to simulate a surround sound experience (in the case of the genesis, I believe a 7.1 (front left, front center, front right, rear left, rear right, "rear center" + subwoofer, generally)... from a 2 channel source. And can arbitrarily adjust the sound quality to achieve this.

As I said, when it arbitraily adjusts this, you can hear a change in tone, whether from XM, FM (HD FM), CD, USB/Aux In, etc...

Hope this helps.. sorry if it was long.. trying to cover my bases, and make sure this post is informative.
