Audio issue

Have you checked you Tull's "Classic Case"? It is amazing the dynamic range the symphony adds. It's and older album, from about 1985.

My wife is a huge Moody's fan; it's cool what they do with symphonies too. Of course, they do the synthesized stuff too. Mike Pinder lives over in Auburn, not to far from me and _RAT_. He still has the early Melotron the Moodies used on the early albums. He writes childrens books, then puts them on audio tape with accompanyment from the Melotron.

I checked some oneline sources(Amazon, Crutchfield). It is amazing the number of active subs that are out there. If this is not an easy fix, then I'll probably go that route.

Speaking of the M'blues... One of their favorite songs of mine is "I'm just a singer in a rock-n-roll band'.

Awsome performance piece.

Of course 'nights in white satin' is classic too.

lets see.. other good / odd music.

'The night chicago died' by paperlace is an interesting piece.. and another favorite of mine, as well as 'hair' by the cowsills, 'convoy' by c.w.mccall, and 'Conquistadore' by Procol Harum.

I checked the sattelites; each was about 4 ohms. I checked the passive sub; one channel was about 5.6ohm on the input and output. The other channel was about 4M ohm. Something funny is happening there.

Keep in mind that is it not DC resistance that the amplifier is dealing with. It is AC impedance, and you cannot measure it with a DVM. If you have a coil or capacitor somewhere in the crossover that is fried, it will not necessarily show up with a DC measurement.

... probably a leslie.. etc.. Soundguy

That sure triggered a memory. My dad went to high school with Don and Bob Leslie (and kept in contact till their deaths). Later in life, my dad took a job in the R&D dept. of ElectroMusic, the Leslie speaker plant, in Pasadena, CA. He was awarded a patent for, what I remember them laughingly calling, the monkey motion machine. I think I was only about 10 then but, IIRC, the device created a truely random rotational speed for the speaker rotor (or something like that).
In case some don't know, the guys were truely organ freaks. The Leslies built a pipe organ on the premisises as a basis for the speaker design. The legendary George Wright would come by and tune all the pipes, by ear, every so often. The goal was to create a speaker that would be as close as possible to a pipe organ sound using a common electronic organ. Thus a rotary speaker. When the rockers got ahold of the speakers, things kindof changed at the plant. Of course sales soared but it wasn't really the same for some of the old timers.
Eventually, the pipe organ burned down, Electro Music was sold, one of the brothers retired to count his money, the other brother only kindof semi retired and continued his long time business of manufacturing the foam speaker rotors.
Cheers!

100% understood. A DVM is only for very basic checkout. At least on a speaker, it gives a basic idea of the winding resistance, but not the actual AC load. And, every resistive divider, coil, and cap with throw a kink in things.

I was looking at some stuff at work yesterday. One way, I got a stable ohm value; reverse the leads and you could see the value change as the polarity of the leads charged a cap.

Of all the bands I have seen multiple times, the Moody Blues have consistently put on excellent shows. I think I have seen them six times with my wife. A few times were in Lake Tahoe, at Ceasars. It is a smaller, intimate venue. They have been just great every time. Even with the new floutist. And yes, they crank it out good on "Singer".

I purchased the CD of the Moody Blues live in England, don't remember the album name. It's one of the latest recordings. I heard a new tune on there called English Sunset that will give your speakers a workout. The Moodys were/are indeed one of my favorite groups. I even have some of the Justin Hayward "Bluejays" music. Its been great with computers to compile my collection of "speaker rattling" tunes. Be it Erich Kunzel to John Jarvis to the Eagles to Jethro Tull (was he really the inventor of the plow?) Its when having a amplifer with lots of headroom a benefit. My old Yamaha R9 would have clipped a few speakers by now had I not upgraded. Robert, check out Audioholic for lots of information/opinions about subs.
