Using auto sensing circuits on amps/subs seem to be more trouble than it's worth. They rarely have sensitivity adjustments, and they don't come on when you're listening at low levels.

During this election season, I'm going to be on the "pro-12V trigger" platform. If that's not an option, I'll get the electrician to install me a power fed 'sub duplex' that I can relay on/off. Or, get an extention cord.

I'm against leaving stuff on all the time; it's wasteful. I know my clients can afford it, and they know it too. But, they still don't like to waste money. I don't either, unless it's on adult beverages or $4 golf balls that will surely go into the ocean on the first swing.

I also do installs in homes that are not occupied for months at a time. It would reduce the life of the unit, generally speaking, to leave it on all the time. For someone who uses it daily, leaving it on all the time may not be a big deal.

New Product Idea; 'Steriodial' power supplies for high current amps. Torroidial design floating in a condensed cooling gel comprised of steroids and baby seal fat.

All these fancy ingredients. Sometimes the truth is strange too.
Some Yamaha Ye Olde paper cone speakers were produced by pulping the shavings left over from thier piano manufacturing, then soaked for a full year in some lake that had particular chemical properties. The pulp was then formed into the speaker cones.

The best one by far i think were the Technics speakers that had large blue flat panels for the Bass and mid Bass drivers. These panels were produced from a composite material comprising of crushed lobster shells and the wax off cicada wings. They sold for about 80K 15-20 years ago. I kid you not.

Simon,
This is quite funny, but I have to wonder how you ever realized this??

Do the fine US, Canadian, British, German, and Danish loudspeakers get decent representation in Australia??

I haven't even LOOKED at a Japanese speaker in probably a decade!!

OK, the exception is the Yamaha NS-10.
Even though they are the ubiquitous meter bridge monitor, they seriously lack detail...

My favorite one was the ear-shaped speaker Yamaha marketed in the 70's, based on the supposition that if an ear eminated the sound an ear heard it better (no kidding).

Do you guess the ear speakers were made out of actual ears? Taken from where? (Now I'm kidding.)

No, c'mon now. That glue stripe in the woofer was a fine bit of detailing!

The NS-10 challenges the Bose line for the most overrated speaker in history.
