I don't get paid for this but sometimes when I discover  a great
 product I need I  will tell you about it.

 I am an opera fan and I am still in love with Maria Callas despite
 her being dead for years. She was blessed with an an extreme range
 of notes.

 There are very few hi fi sets that can handle her.

 Expensive (over $100) earphones are the best.

 I discovered a product that works very well. Not perfect but very
 well indeed.

 It is an Inland Pro Sound 2000 stero..

 www.inlandus.com.  Made in China of course.

 It is 100 watts  Frequency response is 70 cps to 20,000 cps.

 You are hardly going to believe this. It cost $12.95 U.S. Yes $ 12.95
 at Fry's. I did not expect much but I was stunned and amazed. Very
 few sound systems are better.  A very well engineered product indeed.
 The vast majority lack the high frequency capability.

 I am sure it uses modern integrated circuit technology but I have not
 had it apart yet. Too busy listening to Maria sing.

 You plug it into your computer, cell phone, tablet, cd player, what
 have you and play MP3's.

 These are the picture of her I pine over :-) Oh to be a billionaire
 when she was alive.

 Ok so if we are going slightly off topic, allow me to push it a
 little farther.  In an attempt to reproduce the lower octave most
 cannot hear, we are building 4 horns driven by 21" drivers.  Not for
 the volume (though it will do that well), but for accuracy.

 The first 70.5" of the 116.5" horn.

 That is amazing Chris. Good work. Are you back in Salt Lake ?

 I knew you where a brilliant engineer but I did not know you were
 into sound as well.

You are too kind Paul.

We are in Arizona now and don't foresee leaving, too addicted to the nice weather.

Dad's the brilliant engineer.  I'm just a persistent engineer; iterating fast enough to appear competent. :)

I remember watching large folded horns take shape in the shop as a teenager.  These were sold to local movie theaters.  I remember sitting in the theater as a kid watching Obi-Wan shut down the tractor beam over and over till Dad got the sound just right.

Here's a recent picture of the LSA:
