From my perspective, there are no audio/sound experts on this forum. For a short time in my younger days I worked for Executone Systems, a company that sold and installed varios forms of audio systems for larger applications, hospitals, theaters, large industrial complexes, etc... We had audio engineers, all of whom were extremely knowledgeable, individuals that I would consider experts in the field of audio systems.
On this forum, we have individuals whom are somewhat knowledgeable, based upon their experiences with sound systems they've owned and/or used. I seriously doubt that anyone here has an ocilloscope with the peripherial accessories to properly analyze a sound system and determine how and what needs to be adjusted to provide the optimum sound quality for the average audiences hearing abilities.
Over the past half century I've owned dozens of sound systems from dozens of manufacturers. And, like many performers here, I used to believe that you need huge speakers to obtain the best coverage, while still providing sufficient volume levels to reach audience members situated at the outskirts of the venue. Now, I'm talkin' monster speakers, each tipping the scales at more than 100 pounds and requiring a refrigerator dolly to move them from the van to the venue. The quality of the sound back then was often loud and muddy - which is still the case with many conventional sound systems today.
Fortunately, Bose changed all that. The sounds are no longer muddy, the coverage is incredible, the falloff is minimal, and me personally, I don't have a mid-range problem.
Another noteworthy item is that has anyone noticed the number of Bose copy-cats that seems to have sprung up lately? They're coming out of the woodwork like termites, similar looking towers, similar looking base units, and more recently, modular units that employ similar overall sound dispersion.
When I did a marina Christmas Party here this past Saturday, it was an outdoor venue, at a Tiki Hut situated at the end of the dock, right next to the waters of Boot Key Harbor. I wondered why more people didn't attend the party than the 100 or so that was there. I got the answer the next day from some good friends that I had dinner with last night. They said they were going to dinghy to the Tiki Hut, but because they could hear the music so well from their boat, they decided to just enjoy it from the comfort of their deck chairs while drinking their favorite rum punch. Their boat was at least 500 yards from the Tiki Hut, and the volume on a single L1 Compact was never turned above the 11:00 O'clock position. And, they said the sounds were very crisp and clear, and they could understand every word of every song. Now, I'm no sound system expert, but that impressed the Hell out of me. Especially, when I considered that during my two-month voyage down here I stopped at a lot of marinas where bands used conventional sound systems and the only sounds that traveled across the water were the muffled sounds of the drums and bass - and I was nowhere near that far from the speakers.
Obviosly, this is my opinion, which is soley based upon MY, personal experiences over the past half-century of playing music in various venues. For now, and the not too distant future, I'll stick with Bose until something much, much better comes along.
