It all depends on the market
The "audio fad" was a long one stretching from 1965 to 1990 when the bottom fell out. The boomer kids started it, innovation with portable systems as tube switched to transistor helped in the 1970's. In 1979 the Sony Walkman rolled out to huge success with a quick follow up by CDs and car audio in the 1980's keeping the run going. The world economy took a dip in 1990, the boomer kids were having kids and music sales, audio gear sales and all that went with it peaked then fell. Once the economy picked up, computers were the rage followed by cell phones, smart phones and so on. Easy to compete in the 60's/70's for disposable income when you had a TV and your stereo--it became harder with VCRs and bigger TVs in the 80's. By the 90's, the computer came first, then TV, VCR/DVD player and cell phone...audio got the crumbs.
The transistor, the chip and digital drove the boom for 25 years. Any innovation in audio basically came from the movie companies (Dolby/THX/surround) and the telecom industry (MP3, streaming etc.) The audio companies went from innovators to adding features other industries created. This is normal in a mature industry, if you want to look at audio innovation, don't look at the consumer side! The pro side has done line array tech, subwoofer tech, monster amps, digital everything and so on. There is a demand for relentless innovation on the pro side because that industry demands it. Car audio sound quality and features have really taken off since 1990 so we have that.
The good thing about nostalgia products is it revisits older designs that work properly. The L100 and Klipsch Forte' III come to mind. The generation of 20 somethings grew up on little bitty speakers with little subs as the Bose AM-5 took over in the late 80's. They are learning why such "monsters" existed and learning how they work. All the marketing for the past 30 years has been smaller is better, smaller is "new" and so on... the big dogs with large horns, big woofers and very large cabinets were considered obsolete. Well, physics don't go obsolete so even though the big dogs cost a fortune, if there is a market for something larger than a coffee can--it will be filled.
I'm sure the new JBL L100 will sound much better than the old one... Samsung blew 8 Billion bucks buying out Harmon, they like JBL and want to build the brand. Could this be the first fruit of their union? Measurements will tell... throw us some spinorama action! Now that would be a good comparison, the Klipsch Forte' III VS the JBL L100--bring it on!
Sure beats the skinny tower, little box speaker stuff of the past 20 years... never know, it might be really good. It could open the floodgates for speakers that are as big as they need to be to get optimum performance (it could happen!) At least it don't have that horrid piano black shiny finish that reflects light like a mirror to annoy the heck out of you when watching a movie. A return to performance over style? Why not?
Time for AVS to get out the measuring gear... although a curiosity for me as I have no use for it, the thing might kick some serious butt...or not.
