How do the latest Bluetooth speakers compare with the sound of boom boxes made a quarter of a century ago? Has progress been made, has technology and digital signal processing made for better sound or are today's wireless speakers a step backward?
A few weeks ago I heard a bunch of portable Bluetooth speakers at the CNET NYC office, and I'm sorry, they all sounded different shades of distorted. They were harsh, grating, and just plain unpleasant -- and yet that hasn't affected Bluetooth speakers' popularity. Maybe the buyers don't know or care about what they're missing.
I never owned a boom box back in the day, but as I recall, some of them sounded decent, so I was curious to see how a vintage boom box would fare in a direct comparison with some of the better portable wireless speakers. A friend volunteered his 24-year-old JVC PC-X100 boom box, which sports a built-in CD player, AM/FM radio and a dual-well analog cassette deck.
I lugged it into the CNET office, and even before I started listening the PC-X100 had a clear advantage over most Bluetooth speakers. First, the PC-X100's speakers are removable; they detach from the central unit, so with the PC-X100 you can get bona-fide stereo separation. Most wireless speakers are one-piece systems, and their stereo speakers are just a few inches apart, so their stereo winds up sounding like mono. Even the high-end Naim Mu-so speaker, which is 24.7 inches wide sounds a lot smaller than the PC-X100 with its speakers spread 5 feet apart.
Not only that, you can replace the PC-X100's speakers with better quality speakers. I tried the boom box with a pair of budget-priced Dayton B652 speakers , and they were a terrific upgrade over the PC-X100's speakers. Even better, the pair of Pioneer SP-BS22-LR bookshelf speakers with the PC-X100, I loved that combination.
As for the wireless speakers, I gave them all a huge advantage, and played CDs on an Oppo BDP-105 Blu-ray player, hooked up with a cable to the wireless speakers. For the JVC PC-X100 I played the CDs in the boom box.
Boom boxes were hugely popular, and eBay listings for them are still bountiful, so locating a used one should be easy enough. Ask the seller questions. Make sure it works; just powering up means nothing. Does it play CDs or tapes? If the seller hasn't played the boom box, and can't vouch for its working condition, don't buy it.
