I thought many of the better consoles were fun to listen to! And by "fun" I don't mean accurate, but rather bass for example that could be rather boomy though quite powerful* and highs that were "laid back" and not exactly full of detail. So yes, lots of sonic coloration. And stereo imaging capabilities? Forget about it! :toothygrin: But despite all that I enjoyed listening to many of them, fully aware they weren't anything close to even a pair of entry-level Boston Acoustics. But as a secondary
sound system IMO they can be a kick to have around.
That being said...........
I agree with other members and personally would not recommend using a typical console's TT to play your vinyl. Those heavy-tracking (usually) ceramic cartridges with those fat styluses always seemed like a dull icepick was being dragged through the grooves - no thank you. But if the TT utilized a magnetic cart - usually much lighter tracking force and more sophisticated stylus - I might think about it.
The speakers: most consoles' woofers almost always operated in an open-backed configuration & replacing them would be tricky since few woofers nowadays are designed to be used that way (i.e. stiff cone suspensions are needed) except for musical instrument woofers, which aren't exactly optimized for music playback. Plus console woofers were usually designed to be crossed over at rather high frequencies, IIRC usually from around 4kHz or higher - most modern 10" to 12" woofers can barely make it to @2kHz, if even that.
The tweeters probably still work O.K. but will very probably not sound that way because the super-simple crossover - which almost always consisted of a lone capacitor - has aged badly: capacitors that old, particularly electrolytics, will most probably have changed chemically and/or literally dried up. This almost always results in reduced output from the tweeter, and sometimes NO output. Plus the xover frequency can change too, again altering the system's overall sound quality.
BTW speaking of subwoofers: while not a true subwoofer, Motorolas and some other brands sometimes included a separate woofer with its own amplifier specifically for the lower notes. Here's an excellent example
. And IIRC some better Magnavoxs operated their woofers in styrofoam(!) "enclosures" to improve their sound.
* most consoles have amps with only around 10-15 watts per channel max, but their woofers' cones are so light and basically dipolar in nature, not to mention even the 12" and 15" versions probably barely made it to 50Hz, the system can produce volume levels easily loud enough to fully prevent any normal/non-shouted conversation.
