Spendor S20 Any good?

I've since received an email from Spendor. Spendor provided the original Spendor 20 product brochure. Also, according to Spendor: "Historically, S20 is the forerunner of the Spendor SP3/1 loudspeaker (which started life as a sealed cabinet loudspeaker)."

The Spendor S20 was the most musical, most satisfying speaker Spendor ever made. Back in 1990, I would sell 200 of them in a year. Sadly, their replacement the 3/1 lost the magic of the S20.

It is 2024, and I bought a pair of these from Reverb. The treble and midrange are exquisite. You can tell that someone spent some time working on this design. At any rate, there is no bass, whatsoever. So I put them into my closet until I bought an Audioengine s6 subwoofer. I had never owned a sub before and could not get this to sound good with various speakers. So I mated this sub with these speakers and bam!! I was smacked with the most beautiful 😍 sound arrangement that I've ever heard in my room. There are other speakers that have more detail/etc. More this and that, but these just hit a spot that I can't figure out?? Just 👌 perfect.

Gene would know. Glad to read about such a legend
