They are still great speakers, I had them starting in 1970 and was a dealer for them for years. The STC-Coles super tweeter and Celestion HF 1300 tweeter are no longer in production; Spendor has switched to Scanspeak in later versions of the speaker, which is still being made. They will not play all that loud but at least as loud as , say , a Quad 63. On voice they are hard to beat; when I had my Apogee Duetta Signatures and my SP 1s [later version of the BC 1s] set up together I spent most of the time listening to the SP 1s. Check the Spendor forum on line for further info.
