There is a Spendor mod for the BC1 to increase the size of the port and fit
a tube in it. Don't think I noticed much/any difference.

I went from BC1s to KEF Q55 but, apart from a brighter and less warm
presentation, I wish I had not. For classical/jazz and a good part of modern
light pop there really isn't much to beat the BC1.

If you're happy with them (presumably you have them on stands?) spend the
money on a holiday instead.

Thank you for your response. Yes I do have them on stands and have been
happy enough to have lived with them for 20+ years. The only flaw I
have ever noticed has to do with male voices (announcers on my local
classical music station) which seem to produce a very slight hissing.
But I have not set up my system to listen to announcers and if they
carry on too long, I would change the station or the source anyway.

I would not change these speakers lightly. I am only interested in
investigating what is available, and at what price, that would feel
like an upgrade.
