Spendor Bc1 what is a good upgrade mod ?

I agree, I wouldn't sell the BC1's. Installing 4mm white Marigo dots on the corners of my cross-over circuit boards provided a nice improvement as well. Actually I only had enought dots left for half a treatment to the cross-over boards.

Dear Phillip,
Hi. I wrote to you about the TDL Monitors before, and I just saw your latest post. I certainly respect Spendor, as I mentioned, I own a pair of SP100 now. Still as good as the BC1 was, that is pretty old now. I will tell you this for what it is worth, of all of the speakers I have owned and sold, these are the ones I wish I had kept. They are good for all music, but you will absolutely love them for jazz and especially classical. Don't let anyone tell you that they are boomy or must be used in a big room- not so. I used them in a 11x17 room with great success. And despite their ability to produce low bass, they don't infuse all music with bass that isn't there.They have a great "soul" if that can be said of a speaker, and if you can afford them, put the BC1s away and do't look back. Let me know what you decide.
Good Luck, John

Hi John
Thanks for the e.mail and advice it is much appreciated , the hifi shop where the TDLs are for sale is a place i have been dealing with for some time and the owner really seems to think that a more modern design is the way to go , i can see his point but hey the BC1s are a lovely sounding speaker so the TDLs are not to be overlooked , it could be for a sale figures but i dont think he would go this path as i have been dealing for many years with him and he see's me as a client more than a blow in of the street , its just hard to depart from the warm Spendor sound , i guess its like an old friend , i will post what i decide .
Cheers. Phil.

They have been sold so i may look at NHT ST4 or Triangle ?

All you need is a modern solid-state amp with lots of current to control those woofers. I love the BC-1s.
