This morning finds me listening to the Infinity RS4000's that I re-foamed.
I'm driving them with my Torii with pretty good luck.
Vintage speakers driven by tubes always seems to work well.
The only down side I have so far is the woofer driver on the left one will sometimes buzz a bit. Truthfully I think it is something wrong with the driver itself, I keep checking my glue job and nothing looks wrong.
There was a spare foam surround sent with my order, I may get annoyed enough to cut the offending repair apart and try to redo my efforts to see if it improves itself.
To be truthful, I know myself enough to know that sometime later on today I will be back out in my hot garage starting over on this speaker.

By the way, as I'm listening to these speakers I am also reading up on the Amp Camp Amp.
I'm totally out of my wheelhouse here. I don't know nuthin' about no electricity!
But money has been spent and parts are rushing in from Italy and Massachusetts as we speak.
Time to man up and learn how to do this.
