Tannoy or Volti

For $16k, I’d look for some as-new B&W 803 D4s or maybe something from ATC. 

@charles007100 As a Forte-4 owner, let me tell you my experience. Shortly after purchase, I decided to open the binding post assembly to check for tightness, etc..

I found some connection "extenders’, i.e. small strips of stainless steel. These are used in between crossover wires and binding post wires. They have no obvious purpose other than giving some extra length, if needed (probably makes it easier during final assembly).

While open, I noticed the wiring was reversed. A red wire was on a black binding post, and black to red. I made the correction.

Your Fortes may have a similar condition. It could be worth checking out.

Mine sound quite respectable and in no way sound "muffled".

BTW, I replaced the SS strips with solid copper "just in case". After lots of effort (fabricating copper strips) I realized I could have just extended the crossover leads directly to the binding posts (duh!).

P.S. Regarding Klipsch Forte-4

For a good speaker cable connection (to binding post), use ONLY banana plugs. Spades can be used but anything more than "finger tight" will cause the inner nut to go loose. I think this is why I open the binding post plate in the first place,
