Loudspeakers with a wide sweet spot


Are there any loudspeakers with a wide sweet spot under $10,000?

Try to find some vintage Sansui sp-5500's MADE IN JAPAN. Here's a picture here below... www.theoldstereoguy.com/Web%20Pages/Museum.html .. Did you know that Eric Clapton ONLY uses speakers that has AlNiCo Magnets... www.audiocircle.com/circles/index.php?topic=52321.0
Thiel 2.4 have a wide sweet spot when set up properly and effectively "disappear."
This is a key design feature of the Daedalus DA-1...in addition to life-like dynamics, timbre, etc.
How can the sweet spot be wide? It's it the best spot, "The Sweet Spot?"

Is this a Zen question?
