speakers with balls

You guys are amateurs...

If you want speakers with Rad 'Nads, combine the Tannoy Westminster Royal Gold Reference with a Wilson Audio Thor's Hammer sub-woofer.

Then put on Black Sabbath's Paranoid Album, and turn it up to Eleven.

Steve Guttenberg tested the new-ish Forte III and concluded that although it didn't outperform his reference stuff in detail or something, it outperformed them all when playing things loud. There ya' go.

250watts going thru horns would make my ears bleed!
big no on the Maggies-
consider a 4 ohm Floorstanding speaker like Dynaudio with the SPL around 86-89. I have a pair of the Contour S3.4s. 

These speakers crave and NEED (250 or more watts++) high current to sound their best. 
But when they get it, they do not disappoint. The internal bracing is overbraced to manage the vibrations that are expected from customers listening to high volumes with high current ... eg, rock and roll, large expansive orchestra's, etc. 
In other words, the Nirvana Bleach and Tom Petty album I listened to last week .... rocked!

Base balls or soft balls or volley balls!!!

If you like your speakers, just buy a big sub.  Sounds like that will do more of what you want.
