My speaker journey is the strangest part of my audio history. I started with AE109.to the Jamo 8 to Wilson Benesch Actors to Silverline SR17 to Wharfedale Opus 3, through a whole gamut of Open Baffle speakers to frame based speakers to now a hybrid of frame and bookshelf speakers. For me speakers influence the sound more than anything else in my system. The Hawthorne duets being my longest kept speakers and even they went through a few modifications over the years.
For the last 6 months I have been using the Klipsch RP 500m. These are fun speakers and they produce a good bit low mid/bass clout with a tight extension if you block the ports and perhaps not the last word in refinement.

The tweeter is offset has a wave alignment lens and is made from annealed aluminium.
Mid/bass is provided by a duel 4.5 inch double surround system. Crossover is 85 db which is quite low by my standards. Highs are 22,000 to 67hz. Crossovers are built with the latest premium quality parts, including polypropylene metal-film capacitors and air-core inductors
Out of the box the first thing I noticed is the weight nearly double the weight of my Klipsch. They are black with a white front. I would of preferred all black myself. I initially listen without the subs. The mid/bass punches even more than the Klipsch which works for me. Bass is tight but they do need a subwoofer to get the best out of them. I blend in about 64 db this seems to work well in my room. The bass adds a bit more warmth and depth and is beautifully integrated.
The treble is perhaps the cleanest treble I ever heard, it not brightly lit at all. perhaps not the last word in treble extension but detailed and clean. At the weekends I usually play for a few hours with this between 5 to 6 hours with each session. They have plenty of speed and a tight punch, but also capable of seducing. Going back to the Klipsch they just do not have the same level of refinement and musical coherence. Everything is just so clean that even difficult tracks sound reasonable on them.
