Advise for new speakers for my basement exercise room

Hello,
I am going to advise you to buy revel. The M126 is really great. Also because of the waveguide on the tweeter it controls the sound and reflections very well without room treatment. At the shows people ask where the subwoofer is in the room? Very good sound. They are $4400 per pair. The revel stands are $550. All revels will work including the outdoor models if you want to hang them on the wall. If you live near the Chicagoland area this store will let you demo them in your exercise room so you can hear what I am talking about. https://holmaudio.com/
I hope this helps and you can demo them.

Try this.....

 cut an old tshirt in 1-2” squares, tape 1 layer over the tweeter, and give a listen, if not to your liking, put a 2nd layer over the tweeter/horn.  And come back with ur thoughts!

 A very easy fix for bright speakers in a basement with no caret, or high absorbing furniture. 
   Before you make a huge move, give a try, 
did this on my BIC dv-84 towers, treble was very over powering with hardwood floors, and minimal furniture to soak up the treble.

  Please try this,  cut small squares, tape over tweeter, and listen, then try a 2nd layer, or maybe. 3rd,....... 
I did it, and it was a fix of a lifetime! Worked wonders!

My basement speakers are older BIC V-830’s
  absolutely great speakers!

 Bass, mids, and detailed yet non fatuiging treble. 

My workout room speakers are KLH Model 6’s I bought off Craigslist for $75. They sound wonderful paired with my Fisher 800C tube receiver. However as others have said, you need to treat the room to tame it down and stop all the reflections before you can judge.
