The Volti Audio Rivals w/ their 15” pro audio sourced woofers, while maybe only flat to 35hz, can play as loud as you want & sound great doing so in just about any size room. I have listened to Jethro Tull’s Aqualung on many good systems & thought I knew it well. Then through the Rivals w/ a good tube amp, I heard the true impact of the bass guitar & drums like never before. It was up very loud & I was both scared & cracking up at the same time. That said, Martin Barre’s guitar solo on the cut was also outstanding w/ power & body that few speakers can do at least for long.
If you want the volume & dynamics of the old JBL’s, Altecs, Klipsch, Cerwin Vegas etc & the nuanced detail & imaging of good modern speakers, check them out. Imo, They’re the closet thing to live music I’ve heard at anything near a reasonable price. Their “smaller” model, the Razz, comes pretty close for less than half the $. ( about $6K vs about $15K). Both are so much fun!!
