Perfect from the Whisper to the Shout

Our Best Sound Balance 

Enjoy better-balanced sound output from the CAS-1, courtesy the brass spikes elevating the speakers and dampening higher frequencies and fixing woofer-tweeter route discrepancies. Plus, enjoy better balance even with headphones on, courtesy their own dedicated amp. With their own customized bass reflex ports, each CAS-1 speaker creates deeper, richer, and more powerful extended bass. Enjoy your favorite tracks’ beats’ drivers with superior clarity and depth. 

Easily Position (and Re-position) 

Easily position the CAS-1’s speakers for the best listening experience. Place to get the most out of its near-field listening, and use the brass spikes to adjust the speaker angles. Plus, use the included speaker bases to produce more stable acoustics on any surface. It’s the perfect fully-portable sound system.
