Unlike the Tang Bands ( on the right ) the Beta/H-frames are very affordable and cost under $300 to build. Compared to the more refined Tang Bands, the Betas have that pop factor and will rock out on more types of music. The Betas can handle complex swings in dynamics common in full scale classical movements but may lack some of the hyper detail of the TBs. I like them so much I decided to retired the TBs for awhile. If you want a big sounding OB that will play loud as hell yet has lush mids and tight bass with sparkling highs this should be your next build.
