Key specs that matter

Input impedance is 5,000 ohms balanced or 7,500 ohms single-ended, matching the 7B Cubed. Output power is a substantial 600W into 8 ohms, rising to a staggering 900W into 4 ohms, also matching. Frequency response extends down to 1Hz and up to a wide 100,000Hz within plus-or-minus 3dB, also matching. Signal-to-noise ratio is an exceptional 120dB via XLR or 118dB via RCA - marginally higher than the 7B Cubed. At 432 x 423 x 206mm and 41kg, the 14B Cubed carries considerably more mass than a single 7B Cubed monoblock, reflecting its dual-channel internal architecture within one chassis.

Sound and use context

Expect extraordinary dynamic authority reflecting the staggering 900W-into-4-ohms-per-channel output, consistent with Bryston's broader precision-engineered philosophy, in a convenient stereo format.
