Unity Audio will be shipping the new Boulder MKII at the end of June. The three-way active monitor will retain all the great attributes of the original MKI, for example the same Baltic birch sealed plywood cabinet, albeit larger to accommodate the two new 8in SEAS woofers, the original ELAC coaxial 5in midrange with 50kHz folded ribbon tweeter, and the same custom E.A.R Class A/B amplifiers and crossover.
The results of the four 8in woofers over the previous four 6.5in woofers is an increase of 4dB in SPL figures and more low frequency extension with the -3Db point in the low 30Hz region and -3dB at 36kHz.
The Boulder MKII has the same fast tight transients with the bass being reproduced as before but now delivered with detailed sub frequencies too as the 8in woofers move a lot more air. The new SEAS 8in woofers also produce more clarity and detail in the lower mids, up to the crossover point for the 5in mid driver. The folded ribbon tweeter is now measuring -3dB at 36kHz.
