Product description
AsciLab's flagship passive bookshelf: a 165 mm Purifi aluminium woofer flanked by two 8-inch Purifi passive radiators, with a 25 mm alumina-ceramic dome in an FEA-designed waveguide with phase plug. A 4th-order 1 kHz crossover and Klippel-NFS tuning yield a linear response, 41 Hz extension and a 102 dB maximum SPL from a sealed-plus-radiator cabinet.
