These cabinets have been designed for players who want an extended bottom end, however, each cabinet has it’s own qualities. The 500W 1528 features two 15” drivers whereas the 1818 has one 500W 18”, tuned to 32Hz and 28Hz respectively; therefore both highly suitable for 5 string players. Sonically the 1528 has an inherent natural ‘boost’ in the 80 to 160Hz range which really brings out the bass in a live mix, whereas the 1818 has a fairly gentle curve all the way down to sub frequencies. Both cabinets are rated at 8Ω therefore we recommend pairing them with the standard 1028H for full range sound and full output from the amplifier.
