Hi! I want to upgrade my old gigging amp with external cabinet. Can you advise me what would be optimal external cabinet specs for ibanez soundwave 100w bass amp? In the manual it says that: 1. In addition to the SW100’s internal speaker, you can connect an extension speaker that has an impedance of 8 ohms and power-handling input capacity of 100W or greater. 2. OUTPUT POWER:100W @8Ω :145W @4Ω 3. SPEAKER UNIT: POWER JAM 1508B, POWER HANDLING: 300W (600W PEAK), IMPEDANCE :8Ω I am not sure how to understand these two things: a) "100w" or greater - by how much greater it would be OK for amp like this? What will happen if i add cabinet able to handle 400w @ 8 ohms and more? b) POWER HANDLING :300W (600W PEAK) - how this goes together with 100W @8Ω :145W @4Ω? Wish you all great weekend out there gigging!
