Hi I use various loudspeakers in the Uk for conducting onsite sound insulation testing of partitions. \nIm building a battery power loudspeaker that have 6 individual loudspeakers arranged in a way to give an omni directional sound field (hemisherical). Ive powered it up using a big amp i have in the office and all seems good. \n\nMoving onto my question. See diagram attached. I am arranging the speaker wiring in a way that give the overall spec of 2.67ohm and a total power 168W. The class d amp i want to use is rated and 200w @ 3ohms. Is being 0.37 ohm low too much?\n\nWhen this speaker will be used it will be set at a certain volume and left (no cranking). It is only used for short burst up to a minute long playing broad band pink noise. Is this okay or should i rearrange the wiring to give 6ohm which is possible. Im concerned this will limit the output too much.
