These comments are incredibly helpful: I’ll pull out the sound meter to check the minimum maximum with the current setup that I would want to commit to, and back calculate from there. I recognize the ambiguity of “83 to 86” but that’s the best I can get from the website on the W5s. Interestingly, in hunting around, the W8 seems to come even lower at around 81.5 even though the spec sheet says higher, and one reviewer claimed that there was some email exchange with the company reportedly suggesting “1,000 W into 4 ohms” was appropriate power for the W8s. That, my friends, is for MC’s reading pleasure...
