Hummmm interesting... i never checked this kind of product. CyberData has calculator only for the 8W model, but... every speaker they sell is 8w and the calculator say 69 speakers. You can attach 2 speakers to one amplifier in parallel (they say this also), this is the maximum as the amplifier cannot reach 32W (4 speakers), but you can try to use 4 speakers (2 in parallel + 2 in parallel) with a little less than maximum 8w on each speaker. I think a reasonable number of speakers may be less than half, but you must check wath is in the area, also remember if this is a warehouse to place the speakers where a person can be, not goods. :-) For a so big installation think to use a voip interface and professional product with low voltage line speakers, i think is less expensive. Bye.
