Generally speaking, In that room 22 watts usually would not be enough with speakers at this level of inefficiency. The thing is, this speaker does not handle a lot of power and in that regard your receiver is a perfect match. So if you plan to be close to the speakers and only using them for background it will work fine.
Speaker Sensitivity AND Power Requirements
Hi all, I'm considering purchasing a pair of heavily discounted Wharfedale Denton Bookshelf speakers from Music Direct. They are 86 sensitivity. This is for my man cave system the center of which is a vintage Yamaha Cr420 receiver which has a 22 watts per channel power rating. Would this be a decent match? 22 watts enough? Thanks in advance.
