[QUOTE="Brad Weber, post: 32767, member: 114"] Re: 70v System vs traditional... Just to clarify in light of JRs comments, I was not recommending a series-parallel approach as a solution, and if you do use that approach I strongly agree about documenting it, but rather addressing the earlier comment that four speakers would equate to a 2 Ohm load as that all depends on the wiring scheme used. The other potential element in that is the volume control as that could come in a number of different 'flavors', especially with some consumer oriented products. Another benefit of 70V systems in some applications is that it can be fairly simple to adjust the relative level of individual speakers without requiring accessible volume controls at the individual speakers via the proper selection of of transformers and the associated tap values.
