Post Subject: Voice coils & horn loading : Electrical restance + Physical loadPosted by jessie.dazzle on: 9/17/2009

I'm picking this up from the "Living Voice Loudspeaker" thread
http://www.goodsoundclub.com/Forums/ShowPost.aspx?PageIndex=2&postID=11765#11765
and placing it here, as further discussion will take us off the original thread :

If you've tried both, and decided to keep the 16R versions, you've answered a question I've had for quite a while; I too use the 16R version, but have always wanted to try a pair of 8Ms with 8 Ohm coils (should have ordered them back when Fane were still in business!), just for the sake of comparison when used in a 115Hz horn.

Sort of on the same subject: I edited the last post I left back in the Living Voice thread; if you've not already done so, it would be interesting if you could comment on my assumption that Vitavox specified a lower R version of their 15" bass drivers in anticipation of the additional load (seen by an amplifier) once the driver is mated to a horn. It seems inevitable that additional physical load would translate into additional R as seen by the amp. Never mind that its likely no commercialized implementation of this driver loaded it to such an extent as to require the lower resistance winding.
