My speakers are magneto-planar and so present a fairly resistive 5 ohm load but they are very inefficient so require a lot of power. Thankfully the mono-blocks that I use to drive them will deliver lots and lots of power into a loads as low as 0.6 ohms. And in order to minimize the system impedance so that I can make the most of the very low damping factor of my amps I run a short 1m length of old Supra 10mm2 cable, it keeps the bass tight ;-) -- Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://home.swiftdsl.com.au/~distudio//publications/ Pentax user since 1986, PDMLer since 1998 -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
