IME, 8 ohms is usually an easier load for tube amps.
.....I would like opinions on 4 vs 8 ohm as the speakers Im looking at are available either way.....
Another vote for the 8 ohm option. Are your amps OTL BTW? I thought at least some Primaluna amps were and would like the higher impedance...John
Thanks for all the input guys. I appreciate the collective knowledge.Yes my amplifier is transformer coupled. Rusty let me clarify, Im looking at Tekton DI's, they are available in 4 ohm and 8 ohm versions upon request.So Im thinking The route I want to go is 8 ohm speaker and possibly use the 4 ohm tap on the amp incase they dip down lower in impedance from what Ive gathered here.
For a while I ran a 4 ohm speaker off an amp designed for 16 ohm speakers. The amp was running very hot. I purchased a Speltz autoformer which goes between amp and speaker - I set it to present a 16 ohm load to the amp and the amp ran much cooler. Just sayin'.
Okay, I just talked to Tekton. They said "buy the 4 ohm speakers unless you're running an 8 watt SET amplifier." They have to use different woofers on the 8 ohm model, and they feel they are inferior to the woofers they use on the 4 ohm model. With a push/pull amplifier with a 4 ohm tap, buy the 4 ohm model. Minimum impedance is 4 ohms. You'll be fine with your amp(s).
Wish I had kept mine. The least expensive solution is $540 now... http://www.zeroimpedance.com/zeroimpedance_014.htm
This statement are curious, IMO Tekton take a shoot in his foot.I believe they mean say the 4 ohms version delivery more spl, no more sound quality, unless the 4 and 8 ohms woofers are not the same, a 4 ohms speaker reduce the options to use a tube amp.
