In Reply to: Is a 2A3 amp considered the ideal match for Klipsch Cornwall speakers? posted by mshan on February 6, 2007 at 08:31:16:
Hello,When considering what a SET amp can drive, keep in mind the law of 8, which is:
- at LEAST 8 ohms impedance, without any dips
- maximum 8 inches driver sizeIf you go below 8 ohms, dynamics and bass will seriously suffer, and when you go above 8 inches, speed and impact will be lost. BTW, 2A3, and lower power amps really, really need single driver speakers, and you will need a long time to figure out the right speaker cable combination. The lower power, the more the weaknesses of your chain will be shown, as the amp does not compensate for the lack in the front end.
I do not say that higher power amps do not sound good, or that multi driver speakers have to be tossed, or burn your 8in + drivers. Not at all. These can sound real good, esp with rock or jazz. However, if you are into reproducing acoustic instruments with tone, and you want to delight in music, then low power SET - rule of 8 to go. If you want to delight in the sonics, and music is secondary as far as it sounds good, then forget single drivers and low power sets.
For me the trick was learning hearing phase. Once you get to ear correct phase, it is very hard to go back to multi driver speakers, even ones that are so-called phase aligned, as you hear right away the component (incorrect phase) which makes the sound not natural, even though the speakers might measure flat from 20Hz to 28kHz. However, not everyone wants natural sound. Most folks want something that sounds different from acoustic instruments. Most want an upgrade - even higher detail, dynamics, whatever steroid or plastic surgery substitute to compensate for lack of hearing or taste. Depends on what you want. Every one of us is different, and you have to go on, and try out different things to find what is the sound you are after. This chase keeps these forum alive, an us happy.
Long live DIY!
