It is a fairly large space to fill, on the other hand you are not typically seeking high volume levels. Many amp designers suggest that amplifiers are typically at their most linear when operating at about 20% of their output and further suggest having about 80% headroom above that. Ideally you could try it out with a return option.
100 watts enough?
Hi all. I'm contemplating purchasing a CH Precision A1 and I don't know if it will drive my speakers adequately. I have EgglestonWorks Andra III speakers which are 88db efficient (impedance 8 ohms nominal, 6 ohms minimal). I have a 30x20ft room and I sit about 14ft from the speakers. I live in a condo and have almost nothing between me and my neighbor so I don't ever crank up the volume. I use a VAC Renaissance preamp that I almost never crank past 9 o'clock. The Andra III is a speaker that likes lots of power to open up. So what do you think?

You can also plug in your numbers into this calculator (Amplifier Power Required): https://www.crownaudio.com/en/tools/calculators It would be more accurate if you have an SPL meter but I reckon that most people self-select volume at around 71-74 dB continuous. This is what I call comfortably loud. If you listen at 71 dB, the amp wouldn’t even leave its continuous power range until a peak greater than 24 dB. That level of dynamics would cover large symphonic works, so the amp would be good for basically all music. |
