Peter, when I bought my last car, I asked "how fast does it go?" which is the equivalent of "how loud does it go, without distortion and maintaining reasonable headroom?"
138mph... great lots of headroom, effortless 70/80.
My other question was, "what's the consumption - (a) if I drive it sensibly... and (b) if I floor it?" "How much petrol will it drink"... being the equivalent of "How much amplifier power to achieve said performance"
(a) mid 40s
(b) mid 20s
Why would I want a 4.4Ltr engine when a 2.2Ltr engine gives me that performance and consumes less fuel?
Which is better - a sub that produces a maximum SPL of 138db at 1w/1m with 400w or one that needs 1,600w to produce the same SPL (given all other measures being even)?
