Well, I reckon a 30 wpc amp will work out at about 2 to 4 quid per watt,
but
the trouble is you *need* 100+ watts these days (ludicrous) and then I
reckon you are looking at 5 times that sort of money *at least* for
similar
(construction/appearance/appointments) 'assembly line' amps....??

Untrue for subs, Keith. You can buy a 500 watt 'plate' amp with active
crossover and all necessary connections and controls, for less then
three hundred quid. Just the job for getting deep, clean bass down to
20Hz at decent SPLs from an 18" cube. Also one of the last remaining
areas where the home builder can beat the commercial stuff.


The thing with home builders is that just about all of them think they are
beating the commercial stuff or I guess they wouldn't bother??

But it's not all about the money - many DIYers are looking to beat
commercial stuff in terms of ultimate performance/specification and are well
aware they would definitely *not* be beating commercial producers on a cost
basis if their own labour was priced into the equation....!!??

Still true in absolute terms. DIY satisfaction has a lot of clout, but
in the real world, home-built full-range speakers can in no way
compete with good commercial equivalents. All else is wishful
thinking.
