the_lhc:By how they sound, how else do you judge speakers?
Whilst this does seem the obvious answer, what I should have made clearer is how does cost get factored in??
I know that when passive speakers are tested a range of amps are used. This is not possible for Actives. Therefore are Actives measured against similarly priced Amp/Speaker combos?? Otherwise (just for an example) a passive speaker costing say £900 but paired with a £2000 amp would outperform say a £1125 Active. However, that same speaker partnered with a £225 amp would not perform as well and may not outperform the Active.
Does that make sense??
EDIT - basically all things are not equal when comparing Actives to Passives
Indeed, and are - pound for pound - a worthwhile buy. Several offer a volume control (AVI, Genelec) while others can be partnered with a dedicated pre-amp off a laptop, where onboard pre-amps from whichever music management app can be utilised, or a dedicated hardware pre-amp if needed.
Pricewise, at the £800 mark (where you're clearly in the territory of the budget market popular in this forum and the attendant performance that brings) actives can bring a step-up from that performance.
