my amp broke in a year of me getting it and i luckily got it replaced at the store but i think its my loud speakers ohm that caused it to fail.
i been using some old speakers my mum gave me.
on the back of the 2 speakers it does say 8 ohm but when i look in at the circuitry on both separate loud speakers i see a bass, mid woofer, tweeter all in parallel. i know the bass and mid are both 8 ohm because its wrote on the drivers but the tweeter has no markings on it stating its ohm.
i don’t understand how each cabinet could be 8 ohm as it states on the back of them. if the tweeter was 8 ohm then the math is
mid – 8
bass woofer – 8
tweeter – 8
(8 x 8 x 8) / (8 + 8 +8) = 21.3 ohm that cant be right ?
if the tweeter was 2 ohm the hole cabinet would be 7.1 ohm . but tweeters are normally a much higher than 2 ohm. whats going on here have i got it wrong? was it the speakers that broke the amp? :S
amp spec
*Cambridge audio A5 60w per channel 8 ohm
*speaker impedance 6 ohm – 16
loud speakers
60w
No – they’re 8 ohm because the boxes will have a crossover (passive) built into them – they only cover part of the avaliable frequency band (impedance is only slightly like resistance – mostly it’s not – the impedance ratings on your speakers are usually a nominal impedance at 1KHz – the actual impedance varies up and down the frequency spectrum – at low frequency it will be lower, and at high frequency it will be much higher).
