power handling

Long time lurker, first time poster. In an interview at Erin's Audio Corner, Purifi co-founder Lars Risbo mentioned that a driver playing a narrow passband can generally produce higher SPL than the same driver playing a wider part of the spectrum. If this is true, there must be some...

I don't entirely know where I got the notion, possibly mental leakage from hard powering off PC's but are there any reasons not to power on / off your audio equipment. With recent interest in grounding, and the depth of electrical knowledge on here I thought perhaps someone would have some...

When a company says that their 4 or 6 ohm loudspeaker or driver handles say 100W, is that 100W at the nominal impedance, or 8ohm? To further illustrate, if Seas sells a tweeter that’s 4ohm and handles 50W, is that 50W into 4ohm (only 25W into 8ohm) or is that 50W into 8ohm (100W into 4ohm)...
