A 10.2 Power?

cogitech · 12th January 2013, 03:59 AM

35 watts nom. 70 Max?

Really? I expected much lower considering the rated power of EL70...

power is something that is really hard to rate. at lower frequencies, a few watts is all it takes to drive the woofer into its 8.5mm of excursion.

power handling seems about similar to other 5.5" woofers.

How much diaphram displacement are you going to get with say...an 84Db sensitivity???? By thirty-two watts we have a mere 96Db & we've hit the rating?

To the point where they arealmost meaningless -- at least for comparing.

What does it matter as long as it's clean power? Just listen to the music and don't listen to loud music.

Why the negativity?

Based on my knowledge of other MA drivers, I just expected the A 10.2 to be rated at maybe 25 or 30 watts max.

I am pleasantly surprised to see that they are rated higher, and I am quite aware already that the ratings are not absolutes.

I certainly don't have any intention of treating them like a 70 watt speaker. I was basically just looking for confirmation that the spec sheet has no error on it.

The issue is, the wattage rating depends so heavily on how we decide to measure. The 10.2 can take 1000W transients. Or, only a few watts with low frequency sine waves. The tweeters with voice coils that melt at 5W are actually rated at 250W "musical" power. The ratings are too variable. That's why speaker power ratings are rarely talked about in DIY.

OK. I understand.

Would it be accurate to assume that Mark rates the power of his drivers consistently, by the same methods/parameters? If so, would it be conceivable to compare, in general terms, the power handling of one MA driver to another based on Mark's power rating?

To be specific, would it be reasonable to expect 1x Alpair 10.2 to "handle" basically as much power as 2x EL70, all else being equal?

Yeah, seems reasonable to assume that.
