What happens when 2/3-way speakers (Say rated 100W) are treated as full range by the amplifier, does the power handling of the speaker come down ? If so by how much does it come down ?
When 2/3-way spkrs are treated as full range by amp,does the pwr handling come down ?

I would treat "power handling" as just something that manufacturers decorate the box with and ignorant sales people prattle about. Not serious or exact in any way.

The range refers to the frequency range and not the amplified power. AV Receivers can decide what frequency range to send to the speaker depending on how you set it up. Usually what is stopped is the low frequency which goes to the LFE channel.

yes it comes down.
if a 2/3 way speaker can handle 30 watts of power when fed a full range signal, when you feed it just 80-20khz it will probably be able to handle more than 100watts. This is with respect to excursion of the drivers. Keep in mind that when you feed it 80-20khz, it will hit its thermal limits much before it hits its excursion limits.

Re: When 2/3-way spkrs are treated as full range by amp,does the pwr handling come do
Thanks for your replies. i had been browsing thru the speaker specifications of Floorstanders precisely PSB Image T6 (Tentatively Next Upgrade). In the online data brochure it was mentioned that the recommended amplifier power is 20- 200 Watts & Programmed for 200 Watts.
From the forum i learnt that it is better to have an amplifier where the power handling is more than the speaker power handling to take advantage. So was wondering how powerful an amplifier must be to drive these speakers.
Marantz receivers when listening to stereo / multichannel source when engaged in source direct mode, treats the speaker as full range. Hence the above question.

That meaningless inexact wattage does not tell you what you need to "drive" the speaker --- it is more akin to the rating of a fuse, in trying to tell you what the speakers will take before failing.
But... it is meaningless and inexact.
There is a little number, usually lost and ignored, because sales and marketing men don't think it sounds as good, called "sensitivity." That is about how easy speakers are to drive.
I'm sorry it isn't as simple as connecting a 200W amp/receiver to 200W speakers, but it just isn't. Unless there is an absurd mismatch, like plugging a low-wattage valve amp into PA speakers, the better amp (or the one you prefer the sound of) will always sound better, and the numbers don't much matter.
Listen to the sound, not the marketing!

Re: When 2/3-way spkrs are treated as full range by amp,does the pwr handling come do
it goes like this. what they say is that amp should be able to provide more than the speaker can handle. the logic is that distortion kills speakers usually. the amp will start distorting at lets say 75% of the volume. if your spkrs are 100w and amp is 200w, you can provide clean 100 watts to the speakers, keeping distortion out of the picture.
All this is fine, but what you need to consider is at what volume you want to play. with good sensitivity speakers, you will go deaf before your speakers blow.
The eff is lets say 90db. this means that 1w of power will give 90db of SPL at 1m distance. each doubling of power will give you 3db more. each doubling of distance will give you 3db less. Now see your distance, your listening volume and calculate your power needs. You should also keep some headroom for those transients. if your needs are 30w, go for 60w amp

Thanks for your replies again. Now i am in a better position to understand the speaker sensitivity & Power handling.

Is that 100W continuous power or of a transient peak? Should be peak as per my limited knowledge.

Regardless of whats mentioned on the box/manual, I can safely say that a 2/3 way speaker is bound to have a 2/3 way passive cross-over, which, like a commission-agent eats up a lot of energy in its efforts to distribute the same to the relevant driver. So, power loss in keeping with the original quetion seems inevitable.
