how to know wattage of speaker

Power rating can not really be measured AFAIK and is not terribly important anyway for domestic use. I have no qualms hooking up a small 15W fullrange to a 1kW amp; the speaker will 'let you know' if it starts to feel unhappy with its drive level, just be gentle when cranking it up.

OTOH, do you have a model number or pictures? Is this a vintage Philips? I kind of like these, having owned a couple of pairs myself.
 
A warm welcome to the forum with this, your first post!

Like IG81 has said, please tell us the model number and/or a attach a photograph of your Philips speakers, as we may then be able to identify their power handling capability.
 
Dear IG81
Thanks for the reply. I have acquired 30+30w amplifier. Class D. Thought of connecting.
It's grate, you have 1 kw amplifier.
Thanks to all for responding.
If I get information about this speakers it will be great.

Ouch, these are trashed something bad!

For the record, I do not have a 1kW amp, I merely mentioned an arbitrarily large number to make my point. 🙂 My present amps range from 2.5W to 100W.

I used to own the very similar Philips AD7060/M8, quite good, though I never did design an enclosure to truly make it shine, as I had other vintage drivers at the same time, in which I had more interest. I ended up selling them to another forum member. Mine came out of Norelco enclosures.
