Does anyone who owns these know what the frequency response is? It seems they forgot to put it in the product description. Thanks!

Jayce gave you the frequency swipe. The fs is on the speakers is 58.4. I have them with 45WRMS on the back deck of my car, and they do fill in the bass wonderfully. Not sure how they'll perform without an amp.The treble attenuator is very handy as well, it handles highs terribly well!These are at level with some kenwood excelon I had some years back... if not better (due to treble response)If you buy them, you will not be disappointed!

what is the RMS wattage output?

There is no output. These are speakers, not an amp. Per JBL specs, they'll handle100w continuous, 300w peak.

Is this a pair of speakers or a single speaker?

Its a pair of speakers. 2 pieces.

What's that little button in the middle of the speaker and does it mean anything?

It is to adjust the sound of the tweeter but i cant tell any diffrence .
