Infinity RS3b sensitivity?

[Al Nacho]

I have a set of these, refoamed them twice and love them. I cannot find sensitivity specs anywhere on the web. Anyone know what the sensitivity is?
I am driving them with a tube amp and have had it suggested that I am underpowered. I supplement them with a subwoofer set to come in at about 60hz.
Thanks in advance for the comments.

If I had to GUESS, around 86-88Db sensitivity.
Those are from the series and time period where sensitivity wasn't high and good clean plentiful power can make them really sing.

I use a subwoofer with my RS II's. Probably don't need to but I have one so why not use it.

I looked there first thing before replying, I didn't see any spec for efficiency/sensitivity shown.
It's possible I missed it?

While Klaus' website is a great resource not all the information provided is accurate. Most is though. Blame could be placed on poor record keeping by either Infinity or Harman.
Crossover changes (revisions) seem to be somewhat common for example. Whether by design or product on hand sometimes the actual crossover as built doesn't match the "official schematic".


EDIT---like much of the universe I often spell Harman incorrectly. So I fixed it.

My slightly smaller set of RS4b like a lot of power- if I had to guess I would say around 86 dbz, they take twice as much power (using the meters on my Onkyo M508 or M506RS amps) to get them loud as it does for my Monitor Audio Silver 500s, Silver 100's, and Bronze 2's which are all around 92 dbz. Those RS3b's are fantastic with a big high current amp.
