Welcome @stev

 

Here's a link to my discussion about power requirements: https://community.klipsch.com/index.php?/topic/193845-why-flea-power-is-often-enough/&do=findComment&comment=2529684

 

My tube amps that produce approximately 30 - 40 wpc work great with my RF-7II for music that has the most demanding dynamic range (i.e., large-scale classical), in an average size listening room.  With properly implemented subwoofers, I can achieve near live concert hall dynamic range, and frequency range, with 30 wpc tube amps driving my RF-7II.   

 

For big-band music or folk music, my 8wpc single-ended pentode amp sounds great.

 

Unless you have a very large listening room, and/or you're hell-bent on damaging your hearing (and possibly frying your speakers),  I suggest that you reconsider the need for bi-amping, and the need for 500wpc.   With high sensitivity speakers like the RF-7III, if your goal is to faithfully reproduce the sound of natural instruments (e.g., symphony orchestra), IME/O synergy between the amps and speakers is MUCH more important than using an amp that has an extremely high-power rating.   

 

If you want to increase the acoustic output of RF-7III, I suggest that you consider adding a subwoofer with a crossover before the main amp.   (My Oppo UDP-205 universal player provides the bass management function, meaning that the power-hungry bass is off-loaded from the main amp and speakers.)  With that said, you can achieve great sound from RF-7III without a subwoofer.  

 

See my post linked above for more details.   If you want to read more discussion on this topic, I suggest that you google something like:

Thanks Robert 👍

As long as the amp is not clipping at your listening levels, you have enough power.

 

But if you must "match the RF7III floor standing speakers to its maximum level" then according to the specs, 250W is what you need.

 

At 100dB efficiency, you'll hardly need half that much, let alone bi-amping the speakers.

Thanks.

What would be the best amplifier in  Rms watts to match the RF7III floor standing speakers to its maximum level. i was thinking of either seperating and bi amping each speaker and giving the highs 225 watts rms and low bass 225 watts rms or having a 500 watt rms amplifier running them both. Is there a better way to get the most out off them?...
