    Default monitor 5B compatibility question

    So I'm just starting out in the vintage audio world. My first purchase was a Pioneer sx-626 which is in great shape and everyone says it is a great receiver just low powered at 20wpc @8 ohms. I then came across some 5Bs that had one blown tweeter, so I decided to order up the RDO's to replace them after reading a lot of great reviews. Now I'm hearing that I have to be careful running those speakers with that receiver for fear of clipping them. What are your guys thoughts on this? I'm hoping this isn't true as I just dropped $100 on tweeters thinking these would pair nicely with the 626.

    Sorry for the long post, just a little confused now.
    Thanks

    Welcome to the forum!
    Something doesn't add up: I see specs that call out both 110 Watts/channel and 20 Watts/channel and they can't both be true (even if we're talking about into different impedance loads).
    If it's the former, you should be ok; if it's the latter, I don't see how you could drive any "hi-fi" speaker (clipping would be the least of your problems). If it came with some documentation or you can get a definitive reading on the power, then post back.

    That's my issue, it says 20 wpc for 8 ohms and up to 110wpc for 4 ohms, if anyone that has owned an old pioneer please chime in as I'm still not sure but am really needing to know.

    Welcome to Club Polk. The specs from the owners manual are rather interesting:

    The 5Bs are 6 ohm nominal, and rated 20-125 watts per channel. I think you'll be fine.
    BTW, I have the owners and service manuals (PDF) if you need them

    It'll be fine for most listening levels.
    Unless you always listen at really high volume, it'll work great.
    Also, old pioneers sound more than what the watts suggest.
    I have SX-580 and has enough power.
