Help me ID small RTA speaker

[Emanon13]

Hey. Newbie here. Love my RTA 8TLs. Just changed 50w Yamaha receiver (inexpensive early 90s w Yamaha sources) for 35w NAD integrated amp (mid-90s w NAD sources). No hookup yet. Will I hear differences? I'll be getter better interconnects. Reasonable suggestions? Sound seemed "muddier" over the years. Each old component had issues.

Anyway, real question: What bookshelves do I have? See photos in later posting. Purchased with RTA 8TLs in early 90s at United Audio. Look like same woofer/tweeter but 2-way bookshelves. About 14"h x 10"w x 8"d. Sound great, maybe "cleaner" than 8TLs (no bottom, oc). Sticker ID gone. Tried to ID but can't. Thanks for helping.

Without pictures of the speakers, I'm clueless. As far as the difference of sound between the NAD and the Yamaha receiver, your ears will have to tell you that. I would just hook it up and compare. The NAD integrated is a very musical and underrated amplifier that should sound pretty good and different than the Yamaha. But, again, your ears have to decide that.

Welcome to the forum....

I think that they are monitor 4's IIRC

Thanks, George. Found same (different finish) on ebay to confirm. Polk Audio Studio Monitor 4. What's the "IIRC"? Also... Why doesn't Polk (and many others) keep listings and descriptions of previous products? I can't find it here. Anyway, hard to believe you can get them for $50-60. 25% rule...?
