Unknown Polk Bookshelf Speaker

kjsnfl

I found a great deal on a used set of bookshelf speakers, but the stickers were missing. I did a shootout with my Rti4's, Monitor 40's, and Tsx220b speakers and preferred the new speakers. They have 5 1/4 woofers 1 inch tweeters with dynamic balance on them, 2 small front ports, and the rear power port. Anyone know what model I have? I'm also wondering it there is a tower from this series.

RT15i, I think.

Mdaudioguy, thanks for responding. That is what I thought at first. The rt15i has blue woofers. The ones I picked up have black woofers.

I'm really interested to figure this out because these speakers sound really good compared to my other Polk speakers.

This auction says they are rt15i as well. But the stickers are missing on them like mine. 😆

I believe there was a standard rt15 as well

Yes, Polk often introduced a model, say RT15, and then a few years later, would come out with an improved version RT15i. Maybe blue woofers are better!

Blue woofer are always better. Much better than yellow anyway.

Thanks guys! That's it, Rt15.

Now I'm curious if the rt15i is brighter than the Rt15. Seems like a tactic used to "update"Maybe a speaker model. the rt35 with 6.5 inch woofers would be nice as well.

For a 10 dollar thrift shop speaker, I was blown away. I like the balanced sound better than the rti4 which has been my go to for a while. The rt15i has better/tighter bass compared to the tsx220b as well.

I'm not sure about with the Rt15i because it does not seem to have the tri-laminate tweeter which people really seem to enjoy on the larger RTxxi speakers.

The black silk dome tweeters are fine, fairly detailed and not too bright, but don't have as much as or extension as the tri-lam dome tweets.

Msg, thanks for the link.

I have never heard the tri lam tweeter which appear to be silver . I think I want to try them out at some point. How do they compare to Polk's silk dome tweeters?

All the reviews I've read say they don't seem too bright or fatiguing.

I have experienced terrible ear fatigue with Energy aluminum tweeters. That's what always brings me back to Polk silk dome tweeters. I have never had an issue with Polk's.

I’m confident that front baffle helps the SQ
