I put 4 of the infinity's in my f350 and it sounds incredible , I don't think the Polk speakers can hang with the infinity speakers. Mine are rock solid

I've always admired the treble and highs on polk audios. That's just my opinion though. Infinity is a good brand too.

Definitely a better speaker than the Infinity and Klipsch. I would not but Klipsch because their speakers tend to miss out on mid-range. The Polks will work better with higher end receivers and will shine with separate amplifiers.

I looked up the tuner and i can say it would be perfect match my friend, because the tuner is the right amount of watts 80 watts just get a 12 inch woofer at least ok because the speakers do sound good but really would sound better with a bigger sub, please you have to make sure you separate the sound good, i sold them ASAP because my tuner was at 120 watts per channel way too many, they feel cheap but much better them a lot of speaker i have owned, if you want a very good sounding speaker take your time and by piece by piece polk you can buy on ebay but go with polk.com and down on the right click on polk ebay and get the refurbished- they are good as new trust me i have the TSI300 & Monitor 50s like new you cant tell- so take your time man trust me with the Onkyo will sound so good it would blow you away, if you have any other Q.A please email me bro?

I do not know the BIC DV 64 speakers, but I do love the PL-89's. The overall sound is great, but I do still use a sub woofer because the bass is good but not great.

More power is better. I installed these in a Lincoln Continental. I used a four channel 125 watt @ 2 ohms amplifier in my set up. This was more than enough power for these speakers. Infinity is known for their treble frequency reproduction. These are quality speakers at a reasonable price. If your just replacing your factory speakers.. You should consider at least installing an aftermarket head unit. You can really push these speakers. They sound best with adequate power. Under powering ANY speaker will give you subpar performance.. Installing an amp is a simple concept. Tuning your amp and speakers is more complex.

I really like the sound of these speakers, but I am afraid I have not heard the Polk speakers you are asking about. Sorry I could not be more helpful.

Try CNET reviews and here is a link that provides some of the specs. http://speakerreviews.info/polk-audio-rm85-5-channel-home-theater-system-reviews/ These are really good sounding speakers.

i think it would be a great match for the infinity's. I have mine hooked up to a set of polk db6501's and they get pushed great with everything set far below the max punch eq just below1/2 and gains on front and rear at about 5. this give's me more then enough power to have clean load listening over my jl 12 w6. and your infinity's should handle the mid's a lot better then my polk db6501. my amp also came rated at 522w rms so @4ohms 97w rms @2ohms 130w rms and 261 x 2 @4ohms. hope this helps

I've never used Polk. These speakers don't have a lot of bass. It also matters were there installed.

Tough question...These are very solid and seemingly well built speakers. On the other hand $6 each seems cheap. I didn't get the warranty. I believe in the quality Infinity. By the way. They sound great.

Hi Jim, I really can't speak to the specific sound differences, I can say though that the Polk has a nice, tight punchy bass and I have been very happy with it's performance

Get a yamaha or a denon. These are comparitvely priced and will not disappoint you. As far a speakers go with polk. Yes I know you friends are probably telling you bose - don't listen. Actually do listen, if the can hear side by side polk and bose played through a yamaha, denon or harmon karden you will wonder why boses were ever invented

The Infinity Reference coaxials are voiced bright, but work well if you are off-axis (tweeters not pointing at you). These Polk db651 coaxials are more neutral and transparent, but sound better on-axis or slightly off.

Based on Polk's website I would say no. Take a look here: http://www.polkaudio.com/products/db521

Well infinity subwoofers are good with any amp. They are really great subs.

The P143's are a good value and very decent speakers. The Infinity P153 speakers are just slightly higher priced, but a little larger and with better bass. If you have a little more room, I'd go with the P153 - but the P143's are good and are a very definite upgrade over TV speakers.
