Almost everyone sets their fronts to small when paired with a decent sub. Also 80Hz is the universally recommended crossover, but you can swing between 60-100hz and experiment; good luck

Very true. Depending on the phase roll-off characteristics of your speakers in conjunction with the subwoofer, different crossovers may result in better output performance. Remember, the crossover is not a brick wall and some nulls and peaks may develop at the crossover points depending on the output of your speakers and subs.

Otherwise the sound is muffled and makes me question there quality.

I have them on a decent volume -57 db . I also lower the higher frequency to -10 db 8khz and 16 khz. U will obviously tune them to your hears but don't worry about the post saying these needs so much power ...Just worry about there mids wich as to be addressed by eq.Other than that they are a great set of speakers.
That's an interesting observation, but one I can't agree with. My RTI8's were exactly like I had read about. Great mid's right out of the box and that famous Polk RTI sizzle (or sparkle) at the top end. The top end can be corrected with a little eq to begin with but mellow out after break-in, but the mids (at least mine) have been kick ass from the beginning without any assistance. Love my 8's.

The Rti6's and Rti8's are both great speakers. I've used Rti6's (later upgraded to RtiA3's for cosmetic reasons) as mains for TV viewing and casual music, with the A3/Rti6's running full range and the Csi3 center and Rti4 surrounds set to small and crossed at 80Hz to a small, articulate 8" sub. Sounds great for what we use them for. Also used Rti8's as surrounds for HT duty, later moved them to the bedroom for night music until later replaced by Lsi9's.

The Rti6's are sometimes criticized as having a dip in their midrange response and therefore favoring male voices. That never bothered me. If so, the 8's should be an improvement as I understand it the two 6" drivers are split between upper midrange and mid bass duty. BTW that 15" HSU sub sure looks awesome... sure wish I had one.

For anyone chiming in on this as far as xover freq vs full range, all I can say is try everything and go with what sounds best to you. It may well turn out that one setting works better for music vs HT, and for HT vs TV etc. That's how I happened to end up with so much equipment.

I've tried: 80, 70, 60, 50 and 40 and have always settled on 40hz. With extra power going to the center and the other speakers, my taste has fallen in the 40 range for the center and mains.

My friends can't tell the difference when a CD is playing or when the 320kbps mp3 is playing.

For Rap, Electronic and any music with a deep and heavy bass line requires a sub.
Otherwise here is my breakdown:

Country: 10/10 (clean and crisp, very detailed)
Classic Rock: 9/10
Electronic (with sub): 8/10 (ability to bring out all the details and keep up with the beat)
Pop: 8/10 (requires a sub)
Acoustic: 10/10 (each twang can be heard and felt)
Orchestra: 9/10 (clean and detailed)
Rock: 7/10 (instruments don't have enough room to stand out. Guitars don't sound crunchy enough for my tastes. Sound stage not as big as other genres)
Metal: 8/10 (Has a nice mid bass kick to it and the thrashing of drums really have weight)
Male Vocals: 9/10
Female Vocals: 10/10

All in all they're on par with bookshelves up to the $2000 range. I love them, but bands like Guns N' Roses, Pearl Jam could sound better Maybe I'm too used to rocking out on tower speakers.

This was an excellent break down. Much appreciated as I am mainly a listener of; country, "classic" rock, classical, some blues and the order preference changes regularly.

Hi. I have a Polk 7.2 system. Rti a7 and csi a6 center. Two psw505's.

I'm thinking to upgrade my towers to rti a9's.

I mostly watch movies and have crossovers set at 80.


Do I need a separate amp for rti a9's to perform well?

My Yamaha is 145 watts per channel.


P.s, this upgrade would only cost me $200. have a deal on some and would sell mine.
