You don't mention whether budget is a concern, but I'm going to assume that "money is no object" does NOT apply.

Of those you mention (and bear in mind that there are a host of other suitable options available to you), I would recommend that you go with the 80F/X-RT, with their dual 3/4-inch aimable tweeters and 8-inch woofer. You can currently buy them at Polk Audio's eBay store for $216 a pair. They are listed as refurbished, but my extensive experience is that you will not see any difference between the new and refurb'ed speakers they sell other than that the refurbs carry a 2-yr warranty vs. 5 years for new.

FWIW, I originally purchased my first pair of 80F/X-RT for use as surrounds and chose them over the RC80i for their quality, versatility, and with an eye to upgrading my mains at some point from the Monitor series to the RTi series (which I have since accomplished). As surrounds they are fabulous; as heights they will see much more limited, less demanding service; but there's no substitute for quality and they're still a great deal at the discounted price of around $100 each.

I did make backer-boxes for my four in-ceiling speakers and would recommend that you do as well if feasible. I wanted to protect the speakers from heat and debris in the attic as well as to enhance their acoustical properties. I made my backer-boxes out of cheap rigid foam insulation boards that I had on hand and foil duct tape. Here are some pictures:

Thank you for the detailed reply. In particular the home made backer boxes with common materials. The Polk eBay store is exactly where I was looking at the 80 f/x-rt. it is s great buy. I decided for the 700-LS. I may upgrade my fronts to the LSI Polk's at some point and this would match those. Tip ended up getting the 700-LS for $100 each which I just couldn't pass up. Here is a link to the LS-700. http://www.polkaudio.com/700ls/d/1065C2880


Thanks again.

Help please Polk LSiM series issue

Hi folks....really need some help with this...I have the LSiM series speakers 705s,706, 703s...I am running a Denon 4100 as a pre amp into an Emotiva UPA-7 125 wpc 7 channel amp...I am streaming FLAC via a Sony BDP 6200 from a NAS...

When listening to 2 channel, I seem to be getting a certain underlying resonance with high pitched female vocals that follows the frequency of the vocal. 3 of my 5 speakers had the tweeters replaced as there was an obvious vibration coming from the tweeters when listening to certain material. I tested against that same material, after replacing the tweeters and it is not vibrating any more...

To test whether this was a room acoustics issue, I put the 706 mother center in the middle of the room and treated it as a left channel. Same resonance occurred during high pitch sound with certain material. This speaker is brand new and did not have the tweeter replaced.

Looking for advice folks...is this a speaker issue, room issue, equipment issue or source issue?

Thanks folks, really need your help as these speakers are not inexpensive...

That sounds pretty much how my tweeter sounded when it started to go bad in my 705.

Uggggg, I was afraid you were going to say that...did you replace the tweeter? Did it fix the issue? I have replaced both tweeters in the 705s...

Hi everyone, i currently have a 7.1 setup (FR: Monitor 75T C: CS2 SR&SBR: TS110). i would like to upgrade to a 7.1.4 setup. Please what in-ceiling speakers would you recommend i get?

I also wanted to ask if there's a noticeable upgrade (night and day) in sound quality upgrading my Fronts to the RTIA7. Unfortunately i dont live in a country where i can demo the speakers.

Thanks for your advice and insights.

Thanks RobLee, if i do upgrade the Fronts to the RTIA7, would the timbre difference be off much from my current surrounds (TSX110) or do i have to change those also?

I would also appreciate any recommendations for in-ceiling speakers

Thanks again.

monitor 75 -> RITA 9
monitor 65 -> RTIA 7
just so that you know there will be some difference in the base response if you move from a 75 to a RTIA 7 without using a sub. You'll want to update the center when you have the chance.

Call Polk Audio and ask them to send you a new tweeter. My 706 had the same problem and after replace the tweeter with a new one the problem was solved. I also had same problem with one of my 703s tweeter but I took the tweeter out, disassemble it, assemble it back and the problem is gone.

Thanks my 705s both have new tweeters from Polk but still getting resonance. Are you able to tell me what was involved with disassembling the tweeter. Are you suggesting you took the casing off the actual tweeter and looked at the guts of it...was there anything obviously wrong?

What do you mean by resonance? My issue was more like distortion or RF sound coming out of the tweeter itself at certain frequencies. Resonance is more related to the interaction between the tweeter assembling (case) and the speaker cabinet. I never had resonance issues with my LSiM speakers.

Thanks, it's hard to describe...during certain high pitch vocals, if I put my ear up to the tweeter, I can hear a resonance or vibration from the tweeter that follows the pitch of the vocal...I hear it in my seating position so to verify I put my ear up to the tweeter and that is where it is coming from...not sure if I am calling it resonance and u r calling it distortion...RF sound might describe it though...does Polk have an issue with their tweeters in the LSiM series? Also can you help me better understand the disassembly of the tweeter? Thanks again...

Take the three screws out, pull out the tweeter coil just a little bit (be careful with the coil wires) and put everything back.

Your surrounds should be fine for a while. It is not nearly as important that the surrounds match as do the front three. As Pretzelfisch mentioned, you will definitely want the center to match your Rti mains. You can usually find Csi5's online for under $200.

In my case, I upgraded the center first, from a CS2 to a CS20, and finally to a Csi5. The difference was literally "night and day". My Monitor 70's sounded so muffled compared to the Csi5. From there it was a natural progression up to RtiA7's and eventually A9's, then I replaced the Csi5 with a CsiA6 center just so the cabinets would match.

Wholly crap, wow, thanks...what do u think the actual issue is?

Also, if I pull out the tweeter coil just a little bit, will the 3 screws go back in correctly...?

Thanks that is my plan; upgrade each section one after the other (fronts, center and then surrounds). i have been reading a lot of reviews here and the LSIM series (705) has really piqued my interest. Its way beyond my budget for speakers. I was thinking since i have to ship the speakers in to my country why not just get it now than get the A7 and have buyers remorse. My only fear is that it might be overkill for my needs, my current setup is 95% movies and 5% music.

Is the A7 better/ more suited for movies than the 705?

Thanks again.

Thanks again. If you've heard the LSIM 705 i would really appreciate your thoughts comparing it to the A7 for Home theatre use.

Old vs New

Hi All
I have lsi9 mains with a lsi center, has anyone compared them with some of the cheaper options from Hsu (HB/ H-1), Ascends (CMT 340 & CBM-170), EMP-R6Bi or the SVS Prime bookshelf and center.
Would any of theses brands be a up-grade from the Polks? My Polks are 10 years old.

When I pull the tweeter coil out just a bit and put the 3 screws back in, the coil goes back to close to its initial position and sounds the same...what am I doing wrong?

I have both the LSIM is better, It's had to say if for the money it's better enough to buy them.

I have never heard any of the LsiM line, though I own a pair of Lis9's which I use in the bedroom for music only. I tried them in our living room for HT and was somewhat disappointed. Furthermore they sounded terrible for TV viewing. They are great speakers for music and I'm sure they are decent for HT use, but at their price point I could not justify replacing a room full of Rti's with Lsi's.

I once cried because I had no Atmos, until I met a man who had no stereo

Thanks a lot for that. It really cleared things up.

I used the A7's for a while until I found the A9's on sale at 50% off. Then I had to buy an external amp because for the A9's to sound great they really do need more power than an AVR can deliver. So there is a price to be paid for the A9's and the A7's are essentially the best deal for most people who cannot justify paying that premium.

RC80i versus 70RT?

Hey guys, I'm in the middle of a kitchen remodel and would like to install a pair of ceiling speakers in the kitchen, plus an additional pair in the adjacent dining room and another pair in the adjacent family room. I originally thought I would just with the RC80i based on the positive reviews on Amazon and value pricing, but am now considering the 70RT because I prefer the visual appearance of the 70RT. Aside from the appearance, however, I was wondering if people think there is a noticeable difference in sound quality between the two speakers, considering the 70RT is double the price. Thanks for your help!
