Any Frequency responce curves for polks RTi line of speakers?

sheesh....

I know it is not exactly what you were asking for, but if you want to go just based on specs, I have to recommend the Mackie 824's. This is their frequency response. (see image)±1.5dB from 39Hz on through 22.5kHz, and each unit is within 0.5dB of the rest
A friend of mine has a pair (paid about $1300 for the pair - self powered) and has them hooked up to his computer to master music with. I dont know if it was his computer, the speakers, room, or what - but I didn't like they way they sounded at all (very thin sounding). Then again - he knows what thier frequency response looks like in the advertisement so he knows that the sound is as good as it gets for speakers...... :rolleyes:
I have heard others say they sound phenominal, but the point is that my friend purchased the speakers with a flat response so he wouldn't have to worry about source, room, or other issues. He knows his speakers have a flat frequency response so he doesn't worry about the fact they sound like crap.
To each his own....

Edit - frequency response and more pointless ramblings.....Mains.............Polk LSi15 (Cherry)
Center............Polk LSiC (Crossover upgraded)
Surrounds.......Polk LSi7 (Gloss Black - wood sides removed and crossovers upgraded)
Subwoofers.....SVS 25-31 CS+ and PC+ (both 20hz tune)
Pre\Pro...........NAD T163 (Modded with LM4562 opamps)
Amplifier.........Cinepro 3k6 (6-channel, 500wpc@4ohms) -
You obviously didn't read the above posts where we stated that the frequency graph has absolutely NOTHING TO DO WITH SOUND QUALITY.
It only tells you the relative balance of the volume of the individual frequencies from 20-20 or whatever the range is over. VOLUME DOES NOT CORRELATE TO ACCURACY. So your statement that since those speakers frequencies are all within 1.5 decibals(VOLUME) of each other that they should be the best out there, is uninformed. It has no correlation to how accuratly the frequencies are reproduced.
It does tell you whether or not the bass/midrange/treble will be too loud(subjective) relative to the other frequencies.
Read what triton man put up: From Polk themselves http://forum.ecoustics.com/bbs/messages/34579/131062.html

"While no measurement technique can fully describe the subjective sound of a louds peaker, MLLSA and other frequency response measurements are of great help to Polk engineers in developing better sounding speakers. Only a fool would design a speaker based on measurements alone and only a total fool would design a speaker based solely on subjective listening"
"The measurements save us time and are a great help in pointing us in the right design direction"
"The measurements give us a means of selecting which experimental designs are worth listening to."

JHC!!! Nobody here has a frequency graph for your speakers. You can try asking Polk for one and I wish you good luck in getting it. Now drop it!!!Political Correctness'.........defined
"A doctrine fostered by a delusional, illogical minority and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a t-u-r-d by the clean end."

I only continued this discussion because you all were telling me that graphs mean nothing and that I should ignore them.
Obviously not true. -

Some of the most universally loved speakers measure like crap...
I have seen the graphs of several speakers I like and they all have virtually nothing in common. From my experience, I really don't understand what you would accomplish if you did have the graphs.... If it is curiousity then great, if not and you're basing buying decisions on them, well, a fool and his money are soon parted...There is no genuine justice in any scheme of feeding and coddling the loafer whose only ponderable energies are devoted wholly to reproduction. Nine-tenths of the rights he bellows for are really privileges and he does nothing to deserve them. We not only acquired a vast population of morons, we have inculcated all morons, old or young, with the doctrine that the decent and industrious people of the country are bound to support them for all time.-Menkin -
I can't believe Parson had the nerve to ask for a frequency response curve of the RTi12. How completely unreasonable. Damn you and your quest for knowledge.
[/sarcasm]
Taking multiple frequency response curves in your room can be great tools for learning about speaker placement and acoustic treatment at initial deflection points, etc.
Response curves can also give you an idea of how something may sound. Dr. Spec and COF's data measurements for the SVS PB10 helped me make an informed decision on my subwoofer purchase.
The one downside of measuring is it can really eat up time if you let it. However, with the stuff I have now, I can get an accurate curve in a second.

I don't think anyone is objecting to his request but rather his implication that they will tell you more about the quality and sound of a speaker than listening to them in your house would.There is no genuine justice in any scheme of feeding and coddling the loafer whose only ponderable energies are devoted wholly to reproduction.

Welcome to the world of compromise . The Polks are very good for the money, but in order to eliminate these little annoyances you need to step up the ladder until you are satisifed. No graph of frequency response is going to tell if the next set of speaks will or won't have the same issues. There is no standard, so it's impossible to look at several freq graphs and determine if you have solved any problems. They are good to use as one small piece of the puzzle if you want, but in the end it's what works (synergy) with your system and your environment heard thru your ears with your brain processing the info. It's not easy and it's very time consuming to find a rig that satisfies on every level. It certainly can be fun and frustrating all at the same time. There is no substituite for getting your listen on!
H9"Appreciation of audio is a completely subjective human experience. Measurements can provide a measure of insight, but are no substitute for human judgment. Why are we looking to reduce a subjective experience to objective criteria anyway? The subtleties of music and audio reproduction are for those who appreciate it.

It is always in the best interest of an audiophile listener to know the true frequency response of a speaker so that a baseline is determined. Without this, trying to correct for an end room in your house measured response is ludicrous unless equiped with a high end equalizer which most people seem to hate. How can you tell if an unwanted spike or dip is due to room acoustics or speaker design or electronics? If one measured his system then subtracted the true speaker response then one also has a true response for the rest of the gear which comes in handy when getting new speakers etc. Anyway here is a link to the excellent Polk Rti4 speaker.
