kriller7000dk Posted December 12, 2010 Share Posted December 12, 2010 Has anyone tried the Dean mod the new RF-7 II. Will it get the same results and impressions with the new crossover or isn't that different from the original one? I have no technical insight to understand how it works, but will RF-7 II be even better with the tweak? Thanks Kristian from Denmark Quote Link to comment Share on other sites More sharing options...
Zen Traveler Posted December 12, 2010 Share Posted December 12, 2010 Trey Cannon (Klipsch) came on and said the RF-7IIs have a new crossover that addresses the issue that dean's crossovers seemed to help on the older version, from what I understand. {EDIT: Btw, do you own the RF-7II and notice a problem?

But they are brand new and haven't played for very long time. So i don't think it's necessery to do the mod. Was just curious to know. Btw - how many hours should they play before they are in top condition and not expect more of them? Quote Link to comment Share on other sites More sharing options...
Zen Traveler Posted December 12, 2010 Share Posted December 12, 2010 I wouldn't think your RFIIs would need an upgrade, but then again, I didn't think (and am still not sure that) mine did either. [H] Insofar as break-in time, I have been convinced that they don't need a break-in period and it's your ears that either will/will not adjust. Btw, congratulations on your speakers.

Not sure i agree on that;-). After played some hours they plays better and better:-D. Is there something i should be aware of when bi-amping? Because on klipsch.com in the spec it's written that they could be bi-amped,bi-wired but the owners manual has nothing about bi-amping. What should i relate to? Thanks hope they will be THE speakers for many years. Quote Link to comment Share on other sites More sharing options...
Zen Traveler Posted December 13, 2010 Share Posted December 13, 2010 Well...If you don't agree with me on break-in period you probably won't appreciate my opinion on bi-amping or bi-wiring, but I would keep the jumpers on and run one set of wires from your power source to your speakers.

Zen Traveler Posted December 13, 2010 Share Posted December 13, 2010 and why would you do that? Because the RF-7's horn don't need that many watts and the LF drivers only benefit minimally, if at all....From my understanding if you wanted to use an external crossover then bi-amping would be something to consider.

Thanks hope they will be THE speakers for many years. About a week. But there is a funny thing I truly believe its the ears. I owned the RF-83 and I brough them to college, left them during winter break came back damn these sound different. a week later I am back to these are sounding good again. it was more apparent when I went home for the summer because I had to box them up and did not have room at home. When i unboed them in the fall boom again not sounding like I remembered and a week later all was well. Quote Link to comment Share on other sites More sharing options...

If you do not take the crossover out and try to "bi amp" you are just doing fools bi amping and possibly damaging the amps and crossover. You are basically throwing double the power to a single source. The 4 posts were meant to bi wire which some people believe gives a better signal (though physics would say otherwise) They believe that giving a speaker 4 wires gives the electrons better connection or flow to the speaker. I did not realize though that electrons had feelings? Quote Link to comment Share on other sites More sharing options...
garyrc Posted December 15, 2010 Share Posted December 15, 2010 Insofar as break-in time, I have been convinced that they don't need a break-in period and it's your ears that either will/will not adjust. Two related questions: 1) Has any lab or manufacturer set up two large sets of speakers, all the same model and production run, and run one set through a lengthy break-in (burn-in) snd left the other set totally unplayed (except for initial testing), then played them for critical listeners without revealing which went through the break in and which did not? Could the listeners hear the differencein a way that exceeded chance? I, too, have thought I heard differences after considerable running time, but I don't know if the difference was a real difference in performance of the components, or psychological adaptation. 2) I have the same question about warm up periods each time one plays music. Does the reproduction sound better after warm up, or are we just used to its characteristics after listening a while? My guess is that it might make a difference with tubes, or anything else that changes temperature greatly between the time it is turned on and when it is warmed up (thus the term), but I wonder about solid state components, speakers, and the like. I have difficulty with the contention that interconnects and speaker cables sound different after warm up. Quote Link to comment Share on other sites More sharing options...
Mighty Favog Posted December 15, 2010 Share Posted December 15, 2010 I know one of the "Audo Salons" in my area will come to your house if you spend enough money to correctly set them in place and do the burn in so you can enjoy them right from the begining.

Klipsch Employees Trey Cannon Posted December 23, 2010 Klipsch Employees Share Posted December 23, 2010 Ok, there is such thing as break in , but we do it in 20 min with 75% `input voltage at 20Hz. The complance of the woofers is where you would see the change. However, with that said, after 8 hr at 32V they had about 1 - 1.5db more output gain...not a lot of change. jay said : "You really cannot bi amp these speakers. The crossovers are beyond the jumpers. If you do not take the crossover out and try to "bi amp" you are just doing fools bi amping and possibly damaging the amps and crossover. You are worng. you can Bi-amp these speakers. It's called "passive bi-amp" where you use 2 amp channels for one speaker. And NO it will not hurt the speaker or amp Channel. True, there is not much advantage to it. I have seen tubes on the HF and SS on the LF. I have seen 3:1 power ratio so you can have more LF at low volume, but a bass knob can do the same thing. If you connect the HF section of the speaker to an amp, the amp will see the 8 Ohms + network load. If the LF section is connected the amp will see a min of 4 Ohms + network....but both will work just fine.... And NO there is no need for the "Dean G Mod". That was "fixed" with the new HF, LF drivers and network. Quote Link to comment Share on other sites More sharing options...
jacksonbart Posted December 23, 2010 Share Posted December 23, 2010 personally I didn't think there was a need for the Dean G Mod for the original RF-7s. 1 Quote Link to comment Share on other sites More sharing options...
Jay481985 Posted December 23, 2010 Share Posted December 23, 2010 http://music-electronics-forum.com/t3639/e And NO it will not hurt the speaker or amp Channel. As with that I was hinting at the fact that you can exceed the rms wattage because you are doubling your power if you use the same amp. So more or less in scenes that demand it, it can cause damage.

garyrc Posted December 23, 2010 Share Posted December 23, 2010 Thanks Trey and Jacksonbart. Trey, [Edit] Oh, on re-reading, I see you used 20 Hz, so only the woofers would get the signal .... Has Klipsch tried breaking in midrange drivers & tweeters? Even though there were no woofers involved, did the AK-4 upgrade kits get some kind of break-in? Does Klipsch still match pairs of speakers? Were the AK-4s matched? My two sound fairly different in the highs, but so did my original Khorn tweeters (c1982). Thanks. Quote Link to comment Share on other sites More sharing options...
Deang Posted December 24, 2010 Share Posted December 24, 2010 "And NO there is no need for the "Dean G Mod". That was "fixed" with the new HF, LF drivers and network". Also, it's not possible to apply the mod to the new network, the two networks are completely different. However, if I owned a pair I would still replace the Mylars on the HF board with some nice polypropylenes. I've said many times that the the original RF-7 sounds really good right out of the box. That it sounds better after the application of the mod and replacement of the caps and resistors doesn't change that. The RF-7 responds well to the changes because it's a great speaker to begin with -- you can't dress a turd. I would love to hear the new iteration, I bet it kicks.
