Your receiver is over 30 years old. Chances the caps in the protection circuit may need replacing along with adjusting the DC balance and idle current of the power amp. I suggest you post in the Pioneer Audio section of AudioKarma, very knowledgeable people over there: http://www.audiokarma.org/forums/index.php BTW I still use my SX-1980 and still love it.

Here are a couple of pics of my Fortes which have been modified for bi-amping:

I'm interested. Looks like you have an all-grain setup. I have some equipment but not all to brew all-grain. I would be interested in more info/pics of your brew setup.

I did the same when I modded my RC-7 crossover: http://forums.klipsch.com/forums/p/135665/1374176.aspx#1374176 You have certainly been busy modding your crossovers and Emotiva gear. Hope you have a chance to sit back and enjoy all your hard work.

Sorry for the offensive remark Dean. I didn't compare them side by side, in fact they were in totally different environments but my comment was in reference to the smooth high end of the modded RF-7 vs the RF-83, especially if you drive the RF-7 with a tube amp.

1. That you are single. 2. I wouldn't want to have a stereo war with you.

Hook it up in place of one of your main speakers and play music through it. If it sounds normal then it isn't your RC-7, it may be your A/V receiver. If you still have the "tweeting" sound then you can remove the crossover from the back and disconnect each speaker one at a time to help determine the source of the problem.

SET12 was the one who suggested adding the resisitor to my Dynaco. I put a 16 ohm loading resistor (two 8 ohm resisitors in series) across the output of the Dynaco amp. No mod to the crossover required. Here is the thread: http://forums.klipsch.com/forums/t/132967.aspx?PageIndex=1

I've heard frankphess DeanG RF-7's with his VRD monoblocks and I was impressed with the low end, it sounded very natural and extended lower then any tube amp I've heard. Then again I've never listened to the Silver Seven's.

I have my Forte's bi-amped (Dynaco ST-70 on the mid/highs Pioneer SX-1980 on the lows) and never looked back.

My Dynaco ST-70 has no problems with the RF-7's, since the Dynaco is only driving the horns on the RF-7's it is hardly being pushed causing the Dynaco to run at class A. Since the HF crossover section is a capacitive load I installed a 12 watt Mills resisitor across the speaker outputs on the tube amp to create a resistive load on the tube amp. Glad to hear that the resisitor mod made a big improvment.

Since I just replaced the Caps & resistors on my RC-7 I don't have the inductor values but here are the capacitor& resisitor values: Low Frequency Section: Resisitors: 1.5 & 2.0 Ohm Capacitors: 24 uF & 28 uF High Frequency Section: Resisitors: (2) 2.0 Ohm Capacitors: 3.75 uF, 12 uF, & 18 uF. Resistors are 10W, Capacitors are 100V. Here is a write-up I did modifiying my RC-7 with pictures. http://forums.klipsch.com/forums/p/135665/1374176.aspx#1374176

Welcome Andrea, The caps have the values in MFD on them along with the voltage rating. If you are just replacing your caps then you won't need a schematic for the value of the inductors. I have DeanG crossovers in my RF-7's and modified my RC-7 and I am very happy with them. If the RC-7/RF-7's seem a little bit on the bright side, I would recommend the resisitor mod that DeanG uses. The mod makes the RC-7/RF-7 sound more like the RC64/RF-83's.

That's what I told myself, I ended up installing spikes on my Forte's, inexpensive improvment that was worth it.

MissMiller, Klipsch speaker use a seperate crossover network "box" instead of soldering components to the drivers. My suggestion would be to keep your phone away from your home theater system. I have listened to a Logitech squeezebox: http://www.logitech.com/en-us/speakers-audio/wireless-music-systems/devices/5745 that can play wi/fi/mp3 music through your system from a computer. Provided you can connect a seperate amp to your Sony A/V receiver, a popular amplifier that has good feedback are the Emotiva amplifiers: http://emotiva.com/xpa3.shtm The XPA-3 is a 3 channel amp that will drive two main speakers and the center channel, the XPA-5 is a 5 channel amp both with pleanty of power. I don't own Emotiva amps but I have listened to them and I am impressed with their sound and build quality.

My DeanG RF-7's sound very similar to the RF 63/83's. Dean uses a resisitor to bring down the horn resonant peak which may account for the harshness you are hearing. I highly recommend the DeanG x-over upgrade to your RF-7's and would also recommend a tube amp running the modded RF-7's. Search for (DeanG RF-7) and you will find more favorable posts.

Several years ago I bought Styx Equinox CD, previously I originally owned this album on 8-track (don't laugh it was my very first stereo system). To this day when I listen to the CD I am waiting for the song to fade out to switch tracks. I can still tell (when I listen to it) which songs and exactly when it was about to switch tracks but of course the CD version doesn't switch tracks. Glad you and your wife had a great time, unfortunately my wife and I don't have the same taste in music. At least my middle son and I share the same music taste.

Any updates on the concert? Hope you had a great time.

The best part of this concert is that they are playing at a small (4600 seat) theater venue. For both concerts I have center section balcony seats, my son and I prefer acoustics over how close we are to the stage.

My son gave me the Snakes and Arrows for fathers day, I feel that this better the the R30 DVD I own. I remember back in the day my chest pounding to Neil Peart's double bass drums, hopefully I can experience that again even though Neil is down to one bass drum.

Is that possible ? My wife gave up on trying to shout above my music, now when I turn up the volume the doors in my house slam shut even if they are already closed.

I enjoy the bands from the 70's/80's. July 5th I am going to see Rush with my 21 year old son. The last time I saw Rush was back in the late 70's when I was in high school. I also have tickets to see the Scorpions in August, Michael Schenker Group is the opening band.

I could easily see myself needing a divorse attorney if I went that route.

I know what you mean by "Significant Other". I still don't believe that there exists a girlfriend/wife who is an audioholic. Regarding the "ultimate" set of components and upgrades to the Forte reminds me of SET12's setup: http://forums.klipsch.com/forums/p/132614/1345695.aspx#1345695 I havn't heard his setup but now people who have (like SWL).

Could it be that he is missing the jumpers on the RC-64?
