You're such a pain-in-the-*** Dean! []

My condolence to the Longworth's. Send those three to the gas chamber!

I am glad everything worked out for you Jeff. Sorry I did not get a chance to meet you face-to-face.

That sub looks as big as your room!

Happy Birthday, Dean! Enjoy your new life.

Rick, I'd buy it for you had I know your situation. [] Sorry, I have been away for so long.

Digital can be better but no one is willing to make it better. Really? I have all of these mediums at my disposal but vinyl wins me over every single time. Maybe I am getting older than I thought and my hearing is deteriorating at a greater rate, but all of these digital mediums just don't sound better than vinyl to my ears.

An eye for an eye? Aren't we a more civilized people?

The thought of you being deprived of Klipsch speakers bothers the heck out of me.

Jeff, I live in the Panhandle area only a few hours away from you.

Thanks to all those who served!

Jeff, sorry to hear about your loss. If you want, I'll send a pair of Heresy I or II (in great condition) down your way and all you pay is shipping.

I have all models in the Heresy line. In my opinion, the Heresy I with Alnico tweeter sounded the best. With 15 pairs of Heresy (2 pairs of Heresy III, 3 pairs of Heresy II and 10 pairs of Heresy I) in the last 9 years, you'd think I would know?

The movie is still awesome on small screen but LFE is rather disappointing! I've been looking forward to this movie the most. I will go get it today!

I am sure they will get things resolved in a timely manner. I've been running quad Epik Empires in my Home Theatre system for several months now without a single hiccup.

If you're mainly into home theatre and are willing to spend up to $1000 for a subwoofer then my recomendation is buy a new Epik Empire for $799. I am willing to bet that no Klipsch subwoofer in existence can ever hope to even meet the performance of (let alone beating) the Epik Empire for the money. Paying more for less and especially paying high price for a name makes absolutely no sense!

If you still have something sniffable, I'll send over my Bloodhound and the Desert Eagle .50AE!

To answer some of the questions: 1) I have a Radio Shack digital sound meter. 2) I have a Fluke digital multimeter. 3) My main receiver is a Pioneer model VSX-1020-K. (7 Channels with 80 Watts / Channel @ 8 Ohms.) 4) My surround wireless audio transmitter/receiver is a Rocketfish model RF-RBKIT. (2 Channels with 21 Watts / Channel @ 8 Ohms.) A 2 to 4 Channels with 50 Watt / Channel @ 8 Ohm surround wireless audio transmitter/receiver is virtually non-existent. It is impossible to find a surround wireless audio transmitter/receiver that match the per channel output of your main receiver. Hence, my question about the ratio between surround and main outputs. And my question about why surround wireless transmitter/receiver is so underpower.

I've been re reading the entire thread and thought about the original question over again and have a feeling that it has not been answered. So let me reprhrase the question in a different way. I need to ask the following questions first: 1) What is the ratio between the surrounds output levels and main output levels? 2) Why is wireless receiver outputs are so low compare to main receiver outputs? My main receiver can support 7 channels at 80 Watt/Channel with circuitry to prevent clipping. My wireless receiver can support 2 channels at 21 Watt/Channel with no circuitry to prevent clipping. The output of 1 channel on the wireless receiver is about 1/4 of the output of 1 channel of the main receiver. To connect the surround channels for wireless operation, you connect the left and right surround channels outputs of the main receiver to the left and right channels inputs of the wireless transmitter. Then you connect the left and right channels outputs of the wireless receiver to the left and right speakers. Now, during highly active scene full power is fed to the surround channels from the main receiver to the wireless transmitter. But only 1/4 power is going into the speakers from the receiver channels. So, if the transmitter channels peaked, would the receiver channel clipped? And if so, would this clipping cause damage to the speakers (most likely to the tweeters) since there is no clipping protection circuitry in the wireless receiver? And this is what I mean when I said receiver underamplification. However, can this even be possible? I don't know how wireless audio trasmitter/receiver work. But I assume that the wireless trasmitter can transmit a voltage higher than the wireless receiver can handle.

I did some measurements on my main receiver to see what kind of numbers I would get. At full power outputs of 80 Watts RMS / channel with all 7 channels active at reference level, 90dB is registered on my sound meter from the listening position (10 feet from the screen) during highly active seen with no explosion. I don't normally listen at reference level so I set at my usual listening level to -20dB and saw 75dB registered with the same scene. What do you think of these numbers?

Based on Quiet_Hollow reasoning, it is safe to say that I am okay. Another word is that, my current set up will not cause damage to my surround speakers in the long run.

Someone told me that overamplfication and underamplification either way are bad for speakers. I just want to make sure in my case it is not.

My main concern here is damage to the surround speakers (drivers especially the tweeters) due to under wattages delivered by the wireless receivers during extended listening sessions. Each of the two wireless receiver delivers a maximum of 21 Watts RMS into 8 Ohms per channel to a total of two channels. There is no clipping protection circuitry.

This should really be in the Home Theatre section but... Here's what my current 7.4 setup looks like: Main: Klipschorns. Center: La Scala. Surrounds: Cornwalls. Surround Backs: Heresies (for now, Cornwalls later). Plus two front Epik Empires and two back Epik Empires. All seven channels are active and driven by the main receiver of 80 Watt RMS into 8 Ohms per channel. I am feeding the surround and surround back channels into two wireless transmitters (total of 4 channels). The surround and surround back speakers are driven by two wireless receivers (2 channels each) of 21 watts RMS into 8 Ohms per channel. So while the main receiver is feeding full power into the surround and surround back channels at reference level via the transmitters, I am not get the same power outputs from the wireless receivers for the surround and surround back channels. Will this under wattage (lack of amplification power thereof) damage my speakers in the long run? My reason for doing this is because I don't want to run lots of wires from the front to the back of the room.

I am not sure I understand that. Also at reference level, the two back surround channels are active on the main receiver, but the power outputted on the wireless receiver will not be the same.
