Yes. I noticed you own the same sub. Have you noticed any differences in bass output and/or sound quality when placing the sub directly in the corner of a room? Mines is actually between the TV stand and the left front speaker, and I just refuse to move it unless its actually worth it since I would need to possibly purchase another [good] power strip, and use some rg6 coax cable to get it as far away from the receiver as it would have to be.

Not exactly. It's basically rerouting the power originally meant for the Back R/L, to the front speakers. So it's as if the receiver was only capable of 5.1, as opposed to 7.1, so there is no rear surround signal being sent anywhere.

I can honestly say I was one of those who couldn't do without that "upside down bell" curve. As a matter of fact, I have the logitech Z-5500's as computer speakers, and this is what my media player's equalizer is set to look like (only not as much of a curve as it use to be). Currently I do use the Flat YPAO and only modify the sub to provide a bit more of ultra low bass ( you could never have enough [] ), but other than that, the rest of the speakers sound fabulous. As to priorities... I might be looking towards purchasing the Emotiva if it gets me a resonable amount of improved sound quality. I just don't want to spend $800, and hear very little to no difference.

Very interesting. Then what in the world is that 700W peak power that is stated on the specifications all about? It's a hell of a lot higher than the 175W RMS [:^)] . I wouldn't blame the auto setup, it does a pretty good job of equalizing all speakers in my opinion and seems pretty consistent when I do multiple tries. The speaker sounds great, don't get me wrong, just not as impressive without the equalization (at least to my taste), it's a great sounding speaker, very powerful, very efficient. So in other words, the sensitivity is what determines the volume when a given amount of power is applied to it? Never knew this, Thanks wuzzer. Does this ultimately determine how loud a speaker is as well? Meaning, can I expect my RF-63's to produce 99dB, and the RT-12d 120dB? I'm just trying to understand the basics here... [:S]

Yes Bill, it always has been, plus I just recently adjusted the speaker to make sure it accuaratly pointed towards a listeners ears.

What I meant is that maybe since the sound coming from the center is so much lower than the rest, that the receiver might be mistaking it for a much smaller speaker. It's not that the speaker sounds completely dull, its just that without equalization, during listening tests, it's noticeable that the sound is not as bright as the rest of the speakers and this is specially noticeable during the white noise produced during the autosetup process (where each speaker should sound just about the same). But then again, maybe it's meant to sound this way [:S] I don't know, which is why I ask to see if others have experienced the same. PS - I'm not complaining about the center sounding bad, since equalization makes up for it. Just wondering if a lack of power could limit the harmonic abilities of the speaker [:$] as stupid as that may sound to you guys (since I obviously know much less than all of you about this stuff).

I've had my sub working for 7 months now with only one of two possible inputs (I use the Right input for no particular reason). I was wondering if using a Y splitter would make a difference and possibly provide a better input signal to the sub. I was also considering moving the sub farther from the receiver and using some rg6 coax cable (the kind my cable operator uses). At this point I'm using a Monster coax cable, but I'm not sure if moving to the rg6 would degrade the sub's sound quality.

It certainly is there. I imagine that without this, the tweeter would not get any power. But yes, the plates are there since I never planned on bi-wiring or bi-amping the center (I wish I could, but the amp only does this for the front speakers).

The grills are always off on the front and center speakers, and I always make sure that all drivers [on all speakers] are working. It it a bit strange to me that out of all speakers, the biggest and baddest one, doesn't sound at bright as the rest. My best guess is that it's not getting enough wattage as opposed to the rest which need less of it (175w for the fronts, and 150w for the rears. The center needs 200w) [:^)]

Something I have noticed, specially when listening to the "white noise" that receiver produces during the auto-setup, is that out of all speakers, the center (RC-64) sounds much duller than the rest. You seem to have a similar setup, so I was wondering if you experienced anything similar when running all speakers from the receivers amp? Also, this morning when I ran the auto setup with no sub, it set each speaker to "big" except the center, which it considered as "small". Since this speaker requires more power than the others (200w RMS), could this be prove that the receiver is simply not giving it enough juice?

I think I need to apologyze here. I wasn't too clear in my previous explanation.When I said that my RF-63's weren't giving much bass, I had already in fact muted the sub, set the speakers to "big", disabled the crossover function on the amp as well as the equalizer. Regardless, I did listen to you guys and tried it again this morning. The bass was there (not as deep, but it was there as much as I guess it should be). The room where the speakers are located is somewhat unusuall so that could be another reason (I know having them near the corners would yield better bass output). I must not have noticed much bass before since I was coming off from listening with the sub on. I was never really used to the fronts alone since I never set them up until I had them all, including the sub. I guess I can't complain. Music sounds awesome, and more so does blu-ray (I still can't get over how unbelievably clear and detailed everything sounds)[].

I'll deffinetly try what wuzzzer suggested and giving the port some additional "headroom" back there. At this point the speakers are about 2 feet away from the back wall. I do seem to get a good amount of decibels going, it's just the fact that I'm not sure if there is any clipping, or anything like that going on. Distortion I wouldn't expect since none of the speakers are handling much bass, or are you referring to some other king of distortion?

Oh no, don't get me wrong, I get PLENTY of bass (from the sub). What I mean is that if I completely lower the sub's volume, there is hardly any audible bass coming from the fronts. BTW, I'm a newbie here and I haven't the slightest idea what IMO or IMHO means... and the configuration settings that you're suggesting have always been in place [speakers set to small, receiver crossover at 80Hz, and no limit on the sub's crossover. Perhaps I should do some further testing since during a bass test, I believe all the bass I get comes directly from the sub, and none form othe fronts (I never really bothered testing as it all sounds ok to me).

Yes, the fronts are actually bi-amped since the receiver allows for this configuration as long as you're not doing 7.1.

Recently I had the urge to read about amplifiers (the one piece of equipment that I don't have but somehow felt I should). Before I get started, this is what my setup consists of: RF-63 Fronts RC-64 Center RS-62 Rears RT-12d Sub Yamaha RX-V3800 Receiver ... the rest is irrelevant at this point. My main concern here is that apparantly what Yamaha claims to be 140w x 7, may not actually be that, but much less. In fact I found a site where someone stipulated 110w x 2, or about 85w x 5. Now, it's a knows fact that underpowering speakers causes clippling as well as god knows what other terrifying events. At this point I am getting somewhat paranoid considering I may slowly be destroying my investment (a set of speakers that I'd drooled over for years). The fronts are bi-amped and the sub does most of the hard work, but apparently this isn't enough. I've been reading around the forum, and it seems that the Emotiva xpa-5 would be a great fit; enough to feed each speaker 200w. Would this actulally be a sound investment? And would I even be able to hear a difference in audio quality? [:^)] This may also be the reason why the fronts (on their own) lack much bass. Originally I thought it was the placement of the speakers, since they are not directly on any corners, but a few feet away from the back walls.

What causes clipping and how would I avoid it? I think I once read that setting the equalizer settings high on any frequency would also cause clipping. Is this also true?

I just purchased a new system consisting of: Yamaha RX-V3800 (140w x 7) RF-63 (pair) RC-64 RS-62 (pair) (And should receive the RT-12D by tomorrow) I've been reading in different forums how the receiver's power should exceed that of the speakers. Since my Yahama only provides 140w (supposedly), and the RMS power rating of the RF-63's is 175w, is this something for me to worry about if I was to drive the speakers at a high volume? Another thing about this is that since I am ony using 5 channels, the receiver allows me to redirect the other 2 remaining towards the front speakers. This would basically give the RF-63's a total of about 240w each. Would it a be a good idea to go ahead with this, or would it really be too much power for the speakers to handle at low or high volumes? I've already tried out all the speakers, but not all at once since I will be moving shortly and need to have everthing packed up and ready to go. The speakers sound nothing short of amazing. I still can't believe how great they sound without the need to make any adjustments to the equalizer settings. But I am just worried that I'll do something wrong and mess up my new system. Any help is well appreciated.
