What was driving those RB-5's? ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

Spider, How do you know this, can you measure this easy ?? It would be the same for the RF-5 since they use exactly the same woofers. For the RF-7 it will propably even wors as they use even 10" drivers. ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

Way to go mace. Don't mind the wife and find a good place. It can make a difference!! ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

Oh boy, Oh boy I don't understand this debate between HT and stereo Music. It is all sound. On the other hand I do understand the quality difference between components but that doesn't mean to give HT. It is music to. Never heard music tracs in movies ????!!!! So it is better to debate how much to spend on a (HT) system that can reproduce any sound, 2 channel or x-channel. How far do you have to go. My (HT) system costs me about 6000 $. It sometimes terrifies me thinking I spended 6000$ .... But then, a lot of people are paying much more for just 2 channel. Is it better than my system in 2 channel. Sure, but how much? Once I went to an audiofile evening to hear some very expencive speakers (B&W nautilus 803 4300$ ; Sonus Faber Guarneri 6400$; Electa Amator II 2150$??) All driven by a Rotel RMB-1095 amplifier(2300$) and Sony TA-E9000ES/N pre-amplifier(2000$). Ok, the sound was good, very good. I liked the nautilus 803, but wasn't that impressed considering the price tag. Ok, I never heard a Klipchorn or a LaScala. That is maybe something different. I am very happy with my current system also for 2 channel. Amen ... ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

Hey ajstrother, Go with another pair of RF-3's (and save some $), specially for 5 channel stereo. Also for surrounds it is IMO better to match the system as good as possible. ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

Use spikes always !!! Spike your speakers on a solid underground like a marble plate. I used also the rubber feets with my RF-3's. Recently I gave my front RF-3's a large polished granite circle of 18" diameter. I removed the plastic feets and screwed the spikes directly into the threaded holes of the RF-3's. Not only the looks are better but also the sound. Nice accurate bass response. You will hear the difference. Now they have a real foot !! I will post a picture of that soon. ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

Yep, bare wire. But on some amplifiers you have no option and forced to use bananas or spades, specially when bi-wired.(Rotel RB-985 MKII) With my onkyo no problem. Al my speakers are bi-wired (bare wire)!!! ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

The onkyo's have WRAT. (Wide Range Amplifier Technology) They start from 20 Hz and go up to 100kHz !! But these are cut off frequenties, so they go beyond that. It is nice to be far from these cut off frequencies so that distortion in the operation area is almost absent. Like Kevin Said: "Many less expensive receivers and some tube amps quote power spec's using a low end frequency cutoff higher than 20hz. I suspect that their power and/or distortion levels deteriorate quite rapidly below their cutoff point, so they raise the point to where the specs are better." They give just the range of flat response. ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

Hey Spider, That is a good question. This would give you an idea how difficult the speakers are to control by the amplifier. So I extend this question to the RF-3's. ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

Ok, I just borowed this test equipment. It was the SPL meter and a test CD with over 90 numbers. I don't remember the titel but it started at nr 47 with the 150 Hz down to 16 Hz at nr 72 in 5 or 10 Hz steps. Each tone was about 20 seconds. From nr 73 (440 Hz) it goes up to 20kHz (nr 92)as the first post of this thread. My DVD player is digital connected (with IXOS digital coax interconnect) to my receiver which is set in direct mode. With this I think the source is OK and also what is send to my RF-3. So it has to be the SPL meter. Even my ears can still hear the 18kHz out of the horn. The 16kHz will drive me nuts. While it was fun playing around with this meter I will give my ears always the final judgement. Hey, the RF-3's are (musicaly) very nice speakers !!!! Thanks for the replies. ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

Hey Seb, I know that, but this is al lot of attenuation in the highs. More than 10dB and measured right at the horn so that the room is more or les out of the question. I measured this also at about 30cm (12") right in front of the horn tweeter. I am certainly not complaining about how they sound. They sound very good. But this is just a technical issue. Thanks for the reply. ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

Hey, I was expecting lots of replies on this one??? I am serious here, has anyone don this already?? Is that Radio Shack SPL meter accurate enough??? I asked someone to do the same on his Nautilus 803's!! I will post his results as soon as I get them. ( It could be the SPL meter ) Please some comments ... ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

Hi Neighbour, Why going from 5.1 to a stereo amplifier? For 5+ channel receivers check the onkyo's(DS676, 696, 787, 989) or denon's For high quality (pre-)amps check Rotel (www.rotel.com) (Waarom upgraden, de RF-3's zijn goed ) Why are good greetz USparcje ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

I was playing around with a Radio Shack SPL meter to help me giving my speakers a good place. While testing I noticed that the sound pressure in the highs drops from 14kHz. Surpriced by this I ended up measuring just one RF-3 at 1m distance at horn level. With this setup I measured just the frequencies that the horn is suposed to reproduce. Results: Hz dB 3150 78,5 6300 86 10000 83 11000 81 12000 83 13000 80 14000 78 15000 76 15500 75 16000 74 16500 74 17000 76 17500 74 18000 76 18500 77 19000 76 19500 69 20000 71 The 1000 Hz is set to 80 dB as reference point. What is going on here? Any comments on this one??? Moderators, some technical advise here please. ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

Hi vision, loud and clarity. That is what you find with the RF-3's. But I don't know what 500 dollars will do. I still have to listen to the RF-5 and RF-7. My local dealer will get them in about 2 weaks from now. Are they better?? Just listen ... ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

Hi all, THX, it is al about the movie experience. To ensure that you will experience this the equipment(speakers ,amplifiers,...) must meet certain acoustic criteria. THX certified equipment should meet those criteria. For amplifiers it means that they can assure a wider dynamic range and more faithfully reproduced sound, plus adequate power for the room size. That is why that THX certified amps or receivers have at least 100W real power/ch. BUT I am wondering why THX label on different equipment. It doesn't make much sense to put THX labels on different equipment. It is the complete system that has to reproduce the movie experience not just one component. Ok with THX certified components it is propably most likely it will be, but there are a lot of speakers that don't match with certain receivers. Not to mention the speaker placement. It all depends ... Just listen to a complete system and put the THX label yourself. By the way onkyo has also non THX receivers: DS676, 696(new) They will handle the dynamics on those klipsch Reference without any problem. In any way test the receiver first with the RP-5's. Don't mind THX. ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

DwK, In this connection you have 2 line level controllers (pre-amplifiers). One that controls the headphone output(your boom box??). This headphone output goes to the line level controller(pre-amplifier) of the promedia's. In eather way, which one you use to control the volume the result is the same. ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

DwK, The motorboard is the front plate where the horn and the woofers are attached. Refered to as motorboard because it is a board that carries the drivers(=motors) MDF stands for Medium-Density Fiberboard. MDF is made from fine wood dust mixed with a binder and heat-pressed into panels. ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

BobG, About that port thing on the RC-3. I just wanted to point out a minor mistake on the specification features of the RC-3 on this web site. Moreover I never would alter a klipsch speaker. They are designed by klipsch and stay that way. As you said Minor tweeks are fine. HornEd, Tapered array or not, it's the sound that counts ... ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

Dwk, What you are trying to do is impossible!! You gonna blow some fuses. What seb stated is correct. An amplifier can have only line level input provided by a pre-amplifier that controles the line level. The amplifiers you mention will amplify the input by a fixed amplification. So you can connect each speaker to separete MC1000's or just one MC7106. Bi-Amping is when you biwire your speakers and connect the highs to one amplifier and the lows to another amplifier. So you can by two MC7106's and connect all the highs to one MC7106 and the lows to the other. Or two MC1000's per speaker. ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

Fountain , You are right, the only speakers that would match are the RF-3's. It is just not only great for movie but also for 5ch stereo. But you have to be able to put them well behind the listening position. For the center also an RF-3 if it was feasable to put it invisible in front of the screen. Maybe you should wait for the RC-7 and compare it with the RC-3 in your system. RC-7 looks a good match for the RF-3's. About the sound ??? When it is at my local dealer I'll get one for auditioning it in my system. ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

The C-7 has a tapered array (so is the new RC-7), the RC-3 does not (I tried one before finding the C-7). Sorry HornEd, but you are wrong here. The RC-3 has infact also the tapered array. Look in the technology feature of the RC-3 or in my thread "What 's wrong with the RC-7.... ". In this thread PhilH stated that the RC-3 and RC-7 have the tapered array. I give this last one because when I went to the "Technology features" of the RC-3 to see if the Tapered array was actually there(and it is) I also noticed that there is a big port. I know mine doesn't have one and the specifications mention that the RC-3 is a sealed enclosure. Should I drill the port myself??? Moderators can you clear things out. About the 2 center speaker you are absolutly right. Also I am very eager to hear the RC-7. It is almost an RF-3 and the specification let me know that it would be a very good match for my RF-3's. ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3

Can you ever have too much power??? NO NO NO NO It is not just the specified power rating of your amp that counts!! You have also take in acount the behaviour of the speaker. It is a dynamical system and that is why you have to be careful in matching speakers and amplifiers. Most amplifiers are rated at certain standards like DIN, but don't be surprised if the amplifier gives only about less than half of it's power at a different impedance and phase shift. I don't know about the RF-3's. Do they stay at 8 Ohms all over the range??? For the highs propably no problem, what about the woofers?? In eather way my Onkyo seems to give them what they need ------------------ ------------------------- Receiver: Onkyo 676 DVD: Pioneer DV-525 Screen: Thomson 46" RetroProjection Front: RF-3's Rear: RF-3's Center: RC-3
