TasDom Posted June 21, 2012 Share Posted June 21, 2012 I came upon a deal from an online retailer at www.acousticsounddesign.com selling brand new speakers that had been labeled "B Stock" because the cherry veneer was deemed too dark by the QC folks and saved a considerable amount. Congratulations! A lot of us have purchased thru ASD and are very happy. Some of us got A stock for B stock pricing when they were out of stock but I would have been just as happy with B stock. Same components so no difference in the sound quality. I think all are shipping much darker than the web sites indicate.......... Enjoy!

Tobias Posted June 25, 2012 Share Posted June 25, 2012 Hi. Is it possible to run the 7II's at 4 ohms with the AVR-A100? or I'm forced to use at 8 ohms? Thanks! Quote Link to comment Share on other sites More sharing options...
jvanhambelgium Posted June 25, 2012 Share Posted June 25, 2012 Sure I don't see why not. I read that the AVR-A100 is capable of running 4Ohm speakers. This means the AVR is capable of delivering high currents wheven an attached load (=speaker) dips to lower impedances at certain frequency ranges. It will in no way "harm" the RF7's Doesn't this receiver have a 6Ohm setting ? Only 4 or 8 ? Quote Link to comment Share on other sites More sharing options...

I also have a RC-64II, and a pair of 82II for surround. Quote Link to comment Share on other sites More sharing options...
W27 Posted June 25, 2012 Share Posted June 25, 2012 Yes it will sound different. It will be worse! Your speakers are 8 ohm... period. The settings on the back of the receiver are only to protect the receiver. Most basic receivers don't have large power supplies and enough cooling to handle pushing 4 ohm speakers hard. Lower impedance speakers will make your receiver run much hotter. Selecting 4 ohms on the receiver will actually limit the power to protect the receiver from over heating. My advice would be to leave it set to 8 ohms and see how it sounds. If you feel you need more power you should look into a separate amplifier. These speakers are very efficient, and do pretty well with receivers, but if you really want to use the full potential of these than a seperate amp is the way to go. Hope this helps Quote Link to comment Share on other sites More sharing options...
jvanhambelgium Posted June 25, 2012 Share Posted June 25, 2012 Will it sound different ? Don't really think so, unless you are really pumping high volumes, but even I don't think it sound different. When you configure the AVR at 4Ohm, it will be able to provide high current to the RF7 when you are really using them at very loud level (eg. when throwing a party...) I think the Denon can output 170W each channel at 4 Ohm (with a 1Khz test-tone) so you have slightly more power then the 140W at 8Ohm (altough the difference is probably not very audible ... it will be extremely L*O*U*D with these power-levels into RF7's !!) When configuring at 4Ohm you probably will be "stressing" the power-stages of you Denon more but it should be designed to deal with it, so don't worry. I've only driven my RF7's few times to the limits of my Onkyo 875 and I can assure you I had to put ear-plugs to enter the room !! Really, really LOUD!

jvanhambelgium Posted June 25, 2012 Share Posted June 25, 2012 Looking at the specs I see : 140 W + 140 W (8 ohms, 20 Hz - 20 kHz, THD 0.05 %) 170 W + 170 W (6 ohms, 1 kHz, THD 0.7%) So it seems to be able to deliver 170W /channel at 6Ohm compared to 140W at 80hm But yes, the power-supply stage will be more stressed ;-) that is true. There is the increase in "total harmonic distortion" (altough once measure across 20-20kHz and elsewhere with a 1Khz tone) but I'm not sure if it really can be heard...

Tobias Posted June 25, 2012 Share Posted June 25, 2012 Thanks guys! My last question: is it safe to test the speakers at 6 or 4 ohms? (for the speakers and receiver) Quote Link to comment Share on other sites More sharing options...
W27 Posted June 25, 2012 Share Posted June 25, 2012 Like I said... the speakers are 8 ohms. If you read your owner's manual it will explain the settings. They are only to protect the receiver. It will not hurt to try the different settings as long as your impedance is above the setting you select (which they are) but there is nothing to be gained. The receiver won't gain any power, if anything you'll notice less. The switch doesn't make your speakers 4 or 6 ohms. Quote Link to comment Share on other sites More sharing options...
Tobias Posted June 25, 2012 Share Posted June 25, 2012 Thanks again. I tested, volume from -30 to -10 in stereo, I didn't notice any difference... [] Quote Link to comment Share on other sites More sharing options...
Eccentric Dyslexic Posted July 13, 2012 Share Posted July 13, 2012 Hi all, My speakers have arrived and i am in audio heaven! Never before have i felt so immersed in perfectly balanced sound..these speakers are fantastic! Really difficult to photograph in my home cinema room as all the walls and the ceiling are covered in the blackest black velvet! Just fiddling around with settings in Audyssey on my Onkyo 5009 amp. These RF7IIs do go down low so integrating them into the eight X 18" driver Infinite Baffle subwoofer system is going to be interesting! Steve:) Quote Link to comment Share on other sites More sharing options...
TasDom Posted July 13, 2012 Share Posted July 13, 2012 My speakers have arrived and i am in audio heaven! Congratulations Steve! They look fantastic with the color of your couch. Very Nice! Enjoy! Quote Link to comment Share on other sites More sharing options...
Heritage_Head Posted July 29, 2012 Share Posted July 29, 2012 So with the projector screen going up I need as much flexibility as I can get with the rf-7ii placement. I personally like the feet on them but it makes it harder in that spot to place them with the feet sticking out against the wall and sub (I want to angle them in as much as possible). So I flipped them over to look at my options. My original plan was to call klipsch and see if I can order some front feet and put them in the back. But after pulling it all apart and adding a few longer machine screws I was able to use everything to get it to match. So for those that would rather have matching feet in the back to the front here are some pics on how I did it. First pic shows taking out the two screws that holds it in (if you bought them new you put them on yourself). Quote Link to comment Share on other sites More sharing options...
Heritage_Head Posted July 29, 2012 Share Posted July 29, 2012 Next you need to disassemble it. You need a star bit to unscrew it (I found a rusty one in the bottom of my tool box and amazingly it’s the right size). [] Quote Link to comment Share on other sites More sharing options...
Heritage_Head Posted July 29, 2012 Share Posted July 29, 2012 Next line it up like this and use one of the original screws on the inside hole (outside one for the foot). Quote Link to comment Share on other sites More sharing options...

Heritage_Head Posted July 29, 2012 Share Posted July 29, 2012 Fits pretty nice only drawback is you can’t put spikes on them. Quote Link to comment Share on other sites More sharing options...
Heritage_Head Posted July 29, 2012 Share Posted July 29, 2012 For those with wood floors I would use flat head machine screws and not the rounded head type. It clears even with the rounded head but just to be extra safe I would go flat head. Quote Link to comment Share on other sites More sharing options...
