Cleve Posted February 8, 2006 Share Posted February 8, 2006 I haven't been frequenting the forums here as much as I once did. I see that the new Reference line of floorstanding speakers has launched, and that the old RF-7 and it's siblings are now discontinued. I was looking at the new lineup - I must admit initially I was a tad confused as to which is the "top of the line" floorstander. I thought, because the number was higher, it was the RF-82, but it's quite a bit smaller than the RF-63. It was a break from tradition, from the Epics to the KLFs to the last Reference speakers - in each series the top of the line had the higher number (CF-4 > CF-1, KLF-30 > KLF10, RF-7 > RF-3). The new numbers obviously refer to the size and number of woofers. Oh well, so much for tradition. I looked at the specs closely of the RF-63, and compared it to the RF-7 RF-7 102 dB/w efficiency 250 watts continuous power handling 4.8 ft3 enclosure 157 sq inches bass radiational area 32 hz - 20 khz +/- 3dB Weight - 90 lbs RF-63 99 db/w efficiency ( RF-7 is 3 dB more efficient) 175 watt continous power handling ( RF-7 has 43% greater power handling than the RF-63) 4.4 ft3 enclosure (RF-7 has 9% more cabinet volume) 99 sq inches bass radiational area (RF-7 has almost 60% more bass radiation area) 30hz -21 khz +/- 3 dB Weight 82 lbs (RF-7 is almost 10% heavier) So there it is. The RF-7 seems superior (at least on paper) in every design parameter to the RF-63. The RF-63 is less efficient, and it also has greatly reduced power handling capacity, so it's dynamic range is less. At low volumes perhaps it can produce as much bass as an RF-7, but absolute bass production for the RF-7 must be significantly higher - it has much more woofer area, a bigger enclosure, higher power handling, and greater efficiency. I'd guess the woofers on the RF-63 would be clicking and bottoming out long before the RF-7s would be begging for mercy. I'd compare the RF-63 to my CF-4s, but that would be needlessly cruel. So what's the list price on the RF-63s? I would think it would have to be a lot less than the RF-7s. Was this a price point adjustment to position them differently against the competition, or is there another rationale in downsizing and derating the flagship Reference speaker? What's anyone elses thoughts about these speakers, and the rest of the Reference line? Quote Link to comment Share on other sites More sharing options...
