Zappa Freak Posted May 13, 2016 Share Posted May 13, 2016 What would be a reasonable amount of receiver watts to push a pair of KG- 5.5 75 Watt amp? Quote Link to comment Share on other sites More sharing options...
The Dude Posted May 14, 2016 Share Posted May 14, 2016 Mcintosh has to be one of my favorites. If out of your budget, give crown d45 or d75 a try. Sent from my SM-N920P using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
Fjd Posted May 14, 2016 Share Posted May 14, 2016 (edited) To paraphrase those indelible words uttered by the one and only Sargent Shultz and parodied by good old Arte Johnson, "Very Interesting." Several of us have been responding in the thread below. It seems that instead of a "double post" it looks like he got a "double thread" that posted one minute apart. https://community.klipsch.com/index.php?/topic/163961-good-watts-for-kg-55/ Edited May 14, 2016 by Fjd Quote Link to comment Share on other sites More sharing options...
BusaDude Posted May 14, 2016 Share Posted May 14, 2016 75 watts would do quite well... They were rated for 100 wpc continuous and 500 watts peak. I've always preferred to have a little too much power versus not quite enough. But go with what sounds good to you. https://web.archive.org/web/20120928054057/http://www.klipsch.com/kg-5-5#second Quote Link to comment Share on other sites More sharing options...
silversport Posted May 14, 2016 Share Posted May 14, 2016 (edited) when I had KG 5.5s I used several different power sources but the Panasonic digital receiver had 100wpc, Outlaw Audio RR2150 at 100wpc and I also used a Nakamichi STASIS with 45wpc...those speakers can bring it but I never had to use all that power...they are quite efficient...I didn't settle on the Panasonic because of the watts per channel but just because I was using mine as a smaller, 3.0 home theater set up... In my 3.0 (L-C-R) set up, those KG 5.5s provided plenty of bass for movie watching... When listening to just music in my preferred Stereo (rather than multi channel) the Panny could use a Dual Amp set up which allowed the multi channel amps to boost power to the amp used for Stereo and provide better sound...

Fjd Posted May 14, 2016 Share Posted May 14, 2016 I couldn't find the specs on the Klipsch site; however, from the specs I found below showing 98dB sensitivity, 75 watts should allow you to hit slightly over 116 dB peaks in the music easily at one meter from the speakers. When considering the listening distance, while there is not a drop in sound per meter, the listener will experience a sound level drop of 6 dB per doubling of distance. The wildcard that I’m not familiar with is related to the impedance curve of the speaker. For example, the KG 5.5 uses a parallel speaker connection for the two woofers. When speakers are connected in parallel, the impedance is reduced, which means that for the same amplifier output voltage, the current demand on the amplifier will be increased. As an example, if you have two 4 ohm woofers connected in parallel, the total impedance is 4/2 or 2 ohms. The two-way KG Series KG 5.5 floor-standing loudspeaker was first introduced in 1994 and manufactured by Klipsch until 1997. Specifications: FREQUENCY RESPONSE 34Hz-20kHz(+-)3dB POWER HANDLING 100 watts maximum continuous (500 watts peak) SENSITIVITY 98dB @ 1watt/1meter NOMINAL IMPEDANCE 8 ohms TWEETER K-85-K 1″ (2.54cm) Polymer dome compression driver HIGH FREQUENCY HORN 90(o)x60(o) Tractrix® Horn WOOFER Two K-1023-K 10″ (25.4cm) Injected Carbon Graphite cones ENCLOSURE MATERIAL Medium density fiberboard construction (MDF) ENCLOSURE TYPE Bass reflex via front-mounted port DIMENSIONS 37.5″ (95.3cm) x 12.25″ (31.1cm) x 17.5″ (44.5cm) WEIGHT 69 lbs. (31.3kg) FINISHES Whitewash, Lt. Oak, Med. Oak, Cherry, Walnut, Black Satin veneers, Black vinyl BUILT FROM 1994 BUILT UNTIL 1997 Well not a fully horn loaded system they are still very efficient. Anything above 35 watts solid state will drive them as high as you wish without distortion. Relax and use what you've got for awhile and then, if yo need to, make move from there. Thebes brings up an excellent point, as long as the impedance of the KG 5.5 doesn't dip too low for the amplifier, the 35 watts should allow him to experience the true feeling of the 109 dB peaks that a grand piano crescendo will hit during a concert. Sure is a nice advantage when using a high efficiency speaker given that every doubling of power is another +3dB of loudness. Those guys with the low efficiency speakers (e.g., 86 dB) sure have it tough when it comes to watts as they would need 256 watts for the same 109 dB peak. 1 w = 86 dB 2 w = 89 dB 4 w = 92 dB 8 w = 95 dB 16 w = 98 dB 32 w = 101 dB 64 w = 104 dB 128 w = 107 dB 256 w = 110 dB Now with 98 dB sensitivity of the KG5.5 1 w = 98 dB 2 w = 101 dB 4 w = 104 dB 8 w = 107 dB 16 w = 110 dB 32 w = 113 dB 64 w = 116 dB 128 w = 119 dB 256 w = 122 dB 1 Quote Link to comment Share on other sites More sharing options...
MORE KLIPSCH PLEASE Posted May 14, 2016 Share Posted May 14, 2016 I've always preferred to have a little too much power versus not quite enough. Agree..... As Bob Carver would say...... "you never have too much power" Just saying .... MKP :-) 1 Quote Link to comment Share on other sites More sharing options...
Zappa Freak Posted May 16, 2016 Author Share Posted May 16, 2016 thx guys settled on an Onkyo TX - DS787 6.1 will set it up as a two channel unit for my TT...................... Quote Link to comment Share on other sites More sharing options...
