2004年3月10日 · KEF America now sells a replacement tweeter for the C80. The model number is SP1549+ and they told me that it will fit right inwithout modification to the cabinet or crossover. It also can be considered an upgrade as it is supposed to be a little smoother and more extended than the original.

2019年4月28日 · Maybe the new design crossover could mimic something like the KEF Concerto or the Constructor series CS7? The only snag here is, the Concerto and CS7 used the B139/B110/T27 driver compliment, whereas the C80 used the B139/B160/T33 drivers. Not only but also, the drivers in the C80 were all 4 ohms, the B139 itself is the unique SP1212 version.

2010年11月27日 · The C80 were actually more expensive than the cheapest Reference 102 IIRC from my days of selling them retail. The price is fair for a pair in nice shape, the much smaller C60 generally go for over $100 and sometimes up to $200.

2014年12月16日 · The C80 was the second C-Series model to benefit from KEF’s ‘conjugate load’ crossover network design, originally developed for Model 104/2. The net effect on your hi-fi system of replacing a conventional 8 ohm speaker with one which presents a 4 ohm constant resistance is that you can double the sound power output of your existing ...

2007年4月2日 · Kef C-80's Called the seller. Young girl was selling them. She said come over and look and see if these were worth the 20.00. She was only 20 minutes away. Got there and she couldnt get them to work with a Denon DRA-95A AV receiver. I couldnt get any sound either, so I asked her what she would like for them. She said 10.00 for the speakers and ...

2007年12月20日 · True, they were used in some of their complete speaker units i.e. 104 Type II. BTW~Dave at "planet10" seems to know more than most about Kef units. Might be worth an email. No possibility of a photo I suppose? Edit. I've just put "Kef B139 sp1212" into Google and got a reference to another thread in this site. He too had a C80 and they were 4ohm.

2016年11月20日 · Anyone have experience running Yamaha M-70 or M-80 into 4 Ohm Speakers? I have a pair of KEF C80's that need a lot of power and looking at maybe a Yamaha to power them. Plan was to use my existing H/K 630 Twin Receiver as a Pre-Amp. Thoughts on how they handle 4 Ohm speakers and if this is a...

2012年6月11日 · The Adcom has a bridge toggle switch, so out of newbie curiosity I wondered how to connect it to one speaker (KEF C80, 4oms). I do know red is (+), and (-) is black. As I keep looking I see that I need to be careful not to do something dump that could ruin things.

2022年9月10日 · Just got a pair of KEF Concerto. I have purchased new crossovers, so I took the drivers out. I have two questions, and I will appreciate your help: 1. The mid drivers don't have any "kef" logo / mark on them. Are they the original ones? I have attached a picture 2.
