Sod the Kefs is that Bruce Willis in the photo?
I think they were 12" not 15". Still nice though.I've never seen KEF 105s with the top and mid head covered. Photos always show only the bass section covered. They don't look attractive.
I had the bigger KEF 107s for several year and these were better looking, being taller but slimmer as its twin 10" drivers were installed lotally inside the bass enclosure with a port just in front to the top and mid head. The bass enclosure was veneered all round as no drivers were visible. The top and mid head did have a cover though rather smaller than the 105 as the bass enclosure was that much narrower. The 105 had a single 15" bass driver. Both the 105 and 107 were rare sights in the UK even when being built - most found their way across the Atlantic. Happy days - great speakers - Peter
Fairly flat response and ok it does start to drop a bit from 10k but personal view is whilst a supertweeter might add a bit of gloss up top actually blending it to keep the response flat is another matter.Original 105s. A great speaker thar does a lot right.
I am still of the mind that a supertweeter plonked on top of these could be end game for some.
Yes, you're quite right - 12" bass driver. Enclosures still pretty wide being 415 x 455 on plan. Ugly beasts but sounded pretty good!I think they were 12" not 15". Still nice though.
Uzzy you are definitely thinking of the 107- it is a 4 ohm resistive load, the 105 is 8 ohms and relatively benign, but very inefficient- so your big amp rule still applies.Fairly flat response and ok it does start to drop a bit from 10k but personal view is whilst a supertweeter might add a bit of gloss up top actually blending it to keep the response flat is another matter.
Personal view is it is a brilliant loudspeaker but it is very ineficent so you need a good 100 watt plus amp and it is a resistive 4ohm load so whilst on paper most amps should find it an easy impedance load my experience with the 104/2 would suggest an amp capable of delivering into a sub 4 ohm load makes a lot of sense. (Pal of mine with the 104/2 kept throwing the thermal trip on his 100 watt amp and we tried a few and he ended up with a Meridian 507).
When I had my 107s, I was told that they needed "high current" amps. At the time this rather went over my head and I thought my AVI S2000 MM monobloc amps were amply powerful enough. After selling all that gear, I wonder now if I got the best from those excellent speakers. Were they let down by AVI amplification?Uzzy you are definitely thinking of the 107- it is a 4 ohm resistive load, the 105 is 8 ohms and relatively benign, but very inefficient- so your big amp rule still applies.
You are very right - the later 105 either the 2s or 3s were a 4 ohm load.Uzzy you are definitely thinking of the 107- it is a 4 ohm resistive load, the 105 is 8 ohms and relatively benign, but very inefficient- so your big amp rule still applies.
Their weakest point is the B110 midrange unit IMHO. No amount of 'active' will get round its limitations. On the other hand my pair showed such fantastic bass to midrange integration I can't imagine active improving on it, it was totally seamless, quite an achievement. So I'd not venture down the active route in a hurry myself, but YMMV.Wonder what they would sound like if you made them active ? Just saying asking for a friend .
The KEF B110 is one of the most highly regarded drivers of all time. It was the basis of the BBC LS3/5A that is still, after several decades highly regarded and still in production by a mumber of manufacturers. Other BBC designes also featured this driver.Their weakest point is the B110 midrange unit IMHO.
