Dear KEF owners,
I received my first pair of KEF speakers today, the iQ1 set, which I plan to use as rear surround speakers. I also received the iQ2c center speaker. I have all wired up and did audition the iQ1s as front speakers before I moved them to the back. I believe that I have them wired correctly-please read on. I first connected each speaker(iQ1) with 14 gage speaker wire and did NOT connect the bi wire channel device thing at the back(the thing that one uses if one chooses to bi-wire or bi-amp the speakers). The speakers sounded a little off. So I then connected the channel devices at the rear of each speaker, along with the speaker cable, into the slots, + and - accordingly. The sound was much better thereafter. I conclude that one must, in fact, connect these little pieces along with the speaker wire, into the slot, even though one does not bi-wire or bi-amp the speakers at this time. Is this correct? Page 3 of the manual is a bit lacking in depth. I connected the channel device to the top (solely) posts alone, then to the respective bottom post along with the speaker wire for that polarity.
Could someone explain the concept of bi-wiring or bi-amping and explain why these little channels must remain connected, if this is correct?
I believe that my KEFs produce sound that is a bit on the high frequency side, a bit more treble than bass; I do like the sound, although it is a bit different from my front main speakers, Infinity SM100 ported floor standing speakers of back porting and sensitivity 98 db, 8 ohm imped., with frequency response for those from 35 Hz-27kHz, whilst the iQ1 offers 50Hz-40Khz.
Further, the crossover freq. of my Infinitys are 2500 Hz and the KEFs offered 2800 Hz; I felt that this closeness in crossovers was a good point, do you agree(i.e., desired when choosing speakers, to have very similar crossover frequencies)? (I also use a Marantz 110 Watt SR7002 receiver, 14 gage copper wire to KEHs with black and red jackets over each conductor set, as side surrounds I use Infinity Sterling (sealed) SS2001 with crossover freq 4500 Hz and these are 6 ohm speakers, this pair may be my "weak link", as the others are 8 ohm speakers and better quality and are ported).
I was quite pleased with the packaging of these speakers - they each had a cardboard hand-made cutout to protect the face(with Scotch tape and obviously hand made, nice to see that they care), and these plastic bendable inserts that protected the fronts from scratching by the grilles, a black plastic piece of meshlike fabric. Styrofoam also completely engulfed each speaker entirely, with bags over each speaker. Nicely packed.
Finally, the small black styrofoam port plugs - why would one use these? I do not understand the diagram from KEF on a handout, showing these plugs inserted if a graph of the crossover frequency has a spike just after 2 Hx - how would one know this value and that these plugs are needed ? Very confusing.
Thanks for any help on the above - I did search for answers first,
Thank you, Debra
