I have occupied myself intensively with the box and felt the following things are important:
Use 1 subwoofer crossover frequency 90 Hz with me
2. Clean installation, on the right stands (Phonosophie LS 3 or similar), close to the wall to taste
3. Use bi-wiring, who does not do away at least 50% of the potential of the Box
4. Matching electronics, which is a broad term - a little analytical sounding amplifier matches the restrained character of the box (see below)
5. give enough break-in period (within 1 week with daily 3-5 hours of play lives on the box right)
Close 6) Bass tubes supplied by foams
My amp is a NAD T 758. My Tuning KEF Q300 / NAD:
capped a) COAX digital outputs on NAD consistent with 75 Ohm end pieces
b) RCA connectors on your NAD consistently capped RCA covers
c) extra-thick power cord
d) INAKUSTIK LS-1102 running speaker cable with low-mass connectors of ViaBlue between NAD and KEF
e) INAKUSTIK ON / OFF 202 coax cable between NAD and digital source (CD or digital sound card)
f) Phonosophie HiFi rack for the NAD
Absolutely fantastic !!!
