Knuck, welcome, and don't be concerned about bi-wiring(aka "buy-wiring"). Some speakers have two sets of input terminals, but this is essentially a concession to a misguided fashion. The only significant electrical difference is that using two wires is equivalent to using one wire three gauge numbers lower(e.g. two 16ga biwires equal a single 13ga wire). There's no special separation of signals that takes place; both wires coming into the speaker, if bi-wired, carry full-frequency. The separation takes place in the crossover inside the speaker and it doesn't matter how many wires there are before the crossover.
The HK receivers would be fine, and there's no need to "match" receivers and speakers, but I'd suggest that you also give strong consideration to a receiver which has automatic room and speaker equalization(not just level calibration), such as the Yamaha 1400.
