impendence question

[bigdolf]

it says that the hb-1 mk2, and the hc-1mk2 are 8ohms.....then when you go into the the owners manual pdf the hb1 is stated nominal 6, minimum 4, and the hc1 is nominal 12 min 8....could someone clarify this please

Hi bigdolf,

While the minimum/nominal impedance is as stated in the owner's manual, with all the modern day receivers, we recommend setting the impedance setting to 8 ohms. This will provide as much power as possible to the speakers. The HB-1 MK2 is really not too difficult a load to drive, and these receivers have overload protection circuitry anyway, so it is worthwhile to use that impedance setting.

Sincerely,

just wondering, I got a onkyo nr1007 so it should be fine

[Pete_Hsu]

Absolutely, you will be in good shape with that receiver :)

Pete, since the HC-1 use the same driver as the HB-1 and the HC-1 impedance is double, this indicate the woofers are wired in serie, right?

And since two identical woofers should have double power handling than a single woofer but the HC-1/HB-1 are rated at the same 250 watts power handling, one could assume the limiting factor must be the horn, right?

[Pete_Hsu]

That is correct Deromax, the two woofers are wired in series on the HC-1 MK2. Yes, the tweeter is the limiting factor. That said, the HC-1 MK2 will still have wider dynamic range than the HB-1 MK2 due to use of two woofers.

Sincerely,
