802 Nautilus and Ohms

[mati1979]

Hi, i have a 802N
Today, i check today a Ohms with my tester
and i see 4.9 ohms
this is normal ?
In a manual i see: 8 ohms

An ohmeter is not a suitable tool as you need to measure the impedance vs. frequency and not the DC resistance, as you have. That said, the measurement seems normal for DC resistance of an 8 ohm speaker.

If you do not have the ability to measure AC impedance vs. frequency, you can search to find a review measurement. Here's one for similar B&Ws: B&W 802D loudspeaker Measurements | Stereophile.com

Thank you Kal

The 802 mid driver has always presented a very difficult load so we always vertically biamped them on the salesfloor and tried to implore customers to do likewise.
