Boston Acoustic VRM series 4 ohm

[robiner]

Hi,

Wanted to know if anybody out there own a VRM-90 boston acoustic floor standing speaker with an impedance of 4ohm.

I just bought a used VRM-90 speaker but it did not come with a manual. So i check on boston web site and i found that it is rated 8ohm but the sticker on the back says 4ohm for me.

I wonder when boston changed it or is there like different version?

Thanks in Advance for any info.
