I just found out that the SWR Golliath Sr. 610 is a 4 ohm cab...How do they do that? A 4 ohm cab means, most likely, that there is 2 8 ohm loads in parallel. So then you either 2 sets of 3 speakers @ 8 ohms (?), or 4 speakers @ 8 ohms and 2 speakers @ 8 ohms. If it is the second combination then power is mismatched, meaning that not all 6 drivers are the same impedance which means that they are not all pulling the same amount of power. The only way I can figure you can wire 6 drivers is by either having all 6 @ 4 ohms which will end up with a 6 ohm load, or all 8 ohm drivers with a 12 ohm load. Of course, with most amps able to handle 4 or 8 ohm loads the 6 ohm cab would be more desireable. If anybody has any insight as to how a 610 cab @ 4 ohms is accomplished please let me know...it's driving me nuts! Thanx.
