GetYourFunkOut93 Posted August 4, 2012 Posted August 4, 2012 Hi chatters, I have a TC RH750 and am looking for TC RS cabs in the future for my rig. On the back of the head it says its min load is 4ohms. The RS112 RS212 and RS210 cabs are all 8ohms.. But I've seen people with 3 TC cabs stacked to make up their rigs.. But that would not be 4ohms.. It would be lower. Just wanted to know what people think about it. Cheers Quote
charic Posted August 4, 2012 Posted August 4, 2012 The TC head [b]LIES[/b]! People will tell you asap it can't possibly sound good ontop of that... The truth is TC released details later saying the head infact goes down too.... 2.36Ohms! (Or 3 cabs). Cool huh?! Quote
BottomE Posted August 4, 2012 Posted August 4, 2012 I have been looking for a previous thread that explained this to help you out but failed - sorry. I know what you mean though. I have the RS212 and RS210 cabs but was thinking about upgrading the amp to a Shuttle 9 and would need another cab to cope with the additional output. Quote

Ontop of what? And thanks, Bit weird saying it on the head when they could just change it. And looks like my rig is gonna be 3 cabs now then [/font][/color] Quote
mcnach Posted August 4, 2012 Posted August 4, 2012 This question has been asked many times (not a dig at you, I ask questions that have been asked before many times just saying that you can find this info elsewhere from other people more reputable than myself, that's all ) So, yes... find the details on the TC website. But the short answer is: it's ok. Impedance is not a fixed number for all frequencies, so giving one number alone is an exercise on abstraction. An indication. TC knows the behaviour of their amps and of the speaker cabs they use with those amps, so they recommend to treat their "8 ohm" cabs as "8 ohm" cabs when using other amps, but if using TC amps, you can use up to three of them. The amp has a auto-shut down safety mechanism built in, so it's unlikely you'd damage it if you went lower than you should, but yes, 3 TC cabs are ok with TC amps. In fact it was one of their advertising points: "use up to three (TC) cabs for a ridiculously powerful rig", or something along those lines. Mixing brands? Treat the head as a minimum 4ohm and cabs as rated in the back. All TC? Then use the head with up to three "8ohm" cabs Quote

chris_b Posted August 4, 2012 Posted August 4, 2012 The amp is 2.67 min so 3 8 ohm cabs from any manufacturer will be fine. I ran 3 Bergantino cabs with mine and it sounded pretty damn good. Quote

This head can go down to 2.66 ohms with any cabs it would seem. TC even released info to confirm that. Quote
RandomBass Posted August 5, 2012 Posted August 5, 2012 And as we all know the truth that TC amps only put out about three and a half watts, you will need as much speaker area as possible to be heard over a tweeting budgie. Actually, I'm probably just jealous. Quote
