The power rating of a cab doesn't mean much. It is the 'suggested maximum power' using the typical RMS rating.

The TC cabs are 8ohms. That means you will be putting the 8ohm power of either the RH450 (I believe about 280 watts) or the 8ohm power of hte RH750 (probably around 450 watts) into the cab... both well below the suggested power rating of the cab.

Peak power means pretty much nothing. So, either head will be fine with the cab.

is this because the amp have 750 watts on 4 ohm

But to say anything further, I'd need to back myself up with our TE's data, so that's why I'm trying not to say too much right now. Better yet, read it for yourself. Don't need me in the middle mucking things up. :)

So where do we look for this upcoming article and when is it due to be published?

Actually, the confusion with this is that there are many heads that actually can run at 2.67 ohms safely (+ or -, depending on the cabs in question), and basically state that any three 8ohm cabs by any manufacturer are 'fine'. So, it is a bit of a strange thing (i.e., two of anyone elses, but three of ours, even though they state their cabs nominal impedance is 8ohms).

I don't think it's reasonable to apply other products' behaviors/attributes to TC's without specific reliable data to back it up. They make it very very clear they only support a third cabinet when you're dealing with their RS cabs. Otherwise, stick with the 4 ohm rule. It's just not that hard.

My guess is, this will continue to confuse customers as it has since the introduction of the RH450.

Only if they don't follow TC's very simple and clearly stated rules, which would just be foolish, and I wouldn't fault the manufacturer for that.

Here it is, directly from the manual... I can't imagine this confusing anyone except someone trying to guess at the reasons why, and then being reckless with their gear based on assumptions. IMHO, never a good idea.

"Cabinets or combinations of cabinets must load the amplifier
with a minimum of 4 Ohm. A maximum of three RS cabinets
can be used or two 8 Ohm cabinets of any other brand."

I got mine yesterday. I have to really commend the customer service offered by Sweetwater. I ordered it online using my cell phone. Later that day, I had a voicemail from my sales rep offering a tracking update and "checking in" to see if I had any questions. This guy has occasionally checked in with me over the past year or so, after my first purchase at Sweetwater, which totalled about $35. Also I had the amp in one business day with free shipping; I would have had it Saturday, but I had it shipped to my office. So, hats off to Sweetwater.

On to the amp. This replaces a Markbass LMII for me, which is a great little amp. The thing I notice most so far is that the RH750 is a chameleon. Everyone on talkbass likes to pidgeon-hole amps, saying it sounds like this or it sounds like that. This make it easier to talk about them. This amp, though, is a good knob-twister. With its four band semiparmetric eq, spectracomp, tube tone, and tweeter tone, this amp has a lot of different sounds. It can get pillowy and round, or tight and crisp. So far, I'm very impressed, but we'll see what I think after a few rehearsals and gigs.

I only have a couple minor issues with it so far. All my cables have neutrik angled ends at one end. Because of the way the sides of the amp overhang the front, plugging the angled end into the amp is awkward at best. Also, it would be really nice if all those lights would go to sleep after you finish knob twisting. Finally, I hear the fan a little more than I did on my LMII.

On the plus side, the tweeter hiss is less significant than on my LMII, and the RH750 is LOUD! All in all, I'm pretty happy so far, but I'm just getting started ith this thing.

Any on you considering buying your 750 from American Musical Supply, let me give you some advice: don't. I've been buying stuff online for about 15 years, and I've never had such a hard time giving someone money before.

To anyone who went from an Rh450 to the 750, is it worth making the move? I don't need the extra power - I'd really only be doing it for the tweetertone knob (to get my high's back.)

Dunno, how important is the TweeterTone to you? :) For me it was, but I can't really gauge how applicable it is to you. I also very much like the quicker access to the SpectraComp, but honestly, that's secondary. I also don't care about extra power.

Good news is, they're very cheap to ship, so just get one on approval from MF or something and compare for yourself.
