Agreed it is easier to do with a signal an octave lower than the speaker was designed to handle. Maybe when TC made the RH750 and matching cab they thought that they might be used together? As I said, all of what you are saying is true for other amps and other speakers, and I have no questions on that. The RH750 has Active power management (that it is often slagged off for) which means it will never produce more than 35V (see attached) without clipping (as it peaks), and it has (according to talk bass where it was tested - I have no other sources) a 2nd order HPF starting at 70Hz at 12dB/Octave. It is incapable of producing a 'signal an octave lower than the speaker was designed to handle' as literally the speaker was designed to handle the output of the RH750. Add as a caveat to that, the HPF is only in the power amp, so if you take the output from the DI or the preamp out, and put that through an amp, then yes you really can damage it. I don't see there is much point adding anything else to this, although seeing as the TC RH amps are very common and most of the time paired with the RH cabs, I am obviously happy to see links to all the 'my amp broke my speaker' threads that must exit. To the OP, don't put any bass into any speaker, as apparently it is far too risky as none of them can handle it. tc450 stats.pdf

Yes, I just checked, turned out the speaker is an 8 ohm, I was thinking it was a 4. So I doubt it can get over 200w. Sure, you can't guarantee anything, maybe there is a manufacturing defect, or maybe you are going to find its resonant frequency and leave it running for a few hours. If you are determined to do a thing you can probably do it. But as I said, it is not something I would worry about at all if it was equipment I had paid for. But you pays your money, you takes your choice.

you wouldn't need new pickups (and I assume like the other neck thru epiphones, they are gibson pickups), just take the preamp out, take the battery out, and wire the output from the blend to the output socket.

Just think how bad you would feel if someone did buy it?

Exactly my point

Agreed, but that is just common sense, just because someone puts a sale tag on something, look around to see if it is cheaper. Generally though if you wanted it before the sale, you know how much it cost

OK, so then for the OP it is a data point. I would not think twice about doing it, you would, so it is up to them what they do. The TC power amp has the power management to prevent the power stage clipping, which is what all the fuss and anger about their power ratings comes from.

Some, not all. A lot of shops would be better to not do it, but it depends on your market. That ab600 I bought is a b stock, it has been reduced since their sale last month and I have been interested in it since then. I kept going back and thinking about it, but I didn't buy it (its a lockdown, don't get to use an amp but it is a good deal). But they put a 10% on that, and I did buy it. So in this case it made a sale where one wasn't.

Symphony No 6, Beethoven. (the pastoral one).

It wasn't just a few years ago, as you can see, these things carry on. People seem to get very upset about other people liking any of the RH heads. Which I do!

no offence taken but the output rating of the RH750 is, as people will spout with an almost religious passion if you dare to like them, less than 300W, so into a 400W speaker you should be able to run it flat out at any frequency for hours on end (which wouldn't happen with playing) without it going close to the Kenny Loggins zone.

I don't think so. If there is something you wanted (like I did) and now that same thing is now 10% cheaper, that is a worthwhile deal. As long as it was something you wanted in the first place.

Yeh, I have been trying to justify it for ages, and assumed it would have gone but then realised there were two. So now there are none. The 10% was just enough to push it over the edge, on the hope that one day it can get used Oh don't get me started on that, now my amp is actually slightly over the rating of my speakers so I am thinking, hmm.. do I need something else!

No, audiences are just wondering why the guy with the big guitar isn't doing a solo. Excessive distortion on "Abba-doesn't your mother know", Brown eyed girl (in the middle), subtler distortion in a few other things.

That is sort of my fear. I don't want to die, obvs, and if I do die I don't want the extended tube down my throat drawn out dying thing, but much more than that, I don't want to get it and live with the long tail version. If I can't concentrate and I can't move around without trouble, then I am not going to be able to be working. Its a small risk, but my markov decision process tells me that it really isn't worth the effort of playing mustang sally in a room with a bunch of people

PMT have 10% off, so I picked up their remaining B-Stock ABM600 Evo-IV, which was £389, so with the 10% off it was pretty well half price. Just what I need in a lockdown, a 600W amp

From what I see on the net the power amp on the RH750 has a HPF (not the preamp), to keep the lows out. As the RH750 produces less power than the RS212 speakers rating, I am not sure it would be possible to damage it. Not something I would worry about. However, if the sound made your ears funny, that is certianly something to worry about.

I know that, if you are going against the power limit it will compress. I just wondered what 'artificial' compression was. I also gig with a 100W Ashdown CTM100. Obviously when I am gigging with that it is also compressed as it is running quite hard, in fact more so because I am running it harder. Is that 'natural' compression? Its just the terms that I was wondering about, not what compression was.

That's why it doesn't rattle

Maybe I just don't know what 'artificial compression' is, but it certainly never caused me an issue, maybe that is why I don't mind it. The knobs were bad (although the replacements they sent me haven't cracked - maybe different plastic). Certainly never had a issue with it being underpowered too, and the group is too loud anyway (although we only play pubs and clubs), which is a concern I have with the CTM.

Yes. Obviously one persons ideal tone is anothers nightmare but I trust the TC450, it has never let me down, it weighs very little and fits in a bag great, its not delicate and I have never not been able to get a good sound for it in any given circumstance. And it has a full time tuning light on the front that the guitarist can look at to reming him of what key he is supposed to be in.

I was thinkin this. I have done.. from my reckoning, 130+ gigs with my 450 and I am not really thinking of changing it any time soon. Again, mine has either been with the RS cabs (2 x 112) or the BC cab. Probably done about 10 gigs with my Ashdown CTM100, probably a better tone overall but loses on the Clean volume / weight / convenience scale.

We do indeed, focusing on just one thing. Congrats to the British/Swedish astrozenica for funding the devlopment of the vaccine developed by scientists and researchers from many countries in Europe and beyond, using techniques developed around the world. Its amazing how much science you can do when you can remove borders.

hahaha - an email to my MP, that would be a fine idea. Or I could just write it on some toilet paper, at least that would be a bit more constructive. Seriously, my MP is just flown in to make up the numbers, and is of absolutely no use whatsoever. The only time he is in the town is for photo ops.
