Right, so I've had this old Peavey Century 200 (4ohm) head sitting around for AGES, finally the other day I decided to give it some company by purchasing a TC Electronic 2x10 (8ohm) cab.
Because the Peavy is 6,000 years old and the cab is pretty modern, they both have different connection plugs (Peavey is standard 6.5mm jack output while the cab is Speakon input).
So I buy the right cable to connect them, turn on the power and everything seems ok. A short while later however I start getting this almighty thudding sound, like a heartbeat on steroids. It doesn't matter which dials I turn on the amp, even with everything dialled off, I still get the thudding sound. I look at the speakers and they're about to jump out of the cab.
Here's the weird part though, when I tilt the head 45 degrees, the thudding stops completely and everything functions as it should. I should also mention there is quite a lot of heat, I'm sensing this is a bad thing as I've never had an amp kick out so much heat.
I'm hoping someone can help me understand what's going on before I ultimately burn down my house.

Seems I may have overpriced the cab a bit, so will take £600
Both with covers, both decent condition, a few scratches on each and one small break in the tolex on the bottom of the cab, but all working perfectly.
Great little lightweight rig, have gigged it in plenty of medium rooms with no trouble. Just about light enough that I’ve trollied it on the tube to a few gigs.
Can’t really justify having two bass amps at the moment, hence the sale.
Would rather sell together and will chuck in a decent speakon cable and kettle lead. Otherwise £250 for the head and £375 for the cab.
So I just made a sort of "4x 10" + high frequency tweeter horn" faux cab sim (not completely accurate, really just set to my personal liking, but perhaps not all that different from a 4x 10" cab with its high frequency tweeter attenuated some) on my Zoom MS-70CDR by stacking 5 of the 2 band parametric bass equalizers, "BassParaEQ", and thought I'd share it in case someone else could have use of this experiment of mine.
Of course this could be made with any 10 band parametric equalizer, and one could eventual skip the boost of the 400Hz and 800Hz bands, if they only got 8 bands available, eventual the 50Hz and 120Hz bands as well, in case they only got 6 bands at their disposal, also technically one might be able to get away with skipping the 20kHz band too, as the signal from a bass won't produce much frequency content above 10kHz anyway, and finally one might want to set the 400Hz and 800Hz bands differently, slightly boosting or cutting them according to the preferred character of the simulated cab.
So here's how I have the EQ's set, listed in the order of the signal flow:
Freq: 50Hz Q: 1 Boost/Cut: + 1dB
Freq: 120Hz Q: 1 Boost/Cut: + 2dB
Freq: 400Hz Q: 4 Boost/Cut: + 2dB
Freq: 800Hz Q: 2 Boost/Cut: + 2dB
Freq: 1.6kHz Q: 2 Boost/Cut: - 1dB
Freq: 2kHz Q: 4 Boost/Cut: + 1dB
Freq: 4.5kHz Q: 4 Boost/Cut: - 1dB
Freq: 6.3kHz Q: 4 Boost/Cut: - 1dB
Freq: 10kHz Q: 1 Boost/Cut: - 20dB
Freq: 20kHz Q: 1 Boost/Cut: - 20dB
Is a cheap, lightweight, minimum 200W, powered, full range, flat response cab, with a flat response at max. 50Hz, and ideally with some kind of control over the high frequency tweeter as well, too much to ask for?
I would think yes, by far most likely, but I am open for suggestions of something that at least somewhat approximates that.
