Unfortunately i've reached the end of my lectronic talents, which is poor to start with, so that went over my head

Decided to pull the whole PCB out and check all the solder joints but nothing seems amiss. Looking like a tech problem, and since i cant take it to my local tech, its back in the cupboard for this combo.

If in doubt -

Yup, that white gunk looks messy - i'll give it a wiggle

There doesnt seem to be any problem with TR5 that i can see Its quite a large photo, but it seems you have to click on it a few times to get a big picture

I've done an equal pressure test of cones and they're fine. I dont have a spare amp, to try that tone test

Thanks stub - i'll pull the amp out tomorrow and check that pesky TR5 If it needs a bolb , i'll sort it

Just as a guess, i reseated the drivers, equal torquing down , in case the basket was slightly warped due to uneven mounting, but that changed nothing. I'm beginning to wonder if its the amp

The crossover is disabled as the tweeter is just a hissy pile of poo. I dont use the sub-octave, so its permanently switched out ... same with the compressor. I dont know what the letters mean any other ideas Stub ?

Recording - just using open E. Bass EQ rolled off completely. Sounds like i;m really attacking the string but it was just a normal bedroom level pluck Voice 001.mp3

Oh boy. Failure to sort the problem. Now with Beymas fitted, still getting this low volume buzzing ( like a delicate farting i suppose ) nothing like what i thought a speaker farting would sound like Its from both drivers, and it happens at any volume, input gain at low medium or high, bass eq rolled off completely, varying the main volume , varying eq , changing cables. I'm stumped right now

Thats not what you asked. See your own post

Its possible that he also sells concrete paving

It'll only take me 8 years to save the dosh instead of 10 years

I love the tone on that, Frank

But what if the seller doesn't want to be bought.?

Free postage should swing it.

Ditto Hoping its been sorted

The dust build up isnt huge, judging by what i cleaned off the heatsinks. I could leave it for a couple of years and clean it out manually

Thanks B. I've been extending the ports today, from 10cm to 16.5 cm so i will cut some off

Cheers - yes, i did use software, but i just wanted to be sure, as i'm not that good with these software progs I used ajvented, as WinISD seems too complicated https://www.ajdesigner.com/speaker/ajvented.php If you look to the right of parameters, you will see alignment SBB4, QB3 and SC4 I tried each one and they give different port lengths depending on what i want, but i dont know what those alignments mean in the great scheme of things

@Bill Fitzmaurice Bill, what are the symptoms of a 4" diameter 4" long port that could be either too short or too long ? Currently, the new ports are here, but until the foam seal has arrivied, i'm not going to fit the drivers. When the cab is assembled, i'd like to know what to listen out for. E.G. if the port is too short, i will hear xxxx and if the port is too long, i will hear xxxx Edit I have some 4" ducting here if the ports need more length
