Clipping

#41

How can you possibly say this as fact? You and nobody else here knows what the cause is because the OP has not followed up with any additional troubleshooting information.

It's POSSIBLE that there is a problem with the cabinet, but it's MUCH more likely that the problem is with the bass, or with an amp that's grossly underpowered for what the OP is expecting and what he is hearing is gross clipping into a reactive load. It's also possible that he is clipping the preamp on his amps if the bass is really hot and the amp's gain is set too high for the bass.

and still it's due to the cab
if the bass it's hot, and the head spins, the cab, even if correctly workin' (so... unbroken) it's possibly too weak, or simply "tuned like that" to the point of givin' a harsh sound back on certain frets.

of course I'm assumin' the bass to be set right-neither chimes nor cuckoo placed on the head ca va sans dire mon ami;)

Cheers,
Wallace

I think there is an issue of language translation here.

If by “language translation”, you mean “common sense”, I think I have to agree. Andy, I have to again give you props for providing great technical support, and its free here!

I find the internet to be a vast universe of.....stuff....not necessarily knowledge. But when someone with credentials such as yourself willingly provides reliable expert guidance at no cost, I for one perk up and listen!

Dan - it's not the speaker that's clipping or distorting. The amps will clip and distort when driven beyond their capabilities and the speaker is simply reproducing the distortion that the amps are generating. The lower the frequency being reproduced, the more power it requires.

You will need to turn the amp down until the distortion disappears or use a more powerful amp

It's not that it's not a lot of power, it's not enough power for the volume that it's being played at.

Dan, this is the info you need.

If you're new to TB, you may not realize that @agedhorse is a highly respected amp designer. When he gives you advice of this type, you should assume that your question has been answered accurately.

Bravo. Start every new situation with an open mind and “keep your listening ears on”. Everyone here has a unique and valuable opportunity to learn some incredibly useful information and get top shelf answers to your technical questions at no cost. Or conversely, you can ignore true experts’ advice, and believe any random poster wandering through the internet void with misinformation. Proper credentials are of tremendous importance, especially now in the age of the internet. People should evaluate sources of information for reliability, and should maintain an inquisitive mind, and a healthy dose of skepticism.

If you have access to a small mixer with a headphone output, you could use the di output on the Trace to drive the mixer and listen to the signal on headphones. If you still hear the "clipping," your problem is not in the power amp section or the cabinet.

of course its not the cab LOL

well atleast my 810 doesnt have these problems with " underpowered" heads

maybe the OP changed his battery and switched to a different cord
Click to expand...
Sure no 8x10" should show any défaillance like that

But remember the OP's only talkin' about a 2x10"

An'I happened to have a few drivers in traditional 4x10" powerhouses stripped down just by playin' a plain an'simple standard tunin' passive p bass

Ok: disclaimer time here

Never read your profession before, so I should have payed attention

Why?

'cause I honestly dissed the cab, comin' from a few bad experiences with some of'em... not now, not anymore... but I spent nearly twenty years of my live life with a downtuned underground thrashmetal band, nothin' special lettin' alone havin' the opportunity to try and test lot of gear thru the years

Pushin' cabs with overdriven active ceramics and onboard preamp (in the input) and outboard preamp (in the pedalboard, in the fx loop) and all these stages within amp compression, shape and eq, sure can drive speakers to their very limit... but only a few failed... of course, dependin' on the amplifier, but one of my many commitments is to try and match amp/cab per label/series, so it was disappointin' to meet those discrepancies with expectable perfect pairs

Most noticeable to me (and myself only... so that I ain't preachin':cool:) were a German company, a New Yorker and a Californian: the former and the latter I ain't got no equipment of anymore.

So here's my disclaimer
And my apologies

Never meant to hurt anybody, or to desecrate hollow grounds
Peace

Cheers,
Wallace

OP, your amp is hitting the wall so to speak and as a result, you are hearing distortion. At 12:00 on the dial, you are already hitting the the max your can deliver, numbers on the volume dial mean very little to nothing.
As others have said, you are asking too much from both those heads, they are already giving you all they have.
It's like bringing a sproke to a knife fight!
Buy a more powerful amp to get the volume you desire.
