Bloody tweeters!

What's Hot

Who started this stupid idea in bass amps?

I've got a potential new bass amp on loan/approval, and I've just gone and blown the tweeter... sort-of my fault since I was putting fuzz bass through it, but surely the designers should have figured out that someone might do that, and limit the possible power to it enough to stop it blowing that easily. It's not switchable on this amp, but I thought that turning down the top-end so the sound wasn't obviously fizzy would be enough to be safe - wrong.

I admit I do actually sometimes like a bit more high-end than a single 15 or a couple of 10s will give, but there's no need for the extreme HF response of a full-on tweeter - a small-diameter driver or a 'whizzer' cone on the main one would be plenty. It's *bass* amplification, not a PA...

    Yup. Tweeters in bass cabs can get in the bin.

    I've disconnected it for now, which has stopped the nasty scratchy distorted noise it's making - and no, that isn't the fuzz pedal , that's with a clean sound. If I buy the amp I probably won't bother replacing it unless I come to sell it...

    Blown tweeters are one of the most common problems I come across in bass amps/cabs, but luckily very few people seem to care so it's usually easiest to just ignore it if they've died completely .

    I won’t buy a cab with a tweeter unless there’s a way of tuning it down or off completely.

    Playing fuzz bass through it at high volume for a short time seems to work quite well :).

    You will insist on buying this stuff with complicated electronics in it ;)

    lol

    The only reason I want it is because it's a 500W combo I can carry on my shoulder... and because it's red :).

    Please explain why anyone would need a tweeter on a bass amp. The frequencies are actually low to very low.....

    It actually does bring out a bit of extra definition and clarity which can be useful. But it doesn't have to be all the way up into the 10KHz+ region which is what you need a tweeter for, a decent small-cone driver is fine. I had a nice little Trace Elliot 2x10"+2x5" cab a long time ago which was perfect... plenty of top-end without fizz, and it sounded fine with fuzz as well :).

    My Ampeg PF115 has a tweeter that was noisy, I thought it might be the crossover unit but I never bothered to investigate. I just turned it off and the cab sounds fine without it.

    The fundamentals are low, but the harmonics can be much higher - also some people like the clank of the string against fret noise

    I like the clank of string against frets. More noticeable with a maple board too.

    I must admit, in the right context I do too...

    Typically in a mix, I'll be looking for harmonics and definition somewhere between 2-5K on the bass, exactly where and how much just depends on the song. But if it's a very busy heavier song, then quite often the top end definition on the bass will be *above* all but the highest fizzy air of distorted guitar. Tweeters, though, are totally unnecessary for that. Usually, even with an ampeg 1x15 (my preferred when miking) I'll low pass down to just above the upper end definition to get rid of pointless stuff.

    Couldn't agree more: totally pointless.

    I remember a very painful and circular "discussion" with a customer along the lines:


    Me: You've blown the tweeter in your bass amp.

    Customer: Why's that then?

    Me: Do you use fuzz?

    Customer: Yes.

    Me: That will be why you've blown the tweeter.

    Customer: Oh, but I like the sound of fuzz with bass.

    Me: Well it's probably better not to replace the tweeter.

    Customer: But it doesn't as good without the tweeter.

    (Actually I found this hard to believe, but there you go).

    Me: But you'll blow  the tweeter again if you use fuzz.

    Customer: Oh, but I like the sound of fuzz with bass.

    Me: Well it's probably better not to replace the tweeter. 

    Customer: But it doesn't as good without the tweeter.

    and so on......

    In most circumstances you don't really hear the fundamental but the harmonics, so you don't really need very low frequency reproduction either.

    That’s true - but our ears often put the various bits of “evidence” together to create the fundamental in what we hear

    To be fair, I think the tweeter does add something good with fuzz, if you want that sort of ‘synthy’ fuzz sound... but you only need a *tiny* amount of it. So putting a big resistor in series will probably help, if there’s no attenuator built-in.

    But if the options are full tweeter or no tweeter, no tweeter wins every time.

    And I still think it’s better done with something like a 5” cone speaker anyway.
