Obviously an unwanted expense but a Furman power conditioner might help?

[JTUK]

I couldn't have this uncertainty, it would drive me nuts.

My thinking would be clean supply issues... but you shut it down if you peak it..??

I don't care if it is a design 'feature' or whatever, if it happens more than once, it would not be good enough. IMO.

Kinda defeats the point of a compact setup. I have to say, having had a Furman conditioner in my rack for some time, they really don't do a lot. I just like the light. The UK power supply is clean enough to do without the Furman... it's when you are running things off generators that your power conditioners come into play.

Have you spoken to MarkBass directly? I have told this to another user and he found that they provide great customer service. I would try that avenue first then look at other alternatives.

@EBS - I don't it has nothing to do with small amps, look at trace elliot for example, they are big strong and fail like every other, these are machines and their components don't last forever.

Same way a car in the 60's would drive for 30 years fine and nowadays a brand new car will strugle to reach the 10 year mark.

I'm going to call the UK rep.

Spoke to Alberto at Proel UK. He said try your cabs, as a blown horn may cause the impedance to drop. Bugger me, the horn in each cab has blown! Thanks to my lack of hearing properly, I never noticed. Two replacements on the way.

[davidmpires]

I'd still speak to them directly. They may offer you more than what Proel is offering.

So in this case the amp effectively did the right thing by protecting itself from an impedance change (when the tweeter blew).

I'd say having the cabs fail and the amp not dying would be a good thing. If it protected itself by turning itself off its doubly good IMO, its giving you a very big clue that something has gone wrong, and stopped itself being toasted at the same time.

I remember a couple of cases a fair few years ago now where PA horns blowing took out the amps driving them.

Far from a reason to doubt these 'little' heads, I'd say it was a damned good reason to buy one (casually aimed at Monsieur EBSFreak )

[Pete Academy]

Alberto rang me back and asked me to check if the crossovers are intact in each cab. They are. He's sending a couple of horn diaphragms.

What's bothering me is why and how the horns blew in the first place. We are not a loud band on stage, so I don't push the cabs very hard.

Really struggling to read your posts Pete, something to do with your avatar?

[lonestar]

liking the new look though.
Is she one of your new backing singers ?

No way should she be backing you! Get her up front and enjoy the show ... Ooops. Gig, I mean gig

I think a Burberry baseball cap would complete the image.

I'd say that's a good reason to doubt - imagine you are on tour where spares aren't readily available. Surely you want an amp that can handle the impedance mismatch of blown tweeters to get you through the gigs? And Pete doesn't even play loud... what happens if you are in a band that does? Weak argument - the amp may protect itself which is great - but it could leave you in a right crappy situation.

No chance. If the amp is working and the cab isn't, just stick it through the PA via DI and use the monitoring system to hear yourself until you can get a new cab.

I'd rather one thing blew and the other protected itself. Less money for you to shell out when replacing broken gear!

and Ashdown amps catch fire. I'm not hating on these amps and I'm certainly not doubting that the concept is great... it is. Obviously things fail from time to time. I just hope that Pete gets sorted out.

Two horns?! Woah.

[stingrayPete1977]

EBS_freak are you dissing little heads again? How is your backache! My 600w into 4ohms is a real struggle to lift with it weighing less than a bag of sugar And I think your spitfire through it at The Gate was your best ever sound too,IMO.

Sell the Markbass and buy Genz-Benz you know it makes sense

Pete,
I don't know about your cabs but that pic has blown my horn

Not dissing little heads... just saying that the inability to handle two cabs with blown horns is a bit iffy.

PS I didn't play the Spitfire through it though.... that was the Rumour! And I still prefer it through the EBS I'm afraid.

must say pete your avatar has reall brightened my evening who is she?
sorry to derail i just wish EBS would make a little head, with two channels

[stingrayPete1977]

Oh yeah, Lights!
When the crossovers are not switching in the horns then surely thats as low as impeadance would get which would be the same as the blown open circuit horns? Then impeadance would rise as and when they cut in and out.Or is it the other way round?Or is the Markbass just very sensitive to the load changing? I have confused myself now..........
