I'm thinking of getting this setup and I have a few questions about this.

1) does anyone use this pair? how do you like it?

the next two questions have to do with the wattage and ohms. I have read the newbie info on this info, but it just makes me feel like I belong on the short bus trying to figure it all out.

2) the head is 307W RMS power and the cab is 450W continuous with 8ohms impedance. Will the head power the cab correctly?

3) If I were to add a 210 or a 115 to this later, would the head power t all?

I had an ashdown mag 180 for a while. It was fine, nothing exceptional. I put it up for sale as I found other gear I liked better

I'll take a crack at it. I'm not an expert on electronics and speakers, and there are guys on the list who are, and hopefully they'll correct me if I'm wrong


Here's the deal--you need to know the ohm rating of your cabs. The mag 300 head can run a minimum load of 4 ohms--no less. If you hook a 4 ohm cab to the head, that's it, you can't add any additional cabs.

But if you have a single 8 ohm cab, you can add a second 8 ohm cab--two 8 ohm cabs together will show the amp a 4 ohm load.

For example, I have a 4 ohm 2x 12 cab--you could use that. I also have two 8 ohm, single speaker cabs--I can use both those 8 ohm cabs, because when they are linked, the amp "sees" 4 ohms. But I could not use a 4 ohm cab, and an 8 ohm cab together--that would bring the impedance down to less than 4 ohms. I could not use three eight ohm cabs either, for the same reason.

So check the rating on the cabs you want to use. 2 eight ohm cabs =4 ohms.

As to the wattage, you can use the 307 watt amp with a cab rated for 450, and you should be fine. But you can still blow speakers. Speakers usually blow when A: the cone of the speaker is forced beyond its range by some big spike in volume, or B: the voice coil, the thing that translates the signal into speaker movement, overheats and distorts or actually melts

As I understand it, you should be pretty safe witha 307 watt amp into a cab rated for 400 watts. But if you send a the wrong kind of signal--say, a really distorted , heavily effected signal--you could oveheat the voice coil and blow the speaker. In my opinion--and again, I'm not an expert--you'll be fine if you don't constantly push the amp to its extremes

As to volume, it's hard to give a clear answer about what's louder. Cabs all have different efficiency ratings. Some aree louder than others, some sound louder than others but maybe aren't, because the emphasize different frequencies. For example, you can make a cab louder by sacrificing some low end. Generally, more speakers equals a louder and fuller sound. But it depends on a bunch of different things

A student of mine has this stack -- with 4x10 and 1x15 cabs. It sounds killer (in his house!). However, based on my experience with amps, there's more than enough juice in this rig to run a big gig. Oh, and yes, we were running my upright through it. It sounds even better with BG of course.

Good luck.

.... sorry guys, i have a problem.... i am talking about the ashdown mag 300 with a 2x10 deep cabinet !

THE E-Bass is only turned about half of the upright and gets the walls shaking (AND THE NEEDLE MOVES). So is it ok to turn it almost 3/4 up for the upright (with a cheap pedal pre amp) or can i destroy sth ?

Ha ha! :)

Seriously though, is your Ashdown Mag 300 the combo, or is it a head with a 2 x 10 cabinet. I'll offer you a very uninformed opinion, and then maybe someone will be able to help you better than I.

I don't see any reason that a combo amp should blow it's speakers, even if you had it turned up all the way. The speakers should come from the factory matched to the head so they don't blow, even at full volume.

Even if your 2 x 10's are a separate cabinet, most 2 x 10's should be able to handle 300 W safely.

My previous post is half serious! If you've got your volume set at a level that's so loud you're worried about blowing speakers, why would you want to go any louder? If the volume isn't loud enough, that's a good indication the speakers are prepared to offer more volume safely.
