Cab Wiring

[RooseOnBass]

Is this the correct connecting up of an Ashdown ABM 500 RC Evo II head paired with an Ashdown MAG 410T cab (450w) and MAG 115 Deep cab (250w)

Both cabs are 8ohms. Do I have this connected in series or parallel? I want a 4ohms load, not 16ohms which people say certain wiring can do. Obviously I don't want the smaller cab being overpowered you see.

Thanks

Since both cabs are 8 ohms, the connection you have is a 4 ohm load as far as the amp is concerned.

You’ll have to listen carefully for signs of distress from the 15. Rated at nearly half the power of the 4x10 it will be a limiting factor in your system's performance. After 500W the 15 will be over powered whilst the 4x10 will be barely cruising. It’s why the pairing is a poor one.

Since when has it ever worked like that

Wasn't my question anyway, was it? The 115 won't reach that point because it'll never be bring overpowered, as it's used for live settings only with microphones and a PA

It works that way due to the laws of Physics. With both cabinets being 8Ω the available power will be split equally between them. A 500W rated amplifier is very much capable of way more distorted.

I decided to inform you of the possible pitfalls of mixing cabinets. If you object to my well intended post then do what you want!

The connection looks right, the positioning not so much. The speakers are in parallel. Without a series box or special cable, no configuration of wiring will put them in series.

Yeah the positioning wasn't to stay that way to actually be played.

If you are thinking that it is a total of 5 speakers that will split the power evenly, then you are wrong (if not, then sorry, but it has come up before).

The connections look right. If the size of the boxes will allow you, I suggest putting the 115 on top of the 410 when you use them both . This way, if you do get into a situation that the rig is being pushed hard, you will be more likely to hear the 115 struggling before anything bad happens.
