Can this work? 1 head, 2 cabinets? do YOU see any problems here?

[bommer]

i have the XS400H Yorkville head (almost positive that's the model of the head)

anyways, i have a 410 cabinet (XC410) and an older crate 15" cabinet. Since the head has 2 speaker out jacks, would it work to plug both cabinets in at the same time with just the one head?

also, could this ruin the cabinets? the only thing i can see happening is the 15" blowing because of too much power from the head if it gets cranked.

2nd also, with both cabs plugged in, will each cab only get a partial ammount of the heads amplification power?

thanks

Very simple.

1) Check specs on the head. What is the MINIMUM impedence it will drive? (8 ohms, 4 ohms or 2 ohms?)

2) Check specs on speaker impedence. WHAT is the impedence of each cab? (Normally 8 or 4 ohms.)

Report back with both pieces of data and we will tell you if it's OK. (Or just take that info and surf TB for an answer - it has been discussed dozens, if not hundreds of times.)

Connect two cabs without knowing the info above and you risk melting your amp.

You need to know the ohm rateing of the cabs & what your head will take.
Beat me to it!

What they said! And yes, it will split the power between the two cabs. How it is split depends on the impedence.

The head says: Speaker outputs - Min 4 Ohms
Yorkville XC410 says: 8 Ohms impedance
Crate 15" says: ?

couldnt find the crate Ohms for the cab, but, i did find the PDF. any able to spot the cab Ohms?

The 410 is 8 ohms.

I believe the 15 is 4 ohms, and rated for 150 watts.

If I'm correct, you won't like that combo of cabinets even if the amp will support them.

ahh alright. just trying to find something to do wth that cab, cause the b150 head is givin me some buzzin. thanks for the help!

If you have a ohm meter check the resistance of the 15. If it measures under 4 ohms it's 4 ohms. If it measures over 5 ohms it's 8.

[BassmanPaul]

Absolutely! If the 15 is 4Ω it will receive twice the power of the more capable 4x10. It'll be toast in short order. A 4x10 + 115 is a bad pairing in the first place.

If the quoted figures are correct you risk damaging your amp with a load of 2.67Ω to a 4Ω minimum amp. Not a good idea.

I run one ampeg into 2 8 ohm cabs for a 4 ohm load. This is my normal setup.

That's why it has two jacks.

[lo-freq]

Yeah, from the pdf, the speaker in the combo is 4 ohm and won't work in combination with your other cab.

alright, thanks for the help everyone
