Ampeg SVT cab and head advice please

[David Potter]

I currently have an Ampeg SVT 450 head and a 410 Classic Cab the head says 450 Watts at 4 Ohms my cab is 8 ohms how can I get maximum 450 Watts power? also getting a Ampeg 810 E will the SVT 450 drive that sufficiently at 450 watts into the 2× 8 ohm cab? or excactly do that work?
Any info would be very helpful thank you

You have an 8ohm SVT410he? Get another one and both cabs together will create a 4ohm load for your amp.
Or, use one SVT810e (4ohms).

Thank you for the info.
So the 810e 2 x 8 ohms cabinet is 4 Ohms for the SVT 450 head and will give me the full 450 Watts am I correct in this or mistaken?

Yes, the 810e is 4 ohms or you can split it into two 8 ohm cabs. But with a 450, you wouldn't split it. Just run your speaker cable into the mono input on the cab and the head will recognize it as 4 ohms.

1x SVT410he = 8ohm
2x SVT410he = 4ohm
1x SVT810e = 4ohm

If your head is rated at 450watts at 4ohms you’ll be getting 450watts with a 4ohm speaker load. With an 8ohm speaker load you’ll have less wattage from your amp. How loud you are is player/eq/volume control/band/room size & shape dependant.
