Need receiver help with situation.

[Copywriter]

Hi guys,

Here's the situation. I have a receiver from the Eisenhower administration and I want to upgrade. And it's a non-working 5-disc DVD player too (woo hoo). Time to upgrade.

Right now, I have a 5.1 system that's in the ceiling. I can't cut any more holes or anything.

The receiver I want is the 7.1 Onkyo 605.

Would this still work or do I need to find a 5.1?

One idea would be for me to add 2 speakers on the ground somewhere (recommendations for budget-friendly ones?).

The 605 looks like a nice receiver and it's in my budget for this project.

Thanks
