I've taken to building a cab for my amp - just finished some physics studies and figured there's no better way to utilize it than to do some Thiele-Small and standing wave calculations.

That said, i'm having a bit of a problem with impedance matching -
i've scoured google, but seeing as this isn't too standard i'd rather double-check than find out the hard way;
It's an 8 ohm amp, and i want to connect it with three 8 ohm speakers.
Now, two of these actually test out @ 7 ohm each, and the third one, who came stock with the amp, tests out @ 6 ohms - meaning the closest i can make it is a 9.5 ohm impedance.

What i've read through forums suggests you can connect a higher impedance cab to a lower impedance amp, but not vice versa. I also know that the average impedance range for amps nowadays is ~3 ohms.
Thing is, if a 6 ohm speaker works with my 8 ohm amp, wouldn't that be risky?
and if it isn't, did i get something wrong reading through the forums?

Last, and most importantly - what are my chances of blowing something up connecting a 9.5 ohm set up to a 8 ohm amp?

I'd appreciate any help concerning. Thanks in advance.
