How bad is it to mix speakers?

My 210 cab seems to be falling apart but the speakers in it are still good and I happen to have a pair of 10"s lying around, so how bad would it be for me to buy this cabinet: Link Removed and just put all four speakers in there? I have two madison knight 10"s and two peavey scorpion 10" speakers. I dont need it to sound super good, but I don't want it to sound horrible.
 
Forgive my stupidity, but how do I find out the peak impedance of my speakers?

Oscilliscope.

I haven't used one yet, but it puts a signal through the speaker (or anything) at different frequencies and measures the response in different ways, in this case, impedance.

Or the manufacturer, who has done this already, might be willing to tell you.
 
Is anyone sure that each driver has its own enclosure? It does appear that way, but it is kind of hard to tell in the picture.

Also, my amp has the option to output to two channels. Would it be louder/better to just wire it like two 210s and put the two sets of speakers into different channels? I have a hartke 3500 and it would be 350 watts vs 240 watts in two channels.
 
I disagree...that cab looks like it is all one chamber which would not be good. It's hard to tell though.

But, assuming it is separate chambers, what are the impedances of the speakers? They all need to be the same if you are putting them in the same box or you will end up with an odd final impedance.
 
It doesn't have separate chambers - what you see there is the bracing they've added for some torsional strength. Trust me, I had one of those cabs for a while.

Based on my experience with the Knight 10" drivers, I would DEFINATELY agree with fdeck and go with a pair of the shred-built 210 cabs. I did and I'm MUCH happier. I use them for practice room work and they pump out more lows that the 410 could ever muster with those drivers.
 
I would have to say that I would go with the 2-10 idea because the only way you would want to mix the different subs like that is if you have them in their own enclosure which we know thanks to the posts above is not the case with that cab. plus then if you aren't doing as big of a show you can just bring the two madison knight 10"s and leave the peavey's at home!
 
I would not use the OSB, but that's just me. Lots of people like MDF, particle board, for speakers since it doesn't resonate the way plywood can.

Back to mix and match speakers - No way to know until you try it. I once loaded a 4-10 with 2 100 watt Eminence, one Dayton sub, and a 50 watt Eminence guitar speaker. Sounded good if you were out a ways, but standing right in front of it the guitar speaker cut like a knife. It was a good reason to use the wireless and play from the dance floor. Looked like a fool, I did.

Best bet is the two 2-10" cabs. Much more flexible. Are the drivers all 8 ohm? If your amp can not handle a 2 ohm load you may want to wire the cabs in series. Together they will be 8 ohm, separate they will be 16. Not quite as loud separately and sucks if you burn up a voice coil, but better than frying your amp.

Good luck!
 
Wow, this is an easy question tha really got nuked. The impedence is listed on the back of the speaker, or you can simply google the speakers to find the impedance for the speakers. The speakers in question are fairly new, so their info is readily available.

After that, it is just a matter of how you want to wire the box up. you can run 2 10's to right and 2 tens to left...you can run all for off one input...etc. There is a great wiring write up on the shavano site.

There are many guitar players that mix and match speakers, I don't see why a bass cab would be any different. As long as you can do math and read, you should be able to figure out how to wire up four speakers to work well together and meet the ohm requirements of you ramp.

Yes guitar players do but most often in an open backed cabinet. We are discussing a bass player and sealed or ported cabinets and low frequencies.
