The reason why the Cabs do their best at 4 or 2-Ohms is because you are getting the most efficient use of the Amp and the Cab as they were designed to deliver.

However, I admit that I don't know why someone would choose a 4 ohm cabinet over an 8 ohm, other than to match it up to the amp they already own, or plan to own.

Question: Why 4 ohm or 8 ohm, other than the reasons I've listed?

What are the major differences and advantages between the two? Educate me, Please!

Ok, wow, I could really make this a long answer, however, I'll try and keep it concise:

Choosing the right Cab depends on the end result the player is seeking. If you are looking to push alot of air, then two Eden 8-Ohm 410 XLT's are going to push way more air than 1 Eden 4-Ohm 210XLT. The Amp is still delivering 500W+ at 4-Ohms, but you have more coverage with the 2 8-Ohm Cabs.

Check out Al's new rig: http://www.smithbassforums.com/showt...7475#post74901

He has a 410XLT and a 115XLT. Both are 8-Ohm Cabs. These two Cabs will draw 500W+ from the WT-550 at 4-Ohms (i.e. 2 8-Ohm Cabs. = a 4-Ohm load against the amp). This is a great set-up and most likely meets his needs.

Now, if Al would have opted for, say, one 4-Ohm 210XLT, he'll still get the 500W+ from the Amp, but guess what; no way he'll push as much air. Doesn't mean the 4-Ohm 210XLT is inferior, just means the 4-Ohm 210XLT would make more since used in a smaller setting.

Or, hey, how bout this one: One 4-Ohm 210XLT + one 4-Ohm 410XLT. Now you'll draw the 750W+ from the WT-550 at 2-Ohms and that may be all you'll ever need. Or will it? This set-up still won't push as much air as 4 8-Ohm 410XLT's, but maybe you won't ever need to cover that much area with 4 8-Ohm 410XLT's. Or will you? LOL!

I could've picked any combination of 4 or 8-Ohm Cabs depending on what I know I want to hear from a particular speaker and Cab design. Yeah, Cab design; but that's another topic. 8, 10's, 15's, 18's, etc. inch speakers have different frequency responses. Yeah, that's also another topic.

Bottom line, you need to decide how much air your want to push; you need to know what you want to hear from your speakers within the optimal Cab design. David Eden understands this and this is why I choose Eden Cabs.

Pick your speaker configuration and Cabs wisely and know the Amp you are using to drive them.

Hope this helps some.
