I've always known open cabinets from combos and closed cabinets from using heads (old Fenders).

However all of you have expanded my horizons, or at least made me recognize my lack of knowledge.

Please enlighten me as to the reasons for your preferences.
 
Depends on the amp, and the sound you’re going for. I have no preference for either (and there’s a third category, ported cabs), but amps are often voiced for a particular design. Come to think of it, I have all three on hand.

A good example is the HXDA (and many Marshalls). They sound great with a closed back cab, and less great with an open back cab to me, although Duane Allman was said to open up the backs of his Marshall cabs and use them with EV speakers.

The DG definitely sounds better to me with an open or ported back cab than a closed back cab, and best with the cab designed for it. Same holds true for most amps I’ve had over the years.

Often amps are marketed with matching cabs and particular speakers. In the case of reputable amp companies, in most cases I’ve found it’s best to use the type of cab (open, closed or ported) that the amp is developed with.

I absolutely agree. My Marshall head sounds better with its matching 4x12 1960 Vintage closed back. My Two Rock was amazing with its 2x12 open back cab with Scumback speakers. The Two Rock with open back had a 3D sound that filled the room.

I built my cab with a removable panel so I could do both. After doing a bit of testing and evaluating I found I like the closed back for improv & leads and open back for chords and rhythm work. Not that I'm going to remove or replace the panel mid set but I can cater to the gig so if I'm backing up a singer I can go open and if it's a jam session that I want to punch thru the mix, the closed back works better.

I find it makes a big difference too, especially in cutting thru the mix with heavy handed drummers and volume greedy bass players.
 
I really liked the Royal Atlantic 2x12 cab. It was ported so it had some punch and some air.

The DG cab is ported and exhibits those same characteristics. I had a ported Two Rock cab when I played TRs that did the same thing.
