DeForest (Philips) homebuilts, Celestion Ditton 66's, Boston A70's, Dynaco A25/A35s
First, I'll gladly say I'll be buried with the Philips DeForest-driver based homebuilts I made when I was 20 - they still sound excellent 32+ years later. My Dad bought me the drivers and cross-overs as a birthday gift - I moved away from home (moving from the Toronto area to Montreal) when I was 19, and he knew how much I loved music. I built the cabinets per the DeForest book (shallow cabinets to avoid standing waves near the cross-over point) out of 1" pressboard, so though they're only just over 26" tall and 15 wide, they still weigh about 35lbs each, sound excellent, and have given me over half a lifetime of enjoyment.
Others I'll probably be buried IN are my Celestion Ditton 66's, which really are the only other speakers I've ever owned that I truly believe are an order of magnitude better than my home-builts or almost anything else I've heard. Mind you, they're over a meter tall, weigh well over 60lbs/ea (I think), but they have an ease, presence, image and clarity that's hard to beat. Plus a bottom end that can shake the house when the source material calls for it. Remarkable!
My two pairs of Boston A70's are really amazing speakers... I couldn't part with those, either, especially at the $15-20/pair I paid for them
I'm also really fond of my old Mirage SM-1's - smooth, clear, lots of bass when the material calls for it.
Lastly, two of my other real favourites are my Dynaco A35's (given to me by my dear friend Rick in a fit of lunacy) and a pair of Dynaco A25's I just picked up at a thrift shop for $9 the pair, plus a few bucks for ultra-fine steel wool and some oil finish to bring the walnut cabinets back to original beauty.
Mind you, I also have some rarities... a pair of Oliver's (with upgraded tweeters) that really sound amazing - a small manufacturer from the Winnipeg area - and a pair of AudioAnalysts that I think were from the very early 70's, still sounding very good. Though those phenolic-surround tweeters have never really impressed me, they sound fairly well matched on the AudioAnalysts. Anyone of my vintage may remember the AudioAnalyst woofers? They have an open "cross" of some kind of glue or caulking adhered to the surface - presumably to both stiffen the cone and add mass to drive the resonance frequency downward.
I've got to "thin the herd" someday... it's just so difficult. Nice speakers are like pigs or cattle - after a while they're like family.
UPDATE: I have sold the Olivers - they've "gone home" to an enthusiast in Winnipeg, who's using them as his rear channels, and a pair of 4' wide, 200+ lb/ea Oliver studio monitors for the fronts. Wow would I like to hear that someday. I have also sold the AudioAnalyst speakers to a new "collector", who's enjoying them very much so far.
