The Spendor Classic 4/5 is truly a great bookshelf friendly speaker. The cabinet is not ported and is only 6 1/4” deep. They might sound best on stands out in the room but actually sound very good tucked away on a shelf.
Moving on a sailboat - bookshelf speakers?
I've decided to spend a year on a sailboat. I'm loath to give up my home system as it's about as good as you can get before spending silly money. (LX521s, ATI/Parasound, maxed-out Linn LP12 with Blackbird arm and VdH Frog) All of it is going in storage except for my Ayre QB-9 Twenty powered by my M1 Mac Mini.
I am interested in opinions on great bookshelf speakers that actually need to live in a bookshelf. (No room for stand-mounted speakers in a 40' monohull sailboat.) I also need a good integrated amp to power the speakers. (I'm leaning towards the Audio by Van Alstine Vision SET 120 Control Amplifier.)
I think I've got about 18" tall by 12" deep as limitations. Maybe less. (I'll update when I know for sure.)
What speakers should I be looking at? Various reviews like the KEF but declare that it needs stands. Others declare the sub-$1000 B&W anniversary speakers and don't mention stands. I wish I could fit a pair of LX Minis, but the associated mid/bass tube knocks it out of the running.
