Sealed Loudspeakers?

What size, budget ? Spendor S3/5 and Harbeth and Stirling Broadcast LS3/5 derivatives are sealed.

Why are you excluding bass reflex designs ?

Small to medium floorstanders prefered.
no budget limitations.

I prefer acoustic suspension designs.

The two compainies that I know that still produce as speakers are Allison and Cambridge SoundWorks:

Most, if not all, NHT speakers are acoustic suspension.

Although NHT might not have as blue blood a high end pedigree as the speakers Seantaylor99 mentioned, they do have some claim to lineage from the Golden Age in the U.S. -- one of NHT's founder's, Ken Kantor, used to head R&D at Acoustic Research, the birthplace of the acoustic suspension design. (Granted, he was there about thirty years after AR first developed the design.)

I think NHTs do some things quite well and are reasonable values. Worth checking out.
