Speakers made with unusual cabinet material

solid wood = resonance problem. it's only for consumer's attraction. veneer is much simplier, cheaper and better.
exotic materials such as marble are too expensive. gotta be makin over quarter million after tax if you want to have those.
i was intrigued by performance of Event Opal active monitors enclosed in santimeter thick aluminium chassis where amps have no heat issues at all at any usage or abusage.

Not if it's done right. Although doing it right may result in a cost disadvantage relative to veneered approaches. See the comment by Daedalus_audio in the thread I linked to earlier.

The original B&W CM1 (1987) had a plastic matrix enclosure.

B&W Nautilus 801/802 midrange enclosures are Marlan.

Unity Audio made some speakers with Corian cabinets.

Essence made speakers with cast concrete enclosures.

Waterfall speakers have glass cabinets.

Doin' right with veneer will not compromise doin' right with solid wood only with smaller expense. Next move of solid-wood or any other higher-priced materials manufacturer is to convice consumer.

In the case of Daedalus speakers, a lot of consumers are already convinced, as can be seen in many owner comments that have been posted about them here and elsewhere, including in the thread that I linked to above. The proof of the pudding is in the eating, as the saying goes.
