Title: Constrained directivity OB Speakers
Post by: zydeco on 23 Oct 2016, 04:20 pm
I'm a fan of constrained directivity speakers and am wondering about open baffle versions of this concept. The default choice seems to be the Spatial Hologram M3 / 4 series which have received good reviews. It seems though as if Pure Audio Project has introduced something similar (albeit not a point source) with the Trio 15 Beyma (see http://www.pureaudioproject.com/product/trio15-beyma-tpl150-open-baffle-speakers/ (http://www.pureaudioproject.com/product/trio15-beyma-tpl150-open-baffle-speakers/). Has anyone heard the Trio 15 Beyma and, if so, then what is the impression?

It appears as advice to DIY something similar to the speaker you asked about. 

I have never heard the Trio, but have read good things.  I have dealt with the Canadian distributor and can absolutely recommend Rachel at Grant Fidlelity.

Still interested in a comparison of Spatial M3 Turbo and PAP Trio-15 150 or Horn-1. A key feature for me is constrained directivity. Any feedback?
