CLS: Exactly, I´ve seen and heard Petters multicells IRL and that inspired me to build a pair myself. The construction techniques are pretty much the same...

PureAudioProject just confirmed that its latest Trio15 configuration is now available for pre-order. As Ze'ev (Wolf) Schlik, the founder of the modular speaker company explains, the Trio15 Coax10 project is a step closer to the realization of its original vision.

Music with the Duet15 Open Baffle Speakers is open and big, even in small rooms. Absolutely no compromises on tonality and music presentation.

Cool - and yeah, big fun! And btw., this is by far the best use of a closet door :rofl: Just a question: are the crocs of the planars insulated? They are...
