Post Subject: ALE/Yamamura's Six ways systemPosted by twogoodears on: 8/4/2013

Hi Roman... the installation is a combined joint-venture between Endo-san of ALE (bespoke drivers and horns) and Be Yamamura's (45 W solid state Class A amps and digital software and hardware).
Jean Hiraga, like myself, were only invited to taste this system and the ongoing fine-tuning, yet he wasn't involved in ANY way in the system making.
The listening session was both satisfying and (sort-of) limited, as the digital library was in the making and the tuning of the system still was a work-in-progress, due to minimal adjustments mostly performed in drivers/horns delays and integration.
I've been told by Be Yamamura that phase and delays between the ways are managed via the powerful software (and usual measuring mike, etc).
The interesting question about digital crossovering will be asked by yours truly directly to Yamamura-san, soon: more details about frequencies cut-offs, drivers used will be implemented in the Blog asap, as given by the system landlord himself.
Sound... mmmhhh... it's natural, effortless, not so deep bass, meaning the sense of stomach punch associated with woofers isn't here... a light, airy low end is here, instead.
BTW: the system owner told me about his next step - i.e. adding another tweeter, bringing the system to an awesome 7 ways, with very specialized drivers and ultra linear and limited bandwidth... I expressed some doubt about redundancy and loosing the target risks.
Anyway, it's a system worth a listen, Roman... workmanship is top class, cost-no-object and I'm sure the result when such a complex system will be tuned will pay-off the (huge) investment.
