The first question was whether it was possible to develop a bookshelf speaker which would offer a voluminous sound and low frequencies even without a subwoofer.
It was developed the PACTO, a shelf speaker, built as a so-called FAST system (full range and subwoofer technology) in an inconspicuous bass reflex housing. The W 130 X - 2 x 4 Ohm allows an extremely low limiting frequency of 42 Hz and is supported in the mid-range from FR 58 - 8 Ohm. The two drivers are separated at 250 Hz by a simple serial switch with only three components. Therefore, only one speaker is responsible for the very important voice range, WAS makes the sound appear extremely precise.
The double-layered baffle can be color-deposited from the rest of the casing and thus enables more freedom of design while building the casing.
Thanks to the front bass reflex opening, the relatively small speaker can be discreetly placed on a shelf and still fills your living room with a rich and full sound. Thus, the PACO is our first compact shelf box, which we can gladly accept to everyone without the subwoofer recommendation.
