Audio Pro Focus SA-4 Bookshelf speakers

The peculiarity of the layout of drivers and bass-reflex port on the facade of Audio Pro Focus SA-4 serves to improve the harmonization of radiations in different frequency areas. The body made of 18-mm MDF is tightened by a partition and rib stiffeners. In filter there are coils with air core and 250V paper capacitors. A massive woofer with a shielding cap has a double sound coil. The declared upper border is 32 kHz. The bass-reflex pipe on both sides is equipped with "anti-turbulent" nozzles. Respectfully.

SA-4 correctly transfers timbre portraits of musical instruments, allowing to achieve the high measure of naturalness of sound. There is a lot of air and hall is felt well. HF-part of the spectrum is elaborated in details, with a slight pressure. Tube sounds brightly, without distortions. Some emphasizing of the upper edge of the range causes a slight accent on hissing sounds (vocal).

Audio Pro Focus SA-4 is a competently designed, well manufactured, quite universal speaker system. If you plan to purchase a subwoofer in addition to it, you can try to use it for music systems too. In home theatre there is the sense to use the pair as a front and as a rear.
