STP-Rectus 2x4 Active Studio Monitor

Rectus series has a lot of high definition and flat frequency response. We're reviewing here rectus 2x4 Atlanta model which is unique and completely professional in a thick 7 heavy wooden housing.
It comes in a wooden box as completely packed.

The box was sealed with nails so we'd have to almost crack it open. Inside there was epp-foam and then cardboard box and finally speakers inside.

Here is what was written on manual and box. The same text which defines it is written on their page also:

The Rectus 2x4 are the two way desktop studio monitors. The combination of our special two way audio system consist 4'' Subwoofer and 1.5" dome tweeter are designed to provide flat response within the wide audio range 38Hz to 30Khz. 

The applications & uses of these studio monitors are best as "Mixing & Mastering" music tracks. The best vocal response is achieved as the combination of tweeter & subwoofer which provides cleanest sound at even its maximum level. The sound at all of its frequency ranges is completely flat.

Rectus 2x4 is completely comparable with most of the 8'' professional reference studio monitors.

Additional amplifier isn't required (in case of Rectus 2x4 Atlanta) because it has built in "Amplifier". The amplifier is also just like speaker is designed to give flat response at frequency ranges it is designed for.

Rectus 2x4 is still the best choice for alot of users. Beside these are old models but still not discontinued by the manufacturer "our STP Professional Audio Team".
