The black C5212-64 Acustica Series 500W Passive Speaker from RCF is a full-range versatile two-way loudspeaker. It offers substantial power and efficiency for several professional applications. The speaker can be used as a main unit in permanent installations, or as a supplementary fill in large speaker systems.

The Constant Matching Design technology helps guarantee an optimal transition between the high-frequency horn polar pattern and the low-frequency woofer directivity. The horn can be rotated, allowing you to install the loudspeaker either vertically or horizontally. The hi-frequency transducer is a 1.4� RCF precision compression driver with a 2.5� voice coil. The low-frequency transducer is a 12� RCF precision woofer with a 3� voice coil.

The speaker also includes a high-level crossover network that features low induction values in series with the woofer. This innovation, named LICC (Low Impedance Compensated Crossover) delays reduction, reduces phase shift, and lends superior transient response.

The dynamic high-frequency driver protection is accomplished with the RCF AMCDP (Active Mosfet Compression Driver Protection System), which is chosen to complement the driver power curve.

The internal crossover can be easily bypassed for bi-amplification. The cabinet is made of Baltic birch (heavy duty painted) and allows different installation options. It comes equipped with top and bottom multiplates for either wall or suspended mounting with chains. The installation points are available on its rear panel as well. The steel front grille is protected with a double layer polyurethane fabric and the front RCF logo is easily rotatable. Connections are made through 2 Neutrik SpeakON NL4 connectors (audio input and parallel link output).

Nice Chair but it does not work for long.
Color: Black
This is a very good chair when you buy it. Comfortable and fits bigger people well. The issue is that you only get to enjoy it for one year. After one year of very light use the main seat piston that adjusts high has already failed leaving my chair stuck at the lowest height. I could not imagine how fast it would have failed if I used it a lot. I did not even sit in this chair more than 3 days a week for 2 hrs. I am nowhere near the weight limit for the chair. It just does not last.

Ergonomic Office Chair
Color: Nori Black (Pu Leather Seat), Color: Nori Black (Pu Leather Seat)
I’ve been using this ergonomic office chair for about a week now and honestly it’s one of the best upgrades I’ve made to my workspace. The chair was easy to assemble, feels very sturdy, and the mesh back keeps it breathable during long work sessions. The lumbar support is surprisingly comfortable and actually helps with posture, especially if you sit at a desk for hours every day. The seat cushion has the right balance of firmness and comfort, and I like that the armrests and height are adjustable to fit different setups. The wheels roll smoothly and the chair feels stable even when leaning back. Pros: ✔️ Comfortable for long hours ✔️ Great lumbar support ✔️ Breathable mesh back ✔️ Smooth rolling wheels ✔️ Modern clean look

This office chair is comfortable, supportive, and looks great in my workspace. The adjustable lumbar support helps reduce back strain during long work sessions, and the flip-up armrests are convenient when I need extra space.
