RD-Series 500-Watt Monoblock Subwoofer Amplifier @ 2-Ohms.

Born to produce a whopping 500 watts into 2 ohms (14.4V, 1% THD), the RD500/1 amplifier was engineered to generate tons of pure subwoofer bliss from a sleek, ultra-compact chassis. The secret behind its power proficiency is JL's proprietary NexD™ switching technology, which delivers large amounts of power output with precise efficiency and ultra-low distortion.

For your convenience, the RD500/1’s controls are located on top of the amplifier, beneath a protective cover, with all connections found along one side of its chassis. Signal processing features include a 12 dB / octave low-pass filter, with continuously variable frequency selection from 50-500 Hz, and a variable bass boost EQ. Dual-range, differential-balanced inputs are also on-hand, capable of accepting most input voltage levels. Automatic turn-on capability (via signal sensing or DC-offset sensing) is standard, along with a set of preamp outputs so you can easily pass signals to another amplifier.

The RD500/1 is also equipped with an onboard LED-clipping indicator. This all-new, innovative feature lets you easily set your amplifier’s input sensitivity setting, quickly and accurately, with no special equipment needed. The RD500/1 features a durable, black powder-coated finish and a top-mounted, dual-color LED light strip that reports the overall status and condition. With the addition of an RBC-1 remote level control (sold separately), you can control the subwoofer output directly from the driver’s seat.

Perfect everyday Watch
Color: Grey, Color: Grey
Super happy with this watch. It looks really clean and goes with pretty much anything dress it up or wear it casual. The blue face is fire in person and catches the light really nicely. Feels solid on the wrist, not too heavy, and the quality is definitely there. I’ve been wearing it almost every day and it still looks brand new. For the price, you really can’t beat it. Great everyday watch that looks way more expensive than it is. Would 100% buy again

Stylish and inexpensive
Color: Grey
Great watch. Came in quickly from seller. Got it sized at a local shop. It’s a pretty stylish watch for the price point. I don’t have big wrists but I still think the face could be a little bigger. But it’s pretty sleek and I’m happy

Swiss Quality from a good brand
Color: Grey
This is my 4th Tissot watch. I only have a few quibbles. The band adjusts by removing wide or narrow pieces, not by adjusting with pins with a range of holes. I prefer that way to adjust a metal band. The color blue of the dial is darker in real life than the picture. I also wish the day indicator was a little larger (or my eyes were younger).
