Owner's Manual​


The D4-16 is a dual 4” speaker that is perfect for home audio systems, restaurants, patios, conference rooms, and much more. The dual speaker design disperses the sound wider so you can evenly spread the sound in any room.

The final impedance of this speaker is 16 ohms allowing you to connect 2 or 4 of them per channel to your amplifier or receiver. Each speaker can handle 50 watts RMS and 200 watts peak.

Why 16 Ohm ?
16 ohm is great for applications where you want a lot of speakers.
You can run (4) 16 ohm speakers wired in parallel to each channel of your amplifier and end up with a 4 ohm load which is perfect for almost any amplifier on the market.
This is great for large home audio systems, restaurants, large patio systems, and other commercial applications. You can also choose to run 2 or 3 speakers in parallel to each channel of your amplifier.

Our 4 way swivel bracket allows you to angle the speaker up, down, left and right for optimal sound staging. The sound these speakers produce are both rich and full. They include large 9.75 oz magnets and the tweeter is an audiophile grade silk soft dome tweeter. We also have a built in 2nd order 2500Hz fixed crossover that protects the speaker and creates a great sound curve for indoor or outdoor applications. The detachable euro-block terminals make installation quick and easy. The terminals work with ordinary speaker wire.

Owner's Manual​ ​​


The VOL850 by Rockville is a wall volume controller that works with any standard home audio or pro audio system that operates with 4-8 ohm speakers. Our volume controllers are some of the best on the market. The reliability and accuracy is what makes the difference. Our 11 step controller is precise and accurate.

The VOL850 supports speakers connected to it that add up to 50 watts RMS per channel or less. For example you can connect (2) speakers that are each 50 watts.

The euro-block connectors make installation easily. The terminals are fully detachable. We use a beautifully designed plate that will seamlessly match your standard decor. These are a standard 1-gang size for easy installation. Internally the circuit board is protected from dust build up to ensure long life.

What is a volume controller?
If you already have a multi zone amplifier then you can go out from any zone and into this volume controller and then out from the controller into the speakers (each speaker is wired from one to the next in parallel). The end result is that you can access the volume control from that room without having to change the volume from the amplifier itself.
