the -3 position decreases the output of the tweeter relative to the woofer. The 0 position is the factory setting and generally provides the most natural response from the speaker.

The use of a 70 Volt transformer allows several HS-615 speakers to be used together by running a speaker wire from one speaker to the next in a parallel connection when using a 70 Volt amplifier (as shown in the wiring diagram below).

WARNING: Refer to the wiring diagrams and voltage selector sections to properly install a 70 Volt system.

Wiring Diagrams

CAUTION: If your amplifier isn’t capable of handling the impedance of all connected speakers, this may result in overloading the amplifier and may cause possible damage to the amplifier. Check your amplifier’s documentation for proper impedance levels.

Parallel Connection

A parallel connection exists when speakers are connected directly to an amplifier (as shown in the illustration below). Each speaker’s positive terminal is directly connected to the amplifier’s positive terminal, and each negative terminal is directly connected to the amplifier’s negative terminal. This type of connection should be made when using a 70 Volt amplifier.

In this example, each speaker is set to 70 Volt operation and is being powered by a 70 Volt amplifier. If the speakers were set to 8 Ohm operation, the total impedance (using Ohm’s Law) equals (8 x 8) ÷ (8 + 8) or 4 Ohms, which may be too low for some amplifiers. Make sure to properly select 70 Volt or 8 Ohm operation before connecting the speakers to the amplifier.

HS-615 specifications

The RBH Sound HS-615 is a premium home audio speaker that seamlessly combines advanced technology and superior craftsmanship to deliver an exceptional audio experience. Known for its ability to reproduce sound with unmatched clarity and depth, the HS-615 is an ideal choice for audiophiles and casual listeners alike.

One of the standout features of the HS-615 is its sophisticated driver array. The speaker is equipped with dual 6.5-inch woofers that produce deep, resonant bass. This is complemented by a 5.25-inch midrange driver that expertly handles the vocal and instrumental ranges, and a 1-inch silk dome tweeter that ensures crisp, detailed high frequencies. This three-way design allows for a fuller soundstage, making it ideal for both music and home theater applications.

The HS-615 utilizes RBH Sound's proprietary technologies to enhance audio performance. The company's carefully engineered crossover network ensures that each driver operates within its optimal frequency range, resulting in a seamless blend of audio frequencies. This minimizes phase distortion and maximizes coherence, providing a more natural listening experience.

Another notable characteristic of the HS-615 is its impressive sensitivity rating, which allows the speaker to deliver a powerful sound output even when driven by lower-powered amplifiers. This versatility makes it a suitable addition to both high-end systems and more modest setups. The speaker's nominal impedance of 8 ohms also makes it compatible with a wide range of amplifiers, giving users flexibility in their audio configurations.

In terms of aesthetics, the RBH Sound HS-615 is designed to fit elegantly into any home environment. The cabinet is crafted from high-quality MDF, which not only provides durability but also minimizes unwanted resonance. The speaker is available in various finishes, allowing users to choose an option that best matches their decor.

Overall, the RBH Sound HS-615 speaker stands out as a fantastic choice for anyone looking to elevate their audio experience. With its impressive driver assembly, advanced technologies, and elegant design, it captures the essence of true high-fidelity sound, making it a worthy investment for music lovers and home theater enthusiasts alike. Whether used for casual listening or immersive cinematic experiences, the HS-615 excels in delivering an audio performance that captivates and satisfies.
