Excursion Rx-6C Eco - 2-Way Sq Speaker System

Excursion RX-6C ECO – 165mm Reference Separate Speaker Set

Excursion RX-6C ECO is a 2-way car separate speaker set from the RX Reference series. The set uses 165mm mid-woofers, 25mm silk tweeters, passive crossovers for the tweeter and mid-bass sections, and OFC speaker cables.

The RX series has been positioned above the SHX series and benefits from many solutions used in the more advanced SQ-class products from the PX series. This makes the RX-6C ECO set a good replacement for a factory audio system and a base for upgrading your car's sound system.

RX Reference Series – better sound in your everyday car

The Excursion RX-6C ECO has been designed for drivers who want to improve sound quality without building a very complicated car audio system. The set offers 120 W RMS power, 2 Ohm impedance, high efficiency of 92 dB and a frequency response of 50-21,000 Hz.

Thanks to the 2 Ohm impedance, the speakers can achieve high efficiency in many car installations. The set provides stronger bass, clearer midrange, and more detailed highs than typical factory speakers.

SX-1S tweeters – silk dome and natural treble

The Excursion SX-1S tweeters use 25 mm diameter domes made of natural silk. The diaphragm has a thin ADC anti-resonance coating, which helps reduce unwanted resonances and improves high-frequency clarity.

The drive is provided by an efficient neodymium magnet system. The OFC copper wire coil is ferrofluid-cooled, improving the tweeter's stability. The high-quality 50 cm wires are made of tinned OFC and terminated with Plug & Play connectors.

The set also includes enclosures and mounting accessories that make it easy to individually adjust the tweeter's position and angle. This allows you to better build a sound stage in your car.

RX-6M Mid-Woofers – More Powerful Bass and Clear Midrange

The Excursion RX-6M mid-woofers have a basket diameter of 165 mm. Their diaphragms are made of a lightweight and rigid 2-layer composite of natural wool and glass fiber. An additional ADC coating reduces resonances and helps achieve a cleaner sound.

A phase plug-style dust cap improves midrange resolution, even off-axis. This is important in a car, as mid-woofers often operate low in the door and at a wide angle to the listener.

The HDR Rubytec Surrounds suspension provides long, linear excursion across a wide frequency range. This allows the system to deliver more bass, better efficiency, and lower distortion. The Nomex lower suspension is handcrafted and selected.

Steel Basket, Vented Voice Coil, and 30 oz Magnet

The RX-6M mid-woofers feature a rigid, black pressed steel basket. The basket is coated with a speckled anti-resonance compound that helps reduce vibration. This design allows for free airflow behind the cone and promotes stable operation.

The magnet system utilizes a 30 oz Y35 ferrite magnet with a central vent. The 1-inch/25.9mm voice coil is wound with copper wire on a Kapton former with additional cooling holes. This allows the speaker to better handle higher power loads.

SX-HPF Crossovers for Tweeters

Two SX-HPF passive crossovers are included with the tweeters. These are first-order HPF 6 dB/oct. high-pass filters that should be connected in series in the speaker cable line.

The crossovers use high-quality MKP audio capacitors. In-Line installation is quick and convenient, and the small dimensions of 44 x 25 x 19 mm make it easy to place the crossovers in doors or under upholstery. The connectors also allow you to change the tweeter polarity.

PX-LPF Crossovers for Mid-Woofers

The set also includes two 1-way PX-LPF passive crossovers for the mid-woofers. They operate as first-order low-pass filters LPF 6 dB/oct..

The crossovers use air coils wound with 0.8 mm solid OFC wire. In-Line mounting allows for quick connection to the mid-woofer cables. This is a simple and effective solution for the RX Reference series set.

Important installation information

SX-HPF crossovers are essential for proper tweeter operation. Do not connect tweeters without filters, as this can permanently damage the voice coils. Such damage is not covered by the warranty.

Depending on the tweeter mounting location and orientation, changing the polarity may help improve response balance around the crossover point. Optional Excursion XLR attenuators can be used to lower the treble level by 2 to 10 dB.
