Alpine SPS-M601
S Series Marine 6" 2-Way Coaxial Speaker - 110 Watts Peak Power - Silver Grille - Open Box
Bring reliable Alpine sound to your boat with the Alpine SPS-M601 S Series Marine 6" 2-Way Coaxial Speaker. Designed specifically for marine applications, the SPS-M601 combines a durable Poly-Mica woofer with a titanium/PEI balanced-dome tweeter to deliver clear, full-range audio while standing up to the demanding conditions found on the water.
With 35 watts RMS and 110 watts peak power handling per speaker, the SPS-M601 provides efficient performance with factory and aftermarket marine audio systems. The silver grille gives the speaker a clean, understated appearance that works well with a variety of boat interiors and exterior installations.
Marine-Ready Construction
The SPS-M601 is engineered for environments where ordinary car speakers may not be suitable. Its IPX5 water-resistant construction helps protect the speaker against water projected from different directions.
The speaker is also designed to withstand exposure to ultraviolet light, salt spray, fog, and the vibration associated with marine applications.
6.5-Inch Poly-Mica Woofer
The SPS-M601 features a 6.5-inch Poly-Mica woofer designed to deliver responsive and balanced sound.
The woofer reproduces the midbass and midrange portions of your music, helping provide body and impact to vocals, drums, guitars, keyboards, and other instruments.
Its durable rubber surround supports smooth cone movement while helping the speaker withstand the conditions associated with marine use.
Titanium/PEI Balanced-Dome Tweeter
A 7/8-inch titanium/PEI balanced-dome tweeter is integrated into the woofer assembly to reproduce high-frequency detail.
The tweeter adds clarity and definition to vocals, cymbals, acoustic instruments, and other upper-frequency content while the coaxial configuration keeps installation simple.
110 Watts Peak Power
The SPS-M601 handles 35 watts RMS and 110 watts peak power per speaker.
Its 35-watt RMS rating provides dependable continuous power handling, while the 110-watt peak rating allows the speaker to handle short-term dynamic peaks.
The 4-ohm nominal impedance allows the SPS-M601 to work with a wide range of compatible marine receivers and amplifiers.
89dB Sensitivity
With 89dB sensitivity, the SPS-M601 is designed to produce strong output without requiring excessive amplifier power.
This makes it well suited for marine systems powered directly by a factory or built-in head unit. The speaker can also be paired with an appropriately matched amplifier when additional output is desired.
50Hz-20kHz Frequency Response
The SPS-M601 provides a 50Hz-20kHz frequency response, covering a broad portion of the audible spectrum.
The 6.5-inch woofer handles the lower and midrange frequencies while the integrated tweeter reproduces the upper frequencies for a balanced full-range presentation.
Water, UV, Salt and Fog Resistant
The SPS-M601 is built to withstand the environmental conditions encountered in marine applications.
Its IPX5 rating provides water resistance, while the grille is designed for UV resistance according to ASTM D4329. The speaker is also designed to resist salt spray and fog exposure according to ASTM B117.
UV-Resistant Silver Grille
The SPS-M601 includes a silver ultra-UV-resistant grille designed for marine use.
The silver finish provides a clean appearance while the UV-resistant construction helps the grille withstand prolonged exposure to sunlight.
High-Temperature ABS Frame
A high-temperature ABS frame provides the speaker with a strong and stable mounting structure.
The frame is designed to withstand heat, vibration, and environmental exposure, making it suitable for boat and other outdoor installations.
Built-In Tweeter Protection
Alpine incorporates built-in tweeter protection into the SPS-M601 to help protect the high-frequency driver during operation.
This integrated design helps simplify installation by eliminating the need for a separate external tweeter-protection component.
Installation-Friendly Design
The SPS-M601 is designed for compatible 6.5-inch marine speaker locations, with a 5-inch mounting diameter and approximately 2-27/32-inch mounting depth.
The speaker is supplied with a silver grille. Because mounting locations vary between boats, verify the available cutout and mounting depth before installation.
Open Box Condition
This Alpine SPS-M601 is offered in Open Box condition. Open-box products may have packaging that has been opened or show signs of handling or previous inspection.
The specific cosmetic and packaging condition can vary by unit. Please review the product listing and accompanying photos for the exact condition, included accessories, and packaging supplied with this unit.
Designed for Marine Audio
The SPS-M601 provides a practical way to upgrade an existing marine audio system while maintaining the durability required for use on the water.
Its combination of Poly-Mica woofer construction, titanium/PEI tweeter technology, 89dB sensitivity, and 35-watt RMS power handling delivers an efficient balance of sound quality and output.
Alpine Sound on the Water
The Alpine SPS-M601 combines dependable Alpine audio performance with marine-focused construction. Its water-resistant design, UV-resistant silver grille, salt and fog resistance, and 2-way coaxial configuration make it an excellent choice for compatible boat audio installations.
