I love this, just no real need for it any more. Paired it with a fostex 6301B as a standalone mono monitor. Really puchy for its size.Comes with power cableFull DescriptionPowerful low-end sound reproductionThe Fostex PM-SUBmini 2 is the perfect companion for Fostex active studio monitors, providing powerful low-end sound reproduction to create a full monitoring system. The high-end sound reproduction is thanks to the internal amplifier providing 50W of power in total. As well as the integrated control panel, the subwoofer features a stand-by function which reduces unnecessary power consumption. The compact size makes it ideal for beginners and professionals, from your home studio to making music on the go.FeaturesCompact yet powerful subwoofer – ideal for use with PM0.3 or PM0.1 studio monitorsHigh-powered onboard 50W amplifierRear panel control panel with volume, crossover frequency and phase controlsPerfect of mixing and mastering applications, allowing you to capture the power of your low-end soundRigid fibreglass diaphragm for long lifespanSealed cabinet designed to optimise incidental soundStandby function to reduce unwanted power consumptionSpecificationsSpeaker Type: Sealed typeImpedance Woofer: 4 ohmsAmplifier Maximum Output: 50 WInput: RCA pin jack × 1Maximum Input Level: +15 dBV Input impedance: 10 k ohmsCrossover Adjustment Range: 60 Hz to 150 HzFrequency Response: 40 Hz to 150 HzS/N Ratio: 80 dBExternal Dimensions (mm): 200 (W) × 185 (H) × 233 (D)Weight: approx. 3.6 kgPower Consumption:During normal use: about 15During standby mode: 0.5 W or lessProduct Code: PM-SUBmini 2
At USD183 with just the power cable, this Fostex PM-SUBmini2 asking price feels ambitious for the used market. These compact 50W sealed subs typically trade hands in solid shape for USD100-150, depending on cosmetic wear and full accessory kit—new ones retailed around USD200 back in the day, so expect deeper discounts on flips without extras.
Before biting, verify the amp powers up cleanly with no hum, buzz, or distortion, as the Class-D module can falter after years of desk duty. Check the 5-inch woofer cone for tears or foam rot, and confirm the RCA input, crossover/phase knobs, and auto-standby all function—ideally test with your mains for tight 40Hz extension.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Fostex emerged in 1973 as the branded consumer and professional division of Foster Electric Co., Ltd., a Japanese loudspeaker manufacturer founded in 1949. Established to bring Foster's high-quality speaker components directly to dealers and customers, Fostex quickly gained international recognition through innovative products like the T20RP headphones and 6301 studio monitors. The brand's foundation rests on Foster's position as one of the world's largest OEM loudspeaker developers, employing tens of thousands across multiple countries and manufacturing millions of speaker units monthly.
The company built its reputation across three interconnected product categories: professional studio equipment, consumer headphones, and powered monitor speakers. Fostex became particularly renowned for pioneering RP (Regular Phase) technology, which delivers clear sound with high sensitivity and wide dynamic range—a signature that defines their headphones, microphones, and speaker designs. Beginning in 1978, the brand expanded into professional speaker development, eventually introducing the PM series of powered monitors and establishing itself as a trusted choice for recording studios, broadcast facilities, and serious home listeners.
Fostex occupies a distinctive middle ground in the audio market: neither ultra-premium boutique nor mass-market consumer, but rather a respected specialist brand with deep professional credentials. Their products appeal to recording engineers, studio owners, and discerning hi-fi enthusiasts who prioritize accuracy and reliability over luxury positioning. The 6301B monitor remains an industry standard after decades in production, while the T20RP headphones maintain popularity among studio professionals—testament to Fostex's enduring reputation for sonic integrity and engineering excellence.
