The technology allows Spinbase to be placed directly underneath your turntable, serving as both an elegant platform and wide-range loudspeaker system." - Andover Audio ISOGROOVE TECHNOLOGY EXPLAINED IsoGroove uses (3) main technologies in combination. It was developed by a team that developed components for Cambridge SoundWorks, A/D/S and JBL. The first and most significant is the speakers are arrayed such that the basic mechanical vibrations cancel each other. The surface was analyzed for vibration patterns. Strategically placed bracing minimize the vibrations even further. Lastly, a DSP (digital signal processor) is utilized at low frequencies to ensure that low frequencies are always balanced to provide maximum vibration cancellation regardless of musical content. 🔑 KEY FEATURES speaker type: active speaker for everyday listening peak power output: 70W frequency response: 60 Hz - 20 kHz high frequency driver: 3/4" soft dome low frequency driver: 1.75" x 4" oval woofer EQ: 2-band (high + low) wired inputs: 3.5mm line, RCA phono + ground, Optical (TOSLINK), USB Type-A wireless inputs: Bluetooth outputs: Subwoofer phono preamp: yes headphone output: yes, 3.5mm line subwoofer out: yes, 3.5mm dimensions: 18.0" (w) x 3.25" (h) x 13.5" (d) / 45.7 x 8.3 x 34.3cm weight (total): 11.0 lb / 5.0 kg 📦 COMES WITH remote control RCA cable + ground
