Special design precisely focuses magnetic flux without leakage.\u003c\/li\u003e\n\u003cli\u003eFelt dampener to control and reduce tweeter dome resonance.\u003c\/li\u003e\n\u003cli\u003eWide 25mm lightweight aluminum voice coil with Cu-Al coating – significantly extends bandwidth.\u003c\/li\u003e\n\u003cli\u003eResin-impregnated silk dome with integrated suspension – one-piece construction, reduces weight, and allows for extremely high-frequency reproduction. Absence of joints prevents resonance phenomena.\u003c\/li\u003e\n\u003cli\u003eCNC-machined aluminum flange – midrange and tweeter are screw-mounted, both can be replaced if needed.\u003c\/li\u003e\n\u003cli\u003eIntegrated connector between midrange and tweeter – pure gold-plated copper, accepts thick cables, secured with Allen screws.\u003c\/li\u003e\n\u003cli\u003eTCA system controls the airflow of the midrange cone – aperiodic damping ensures fast and controlled energy release without persistent oscillations.\u003c\/li\u003e\n\u003cli\u003eDie-cast and powder-coated aluminum frame (midrange) – minimal airflow resistance, FEM-optimized shape reduces vibration and resonance.\u003c\/li\u003e\n\u003cli\u003eWide lightweight Nomex voice coil with aluminum winding – significantly extends midrange bandwidth.\u003c\/li\u003e\n\u003cli\u003eLarge balanced Conex™ spider – ensures linear movement in both directions and reduces distortion.\u003c\/li\u003e\n\u003cli\u003eVoice coil and cone connection collar – distributes pressure over a wide area, reducing deformation and distortion.\u003c\/li\u003e\n\u003cli\u003eCone made from high-modulus carbon fiber using vacuum and autoclave pressing – rare and expensive technology, but offers exceptionally natural reproduction and high dynamics in transients. One-piece without a dust cap – excellent dispersion and flat frequency response at the top end.\u003c\/li\u003e\n\u003cli\u003eNBL rubber surround – shape designed to ensure very smooth movement at small amplitudes, becoming more controlled as amplitude increases. Makes the speaker very dynamic and powerful.\u003c\/li\u003e\n\u003cli\u003eCNC-machined aluminum protective grille.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNominal Impedance: 4 ohms\u003c\/li\u003e\n\u003cli\u003eRated Power (RMS): 110 W\u003c\/li\u003e\n\u003cli\u003eTransient Power: 220 W\u003c\/li\u003e\n\u003cli\u003eFrequency Response: 130 Hz – 25 kHz\u003c\/li\u003e\n\u003cli\u003eSensitivity: 91.5 dB (tweeter) \/ 90.8 dB (midrange) (2.83V\/1m)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ESB Audio","offers":[{"title":"Default Title","offer_id":56759777132919,"sku":"9.UMA","price":1999.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0989\/5159\/4359\/files\/9.UMA_1.jpg?v=1771440162","url":"https:\/\/hifikaupat.fi\/en\/products\/esb-audio-9-uma","provider":"Hifikaupat.fi ","version":"1.0","type":"link"}
