The RV3143 features three cooling systems:- in addition to a vented magnet it uses the Radial chassis, which acts as a giant heatsink, plus a multi-finned magnet intercooler. This keeps voice coil and magnet temperatures exceptionally low resulting in superb reliability, 3dB less power compression and tight, clean bass even after prolonged operation at maximum power. The RV3143 has a symmetrical field magnet with extended centre pole for absolute linearity and transient control on high power peak inputs. It has double rear suspensions for stability and a 4 layer voice coil to maximise BL.SpecificationsMounting InformationResponse CurveThiele-Small ParametersSuggested EnclosuresFactsheet PDF Model Number: RV3143 Nominal Diameter (mm): 310 Power Capacity (Watt AES): 300 Sensitivity (dB/watt/m): 91.5 Frequency Range (Hz): 29-700 Impedance (Ohms): 8 or 16 BL Factor: 18 Voice Coil Diameter (mm): 75 Voice Coil Material: Copper Maximum Excursion (mm): 30mm (before damage) Magnet Assembly Weight (Kg): 5 Effective Moving Mass (Kg): 0.076 Compliance (M/N): 0.00027 Volume Displaced (litres): 3 Connection: Metal Push Terminals Chassis: Diecast Aluminum Condition: NEW / NEVER usedPackaging damagedThe speakers have been kept in the storage for a while, so some of the magnetic frame details have some cosmetic damages, which have no impact on the overall quality of the speakers Please contact me if you have ANY questions before purchasing.
