Description: Wavecor Subwoofer SW270WA01 4 Ohm 10 Inch

Wavecor Speaker Driver - SW270WA01- 4 Ohm 10 Inch Air-Dried Paper Cone Subwoofer

Description
The 10 Inch transducer SW270WA01 was designed specifically for high performance subwoofer applications where sound quality and low distortion are the priorities. It features the Wavecor Balanced Drive motor technology.

Features

Extremely large linear stroke, Xmax = ±11 mm, ensuring low distortion at high output levels
Very rigid air dried paper cone cone to ensure piston motion at high levels for reduced distortion
Chassis with extensive venting for lower air flow speed reducing audible distortion
Vented centre pole with dual flares for reduced noise level at large cone excursions
Heavy-duty black fibre glass voice coil former to reduce mechanical losses resulting in better dynamic performance and low-level details
Large motor with 2" voice coil diameter for better control and power handling
Built-in alu field-stabilising ring for reduced distortion at high levels
Low-loss suspension (high Qm) for better reproduction of details and dynamics
Black plated motor parts for better heat transfer to the surrounding air
Conex spider for better durability under extreme conditions
Gold plated terminals to ensure long-term trouble free connection

Note 1 Measured in infinite baffle.
Note 2 Tested in free air (no cabinet).
Note 3 Measured using a semi-constant current source, nominal level 2 mA.
Note 4 Measured at 20 deg. C
Note 5 It is generally a rough simplification to assume that loudspeaker transducer voice coils exhibit the characteristics of an inductor. Instead it is a far more accurate approach to use the more advanced model often referred to as the "Wright empirical model", also used in LEAP-4 as the TSL model (www.linearx.com), involving parameters Krm, Erm, Kxm, and Exm.
Note 6 After burn-in specifications are measured 12 hours after exiting the transducer by a 20 Hz sine wave for 2 hours at level 10 VRMS. The unit is not burned in before shipping.
