Additional Details
APX 4 features a concentric coaxial tweeter: with one single point of sound emission it is possible to obtain a consistent in-phase response, with consequent reconstruction of the acoustic scene comparable to a system of separate woofer + tweeter.The 4³ cones surround features the exclusive shallow Triple Wave profile, for maximum excursion linearity.
Features
- Concentric Coaxial Tweeter: tweeter is mounted within the
woofer with one single point of emission providing consistent
phase response, with an accurate recreation of the sound stage
comparable to that of a component system. - Tweeter features an acoustic lens specifically designed to
ensure an extremely linear frequency response, even in off-axis
placement, typical of in-door installations. - 32 mm pure copper voice coil, for high power handling and
outstanding low frequency control. - Overall mounting depth optimized for OEM Integration thanks
to the concentric tweeter and the low profile basket. - Water-repellent treated paper cone, featuring a profile developed
with FEM (Finite Element Method) simulation technology and
optimized with the Klippel Scan Vibrometer. - TPU (thermoplastic polyurethane) suspension with unique “triple wave” profile for maximum linearity of excursion.
- Compact basket, protected by abrasion-resistant and scratchproof coating, the motor affixed with damping epoxy adhesive.
- High current fast-on terminal with double contact on positive
and negative poles for high flexibility and quick connection. The
terminal features a temperature resistant plastic cover,
protecting it against accidental short circuits. - Developed with the KLIPPEL suite. –

Vaccuum
Does not work well on deeper pile carpeting.
Does not have an adjustment to raise or lower the beater bar . Good on hardwood floors or tile.

Great customer service.
Glad I bought the protection. The vaccume worked great for a while then quit holding a charge. They refunded my purchase price (Amazon gift card).
