Infinity Reference Box Features :

Vented polepieces - Additional cooling of the motor structure is provided. The subwoofer's thermal capabilities are augmented, increasing power handling.

Progressive spider - Each Reference subwoofer features a progressive spider, which provides better control at excursion limits than a linear spider. The benefit is reduced distortion at high output levels.

Large-roll rubber surrounds - This material provides optimum cone-edge suspension and absorbs distortions that may travel up the cone edge. The benefit is reduced distortion.

High rigid MDF enclosure with black vinyl finish - this elegant cabinet prevents vibrations and features engraved Infinity logos on its lacquered side panels.

Custom tuned bass reflex system with proprietary port acoustically optimized for the in-car environment for tight and deep bass response. The double-flared port eliminates mechanical noises created by excessive turbulence at the mouth of the vent. The large vent diameter reduces suspension losses for better low-frequency reproduction.

In Phase IPA500 Features :

In Phase amplifiers have been designed to appeal to both the power enthusiast customer and also the discreet upgrade customer. Starting on the outside, all amplifiers in the range feature a stunning black crackle effect metal casing along with matching screw on end caps for a fantastic install.

The amplifiers feature an ultra bright LED to denote power and protection modes. In normal use a cool blue glow will be emitted from the LED.

All amplifiers have built in thermal and short circuit protection. All feature fully adjustable high and low pass filters and all except the IPA500 have variable bass boost controls. The IPA600 and IPA900 feature buffered RCA output for easy daisy chaining. The IPA1204 which gives phenomenal power into 4 channels (4x100w RMS) even has a built in silent running cooling fan. All amplifiers even feature high level input sockets to allow you to run the amplifiers from your existing factory fitted radio.

Each In Phase amplifier is hand built, and goes through 35 different checks for reliability and quality control to ensure you are buying the best for you money. We strongly believe is not a better product out there for the same price.
