PHD Audio RED6.1C

PHD Audio Red 6.5 Coaxial Speakers - Designed & Made in Italy

Overview

PHD Audio RED 6.5 Inch Coaxial Speakers feature a 6.5” midrange with 1” tweeter.

To enable accurate bass and mid-range sound reproduction, a sturdy body is required with an opening at the back that interferes with the movement of the cone as little as possible. PHD Audio's own production composite casting frame has been made as open as possible whilst remaining sturdy. The connections brought through the frame leave the air holes open and do not disturb the air flow on the back side of the element.

Are you tired of the speaker connectors always being the "wrong size" and not having the right connectors for them? All PHD Audio coaxials, midbass, midrange drivers and widebands use beefier connectors. Both the plus and minus connections are standard-sized 6.3 x 0.8 mm flat connectors. A good quality abiko or würth flat connector grips the terminal properly and ensures a good contact. The element's gold-plated cable connections are attached through the frame, so the terminal's attachment to the element is also sturdy.

The upper suspension is HBNR rubber (Hydrogenated Nitrile Rubber). As in all PHD Audio speaker elements. The material is one of the most valuable types of rubber, but it has excellent properties specifically for hanging the speaker. Mechanical resistance, abrasion resistance, chemical resistance, flexibility and temperature resistance (-40 – +160 °) are all at an excellent level.

For ventilation of the voice coil, there is a ventilation opening in the center pole of the magnet. The cone is a fiberglass cone to which other fibers have been added to strengthen the cone and eliminate cone resonance. The lower suspension is a linear suspension.

In all PHD Audio coaxials, midranges, widebands and midbass, the design of the frame also includes consideration of installation. The fixing screws do not come on top of the suspension, but the location of the fixing holes is such that the speaker can be easily fixed with reasonably sized screws.
