Alibaba.com offers 128 speaker phase plug products. About 47% of these are speaker, 26% are professional audio, video lighting, and 3% are electrical plugs sockets. A wide variety of speaker phase plug options are available to you, such as computer, home theatre, and mobile phone.A compression driver is a small specialized diaphragm loudspeaker which generates the sound in a horn loudspeaker. It is attached to an acoustic horn, a widening duct which serves to radiate the sound efficiently.
With phase plugs the cone separates into two halves which reduces wave cancellation at HF and lobbing as well as reducing hot spots which some FR drivers are notorious far. I don't need to argue the merits of full range driver phase plugs which is a featured component among.Metal phase plugs, as seen in some drivers (Acoustic Elegance, Creative Sound, Peerless, Seas Excel, and others) also help with heat dissipation. Eminence has applied heatsinks/phase plugs to many of its high-power woofers. One other benefit of phase plugs is to eliminate a resonant cavity in the woofer's construction. Similarly to the more commonly seen vented pole piece, the use of a phase.

Note: Beware, many loudspeaker manufacturers use a quasi phase plug which looks like a phase plug for marketing purposes, but does not physically separate from the cone of the driver.

Whilst this is physically impossible, the phase plug provides a usable compromise to this goal, and has been employed in compression drivers for quite some time. There.Trying to knock together a phase plug for the Funktion 1 Ax88 driver. according to this the principle is not complex in terms of calculations.
In a loudspeaker, a phase plug, phasing plug or acoustical transformer is a mechanical interface between a speaker driver and the audience. The phase plug extends high frequency response because it guides waves outward toward the listener rather than allowing them to interact destructively near the driver.The drivers above feature small paper-voice-coils, paper cones, re-fitted foam surrounds, spruce-phase-plugs, small magnet and small power-dissipation.
