Peerless Audio Mfg. - KU45MR - 9514057 - Mid-Range Speaker, 4 1/2" Square, ALNiCo Magnet

Founded in Denmark in 1926, Peerless has been delivering high-quality audio solutions ever since, and we’ve used our decades of design and manufacturing expertise to create a line of premium professional drivers and amplifier modules that deliver truly superior sound. From our FEA-optimized motor design to our Kevlar-loaded, non-pressed paper cone, each component has been thoughtfully designed to withstand the rigors of professional applications.

Speakers made with ALNiCo magnets are often raved about as the vintage-certified choice of true tone hounds. The fact that the alloy used to make them is more expensive—thanks to some of the precious metals it includes. ALNiCo speakers are made with magnets containing aluminum, nickel and cobalt.

ELECTRO CAP - 386-1059-000 - F500B305K- 3uF 100V Polypropylene Radial Capacitor

Polypropylene capacitors are designed for general purpose filtering applications. Their stability and low
loss characteristics make them an excelllent choice for blocking, filtering, bypassing, coupling and decoupling applications.

A crossover serves as a filter that blocks out unwanted frequencies to a speaker or group of speakers. This is extremely useful because it allows us to specifically send each speaker the group of frequencies that it will play most efficiently and effectively.
