KZK White Line 2pc 4.7uF 400V 5% Tweeter Filter Capacitor for Speaker Crossover

Description

KZK
White Line
- the renewed version of KZK K78-34 - High Quality Russian Audio Grade Capacitors
Brand new 2020, made in Russia
4.7uF 400VDC
±
5% Audiophile Axial Capacitors for loudspeaker crossover networks,
audio applications, tube and solid-state audio amplifiers, phono stages
MKP - metallized polypropylene film audio capacitors, soviet/ussr military based technology
400 VDC rating is excellent for crossover networks, allowing the capacitors to flawlessly handle large current peaks without distortion.
Ideal for building or repairing top quality loudspeaker crossover networks. Simply fix to the panel with hot melt glue or cable ties.
Hermetically sealed polycarbonate tubular case, axial tinned pure copper leads
Lot for 2 capacitors, precision matched couple(by de-5000 multimeter @1kHz)
particular audio design of KZK K78-34 are the result of an extensive research and development project by KZK brand(established 1958), which produces capacitors for military and oil industries;
special metallized polypropylene film with heavy Al-Zn edges for low dissipation factor and more clarity in highs;
in contrast to traditional capacitor metal end spraying with Zn+ alloy, we use only ultra-pure Zn with special grain structure in order to eliminate parasitic effects in contact areas;
proprietary electrical and thermal treatment allows to get very stable parameters of capacitors and also gives natural musical tone without any harshness of high-order harmonics;
fits for upgrade/replacement old/cheap/dried-up electrolytic/film capacitors in vintage/new factory speaker crossovers;
superior replacement for paper/wax capacitors in tube electronics; made by ISO 9001-2011 certified professional manufacturer;
capacitors undergo a 15-minute proof test to voltages 50% higher than their normal working voltage;
2 weeks break in period is recommended;
highly recommended by Tony Gee's Humble Homemade Hifi Capacitors test;
KZK K78-34 is a full bodied, slightly warmish sounding capacitor with a very smooth top end(c)
Improvments made since K78-34 version:
new polycarbonate hermetically sealed case to prevent humidty influence;
parasitic inductanсe is reduced because of updated proprietary film winding scheme;
case is entirely filled with compound in order to eliminate parasitic vibrations and resonances;
capacitor assembly is made by hands for additional quality control;
using high conductivity solder to attach the leads;
laser engraving label;
