ERSE manufactures the finest audio coils in the world today! This is evident in the fine “Q” series of coils listed on the right that we manufacture for the world’s finest quality speaker manufacturers. This is a bold statement, but with our 42 years of experience we are confident that you will not find a better audio coil anywhere.
Quality coils begin with quality components. All of our “Q” series offer our PURITY GUARANTEE. This states that we will not manufacture any “Q” series coils unless the wire meets 99.99% pure copper and meets the criteria of oxygen free. Our wire is made from CDA 101 copper cathode. This is our guarantee.
Stacked against our competitors, ERSE stands out as the best. During a recent sampling we sent our coils and some of our competitor’s coils to an independent metallurgic lab for a review of copper purity. Not to our surprise our standards met the CDA 101 requirement mentioned above, but to our surprise one of our competitors in Denmark had only a purity level of 97.9% and other European competitors had purity levels of 99.1%. This low purity creates the weakest link in your sound system.
ERSE’s pursuit audio perfection continues with quality ferromagnetic materials. We use only the world’s finest quality ferromagnetic material in our “cored” coils while most of our competitors are using typical silicon 29 gauge silicon steel.
ERSE’s only sources the finest grades of micro thin (32 gauge) grain oriented silicon steel come from Japan. This level of quality provides higher saturation levels lower eddy currents and very low THD. Take a THD Test Drive on our Super Q, and IXQ coils today and compare for yourself.
Quality second to none at a sensible price, that’s the ERSE philosophy! This is where ERSE’s 42 years of combined experience and knowledge really sets us ahead of all of our competitors. All of our “Q” series of coils are wound with orthocyclic computerized coil winders with feedback hysteresis tension devices.
This high tech equipment allows for precision layering control to .0003” tolerance. The hysteresis tension control allows for precise tension control of the wire while under winding. The precision tension control allows us to insure that we do not stretch or harm the crystalline structure of the copper cells within the wire. Every single coil is exactly the same due our precise layering control and hysteresis tension.
So if you are looking for the best coils on the planet look no further than ERSE’s “Q” series of coils.
