The ETI Research offers a range of Binding Posts suitable for all speaker/amplifier types.
The ETI Research BP-20C Binding Post is a superb high-performance Binding Post available at an entry-level price. Made from 1100 Series Hardened Copper with an IAC Rating of 102%. You can rest assured the audio signal is not being degraded by having to go through a poorly conductive material such as Brass.

Copper is far superior to Brass in terms of conductivity and as such the BP-20C offers a level of audio signal quality unsurpassed in similarly priced competitor products. If you want a binding post representing outstanding value for money, this is it.
The BP-20C has a Gold Plating applied without any nickel. Many manufacturers apply a nickel surface coating before the Gold Plating as this makes the Gold look shiny. The unfortunate problem is Nickel is a poor conductor and will degrade the Audio Signal!
The Housing is made with Aluminum over a Polymer compound. The Polymer threads onto the Post so as to not have any conductive material touching the Pure Copper. The Aluminum is great at rejecting EM/RF noise that is so prevalent nowadays.
Also, you have the choice of securing the wire by either screw or solder. The Post length is 20mm, which is the preferred length for Chassis mounts or in certain Speaker Back Plates.
The Nut used to secure the BP-20C is made from a high-density non-conductive Polymer, so no conductive material touches the Copper Post, except what is needed to transfer the Audio signal.
The ETI Research BP-50C Binding Post is a very high-performance Binding Post at an entry-level price. Made from 1100 series Hardened Copper with an IAC Rating of 102% you can be assured the audio signal is not being degraded having to go through a poorly conductive material such as Brass.

ETI Research has spent countless hours developing and fine-tuning the BP-50C to ensure audio quality does not suffer in any way as it passes through the connector. With exceptionally high quality-assurance standards at an affordable price and the availability to be ordered in bulk, the BP-50C is the perfect high-quality loudspeaker Binding Post as it has a length of 50mm.
The Housing is made with a Aluminum over a Polymer compound. The Polymer threads onto the Post as to not have any conductive material touching the Pure Copper. The Aluminum is great at rejecting EM/RF noise that is so prevalent now days.

The ETI Research Kryo Binding Post is like no other on the market today. The conductor is made from Silver Plated Tellurium Copper for not only superior conductivity but long-lasting durability.

Special attention has been made to wall thickness to allow enough mass for the high current demands necessary in many speaker designs. We have also taken enough unneeded mass away to allow minimum capacitance and resistance. We firmly believe that this is the finest Binding Post you can buy.
The housing is made from Brass for superior vibration damping and high EMI/RF noise rejection. Due to the unique design, and unlike most Binding Posts on the market, you only need finger pressure to hold a Spade in place. No more having to apply excessive force in the hope that the Spade does not fall out!
This combination of high-quality materials and precision manufacturing all adds up to a superior range of audio connectors designed for use by amplifier and speaker manufacturers. The Kryo Binding Post sets the gold standard for vibration damping and noise rejection while providing outstanding conductivity and flawless performance year after year.
The ETI Research Kryo Binding Post’s innovations and refinements include:
Due to the unique design of the Kryo Binding Post, only finger pressure is needed to hold a Spade tight without it dropping out which is so common in most binding posts.
