Neufeldt & Kuhnke: Pioneer loudspeaker connector

03.02.2023

Loudspeaker connectorfor Pioneer amplifier / receiver SA / LX / SX

Equipment

They are suitable e.g., forLX440(A), SX727, SX525

Made in Germany, we checked each part individually!

Actually, there are no plugs to buy for the beautiful Pioneer receivers from the 1970s. Therefore, it seemed impossible to connect speakers to these receivers with a commercially available solution. So we decided to completely redesign the plug. A 4 x 1.5 mm thick copper rails provided the positive pole, and a 6.3 x 1.5 mm copper rail the negative pole. So we have enough material to adequately supply even thick cables. Thus, we designed the plugs that you can use up to 6 mm² cables.

Product features

• Separate colors (red for right speaker, blue for left)
• Plus and minus engraved on the plug with a recess
• We made the plug environmentally friendly with using PLA.
• Solid brass screws
• Thick copper rails for good sound and low resistance
• Made in Kiel (Germany)
• We tested every single connector for fit on our Pioneer LX440.

Furthermore, the housing of the LSLX-1 is produced here in Kiel on a Renkforce RF-100 3D printer. We cut the copper rails, deburred and hammered in on site. Our screws come from the local dealer, just a few kilometers away. Due to the way it is manufactured, the connector has a rough surface that is usual for 3D printing; this is production-related and cannot be changed at first.

Updatesfurther improvements

In the picture, you can see the plugs again in comparison.

There are 4 months between the old version and the new one of the Neufeldt and Kuhnke LSLX-1 Version 2. We were able to solve numerous production problems. In addition, the PLA for the left connector has been changed from blue to anthracite. This has less to do with the color and more to do with the fact that the dark PLA is of better quality. After all, the first customer from Switzerland has already received the new version. We are proud that a niche product from Germany is sold particularly often in the USA. 60% of production goes abroad. The speaker plugs for Pioneer SX, LX and SA are a real blockbuster!

Transparent versionout now

We are constantly improving and expanding our product range.

Now our popular speaker plug is also available in a transparent version made from Liqcreate's eco-friendly resin.

There is now something for every taste!
