Passive Speaker Attenuator for Low to Mid Wattage Tube Amplifiers

2,4,8 and 16 Ohm versions available

The Kingfisher was built on the success of the Tweedy Bird and Black Bird attenuators with the low to mid wattage amplifier in mind. The color of the Kingfisher will fit right in with fans of the AD30, OR15, TH30, Rocker 32, Dual Dark 50, and Custom Shop 50 amplifiers from one of the legendary British valve amp kings! The Kingfisher is the same quality build as the Tweedy and Black Bird but housed in a plain painted orange enclosure without the tweed or tolex covering.

Detailed attention to the preservation of high frequencies, at low volumes, was the key focus of my design. Many hours of design/research and testing have yielded fantastic results! Even at the lowest volume settings, (90db typical at speaker), most of the high frequency content stays intact. There are no switches to flip or buttons to push. Simply plug the output from your amplifier into the Amp in and your speaker into the speaker out and dial in the volume you are looking for. A true bedroom volume practice amp from your stage rig!

Now, to move on from my sales pitch, let’s talk reality. This is a PASSIVE / Non-Reactive speaker attenuator! At anything other than wide open, 100% volume, speaker is not a true reactive load on the amplifier. That being said, ANY passive speaker attenuator will never sound and feel as good as an active attenuator with a reactive load (i.e… Weber Mass/Mini MASS). Especially at critical recording volumes in the 100db – 115db (at Speaker) volumes. While my passive attenuator does sound fantastic at these volumes, simple things like feedback from the amplifier does not propagate as it would without a static/passive load between the amp and speaker.

While the passive load is rated at 100W RMS/200W Peak (8/16 Ohm), 125W RMS/250W Peak (2/4 Ohm), I do not recommend use at high attenuation levels and extended periods of time with Amplifiers over 65 Watts (8/16 Ohm), and 85 Watts (2/4 Ohm). This allows for some headroom for sufficient cooling and component longevity. With all of this being said, if you are looking for the perfect low volume recording situation for your current stage rig, I would spend the $200+ on a Weber Reactive load attenuator. The Physics behind Ted’s design is solid and well worth the $$ they garner. However, if you are looking for the BEST sounding passive attenuator for low volume practice/rehearsal and writing/recording demo tracks, or to tame your stage volume, look no further!

Included: Rubber Feet



WARNING: Because the Kingfisher does not have the Tweed or Tolex covering it will be HOT to the touch after long and/or heavy attenuation. Allow unit to cool before disconnecting or moving.

Disclaimer: The Kingfisher must be connected between the amp and speaker using the proper jacks (i.e… Amp jack goes to Amplifier Output and Speaker jack goes to the Speaker). While holding the Kingfisher with the volume knob facing you and the jacks toward the top, the amp input is to the left and the speaker output to the right. Connecting the Kingfisher in reverse can seriously damage your Amplifiers output transformer! DON’T DO IT! I will not accept responsibility for any damage associated with not following the included instruction for safe and reliable use. YOU HAVE BEEN WARNED!
