The Nichicon MUSE ES series aluminum electrolytic capacitors used in this product are bipolar audio-grade components with little individual variation and are "Made in Japan" as stated. Components with low internal resistance are connected with lead-free solder to eliminate contact resistance. Please check the cutoff frequency in the photos. Can also be used with BLAM full-range speakers such as LFR 52 and LFR 80. Especially for 80mm speakers, the original product does not include a network, and by using this product, you can easily build a 2-way system with a passive network. BLAM midrange speakers like the LM 80 and general squawkers naturally attenuate the high frequencies from around 10kHz. It's easier to use than a bandpass filter, and the simpler electronic devices involved reduce the loss due to voltage division resistance, which also helps maintain the amplifier's damping factor. If you are using a 3-way system, we are also considering offering a network wiring using 3.3μF to cut off the tweeter at 10kHz or higher. It is planned to be 1,580 yen per pair, but please feel free to contact us if you need it. ■Caution This product has a large capacitance and cannot be used for tweeters. It is for cone-type midrange speakers and full-range speakers. Please use at your own risk. ■About Connections Since it is non-polar, either direction is correct. Normally, the wire with the text is +, and the side without the text is -. ■Request Please refer to the speaker specifications when using this product and make your own judgment. This is a handmade product, so please refrain from purchasing if you are overly concerned about minor details.
