2 Stück = ein Paar Mundorf AMT 25 Air Motion Hochtöner Lautsprecher in silber original verpacktGebraucht (waren zu Testzwecken in Gehäuse eingebaut aber sonst nicht in Betrieb), aber voll funktionsfähigIn den Senken der Schraubenlöcher Abdrücke von den Schrauben zu sehen, wenn in der Lautsprecherfront verschraubt, ist davon natürlich nichts mehr zu sehenFrontplatten noch mit blauer Schutzfolie abgedecktDas Lautsprecherprojekt ist inzwischen eingestellt.......Zu schade zum Rumliegen6,8 Ohm Gleichstromwiderstand (8 Ohm Impedanz)Seriennummer 30044 und 30045Mundorf Logo auf Frontplatte eingeprägt Eine Befestigungsschraube fehlt, sollte leicht zu ersetzen sein

One pair of Mundorf AMT21CM2.1-C Tweeters. Many new speaker designs are using AMT/Mundorf tweeters because they are excellent tweeters! They have two of the most important tweeter attributes - wide, flat frequency response and high sensitivity. The frequency response is 2.5kHz to well over 20kHZ. Sensitivity is rated at 92 to 93dB. See the red line in the frequency response graph in photo #3. These tweeters are in very good cosmetic condition and perfect operating condition. These tweeters sell for $1068/pair at Madisound (note the Madisound price listed is for ONE tweeter). My price is well less than half of that. I will ship these USPS Priority Mail. They will be expertly packed for safe arrival. Thanks!

Mundorf AMT21CM2.1-C Air Motion Tweeter (AMT) Pair. Good condition. Tweeters are in perfect working order. Used briefly in a pair of DIY desktop speakers. Mostly they have sat unused. Just ran a DATS sweep on them and they are good to go!

DIY Point-to-point to high-end standards EL84 integrated amplifier One triode per channel in preamplifier section (mirror-connected, when the triodes end their life cycle, you swap them and you have the second triode of each ECC88/6n1p/6n23p/6n6p double triode working)EL84 in power section, pentode connected Amplifier schematic is inspired by Decware, RH84, Emission Lab (for power supply section) with some of my ideas and a lot of testing during one and a half year of development.For any section of the amplifier there were multiple high end parts tested to find the best sound possible.
