⑥. Sound-absorbing hollow space
⑦. Brief circuit copper ring
⑧.T iron
⑨. Impartial vibration hollow space
The imported silk edge + high-grade ceramic composite movie now not handiest has the nice and cozy sound of the silk movie, but in addition solves the overall drawback of treble and ultra-low and dim sound. This subject material generally seems on high-end tweeters.
The fast-circuit copper ring means is to put a copper or aluminum short-circuit ring at the outer diameter of the magnetic column or the interior diameter of the magnet.
The function of the secondary coil of the voice coil, because of the short-circuit impact, the voice coil inductance is on the subject of 0, and the short-circuit ring makes the non-linear inductance of the magnetic subject material trade small, thereby decreasing the distortion of the speaker!
Impartial acoustic hollow space + high-density sound-absorbing cotton can successfully get rid of the a couple of harmonics generated within the sound movie throughout the high-frequency vibration. The second one enhanced reinforcement penetrates the sound movie and spreads to the human ear. The extra the sound can be heard, the extra taste!
Clear, transparent, excessive sensitivity, solid magnetic box, decreasing distortion, bettering sound high quality, getting rid of a couple of harmonics, and no colour interference

Outwardly they look decent, the resistance of both is the same, the pressure is 2-3 dB too high, but these are preliminary measurements, I will drive, make more accurate measurements, and let’s see how they deal with other speakers. If it is bad, I will add feedback

Decent construction. Missing foam in pole piece, insufficient damping in rear chamber, minimal copper in short circuit ring, triple impedance peaks in impedance response. Cost isn’t too high, though, so not a total loss.
