IWISTAO Blog is the official platform of IWISTAO HIFI MINIMART, dedicated to high-fidelity audio and DIY electronics. We focus on tube amplifiers, output and power transformers, speaker enclosures, and Bluetooth audio technologies, including HiFi Bluetooth speakers, headphones, and tube-based acoustic systems. The blog shares product insights, technical knowledge, and practical guides for audiophiles and audio builders worldwide.
IWISTAO Long 4 inch Supper Tweeter 1 Pair Copper Horn Brass horns Neodymium Copper Film 6Ω 30W 625HZ-40kHz
This super tweeter is made of brass integrated stretching for musical instruments. The curve of horn is a natural and smooth parabola with a horn design and good sound field positioning. The driver unit uses a 70mm diameter neodymium copper film one with a copper short-circuit ring, a high-permeability liquid, and an ultra-lightweight 40mm diaphragm made of beryllium copper to ensure that vibration quality is lighter and more air can be pushed at the same time. Makes the music spiritual and the details more real.
The drive is a powerful magnetic circuit composed of 8 rare earth neodymium magnets. There is a 0.15mm copper short-circuit ring at the T iron position, which can obviously eliminate the influence of the voice coil inductive reactance and suppress the increase of the voice coil inductive reactance with frequency. Improve high-frequency radiation and reduce distortion.
The voice coil is filled with a cooled and highly permeable imported magnetic fluid with damping and positioning effects. Magneto-fluid has a great influence on the audio curve. It not only cools the voice coil, but also has sealing performance. A good magneto-fluid plays a decisive role in smooth sound at high frequencies. The ring reciprocates in the magneto-fluid, and the magneto-fluid plays the role of automatic centering, which greatly changes the internal resistance of the horn, especially the air sensation of the sound, and the burr sensation of the speaker without the magneto-fluid is obvious in comparison.
This version is that Crystal binding post is fixed if you don't need connect it to a professional crossover. You can use this one connect with your full range or bass speaker directly in parallel.

IWISTAO 3-4 Inch Full Range Empty Speaker Cabinet Labyrinth Solid Wood Strengthening Bolts Inside for Tube Amp
This speaker cabinet is made of solid wood with strengthening bolts inside, suitable for 4-inch and 3-inch full-range speakers.
Built-in a labyrinth structure, it can enhance the low-frequency radiant energy, make low-frequency dive deeper, effectively overcoming insufficient bass of commend full range speaker cabinet, make the speaker cabinet the full-frequency be more full and rich.
As you know, the greater the material density of the speaker enclosure, the less the vibration produced by the enclosure. Solid wood is more reflective of sound than other materials, and tightness of the wood is higher, and the sound can be effectively expressed by the vibration of the air inside the box. We often say that the sound of wooden speakers is warm, in fact, the word warm means the balance of tri-band that are low, medium and high frequency; if the frequency is too low or too high, it will make people feel uncomfortable. The advantage of wooden speaker is that its playback effect is good, the vibration of the sound inside the box is stable, and the sound effect will be balanced and full.
The tube amplifier is used vacuum tube 6P14 as power amplifier.
