The demo video for IWISTAO 3-4 Inch Full Range Empty Speaker Cabinet Labyrinth Solid Wood Strengthening Bolts Inside
This speaker cabinet is made of solid wood with strengthening bolts inside. 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.
IWISTAO Single-ended Tube Amplifier 2X3.5W Class A 6N1 Drive 6P14 5Z4P Rectifier Scaffolding Soldering Solid Wood Casing AC115/220V
The song is Bury The Heart, from CD Player + IWISTAO P14 Single-ended Tube Amplifier + 4 inch Full Range Solid Wood Speaker .
Here, 6p14 is a commonly power output vacuum tube in the previous tube radios, with a gorgeous sound and mellow sound! Savor carefully, nostalgic thoughts emerge spontaneously. This unit is suitable for high-sensitivity small bookshelf speakers, and also very suitable for using as desktop audio and upgrade computer audio.
Since the tubes of all levels are working in Class A amplification, the distortion is small, its tone is sweet and soft.Its rated output power is 2x3.5w, but the actual undistorted output power is equivalent to 2x20w transistor power amplifier because the tube has the advantage of strong overload capability,
The casing is made of Sapele solid wood, which is medium-hardness wood that maintains original color and texture of the wood. The case is coated with environmentally friendly varnish and polished and painted many times. The texture is rich, simple and beautiful! The upper and lower top plates are painted iron plates. The advantage of using iron top and bottom plates relative to aluminum plates is that they can isolate some clutter interference. Flat proportional size, solid and steady, restrained in atmosphere. There is still space inside the casing, you can replace a larger oil-immersed capacitor, or it is convenient to rub the circuit!
IWISTAO HIFI 3 Inch Full Range Speaker Finished 1 Pair Solid Wood Labyrinth Structure for Tube Amp
This speaker cabinet is made of solid wood. 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.
Its magnetic circuit system adopts the neodymium iron boron rare earth strong magnetic structure plus short circuit copper bushing, which improves its performance of music details from starting point. The choice of the cone is more exhaustive, when it is determined to use aluminum as its sound basin, it begins to this thin aluminum material has been studied in various ways. If it is thicker, its rigidity will be better, but its resolution is poorer, in contrast if it is thinner, the resolution is better, but its rigidity will be poorer. Finally, it was decided to use a thin aluminum to improve the rigidity from the shape and depth anodizing treatment. The aluminum treated in this process is almost the same as ceramic. So, the sound quality is also going to a new level, whether it is bandwidth, details and transients have an ideal performance!
IWISTAO HIFI Labyrinth 4.5 Inch Full Range Empty Speaker Cabinet Solid Wood 15mm Thickness Board
This is a labyrinth empty enclosure that is made of poplar plywood or solid wood, the veneer of poplar plywood has natural tree branches texture and wood knots and has a natural beauty,
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.
