IWISTAO HIFI 12 Inches Bass Speaker Plus Tweeter Horn Empty Cabinet Solid Wood Inverted
This speaker cabinet is 2 ways HIFI empty speaker cabinet, and made of solid wood. The bass is for 12 inches woofer unit, and the tremble is for 1 inch horn tweeter unit and it is made as wooden horn structure.
The horn is a stable hyperboloid diffusion one, and its horizontal radiation is 90 degrees, and the cutoff frequency is Fc=900hz. It is recommended that the crossover point be about 1.8K HZ.
The adapter of horn has a round-to-square smooth transition. The throat size of the transfer horn is 1 inch (25.4 mm) as default.
Built-in a invertd structure, it can enhance the low-frequency radiant energy, make low-frequency dive deeper, 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.
