<br> In many cases, we will be in K room with ultra low. Because, after all, a regular 8. 10-inch box low-frequency limit is not enough, feel the bass thin! and 12 - 15-inch .wide-band box while a wide frequency response, but the frequency of thinner, singing difficult, therefore, in the room, mini K full-frequency plus ultra is the best choice. <br> So, in what K in ultra-low? .a are single-15-18, and even double 15 --- 18. Then practice, I find that there are large-sized low, <br> <br> 1. power giant, 18 low to 600w, that his power will .power 800-1000 Watt, and the General 8-10 inch box power is only 80 - 120w, the amplifier as long as 100-150w, 200w maximum per channel. In this way, the bass and full-frequency power vary considerably, .resulting in a waste of low-frequency power, at the same time, the then General K House, this high-power low-frequency component too, only a bang, not a real low permeability, the volume small, has no effect. < .br> <br> 2, bulky, placing difficult. Large diameter of ultra low volume, while the rooms area limited to the rooms of the overall design and reasonable layout difficult! <br> <br> 3, large calibre of ultra low resonance .frequency is low, in small rooms in the back to cause a resonance and a strong reflection, resulting in low frequency shouting! <br> <br> 4, large calibre of ultra low cost high, increasing the private room equipment investment. <br .> <br> After a long period of exploration and practice. I have summarized in rooms with small low experience and methods, here come up and share and explore! <br> <br> 1. use a custom low-power of 10, .12-inch single-cell active low. According to the characteristics of the rooms sound, I customized amplifier power 180w, unit to power 120w's 10-inch active low, the rooms with 120w power amplifier, and 8 inch 80w of rooms of box. .Amplifier power 200w, the unit to power 150w 12 inch active low. With 150 - 180w card package amplifier and 10-inch rooms of box. <br> <br> 2, point 10 of ultra low frequency set at 90-12 - .110HZ, ultra-low frequency point set at 80 - 100HZ. <br> <br> 3. applicable package room 25 m². Room height 12. 3-2. 8 m. <br> <br> 4, effects, low .thickness increased significantly, while fast dynamic response, permeability. Layered, chaos, by practical application! evident result better than large-diameter of ultra low. Especially when K songs. Simple volume and HI at atmosphere can also. <br>.
