换了中置和环绕。
昨天试了Pacific rim。
我的8“boston显跟不到节奏。

是时候了,我的Boston 8"也丢在一边了!!有目标了吗??
还没,没这样快。有的是时间。
会找些有built in mic的容易setup。
我不重口味的10“或12”就够了.gif)

够力,你的要求越来越高了。如果要找有自动调音, 不用想太多,直接上DD12+。

1)
On the Bench
I used one subwoofer for all the tests, with the microphone two meters away. Although the DXD-12012 is designed specifically to be placed in a corner, I tested it about 3 feet into the room because I have bass traps permanently mounted in all the corners. For the measurement results shown below, when the Peak Amplitude is less than 100 dB, it represents the maximum volume I could obtain before the amplifiers clipped. Undoubtedly the lack of corner placement reduced the maximum volume obtainable, so you can add 3 - 6 dB to the Peak Amplitudes less than 100 dB that would be obtainable if the subwoofer were in the corner as it is designed to be.
At 15 Hz and 90 dB output, THD+N was 8%. This is really very good for 15 Hz, but wait until you see the other graphs.

-----------------------------------------------------------------------
在板凳上
我用一个重低音扬声器的所有测试,与麦克风两米开外。虽然DXD-12012是专为放置在一个角落里,我测试了大约3英尺的房间,因为我有永久安装在所有的角落低频陷阱。对于下图所示的测量结果,当峰值为小于100分贝,这代表我可以得到放大裁剪前的最大音量。毫无疑问,缺乏角落放置减少了最大音量得到,所以你可以添加3 - 6 dB到最大振幅小于100分贝以上,这将是获得,如果低音炮是在角落里,因为它的设计是。
在15赫兹和90 dB输出,THD + N为8%。这真的是很不错的15赫兹,但等到你看到其他的图表。
-----------------------------------------------------------------------

2)
At 20 Hz and 97 dB, whoa ! ! ! Less than 1% THD+N. I watched the screen and spectrum as I dialed up the volume, and I could not hear anything as I began raising the SPL. The only indication the subwoofer was doing anything was the peak on the spectrum as it rose while I increased the volume.
-----------------------------------------------------------------------
在20赫兹和97分贝,哇!!!不到1%的THD + N少。我看着屏幕,频谱,因为我拨通了音量,而我什么都听不到,因为我开始提高声压级。低音炮是做任何事情的唯一迹象是高峰的频谱,因为它上涨,而我提高了音量。
-----------------------------------------------------------------------

3)
Try 0.7% THD+N at 25 Hz and 98 dB with most subwoofers, and you will see a similar number, but the decimal point will be moved one number to the right.
-----------------------------------------------------------------------
尝试0.7%的THD + N为25 Hz和98分贝与大多数低音炮,你会看到一个类似的数字,但小数点将被移动一个数字到右边。
-----------------------------------------------------------------------

4)
30 Hz, 101 dB, 0.6% distortion? No problem with the KREISEL. No wonder movie and music studios use this subwoofer.
----------------------------------------------------------------------- 30赫兹,101分贝0.6%的失真?没问题的KREISEL。难怪电影和音乐工作室使用这个低音炮。
-----------------------------------------------------------------------

5)
At 35 Hz, still below 1% THD+N.
-----------------------------------------------------------------------
在35赫兹,仍低于1%的THD + N。
-----------------------------------------------------------------------

6)
I was surprised to see the distortion up somewhat at 40 Hz, but the Audio Precision just tells it like it is.
-----------------------------------------------------------------------
我很惊讶地看到扭曲了几分,在40赫兹,但Audio Precision公司只是告诉它喜欢它。
-----------------------------------------------------------------------

7)
And at 50 Hz, again, the distortion approached 2%. This is still very good, but it is apparent that the DXD-12012 is optimized for the lowest octave, which is just fine with me.
If you like distortion in deep bass, this is not the subwoofer for you.
-----------------------------------------------------------------------
并且,在50赫兹,再次,该失真接近2%。这仍然是很不错的,但显而易见的是,DXD-12012是最低的八度,这只是我没问题了优化。
如果你喜欢在深沉的低音失真,这低音炮不适合你。
-----------------------------------------------------------------------

8)
The frequency response was flat enough that any modern receiver with auto room correction can easily take care of the peaks, and boost the output below 18 Hz. Just be sure to place the subwoofer in a corner as outlined in the DXD-12012 instruction manual.
----------------------------------------------------------------------- 频率响应是平坦的,以至于任何现代的接收器,支持自动空间修正可以轻松拍摄的山峰照顾,并提高低于18 Hz的输出。只是一定要放置在低音炮的一个角落作为DXD-12012说明书所述。
-----------------------------------------------------------------------

I also tried the subs in a DUO setup, where one sub sits on top of the other, but upside down, with rubber spacers in each corner to minimize sound transfer between the two enclosures. Here is where you use the Pass-Through jack. It was no surprise to see the maximum SPL jump several dB. However, I do prefer to use two subs in stereo mode rather than connecting them together in dual mono.
Here is what a DUO setup looks like.
----------------------------------------------------------------------- 我还尝试了潜艇的DUO设置,其中一个子就座于另一个的顶部,但是倒过来,用橡胶隔片在每个角上,以最小化在两个外壳之间的声音传输。在这里你使用直通插孔。这是毫不奇怪地看到的最大声压级跳几个分贝。不过,我更喜欢使用立体声模式下的两个潜艇,而不是把它们连接在一起的双单声道。
这是一个多么Duo设置的模样。

DD+12 要多少米?
自动调音比较准
对JL Audio念念不忘
