我们平时常说的全频喇叭(音箱),严格来说应该叫做“宽频喇叭”(全音域20~20kz的下限恐难达到)。
素质低的全频喇叭我们不去说它,因为这里是HIFI论坛。
我觉得,一个能满足交响乐重播的全频喇叭(音箱),频响宽度应该要达到45~20KHz,这是基本素质之一,也是最重要的。
全频玩得好,其他都不要~(全频高手论调)
其他基本素质还有很多!!!
对全频有兴趣的烧友和有经验的老师们,你们怎么看???

声压必须满足现场那麽大的声压,100分贝以上是必须的。

好[s:20]
老蒋兄说得好,声压必须能满足100dB以上,并保持2%以下失真度。

一个字“快”,要“快”就要盘轻,磁体够强大,其他的就是吹水用的!{:soso_e112:}

个人觉得如果玩全频喇叭,还是放弃听大制作交响乐的想法,不是一个思路。

RAIN-1000兄好[s:21]
“快”,就是速度。
大体积,永不退磁的磁体,保证速度能量的需要!
盆要轻(是否位移还要小?),打锣的铜盆肯定不行[s:97]

terencet兄好
这些数据看似不错。
但频响全音域指标,我想只有在+-3dB以上才可能实现。
我这样理解不知是否正确?
还有就是Q值指标,是否也同样是关系到全频喇叭的素质?

45~20KHz的全频喇叭比比皆是,如果不使用均衡器,45~20KHz(+-3DB)的全频喇叭还未出世。

能放好交响的全频,一是频宽,二是动态,三是全频的清晰度。据说FOSTEX的F200A具有重放交响的能力,但没听过不好说

我估计只有美国战神十二寸全频能担当此任。

去年美国权威音响杂志的评选:

This is really weird. Our overall Product of the Year is a loudspeaker—but it's not our Loudspeaker of the Year, the Magico Q5. It's not the Vivid B1 or the Sony SS-AR1 or the B&W 800 Diamond—all worthy candidates. It's not even the Wilson Sophia 3. The 2011 Overall Product of the Year is the Voxativ Ampeggio, an unconventional, single-driver speaker designed in part by the German piano manufacturer Schimmel and distributed in the US by Audioarts, a very young, very small, appointment-only audio salon in Manhattan. What the hell?
Before we try to understand how this could have happened, let's take a look at the Ampeggio itself. This distinctly gorgeous loudspeaker uses a single proprietary 7" dual-cone driver with a large, convex surround, designed to accommodate a much greater excursion than the typical Lowther driver. The complex cabinet, designed and voiced in collaboration with Schimmel Pianos, incorporates a series of faceted internal boards for optimal radiation resistance, and houses a twice-folded horn nearly 9' long.

Last spring, I accompanied Art Dudley on a brief visit to Audioarts to listen to the Voxativ Ampeggios. Had you told me then that this strange, humpbacked speaker would be our Product of the Year, I would have considered you crazy. In the small listening room, the Ampeggios sounded okay at best: Though they had an uncommonly smooth midrange, they lacked spatial depth and image specificity, and offered little to no low-end impact. But Art heard something in the Ampeggio that I simply missed. He heard its potential, he heard its heart. He got up from his listening seat, walked over to one speaker, crouched low, gently caressed that lovely driver, and requested a pair of review samples.

Art's brave, I thought.

Weeks later, the word from Art was that it had taken quite a bit of work to position the Voxativs for optimal bass response, bass extension, and treble response, but once that was done, the speakers sounded . . . superb. They offered the typical Lowther traits of transient speed, spatial presence, dramatic ease, and physical impact, but added deep, well-controlled bass and excellent soundstaging. I was surprised. John Atkinson made a trip up to Art's place, in Cherry Valley, New York, and returned with a similar report. While JA was also impressed by the Ampeggio's sound, he raved about the speaker's superbly flat in-room response and genuine 98dB sensitivity. What the hell?

Weeks later, I got to hear the Ampeggios again, this time at the Atlanta AXPONA show. Carefully positioned in a room that was usefully large but far from ideal, the Ampeggios sounded sweet, relaxed, and dynamic. I could have stayed and listened forever. Finally, I heard what Art had heard all along. From his review: "The Voxativ Ampeggio went beyond sounding good: More than once, with too many records to mention, I found myself stopping to marvel at its brilliantly good pitch certainty. . . . And while it's one thing to focus on such a characteristic for a moment at a time, it's quite another to bask in it subconsciously—and the Voxativs allowed me to do just that. I was able to enjoy everything I played through them—not just as sound but as music—without fatigue, frustration, or, worst of all, lack of interest."

Clearly, the Voxativ Ampeggio fuels our passion for music. And with that in mind, it really should come as no surprise that this strange new speaker is our Product of the Year for 2011. In its design, appearance, and sound, the Voxativ Ampeggio is bold, beautiful, distinct, and fun—a product to admire, love, and honor. Congratulations, Voxativ—and thanks.
