可以可以，顺便给你发个以前的价格，注意ls35a和ls5/12的价格，35a现在炒到两三四万，ls5/12和6a一个档次。转个介绍给你看，注意两者价格。你要确定的不是新版老板或者什么版，是要使用D260的那个版。
BBC LS3/5a loudspeaker 1977 BBC Version part 2
We were not able to determine how far out the high end goes, because our oscillator's upper limit is 20kHz, but the smoothness and the ability to reproduce hard transient information (triangles, castanets, etc.) suggested that 27kHz might not be a bad guess for the upper rolloff point. Overall, the monitors have an extraordinary feeling of depth and breadth to their sound. Inner details were excellently rendered, and there were no audible vowel-like colorations that we could detect. The only thing we could fault the Monitors on (other than the low-end range) was a subtle tendency to lighten or "stretch upward" the vowel structure of some instrumental sounds. The effect could be likened to the difference between the lower range of an oboe and the upper range of an English horn, although the extent of the difference was less. Our comments about the sound of these speakers have thus far been based on its performance with what we feel (as of this writing) to be the best available power amplifier: the Audio Research D-150. (The new Audio Research equipment has just been announced, but will not have been auditioned by the time we return our Monitors.) We freely acknowledge the idiocy of driving a $430 pair of speakers with a $2700 power amplifier, but we can report that these Rogers/BBC speakers did just as well (if not slightly better in one one respect: a less "hot" high end) when driven by a Dual 76A. It is both a tribute to, and a liability of, these speakers that the lesser their driving equipment, the worse they sound. They reproduce the high-end roughness of solid-state amplifiers mercilessly, and most such amplifiers tend also to dry up their bass end a bit so that they lose some of their nice bottom fatness. (Placing them nearer to room boundaries then helps to compensate).
Harbeth LS5/12A: $2200/pair
This tiny monitor was developed by Graham Whitehead of the BBC's Engineering Department, a team famed for its work on monitors in the '70s, and which designed the classic LS3/5a, among other loudspeakers. Sadly, to save money the BBC has axed the staff in this department, meaning that the LS5/12A might be the last loudspeaker design to come from the BBC. As with all BBC designs, however, actual manufacture is licensed to outside companies; the LS5/12A is being produced by Harbeth Acoustics, the company founded by ex-BBC engineer Dudley Harwood and now run by LS3/5A enthusiast Alan Shaw (see "Manufacturers' Comments," January 1994, p.235).
The design brief for the LS5/12A was to make a monitor loudspeaker around the same size as the LS3/5A, with a tonal balance similar to existing larger monitors, but to have a much greater dynamic range and a more extended bass than its predecessor. The result is an elegant little loudspeaker, with the front baffle almost entirely occupied by two high-quality Dynaudio drive-units compared with the '3/5A's KEF units. The 1" soft-dome tweeter is an expensive Esotec unit, the D-260, which has a vented pole-piece, while the woofer, a Dynaudio 15W-7508, features a plastic cone with a radiating diameter of 4", a large voice-coil, and the big dustcap typical of this company's driver designs. The woofer is reflex-loaded by a large port on the cabinet rear, this about 5.5" deep and 2" in diameter. The port opening to the outside world is flared to minimize wind noise at high levels.
另外，LS音箱的编号是有规定的，LS是loudspeaker即扬声器的简写，3为室外使用型号，5为室内使用系列。另外，根据这篇文章的说法，http://www.hifidiy.net/index.php?s=/Home/Article/detail/id/6222.html，更是把bbc的音箱分为一级监听和二级监听，5系列都是一级监听，3系列是妥协的二级监听。所以bm6a的配置是一级监听的配置。
