I want you to see data D-10 of the sound road structure of the Nagaoka [tetsuotoko] type backing loading first of all. It is the one that I calculate one and output the data of backing loading horn speaker of Nagaoka [tetsuotokoshi]. First of all, it is a point that Buckie of the main speaker such as super-Swan and D-55 and 2m50 "Total length of the horn" this is only in only 1m75 centimeter to attract attention most. The influence with a short horn is called rage [gaderu] from the characteristic in ..bass.. the vicinity of [denikukunari] and f0. However, the difference of the time of the [detekuru] sound (connection) also has the advantage of improving from a horn [karaderu] low region and the unit.
Next, shape of tube soon. The horn was made in five six sound road parts when the backing loading would be designed soon in the tube in Nagaoka master's speaker till then and length of the horn separately individual was made different length. 40 five centimeters' the horn length are matched in Buckie and it is assumed, "Total length 1m75 of the horn" though it might have been done so to avoid the influence of the standing wave. The Nagaoka master was anxious to the sound from the horn with this with no [deruno], too. a terrific peculiarityCrossing is the higher over 250hz and I examined it. Even a comparatively high compass it is what put the horn loading on [ba] convex sound ..putting the horn loading and saying.. this. This will go away from common sense "The convex sound from the horn is prevented from leaking" of backing loading horn of Nagaoka [tetsuotokoshi]. When you bring the feature together

�� bass with short total length of horn
The horn sound road part comes to be going to generate the standing wave easily soon the tube and all 360 degrees in turn �� [enkuroja-].
The convex sound leaks from crossover 250hz�� horn. The location deteriorates.

Apparently, it is possible to think only of this D-10 like a different speaker that comes off from orthodox though a popular speaker is moderate official, and is performed all the designs that became [ri] reasons though the sound road structure is examined and backing loading horn of Nagaoka [tetsuotokoshi] was understood. Without being felt, and settling to a wonderful sound are this speakers in the negative aspect raised up, and a very popular speaker though understood when auditioning. This speaker thinks that it symbolizes a mysterious backing loading though the backing loading was read, "Complex system that mixed sealing up with a resonance tube and a rear opening" somewhere.
