We had maintenance the excellent vintage machine of of former years, If we had maintenance good, a machine may also respond to it and it will sound by good touch, Such as JBL4343 and TANNOY/ARDEN, sound by quite good touch. If you the customers think that there is not so good sound recently, Please speak to us, We will do suitable advice. I will introduce you the two types of sets of speakers, That is born again by maintenance this time. Akihabara shop Tomohiro Kawai |

First of all, JBL4343. This is the studio monitor speaker which won popularity in the 70s. The model of a photograph is 4343BWX, The type of a ferrite magnet. Box color is wood. Units 15inch bass/2231H. MID bass/2121H driver/2420 Tweeter/2405, 4WAY composition |
|
First of all, 2121H MID. Maintenance is - edge exchange and voice coil cleaning, Gap (carrying out center appearance) adjustment. |
|
|
|
Next 2231H of bass, - edge exchange and voice coil cleaning, Gap (carrying out center appearance) adjustment (Same as 2121H) |
|
A continuation, TANNOY/ARDEN. This is the model to which also won popularity in the 70s. This is the early type, A unit is HPD385 Aruniko. |
|
|
|
First it is HPD385 of a coaxial unit. The contents of a maintenance is ・ Edge exchange. ・ internal cleaning ( almost of them made rust) . |
|
Next attenuator, The photograph right is ENERGY and left is ROLL-OFF. Attenuator becomes immediately bad. GARI has generated the great portion of ARDEN When we bought. We also made internal cleanings. |
|
By the above work, ARDEN becomes good so that it may improve. In the Akihabara shop, although we sounded with time-tested LUX SQ38FD, The classic, the vocal thing, etc. are sounding the good sound fascinatingly. If you have interested in this sound and speaker, Could you go out to the Hi-Fi-Do Akihabara shop? |
