상태는 무척 깨끗합니다만...
좀 문제점이 있습니다만, 잘 수리하면 괜찮을 것 같아서 구입했습니다.
인터넷에서의 글입니다.
755E의 출시는 1969년경 755C에서 대체되면서 부터입니다.
Frequency Response: 40-15,000, Impedance: 8 ohms, Sensitivity: 92dB/1W/1.2M
These later versions should not be overlooked because they sound good. Supply is drying up but nice clean units with intact cones show up ocassionally at eBay - 755Cs normally trading from $700-$900/pr. and the 755Es for $500/pr. I have not come across a modern 8" full range driver that sonically comes close, so they are still worth it in my opinion. Amongst the classics, the only 8" FR drivers I've heard that compare favorably are the rare and hard to find Japanese Pioneer PIM8L OEM for the Lafayette SK98.
The most important consideration when purchasing any of these drivers is to make sure that the drivers are matched! Since they were used in various applications, they may have been electrically damaged or physically abused. Typical problems include partially damaged voice coils. This usually shows up when tested with a DVM, for example the DC resistance reading on my Altec 755A is 2.2 and 2.3 ohms and 6.8 ohms for both 755Cs and 755Es.
At a reasonable price, slight cracks or splits in the cone material can easily be repaired with careful application of Elmers glue and will not significantly impair the sound, if the voice coil is intact. Unfortunately I am not aware of NOS replacement cones for the 755A. There may still be replacement cones available for the "C" and "E" but the availability of original voice coils for these models is also unconfirmed, I have a pair of 755Cs with damaged cones waiting for this procedure.
Here are some 755 sonic impressions from esteemed hobbyists collected from Sound Practices list archive:
Joe Roberts: "Well the 'C' is pretty good. A little bit less high frequency energy than the 755A but good nontheless. More tilted towards the lower mids and a little less crisp than the 'A'.
jc morrison: "by the way, i would also like to add that the later 755s are, in my not always respected opinion, much better than the early ones, which are too peaky for my taste [especially joe's favorite, the really dry cones...] i have heard a lot of 755s. i like the c's and e's crossed over to a tweeter (yegads) in a tapered pipe. these are some of the nicest direct radiating midrange speakers of all times. make a nice pipe drea with a 755C or E, add a focal titanium tweeter: nice, in my book anyway...."
Koji's [of EIFL] translation of Stereo Sound "Tube Kingdom" No. 3 comparison:
Altec 755A - "...reproduces musical sources as it is. The presence of musical instruments is excellent..."
755C - ".....sounds modest but sonic qualities very amplifier dependent. Very good for monitoring the sonic characteristics of amplifiers."
755E - "....also sounds modest, calm, thick and beautiful. Very good for a real audiophile."
WE 755A - "....you feel as if you were embraced with music. Sounds open and brilliant."
