Speaker Codes And What They Mean

The picture is a section of the basket rim of a speaker. The 6 digit code indicates what manufacturer made the speaker and when it was made. It is called the 'Manufacture Date Code'.

Here is a list of some of the speaker manufacturers and their EIA codes:

Credence117
Plye1098
Rola285
Eminence67
CTS137
EV649
Oxford465
Altec/Lansing 391
Utah328
Quam270
Jensen220
Weber1279
Cleveland433

So, the speaker in the image above would have been made by Jensen (220) during the 27th week of 1951 or 1961. The year is confusing because it is only a single digit. In later years, the EIA converted to a 4 digit date code so the year could be easily identified. There are 2 acceptable methods of displaying the EIA date code, with or without a hyphen between the manufacture code and the year/week code. Some manufacturers also attached other letters to the end of the date code to indicate day of the week, work shift, serial number, lot number, etc. The EIA only specifies manufacturer and year/week code. Anything else is at the discretion of the manufacturer.

The JBL L-100 Century isJBLs most famous vintage speaker from the 1970ies and is an absolute classic.It has been produced in several versions over the years, so it is well possibleto find slightly different midrange and tweeter placements. You can find anexample of a newer design at the end of this article.
When JBL focused onoffering foremost consumer electronics (vs. professional studio equipment) inthe 70ies, it started the L100 model, which became the most sold speaker modelup to that date. No other company had produced a speaker with similar sales.Therefore JBL continued to build and sell the L- series and introduced newerversions with improved drivers and crossovers throughout the 80ies.Those newerspeakers of the L-series do not have much in common with the original L-100.Read for example our review of the JBL L112 Century II speaker.


JBL L-100 Strengths and Weaknesses

The JBL L-100 Century was a milestone and huge success for JBL, but was not free of weak spots. At first to its strengths:
  • It has been noted in professional magazines at the time that the JBL L-100 lacks distortion at a level that has been outstanding.
  • It ranked with some of the most accurate speakers out there and Stereo Review Magazine claimed that 'certainly no other has been better'. Such ultimate statement is not professional, but it gives an idea of the impression the speaker has made.
As mentioned, the L-100 has a few weak spots, some of which decreased over the years with new versions of the L-100, other models and other drivers. Commonly claimed weak spots of the L-100 are:
  • The JBL has great drivers (considering the cost), but lacked a decent crossover. Upgrading the crossover can be fairly difficult and its finetuning requires special equipment. Overall, it can be overly costly to work on the crossover, if you are not a professional.
  • They have the frequently called 'West Coast' sound, a little flat with fairly punchy bass.

JBL L-100 Century Specs

The JBL L100 measures 231/2' to 14 ½” to 13 5/8' and is therefore a rather large bookshelfspeaker. The cabinets are made out of real wood, which causes the weight of 45lbs. per speaker. This combination was a bit of a problem for me, as thespeakers were neither suitable for any of my shelves, nor were they suitable tostand on the ground due to their sze. I, and many other owners did finally buysmall stands, which I can also recommend, as it gives the speakers the elevation,hight and position they require to shine.
Each L100 has a 12” woofer,5” midrange speaker and a 1 1/2” tweeter. Noteworthy are the controls for high-and mid-frequency adjustment. The speaker sound is dynamic, remains very clearon high volume, but basses are rather “punchy”. Personally I felt mostcomfortable when listening to Rock, but have the feeling that they are not toosuitable for fine vocals. Other reviewers noted too, that they did not like tolisten to Jazz or female singers on the L100.

Refoaming the JBL-100

The JBL-100 is definetilyworth it being refoamed. Many of them have rotted foam surrounds which caneasily be replaced. A refoaming kit can usually be bought for around $30-40,replacing the old foams will take around 1 to 2 hours and is not difficult atall! It does not require any particular skill, just a calm hand and a littlepatience. We tried out several available foams and recommend to use an 12 inchSurround Kit from Parts Express. You can find a fitting refoam kit here: > Speaker Surround Kits <. Alternatively, ask in one of the big HiFi forums, you will likely find assistance quickly.
