There are three major differences between the JBL D and E series 120 12″ speakers. First is the magnet. The D has the ALNICO while the E has the larger and heavier ceramic. Second is the cone. The D series cone has a pleated paper surround ( some earlier models were smooth with no pleats ) while the E series has a Cloth surround. The third major difference is with te coil gap. The E series has a wider gap than the D and uses what is called “Field Focused Geometry” which was adapted from the K series. This focuses the magnetic field in a more uniform pattern around the voice coil. The D series power rating is 200W peak and 100W RMS with a SPL of around 100db. The E series handles 300W peak and 150W RMS with a SPL of 103db. There is also a difference in weight. The D-120 was about 14lbs. while the E-120 is 20lbs.
\nMost guitar players that I’ve talked to who are into vintage amps and sound tell me that they prefer a speaker with a paper surround…but being a keyboard player I can’t hear any difference betseen the paper or cloth.
\nNot entirely accurate here.
\nThe voice coil gaps in the D120F, K120 and E120 are all the same… .057″
\nThe E-Series has a higher flux density in the gap of 1.35T(13,500 gauss) due to the more powerful ceramic magnet that replaced the Alnico from the D\/K Series which is 1.2T(12,000 gauss) . The E-Series is about 2dB more sensitive.
\nWhile some might prefer the D120F’s treated paper surround and it’s associated cone breakup, the K\/E series “m-roll” surround yields better low frequency response and mechanical power handling as well as the ability to be a cleaner more versitile performer.
\nEvery player that I’ve reconed an original D120F with the E120 recone kit has been thrilled with the results. Basically, it’s upgraded to a K120 with E120 power handling. Some guys have been intimidated by the beastly sensitivity of the E120…and the extra weight…but some have gotten used to it and other’s love it from the start. It can replace multiple 12’s of a lesser pedigree….and do it without complaint for….well…decades of service. What’s not to love? Turn the treble down a few notches and the high end can be tamed. Power rating is 300 watts pink noise in sealed\/vented enclosure. 150 watts in open back.<\/p><\/blockquote>\n

One more point that is rarely mentioned regarding the db rating on speakers is that every 3 db increase will be TWICE AS LOUD!. Therefore the JBL E120 with it’s 103 db output will walk all over almost every other speaker made. If I remember right it has the highest db rating of any of the usual guitar speaker choices. Yes – the E120 recone kit is a win – win for a D120.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"
