2003年6月13日 · By the time one compares specs in the 1979 component catalog to a 2220H cut sheet ( found at 2220H ) one sees that JBL has morphed the old 130a into the 2220H/130H type speaker .

A 130A/2220 cone kit in a D130 frame will not make a 130A. As the OP noted, one reason that the early systems sometimes have D130 as woofers is that JBL (as did EV) used to market the "building block" idea of starting with an extended range driver and then adding a crossover and a tweeter or horn when the budget allowed.

2015年12月31日 · From the engineering chart, JBL recommends approx. 40 square inch port with a 2" duct (tunnel). Of further interest, the PR15 drone cone is designed for enclosures from 5 - 8 cubic feet.

The 130A used exactly the same cone as the D130. I think JBL decided my "goop" treatment of the "F" series was a good idea for all these cones. It reduced surrounds cracking from drying out.

The D130 was the second low frequency loudspeaker introduced by James B. Lansing Sound after the D101 of 1946. It was personally designed and developed by James Lansing. It incorporated a 4" flat wire voice coil attached to a light, curvilinear cone with a 4" aluminum diaphragm instead of a standard dust cap to extend high frequency response. The coil was immersed in one of the strongest ...

Hello, To hose wit knowledge I will like to know if JBL ever made 130A grey frame that reads on decal 8 ohms with the typical paper roll edge cone of the 60's and the cone reads 21057.

JBL was a small company with their main offices above a candy store, and the manufacturing scattered in a number of buildings up and down the street, near Glendale, on Fletcher Drive. They made the following speakers; the D130 a full range 15", the D131 a full range 12", the 130A a 15" woofer, the 130B (same as the 130A, but 16 ohms),

Except--making a 130a out of a D130 to reproduce recorded music--that would be a problem because fidelity would be compromised, but going the other way, i.e. coning a 130a frame with a D130 kit to play your guitar through, if you like the way it sounds, I don't see where there's a problem. But don't wreck a good 130a to do it.

2016年3月4日 · Hey guys - I have been listening to my JBL C-38s for the past few weeks, and have been LOVING them. They have the 001 load (130a, 175, n1200). They have a midrange that is simply gorgeous and easy to listen to.The midrange and aesthetics actually ousted the 4430s from my living room. I am looking at doing some additions to dial things in for a wider range of music types. My thoughts are:
