JBL 4301B

[Nightbrace]

How favorably will the L19's compare? What other monitors under $200 will compare will either of these that are less than 19" tall and 12" wide?

I believe you have to have L19A's to match the ferrite drivers in the 4301B. The plain L19 uses alnico drivers.

is there much of a difference in the crossover?

JBL should have the 4301 info at their pro site.

JBL should have the 4301 (crossover) info at their pro site.3103, here: http://www.jblproservice.com/navigation/Network%20Schematics.html

It appears both the L19 and L19A both use the LE-26 for HF, the same as the 4301B, while the plain 4301 uses the LE-25 for HF. And again - the difference in LF between older and newer versions is alnico and ferrite.

And again - the difference in LF between older and newer versions is alnico and ferrite.And, in the ferrite series there are engineering differences, too, as reflected in the Thiele-Small parameters.

Bo,

If those are the ones in your shop they are a step up on the L100 in many ways..all that out of a small cabinet makes them sweet.

I heard the ones in Bo's shop and they are very impressive for the size and mint I might add.

Got to admire oll Tin Ear Ken..he knows his stuff.

I think it would go nicely in an apartment, great bottom end.

I've been waiting for something..where is it?

And don't be smart.

In looking at this thread, the 116A (L19 woofer) and 116H (4301B woofer, inverted dome) have identical parameters, which is quite a fluke, as the drivers look much different from each other. They share the exact same tweeter. The crossover is nearly identical with the 4301B a 16.5uF and L19 a 18uF cap on the woofer. Cabinets look very similar in volume (within 5% volume-wise), but of different dimensions. Why isn't the 116H woofer, then, listed as a replacement for the 116A in the L19's crossover schematic sheet? Is it due solely for cosmetics? I have an L19 w/o woofers and was thinking about dropping in a pair of 116H from my beat pair of 4301B. I should expect identical sound, right?

[boethius]

Well, inspecting both crossovers, there is a 10uF (electrolytic) on the L19 crossover, as well as two coils and a film cap of unknown capacitance. A sand resistor, too. The 4301B has two film caps, no electros. Strange about the 10uF, the L19 network referenced on this site does not include a 10uF cap in the network.

No biggie, the designer often starts from scratch with every model... I went over these differences when this forum first started ten years ago.

The 116A and 116H were acoustically equivalent and both used the C8R116A recone kit.

I personally consider the 4301B a JBL hallmark. Greater by far than the sum of its parts.
