JBL LN3 Project, *Official Thread

[Lancer]

I have been talked out of the L112 crossovers by a friend of mine who has heard and built more JBL systems than anyone I know, David Dicks of commonsenseaudio.com.

It sounds like you need to add a few people to your Contacts list then. I would imagine that's why you're here. The L112 networks are used with the L96, L112, and L150A components. There is nothing at all wrong with the L112 networks, they perform exactly as intended. The L96 components work best in 1.5 to 3.0 cubic feet and the L112/L150A components work best in 1.5 to 4.0 cubic feet.

It would be very helpful to decide on drivers first.

[Nightbrace]

Ok, for now I think I am going with the 2214 H woofers, LE5-6 mids, and the LE25-2 tweeters. These are all readily available for me, and I would like to get these done and at least have something to listen to in my other room./ I am thinking the L100 crossovers would be the best place to start with these speakers and modify the low end capacitor as needed to compensate for the larger cabinet size. The L-36 crossovers are definitely the worst choice with the different woofers.

I'd like to also get a complete L-112 system, but why would I want to strip everything out of them and just put them in these cabinets?? I might as well just keep them original right?? That being said, if I want to get an original pair of JBL speakers, how do the L100T's compare to the L112's?

[Nightbrace]

I know you guys may think my choices for mids and tweeters may be a bit tame, but the L36's in the room that the LN3's will be going in sound fantastic, all they need is more bass to sound any better.

[Nightbrace]

What do you guys think of my selections?? OR should I reconsider??

Hello can a 2130 be used to make a 2203

Nightbrace has not been a member for YEARS -
His post here was from 2005 ...
he will not be replying to your Q ...

[grumpy]

Without just trying it ($75 aftermarket kit? and presumably with the tools and
experience to construct and evaluate), you would need at least information
such as is present for other drivers in the technical area (but is not for these drivers).

At one point, GordonW seemed interested in these things.

[bldozier]

Pl2230 seems spot, for using the motor swap.

Model 38cm cone type Woofer Impedance 8Ω Allowable input (continuous program) 100W Sound pressure level (new JIS) 93dB Frequency characteristic 30Hz ~ 1kHz fo 16Hz Crossover frequency 800Hz Voice coil diameter 10.2cm Magnetic circuit weight 5.9kg Magnetic flux density 12,000gauss Enclosure volume 113 ~ 170liters Depth 146mm weight 7.5kg 2203 Model 30cm cone type Woofer Impedance 8Ω Allowable input (continuous program) 100W Sound pressure level (new JIS) 91dB Frequency band 30Hz ~ 1kHz fo 16Hz Crossover frequency 800Hz Voice coil diameter Material 10.2cm · copper Magnetic circuit weight 5.4kg Magnetic flux density 12,000Gauss Enclosure volume 42.5L more depth 12.7cm weight 6.8kg

Gordon from renton is hard to get a hold of

[grumpy]

IF flux density and coil diameter were the only parameters to compare, sure.
If you've also compared gap clearance, depth, clearance to back plate,
and pole-piece/top-plate height, you're getting closer.

[speakerdave]

If you have functioning original 2130's in good condition they really should not be destroyed. They are part of the D131 and subsequent extended range and musical instrument family of 12" Alnico drivers which are valued for electric guitar amps, etc. JBL no longer makes kits for them.

As other responders have said, for hi fi bass drivers the SFG ferrite frames will be better anyway.

Both are listed here as
3/4 and 9/32
According to the charts information
Early alinco is the same measurement
As ferrite, verbatim.
