JBL L200B with 2216nd, LE85/H91, and 077. Crossover recommendations.

[1audiohack]

I am interested in this thread as well.

I have a pair of 4333’s that have had all three horns in them and I am just not happy with them. I have done a fair amount of DSP work with them and of course just for fun ran the stock crossovers too.

I need to get them out and really work on them as it’s kind of been a just for fun here a little there a little project.

The 2311’s in the 4350’s seem less objectionable and I think it is the crossover points allowed with a 12” between the 15’s and 2441/2311/2308. I am either going to swap the 2235’s for 2234’s or most likely 2216’s.

I haven’t had a single day to myself single mid April. Grrrr. Maybe this weekend haha.

All the best guys.
Barry.

Hey Barry,

Regarding your comment about trying all three horns, specifically which horns are you talking about?

On a larger topic, in my experience virtually every horn sounds better when you raise the crossover frequency. This would align with your comments on the 2311. In an earlier time, JBL used that horn with a 500Hz crossover (Then it was called the HL93 with the lens). Bumping it up 1100Hz would certainly help! Similarly the 2307 horn in the 4343 is pushed up to 1250Hz which can only help.

Unfortunately in both cases we are talking 4-ways... trying to keep things simple in the L200 vein does present a challenge.

Mr Widget: I don't accept your Feedback
This is an explanation what you lot are doing wrong and you keep doing it over and over.
I'm here for that enquiry made by the OP and that enquiry only. I'm not here for your entertainment.
You've missed the point unfortunately. Earl missed the point and went all over the place and started regurgitating other peoples
designs, ideas ect. He did not ask further questions to actually determine other important relevant information.
The OP made it clear why and what he wanted. Then Rob unfortunately over reacts and it over.

Example
If you ring up a bank about something specific to your accounts and you have questions its it appropriate to listen
and understand why they are calling? Ask further questions so you can fully and correctly answer and the enquiry quickly and
efficiently. What you don't want to hear is someone blathering on about what they think and what someone else did.
You don't want to on the phone for hours or making several calls and no resolution.

This is my world. I build systems, I design customer journeys, I train people. I'm an expert in that area and made a career out of it.
Coming here is no different frankly. It never was and it never will be.

If you feel my approach is condescending your in the wrong business. You might be and that up to you.
I don't have to fit in with your mentality and how you see the world.

I don't suffer fools gladly.

I receive scores of "specific direct enquires" from all over the world and its growing all the time.
Condescending in not the feedback or in the testimonials I receive.
Your attempts to label and make defamatory comments towards me are pointless and don't answer the issue.

Hello Mr. Widget;

2307’s, 2311’s and 2312’s have been in my 4333’s as well as a pair of 2307’s that I parted off in a lathe at the 1.5” bore point and re-flanged them to accept 2451’s. I needed the 2311’s for another project.

So this is what I have: …Looking for some help me design crossover or suggest a crossover that would work well with this? ….

Any recommendations are appreciated. IÂ’m kind of new at this.

Ian it seems you may have missed the last sentence of the original post. ?

Hello Barry

I think you hit the nail on the head.

That is an open invitation from the OP for any and all suggestions. That means any member of the forum who has a suggestion is welcome to post. I will admit to a novice it can be really difficult to determine which road to go down but that is the nature of the beast on any of these internet forums.

Confirmation
To be clear you are definitely wanting to add the 077/2405 slot radiator and make it a 3 way?
What power amp or amplifier are you using?
Do you know which diaphragms you have in your LE85Â’s?

If l upset the natives and wildlife with the tests you maybe requested to make a donation. Lol

I have attached images of the drivers to relieve any anxieties Earl may have about whether any of this is real.

Thank you for your generous time and efforts with this.

I have the 077, I figured if I have them then why not? As my understanding is the LE-85 doesnÂ’t do much above 12k hz.

This will be ran on a 30 WPC Fisher 400 tube receiver with the audio source being a modern DAC.

The diaphragm in the LE-85 are new Radian 16 ohm diaphragms.

The reason I was wanting to crossover at 1,200 hz is because my understanding is the H91 is distorted below that level and from what IÂ’ve read the 2216nd is capable from 30 hz - 1,200 hz.

I have both L200 and L200B cabs, I figured I could play with which port type (1 vs 2) sounds better. Although the L200B are in much better cosmetic condition.

Don’t be offended but you what we call pig headed. Through and Through
Start using it (your brain) instead of blowing off your big ugly New Yorker mouth. There’s nothing worse. Your a really Bad Ambassador for anyone watching this forum from anywhere in the World.

They are watching you.

You reactions are very offensive and defensive person. Your frightened or something? Your passing the blame.

You don’t have the bandwidth to investigate, understand and moderate. Your not prepared or capable of accepting change.

Your ineffective and obsolete: Deleted.

Ian, don't be offended, but look in the mirror. You are not being a very good ambassador yourself.


Personalities aside, you have obviously put a fair amount of thought and effort into the technical side of your posts, but so has Earl and so have others. This is meant to be a collaborative space, it works best when people work together building on each other's thoughts and experiences. It's great that you want to help others with their designs and their DIY projects, but try to be more like Nelson Pass, he is able to offer wise council without being condescending.
