Default Hi End JBL BI Radial 2344 for Sale

In the quest for more space around here and the pace of change in my system I have decided to sell the much favoured JBL 2344 Bi Radial Flare.

The JBL 2344 provides outstanding clarity and imaging without any colouration normally associated with horns.

I have used this design for about 2 years and when set up correctly it performs flawlessly. Those familiar with this design will realise they are now obsolete items and rare as hens teeth in good condition.

My pair are in very good condition. The asking price is AUS$295.00 for the pair plus shipping (anywhere in the world).

I will provide complete details of specifications for interested buyers and crossover schematic and setup assistance for the buyer.

They will be slated for E bay in 7 days.

regards

macka

Here is a pic of the product in use, it goes beautifully with the Aleph or X Aleph by the way.

Bill,

You shouldn't have any trouble obtaining 2344's in the US. They show up on ebay all the time, and there's always Jammin Jersey

If you don't want the 'name' P.Audio make excellent clones for good money. My original 2380 and clones are hard to tell apart. I don't know who the US agent is, but I'd pay about $US60 ea for new P.Audio's here.

The P Audio are similar but not entirely the same products due to patents on the JBL Bi radial design (JBL aren't quite that stupid).

The polynomial design equations for the horn contours are JBL interlectual property and determine the resulting smooth response and coverage angle.

It is unlikey that the P Audio product would deliver the exact same performance paramters for these reasons.

But if cost is a major issue and you are prepared to fart and play in the ointment with the unknown then so be it.

P Audio make an interesting range of what could be termed aftermarket models, some of which are a ripp off on JBL models names like the famous 2241/40 bass driver.

I'll leave you with that thought given the general ethics and moral attitude towards patents and original designs around here.

Jammin Jersy have some 2344s from time to time for US $300 or so a pair but you buy as is with no Kit and no support on how to make the crossover do that ruler flat curve...if life was only that easy, Humbug

Unless I'm reading the info on US patents wrong, the one applicable to this flare has expired.

Assuming that I'm correct, then I could have a mould made for these flares indistinguishable from the original in a couple of days, if I so chose. So why couldn't they have the same performance? Are you basing your comment on actual experience, or mere presumption?

Looking at the P.Audio site for their specs on the 2241 vs the TS paramater list I downloaded from the JBL Pro site, they're different enough to be considered different drivers. Ditto the 2242.

LOL.

Please explain how this is at all relevant.

Your flares are sold, so there is no backup from you to Bill F to "make the crossover do that ruler flat curve" if he sources his flares elsewhere. I merely pointed out two possible alternatives, well 3 including ebay, after your flares were sold. Jammin Jersey are a reputable store and I bet they would have thrown in some bolts if asked. Otherwise they're not hard to get, nor expensive and all the pro's I know would have a box full of them on hand (remember who JJ's customer base is) anyway. Strawman.

I know it's winter in Melbourne, but be careful you don't get sunburned basking in the glow of your self righteous indignation.

One of the reasons that patents are granted is to bribe companies into publishing their secrets in exchange for a short term monopoly. Then the state of the art is advanced as others incorporate these ideas. Patents can't be renewed indefinatly

Variac, I agree. The 2344 flare in question isn't even made by JBL any more, so they've obviously found a better way (technically or economically) of doing it, to their mind at least.

I'm only going on practical experience with the device at hand and about 2-3 years trying to develop a crossover that would work with the right eq curve.

JBL in the end relented and sent me the schematic. This schematic is now on their web page hidden aware in a dark corner but not everyone is aware of that.

The buyer got the kit which included all this information and vital parts for the crossover, I figure thats worth 2 years hard work.
