A questions I cant seem to find, will they ever manufacture a BE fram for Altec 288s?

All the JBL talk about them is making me drool! :) :eek:

Don't think so.You can always ask GPA if they will not be making them then answer is NO :(

The answer I was afraid of :crying:..... I doubt GPA will make them. I am not sure the manufacture cost of these, but as we know they are expensive for the JBL's, which probably means a high production cost (since walmart isn't buying and selling them ;)


I am sure there are many people like myself that are dying to put a BE fram in their 288!!!

I don't know but my all aluminium frams in my 288's sound darn good to me.And I am quite pleased with them.

To me, the 288 seems like the ideal driver for a Be diaphragm. If GPA offered them as a factory option on their current line of 1 and 1.4 inch exit drivers they'd be one up on almost anyone else in the aftermarket supply, especially in the Alnico version. I'm not sure of what the tooling cost would be to get setup to build them, but if true extent thought there was a market for 244x version, then I'd think there would be a market for Altec versions as well. If they did a 1.75" JBL (242x) version a slight tooling change could produce a 1.75" Altec version.

BTW, I'm pleased to see GPA one eBay now, and the prices for factory fresh NEW drivers is pretty reasonable - often cheaper than some of the 50 year old drivers getting flogged out there!

Production shipments of 4 voice coil diameter diaphragm assemblies will begin in the second half of 2009, with 2 diameter, 1 diameter and 3 diameter shipments ramping up thereafter. These diaphragm assemblies are engineered to fit the majority of existing compression driver motors.



If you don't see the driver you are looking for, please contact us for more information by signing up at the Truextent website (http://www.truextent.com/).

I'd just give them a shout and see if Altec drivers are on their list of drivers to be.

And Orange County is having another 15% off sale for the next 3 days, that's about $90 ea off the price on the 4" phragms for JBL drivers.

I am too ! Their 288H alnico versions have received very good reviews, people that have bought them have been very pleased with the sound quality.Steve Mac over at Altec User Board built a DIY system with the GPA 288H on 511E horns and he built dual LF horns with JBL 2235H's in a HT app. and he said he couldn't be more happy with it. ;)

I thought it funny to see this thread today because I talked to Bill H. at Great Plains yesterday and we were discussing the Be for Altec drivers.

I told Bill I had JBL 2446 w/Be diaphrams installed on them and I can't live without them! I asked him if Tru-extent was making them for Altec drivers and he commented that he might help them design the diaphrams, but nothing was for sure on the deal.

I then told him there were plenty of Altec followers that would definitely want the Be diaphrams.

So there might be hope for you Altec fans.

Not to be tacky, but aren't the BE diaphragms pretty expensive, compared to other materials?

I'm not debating value, just making a comment.
I don't know about the as yet unavailable Altec diaphragms,
but I believe the JBLs are like $600+ expensive, right?

With ratio and proportion, you can figure it from clues left earlier :D

(But yeah, they are kinda pricey)

agreed, my wife about had a fit when she saw the reciept...

she no longer was concerned about the cost of some vacations she had
been contemplating...

;)

on the plus side, my understanding is that they may well
be the last pair of phragms i ever need to buy for this pair
of compression drivers... as they will be used in home only...

There is a thread now at the Altec board that says they will be available very soon. The 1.75" will be released first followed by 3" ?? Don't know for sure. Tru-extent says on their website that the 4" production ramping up for the second half of 2009 and then production of 2.75" 1.75" and then 3" thereafter.Since we are rapidly approaching 2011 who knows when if ever they will be available. ;)


Addendum: Earl post clarified :)

They are worth every penny Heather .... have you heard them ? you could spend 10 k on other components and not have the same kind of improvement .... I think you may find others to back up this statement . !

You have 2445's already .... Be measures really ,really good in them .... you get 90 % of the TAD 4003 sound quality for 20%of the price .... They sound more like your maggies in the regions :D

That they are basically the only aftermarket diaphragm that's ever been widely accepted by this board says quite a lot.

And it's only $1200/pr if you don't take advantage of the 15% off deal :applaud:They're barely over one thousand dollars a pair on sale! :D

Here's my Hostboard post in it's entirety ;

- Actually, to the best of my knowledge , only the 4" variety has been released for sale at this date .

- The rumour is that the 1 diameter model is next in cue for production .

<> cheers

- The rumour about the release of the 1 diameter model is just that //at this time it's rumour only .

- My post at Hostboard was in response to the original poster who implied that all sizes were available . They're not !!!

<> cheers

Sounds very nice - but right now Emma is sitting at home while the furnace guys install our new Furnace and AC system - That $6500 will net us a fine rebate come tax time in the spring ... and that will go towards our "trip to Edinburgh" savings fund, unfortunately, and NOT a pair of BE diaphragms ... I'll just have to suffer with (working) stock phragms for now ...;)

Truextent Availability

- Currently available are the 4" diaphragms ONLY.
- Next will be the 1.75" diaphragms. The release date isn't clear yet. Hopefully next year.
- 3" diaphragms will probably only available for speaker manufacturers. But this is very unclear at present

Hell yeah!

But the best I have ever heard personally!

I have Be in JBL 2446J drivers on Edgar round wooden tractix horns, and they sound like they are worth every cent! And I'm on a very low fixed income!!!

Which filter did you use for your furnace? I'm going to be installing a furnace in my new home, but don't know if i should use the furnace the company is providing or purchase my own furnace filter and ask them to install it, usually what ever the companies install are standard, not much quality.

Be's for the 2425/2426 sure would get my attention if and when they become available.

I'm not going to hold my breath for a version that would work in the EV DH1A though ;)

I just purchased 3 furnace filters from home depot today, the price was pretty reasonalbe, so far I think it's going to work great. I also bought a couple more, to make cabin air filters from a normal home home furnace filter, it works great.

Brush Wellman will be coming out with the Be diaphragms sometimes next year. They should make quite a difference.:D

The 1 3/4 be phrams should make a pair of Le85,s into a super tweeter..
