Just saw this on the new JBL 2269H dual 4" V.C. differential-drive 18" pro sub with 3.5" peak-to-peak excursion:

sweet!!!!!

Looks perfect for adding just that little extra bottom to a persons HT setup:D

Too deep. I'd hafta make some spacers to fit 'em in my monster sub.... :p

This should be some kinda monster. Seismic, in a Cosmic kinda way :D . Can't wait to see what Zilch will do with it! ;)

Can't wait to see what Zilch will do with it!With what? A 2269? We couldn't care less what Zilch would do with one? :rotfl:
The thing to watch is what JBL is doing with this purpose-built transducer. Very nice!

I didn't pay much attention to his Q&D 4430 thread until yesterday, I find his little lab interesting and I like his willingness to explore possibilities. As for what JBL does with a transducer, that's a no-brainer, of course. I hope that the 2269's advanced design makes it into the home market in some form. I respect that you are steadfast in your commitment to recommend that JBL transducers be used for their engineered ,purpose-built intent. However futile and bizarre it might seem to some, I think it is interesting when members explore and think outside the box. Kind of a "Let's see what else can be done with it"--constuctively. Not to say that a reckless promotion of such a thing is good for us either, I don't see that Zilch is guilty of that, I find him to be fairly thorough in his projects. I'm beginning to understand you a bit better Giskard, it must be frustrating to deal with less informed people, to put it politely, just continue to keep the record straight in your own unique style and we'll all appreciate having the comfort of an authority on the actual bottom line from an engineering POV.

This should be some kinda monster. Seismic, in a Cosmic kinda way :D .It's running with E155's presently, but I acquired a pair of 2241's for it. Then I figured out how to make 2242's fit, so I was thinkin' about doin' that.

Now I don't know WHAT to do.

It's all enormously silly, of course. Can't put more than a couple of watts in even as they are before everything in the house rattles.... :p

I hope that the 2269's advanced design makes it into the home market in some form.'Not sure if the trade-off would be worth it. Who really needs 140db in their living room, especially if that might be pushing the linearity? Of course, that might also mean that when limited to the kind of output normally required in a relatively low-powered home environment, it could be especially linear and low distortion... :dont-know

John I don't know either. I've run into a suprising amount of people that feel the need for that type of overkill, I just like the idea of it. Back in the day, there might have been the same type of speculation regarding the B460. If you look at the literature, it seems if these were aimed at augmenting the L250, for crying out loud!.

I think I agree with you about the waste of time and money that many members go through with their seemingly random design attempts... I know about it from firsthand experience!:( But, this post seems to be an attack on the intellect of a fellow forum member... that's just not necessary or cool.

We had a nice discussion about these newest transducers. We were asked not to take any pictures. They are very nice. I'll see if it's ok to post anything else at some point. It's all gotta come out sooner or later anyway.

Okay, get out the flame throwers. :biting:

Has anyone got TS parms for this 2269H woofer yet?

Hmmm, I wonder how it would behave in a sealed box. :p

At first glance I thought the Vertec cabinets were very pricey, but I think it's time to give them a second look. Maybe I wouldn't need two of these new VT4880A in my studio, maybe one would be enough. Seriously, I'll be pricing these babies tomorrow. What do you think, one Crown CE4000 in bridge-mode per driver?

When I bought my B460s some people said they were overkill, but they were wrong.

I realise its OT because I am not talking product but a sub that actually is doing the job does not actually have to play super loud. Besides, very loud bass can be quite damaging to your ears. After the novelty of the sound effect wears off it becomes quite tiring

I would rather have another 5 hertz of extreme extension (say 25 hertz) with low distortion and moderate sensitivity than a system that peaked out max dbs at 40 hertz.

But I guess if the people you live with are deaf and you live in a rough neigbourhood where hoons drive by with 1000 watts in the trunk its okay to stack 2242's to tbe ceiling!

Please, no Bose wave cannon jokes.

Please, no Bose wave cannon jokes.I'll refrain from the inside jokes as well. Besides, they aren't really inside jokes per se. These transducers were designed to kick unholy ass and they do that extremely well. For personal use in my home they have absolutely no function whatsoever.

One of my favorite things about JBL is that their speakers often have both finesse and kick-ass level. But if this is not the case with the VT4880A, I may have to keep the B460 subs and add switches on the wall to suit my particular listening mood.

http://izzyweird.com/temp/knife_sw.jpg

And when I'm really in need of a sub-bass fix, I can turn them both on. :p

I may be buying one or more of these so I would really like to know the basis of your opinion. Is your opinion of the VT4880A based upon actually listening or better yet, AB comparison? Is it based upon a consensus of other astute listeners?

In clubs like Studio West in San Francisco I used eight Cetec Gauss 18" subs because at the time (1979) JBL did not have an 18" woofer robust enough for that kind of service. The rest of the 4-way amplified system was all JBL (4 each 4560, 2395, 8 each 2405. etc.). Similar to your above statement, I would probably not use Cetec Gauss woofers in my home. They kicked-butt, and they sounded pretty good, but they definitely weren't JBL.

It would seem to me that the advantage of a speaker that could play that loud would be that with an equalizer you could could play rather loud (not 140 db) at lower frequencies because the 10 db down point and such are still very loud all you need is plenty of power and the right equalizer and in Zilch's case a little work on the house apparently. (probably a lot of peoples case) I've yet to hear anybody talk about a price. I think the list as a spare part is about $2300 but I'm not sure who you buy it from for that or if you can get it for less. I know when looking at 4880 and 4881 the suffix is very important.

I built a giant set of transmission lines that were clean and low and fairly loud but I'm pretty much done with them because they simply don't have the dynamics and output that a horn does.
I used to house a set of 2242's in these 6 foot high cabs:
http://www.steevee.com/images/studio/tympanis.jpg
But now the 2242's are much happier in these:
...couple of different pics of bassmaxx sub boxes that I modified:

http://www.steevee.com/subwoofer/subs16.jpg

Eventually I'm going to flop them on their sides underneath a new system.
I was interested in the JBL box...what is it the ASH6118 ?, not sure....but these are pretty much the same size. I really , really tried to go the T-line way but I don't like em "as much" except for the fact the footprint can be smaller...not that the big ones I built had any kind of WAF. ;)
