Energy Veritas 2.3i vs JBL L100T

The tweeter foam issue may also be relevant, I believe: I know the internal foam on JBL Ti tweeters will dry out and stop damping the domes. I may someday replace the ones in my 250Tis, if I can ever decide what foam to use. (I have the basic dimensions, so it's really just a matter of cutting it out and installing it.)
 
I tried the t3 crossovers in my L80t's, and I also prefer the original t crossovers and reinstalled them and sold the t3's, so it's not completely uncommon to prefer the original crossovers.
 
Moderator's Note: Please refrain from the recent side discussion about whether or not the L100T "Sucks".

Opened back up for now.

The op may want to try and locate some 052Ti's to replace the 035Tia's.

If you get the one for the LSR, it will be Aquaplas'ed, and add a bit more ring reduction from the dome.

Or you could replace the foam. It really does provide some dampning to the dome, and for this very reason. A little less high power breakup. :yes:
 
I know roughly the foam dimensions, and I've read several threads on it, but what type would you suggest? Where to find it?

(I ask for my 044Tis, the foam of which is starting to decay.)
 
A soft low\medium density open cell poly foam is what was used for the originals.

3/4" R X 1/2" T

Get a piece of pipe (brass 3"X3/4" nipple is great) that is 3/4 ID and grind down the outside near the end in a taper towards the inside of the pipe to make a cutting edge all the way around the diameter of the pipe.
Get the foam in a 1/2" sheet, put it on a piece of wood and press the tool (pipe) into the foam! Now you will have a perfectly round piece of foam for your tweeter!:D

You can get creative for sizes and the tool you make.:thmbsp:

Are you sure you're talking about the L100t? Because they aren't cheap, they were over $1000 new in the later 80's, and they are not very easy to find. They have the exact same drivers as the JBL 4412 which nearly no one considers cheap.

While I agree with what you're saying, the L100T does not share the same woofer as the 4412. The L80T and 4410 have the same drivers but the L100T uses the 2214H woofer versus the 128H-1 in the 4412 and 4412A.

Of course the crossovers are quite different, too.

Sweet; thanks! Any ideas of where to source the foam? I guess maybe some foam weatherstripping with an adhesive back?

Your brass die is exactly what I did here, by sheer coincidence:

You'll want to use a 30 PPI or so reticulated foam, I suspect. You may find it at a pet store as a fish tank filter.

20-30 year old foam is often the cause of the Ti tweeters becoming undamped, and then being called shrill. Address the base issue before spending money somewhere else...

It's literally a buck worth of foam, but could save hundreds in unneeded fixes elsewhere. I have yet to see any foam, that had not already been replaced, that was _not_ rotting, or already turned to slime inside a Ti tweeter. I'm not saying replacing it is easy, but material-wise, it's _much_ cheaper, and often brings the tweeter back to it's intended sound.
 
I checked the foam on one of my 044Tis recently. They were from 250Ti speakers, maybe dating back to 1985 or so. The foam was still in its original (crushed by the dome) shape, more or less, but it came off black when I touched it. I suspect it's still damping the tweeters, but only slightly.

And yes, the speakers do sound a bit bright to me.

I think it took me less than five minutes to take apart the tweeter and reassemble it. But it was kind of a whore to get the back panel off the speaker.
 
Well, I have tried the JBL L100T with T3 crossovers with different speaker cables now, and now I can see that it is a real improvement over the original crossovers.

In fact, I like this combination so much, that I probably prefer it over the Energy Veritas 2.3i's. I'm gonna AB them now.

P.S.: I'm using cheaper cables now!
 
The only way you will be able to tell is to do a comparison. You must listen to the JBLs to know if they are right for you. They are very good bass reproducers, as well as producing a great sound stage and good imaging. But no one but you can tell what will sound best to your ears. How speakers sound depend on a lot of factors as you probably know. Room placement, room size, furnishings for example. The JBLs are impressive for their size and the details of the finish, such as the veneeered backs.
I can't help with the comparison having never heard the Energy Veritas series.
If you want great bass without a subwoofer, I don't think you can go wrong with L100t. If you have a small space then just get a subwoofer to carry the bass load for the Energys.
Describe the rest of your system and see what kind of comments you get then. Good luck and keep us posted.
 
The foam for JBL's was about a 60 or so PPI if I remember correctly. I would think that the open cell weather stripping would be pretty close. Remove any adhesive first, could become a problem down the road from heat and other enviromental factors.:yes:

OP

Glad you like them with cheaper wires!! I have found CAT5E in multiples works great. Zilch always like it as well!:thmbsp:

I just repaired my 035TI tweeters this week. I tried two types of foam which I cut using a 3/4" brass fitting, ground down to form a punch. First, I tried a filter foam and the tweeters still "broke up" on occasion. The foam currently installed is cut from a makeup sponge found in the cosmetics aisle at Walmart. I used a 3M adhesive transfer tape to secure it. I ordered replacement o-rings from McMaster-Carr to secure the screens as mine were dry and cracked.

I have 3 pairs of o-rings I will gladly mail to anyone for no cost. They are, however, orange in color, not the original black. PM your mailing address. One pair per member please.
 
Thanks for all the tweeter foam help! Hmmm, weatherstripping or makeup pad? Adhesive or no adhesive?

I suspect the adhesive isn't really needed, since the dome will hold it down.

Last time some adhesive was left behind the dome it was later discovered to have mold.
JBL never used an adhesive so I see no need to use any either.:no:
 
The Energys have good bass, no question. But a pair of 6.5" woofers still won't move the same air as a 12" woofer (actually if they follow the same pattern as the 2.4, then one 6.5 will mate with the convergence model and the other will be crossed over as pure woofer). The JBLs will have more presence while the Energys will be faster and perhaps a little tighter. Neither one really needs a sub, but the Energys will benefit from one more than the JBLs. Depends on your music preference and what's upstream. The JBLs will be more warm and forgiving, the Energys more analytical.
