2122H vs 2202H for 200-800Hz

[pos]

Hello,

What would be your preference between a 2122H and a 2202H for the 200Hz to 800Hz region (or maybe 250-1000)?

That driver would sit between a 2245H and a 2435H mounted on a H9800 horn.

The question could also be rephrased as "Which speaker is you favorite in the low mid between the 4345 and the 4355?"

thanks

- Altec 414-8C is my first choice of midranges to try to voice with that specific combo ( I don't have any , so it's just wishfull thinking ) .

- I don't like the 2202H at all .

- I like virtually every ten inch that JBL has made . ( ie ; 2122H is my second choice ).

I have never looked at these Altec drivers. Will do, thanks!

I don't like the 2202H at all .

Why is that? I have read somewhere that it could be considered "slow" compared to the lighter 10". Is that your grief?

Perhaps it's because I was exposed to this midrange ( 2202a & H ) in the Sound Reinforcement business over a long period of time ,,,that I became convinced the driver has a problem wherein the driver seems to produce overtones of it's own .

Only a complete ETF analysis of the woofer ( including a CSD "watefall" obtained from within an anechoic chamber ) would expose what I think it's problems are . Since that's not about to happen , I just steer clear of the driver .

"Slow" doesn't have much to do with it / in fact , I would likely prefer to add a coating of aquaplas to the cone to see if that would "fix" my perception .

Either a 2122 or a 2123. I use a 2123 with a PTH1010 driven by an aquaplassed 2435. Works for me.

Either a 2122 or a 2123.

I'll second those choices. Make sure you go with a CC nework, too.

I have a pair of older Altec 414-Z drivers I'll eventually get around to trying. I am really curious about them. The fellow I sold my 4355 clones to ended up using a pair of them in those cabinets.

I agree with you about the 2202. I think it is a large part of why I am not crazy about the 4350/55s.

I also agree that the 10" JBLs in general are all quite outstanding woofers for their intended applications.

I'm with Ian.

2 2234H per side in an 2234 low end configuration. The second 2234 crossed over to the H9800 around 800Hz.

Yeah!

[Ian Mackenzie]

I might even do that with my 2435 be drivers if I can find a 9800 clone since the current crop of consumer horns appear NLA (perpetually backordered)

[pos]

Unless I already had other drivers in-hand, the 2122H is what I'd start looking to
get/assemble if finesse vs. slam were the intent.

Yes, the smaller the doghouse the better, and in this regard the 2122H is a better choice! Finesse is definitely what I am looking for but... I want some fine slam!
thank you!

The 9800 horn is intended to be matched to a large diameter driver with a deep profile.
(...)
However, I would not recommend the configuration you are looking at as you will have significant time alignment and crossover blending issue with that horn and driver.

You would be better served to look at a 1200FE driver (if you can wait 12 months) or 2234 (2235without mass ring).

Yes, that is one of the reason I hesitate between the 12" and the 10".
I remember reading Bo's comments about the 4345+H9800 he listen to at Rich's place (this is the one H9800 clone pair I will be using, by the way!). He found it didn't blend well, and you offered the explanation of the mismatch in radiation area between the 10" and the big horn.
My initial plan was to use a rectangular PT wave guide above the 10", but then Rich offered his H9800 in the marketplace and I could not resist...
The 1200Fe, as in GT's DIY, is in fact hard to get and costly (specially in france: we pay twice the figure US customers pay, plus this figure in in €...).
I was even thinking about trying the 128H from my 4412 in a closed box. I think the 1200Fe is an evolution of the 128H the LE120H is, and the 1200Fe looks similar), with an only slightly higher sensibility, so maybe it could work...? I really like the midbass of my 4412.
What other 12" could do the trick? Some TAD?

The time alignment and sensitivity issues will be dealt with a digital active crossover.

The 2234 (as used in the venerable 4435) is a very impressive driver and would work well at both ends. See if you can find a 2235 frame and have it reconed asa 2234 or remove the mass ring of the 2235 carefully. If you add a second 2234 and load it like the 4435 you could dump the 2245 and biamp the horn.

Yeah!

But I really like the sound I hear from my 2123 (if only it could go lower).
2234 are also hard to come by here. I have only managed to obtain one 2205 basket that I could recone. I would need 3 more. And the price for reconing these is almost as high as reconing a 2245H.
Well, that is something I will keep in mind! Thank you.

Widget, Don't you have a DIY setup with a Sub1500 + 8" (2108H?) + tad horn? What do you think about the blending issue betwwen a 10" and a H9800? This blending issue is sometinh I will already be able to look at with my 2123, as soon as I can test the H9800.

I will be looking for these old Altec woofers !

Here is a blog entry of a japanese guy that tried a 414 and 2213nd in place of the 2202 in his 4350 :

Recone your 2202H's to 2204H's. :dont-know

Way back in the old days when Project May first started up alot of people wanted to add a ten between the fifteen and the H9800. Greg was adamantly opposed to such a proposition. - "Won't work."

I think it is interesting that JBL uses dual eights with the Array horn in the SAM2LF though.

I know that the 1500AL and 1200FE both work really well. I could try my 2122H's or 2123H's at some point I suppose...
