I know you've posted variants of this question elsewhere, but I haven't followed the results. That said, yes the 2206 will perform well as a mid bass driver in a compact enclosure.Quote:

I use the 2206 in between a 2235 and a 2352 horn, tried 2202's brand new and old, and the 2020, although those units have their own strenghts, nothing blends in as well as the 2206 in my application. I filter 24dB Bessel (active) I dont know why but somehow the 2202 has something anoying, most Obvious when I watch TV on the vocals, the 2206 just isn´t there, there´s only sound :)
I cross at 250hz and 1K , at 800Hz it´s just not falling into place as it does at 1K , probably better directivity match at that frequency, but ofc thats will be totaly depending on horn used. As far as the low crossover, its extremely well behaved at 100Hz crossover to the 2235 but I like the little more fat sound I get when crossed at 250, although tv vocals sound cleaner at 100hz crossover.

Here's a good starter thread for those wondering about maybe matching-up their new big Heils to a 2206 mid-bass.
:)
PS; I too have always found something annoying about the sound of the 2202 ( fwiw ).Quote:

Haha the 2202’s were the first thing to go from my 4350’s.
They won’t have any value by the time we are done here.

Jbl 2020
The 2020H has been designed with a combination of flat power response with rising on-axis response, and an optimization of the critical interplay between efficiency, sensitivity, power handling and low dynamic power compression.

It’s not a diy friendly driver.
Okay,
Just some housekeeping for wayward readers looking for info on the 2206H, here's a nice thread on the use of the 2206H for HiFi reasons.

Here's a portion of JBL's EDS info for the 2206 ( taken from the transducer Library > then rotated & straightened ).

I'm wondering if anyone can confirm ( with measurements of their own 2206's ) if the response is truly this linear between 1-2K.
A near-field measurement ( an inch or two away from the cone > with the woofer mounted in a box ) would suffice.
Thanks :)
Hmmm. I'm using JBL 12" for mids in my PA. They were 2206s and now they are being replaced by 2262 for light weight.
I wonder how the curve is for the 2262?
I have JBL 2258s on subs, and now 2453s on horns.
I scored a couple of JBL AM7212/64 boxes too and upgraded the horn drivers inside. I'll use the stock drivers in monitors.
This newer light weight stuff amazes me. I know, it's not the heritage stuff. They are now getting pretty old so to me, they are.

The curve of the 2206 is flatter but that might just be due to the use of 2 different smoothing filters ( applied to the raw data ).
Worth noting is that the 2262h curve was made in an 8 cu' ( sealed ) box while the 2206h curve was captured in a 10 cu' box.
- That helps explain the slight difference in LF response ( below 200hz ) seen.
Here's an FR comparison for you ( taken from JBL's own published graphs ).
- As mentioned, the differences are most likely in the type of ( un-specified ) smoothing applied to the data.
The 2262h "should" be the better driver ( as it's JBL's policy to engineer real improvements to their generation-lasting products ).

I like listening to the 2206s as hifi drivers more than the 2262 equipped boxes but that said I've also got almost a hundred 2262 drivers across multiple speaker systems and I have never had to open any of the recone kits I bought almost twenty years ago. They are mighty reliable speakers.
