Hey Zilch

You know those L200T3 networks you sent. They work! The red is the 2418/ 2342 combo no network. The Red is with the network. Your going to love this thing. I am going to use drivers and such where I know what to expect to get the hang of things. That way I can trouble shoot until I get the "correct" response to learn how to set things up.

I couldn't find a reference to where the files go in Version 7. I also looked through the 6.5 manual and couldn't find it either.

I would have thought they would have gone in the calibration directory but no -> C:\Program Files\Audiomatica\CLIOWin 7

Heh. And that's the most rudimentary version, too!

Just call that design "done" and on to the next one.

Acutally, 2416H-1 sounds a bit better, if you have any of those.

Thanks again to Giskard for turning us on to that surprisingly good minimalist network.

Audiomatica received my ISA card.

$616.73 PayPal'd today for the updated gear w/latest software, including shipping from Italy via DHL Courier.

$1020.39 total to date.

U.S. Customs duty pending.

Thinking I'll also get a "Lite" mic to mount inside my test box for woofer testing per Small....

[Zilch]

Signal conditioner, new V4.0 PCI card, CLIOwin 7 software, beaucoup more cables.

"Lite Mic02" ordered for in-box woofer testing.

Gonna hard wire through the wall from office to "Lab," I'm thinkin'....

Trivia question from Audivex: Who was Clio, and what was the TV program?

[Robh3606]

So what's up. Zilch you have that bugger up and running yet???

[Ian Mackenzie]

Yeah..like hello Man..I am twiddling my thumbs and whistling Dixie.

I reackon your figuring out how to repost 800 posts and what Clio reports

[JuniorJBL]

Check your PM's for a PC!!

Well , how's the Clio Club doing ?

- By now, I was hoping that we would have seen a few exposés of never before measured, JBL HiFi components.

- Or have you guys discovered so many blemishes in what you personally accept as "nice-sounding" ,that submitting to the tyranny of the "flat-line visual" is just a no-go at this time ? I'm aware that the inherent HF/UHF phase-cancellations from a design like the 4344 or 4345 is not considered to be a drawback as long as ones capacitors and electronics are up to the task .

- ( See Widgets' "Frequency Response thread for an interesting overview of the limitations of "measured" specs.

- A few ideas ;

(a) Tweeters; How about FR/Impedance plots for the 035ti , 044ti , 046ti & the 050ti ? As well as harmonic distortion comparisons for these same tweets . ( The gold laminated titanium 050ti might just win this competition ). It would be nice to see these specs / even though these are mostly ( or rumoured soon to be ) NLA/Obsolete "Legacy Components" .

(b) Harmonic distortion comparisons between the 108H and 2118H . It would be nice to quantify the reduction in overall "objectionable" distortions ( read; odd numbered types ) that applications of aquaplas provides. I love what JBL does with aquaplas / I wouldn't mind seeing it quantified .

(c) Harmonic distortion comparisons between a 2445H and a 2450-SL ( or a stock D8R2425 versus the aquaplased 275 diaphragm in a 2426H driver .

(d) Response & distortion specs for the legendary 112H/2108H series of 8" midbasses .

Heya, Earl!

Well, I'm up to doin' (c); JuniorJBL has put together a computer for me to run it.

There WILL be a learning curve, tho....

Excellent !

I'll look forward to seeing that, ( once all those (I's) are dotted & those pesky (T's) are crossed . )

Hello Earl

We can give some of that a whirl. The distortion won't be that easy though. Need a real quiet room cause if your looking around a 90Db reference level lots of what you looking for is 40-50Db down. So you have to make sure the furnace/refrigerator/washing machine and dryer are off and your levels are high enough above the noise floor to give you the dymanic range. Hear is a curves trying this out. This is a 2418 on a 2342 ran through the L200T3 crossovers Zilch sent me to try out. The Red is 2nd and Green is Third Harmonic

[JuniorJBL]

The PC was easy stuff. Now I just need to come up with CLIO or the likes so I can do this myself!

- Thanks for the reply Rob.

- Two and a half decades ago ( @ 1981), when Urei was redeveloping the horn section for their 813 duplex, they were presented with a similar dilemma.
ie; How to make meaningful measurements without access to an anechoic chamber ?
-Their solution was to use 4" Sonex panels to create a portable sound chamber that they said offered close to 100 % attenuation above 1000 hz.
- The test speaker sat on a stand with 6 panels hung all around it ( the bottom panel had a hole cut into it to allow the speaker-stand acces.
- The cubical interior was large enough to accomodate a duplex in a smallish enclosure. There was enough interior space to distance the test mic. 1 meter away from the duplex.

- 4" deep Sonex is quite expensive, so is 4" Auralex ( though it's a cheaper alternative to Sonex ).
- I own a lot of 2" deep Auralex panels that I use for room treatment purposes ( my own interpretation of LEDE ) .
- Personally, I'd build with the 2" or 3" stuff , if I wanted to build an ad hoc test chamber ( specifically for HF transducers ). Even when having the ability to "time-window" the test samples, I feel there is a benefit to the enhanced isolation .
