JBL 2226 for bass

I know the finished speaker systems were wired so that the system had conventional polarity.

I did the same in that house with the old EAW non-powered wedges and the old cabs (KF400s, if anyone remembers those meat locker things).
Talk about the bad ol' days! (and considerably off-topic, I know. Sorry!)

Just think if they had decided to at some point change the older'ish driver models still in production from negative to positive and keep the straight between the two different eras in system inventory!

I always considered the 2445 a nail shooter!

Attached a couple picts of newer JBL's and the polarity labels.

I had a program for the cinema market to recone 2245’s as 2240’s because of the failure rate and deterioration in a cinema environment. Fortunately, the baskets and motors were the same between the models.

Actually, the 2206 (12"), 2226, (15") and 2241 (18") are still the old JBL convention ("positive voltage on the black terminal produces forward motion on the cone").

I stand corrected. I'm with you in 'damn, I'm glad I don't have to keep up with it anymore' either. But how do you wear out a Cricket? I still have my original one, but I'm not sure where the disc is -- I've had the test pulses loaded on my Ipods and phones for ages.

They travel and would get dropped or mud-handled, one set was lost when a kit box was stolen while on a show. And the switches would wear out.
I had the models that came in two units, a sender and a receiver/reader. It never occurred to me to load the pulses to a CD or my phone. Cool idea.
Galaxy is still good about selling the replacement switches for quite a reasonable price.

I'm just realizing that it wasn't the Cricket that came with the 'send' signal on a CD, it was a Whirlwind product that did that. The thinking, I guess, was that a CD player was kind of universally available, which I guess was sort of true at the time. I made a copy of the CD as soon as I had that capability and put the original away... somewhere.

The Whirlwind signal was kind of cool in that it pulses in 3 click bursts with two positive 'clicks' followed by one negative one. So the checker displays 'green-green-red' with an in-polarity signal, which really does result in a high confidence measurement.

Oh, man, I remember the Whirlwind unit. I've seen them in use.

I always meant to get one, just never got around to it.

As do I

I'm not criticizing anything except the factual statement you made that the 2226 response is 30Hz.

Factually it's not, no matter what you believe. It will be exactly what the math AND JBL themselves predict. In your enclosure, it will be over 10dB down at 30Hz and your justifications, arguments, wishing, faith and beliefs can not change this.

I spent almost 40 years mixing FOH and as an SE handing national and international touring acts I have used JBL products extensively, and have designed products with both the 2225 and 2226 drivers. They are great drivers imo, but they will not and can not do as you claim.

I don't blow smoke.

Agree completely. 30Hz is the realm of 21 inch Eighteen Sound drivers in huge cabinets. No speaker is going to put out appreciable audio below Fs (regardless of what Bose tried to do with those hyperpriced little wedges with 9 car-door speakers in them) 2225s and 2226s WILL give you a good punch in the stomach, however. And Happy New Year. Changed my avatar.

I have Cricket as well and this got me to thinking, would a recording of the "Cricket" still work as the test source?

I normally use mine directly connected to the cabinet driver inputs, made up a Speakon connector with tails to plug into the speaker out on the Cricket.

That would an interesting test to find out.

And yes, we have a few of those Speakon- to-1/4” tails, NL4s and NL8s. Been very handy over the years.

Just be sure the cabinet isn't parallel connected to an amp
