We find John here in an advert for Dolby circa 1970.

I share the reserved first-look thinking on this piece but if it can pry some folks away from the bluetooth earbuds to actually investing in some worthy speakers and a chair in their space filled...

If the stock crossover remains unaltered, the woofer-green and the mid-white connect to driver red terminal. The LE-25 tweeter should have quick-connect terminals and the red wire from the crossover...

Very good idea to listen in your own room. The only disadvantage in the aural presentation I noted was some amount of stratification of sound top to bottom. In other words, the image may vary a bit...

Very nice craftsmanship. Did yourself proud!

I sure do like those woofers. They are very tuneful and don't shy away from a little added gain once in a while.

A hybrid of Option 2 & 3 would be more of interest to me. A unit configured as with Option 1 would compete as just another Ashley or Rane competitor, albeit with much better component parts. May be...

JBL models of this era (generally) wired the leg from the crossover to the drivers in a consistent configuration. The solid wire to the driver connected to the positive terminal of the driver, the...

You have to choose one woofer for optimizing the enclosure size and tuning.

So, you get one woofer operating in an optimized environment that may not work well for the other woofer.

You will...

The reference to 4335 is a typo. The 2-way 4331 and 3-way 4333, along with the 4315, are models Greg was associated
with early in his tenure.

The Sovereign isn't likely to be in many folk's listening experience making it difficult to comment appropriately.

I am no different. The Sovereign by reputation was meant to offer up just about...

I hesitate to go down the driver polarity path on this but should add some background on your situation.

Agree that the terminals, male and female, on the mid driver are reversed according to the...

I have to think this a modest understatement! Exciting endeavor none the less.

A hammer on the turntable?

You mean folks in the day could figure out that this was just ad copy for effect and you don't have to provide all sorts of warnings and disclaimers in tiny print?

Have not used his services for while but Daniel at Audivex is a good start. No website but still listed on JBL support page.

Typo, yes. 10uF with a low signal level just long enough to set the piece.

You can apply a test tone (1,000 Hz with 10mF capacitor in series) to the tweeter. As you lower the diaphragm assembly down near the pole the coil will start to pick up the signal even if it is not...

Are these PRIME eligible so I can get them Tuesday?

You will get interference with drivers separated in distance that manifests in lobing and radiation tilt. The acoustic response will vary depending upon things like crossover alignment, the number of...

Yes, I would to hear the story on the woofers!

PBN speakers seem familiar, for some reason. Website mentions charge-coupled xovers and Symmetrical Field Geometry woofers. https://pbnaudio.com/m25-loudspeaker/

Wonderful execution, Widget. The units look large but the tapering makes an illusion of smaller enclosures. Must be very nice to sit back and realize how those man-hours paid off.

Did you source...

:p

Were these people larger than life to us because they were way more visible above the routine of life in the 60's and 70's? So much more noise and distractions in life these days, seems to me.

Calling it a scam may be an opinion, yes. But a barbed opinion that comes off like trolling. So it didn't work for you. I get it.
