The UK dinner thread has some post about adjustments I made to Rich's 4345s.

I summary,

1. Correction of the right hand mid L pad wiring. This out of phase wiring error resulted in imaging issues and a spectral balance issue out of the horns

2. Alignment of the enclosure locations relative to the side walls.

3. Calibration of the L pad for zero (0) of the mid, hf and ufh pad markers.

As installed the mid was -1 low, the hf and uhf were +1 above reference (0) in the flat postion. I used a cd with spot sine wave frequencies at about 650 hz, 4.2 khertz and 15 khertz and read the levels of the meter by deducting the relative (0) dba position from the full scale postion on each L pad.(-4 uhf, -4 hf, -3 mid).

The result is a completely seemless transition of the drivers and marked improvement in imaging.

So finally we've done a good job!

Well now, maybe Rich will cease thoughts of alternative speakers, ferhellsake!

We tried to warn you Rich, these 4345's are not "plug and play"...

Nice job Ian!

Yeah Bo, they never were, that's for sure.

Having had the time and opportunity to compare the latest with these old large format Studio Monitors I have to say that it is my opinion that one has to spend a whole ton of money to beat them after they've been tweaked with today's ideas.

Just found this thread and im amazed. Great craftmanship from input terminal to 2405 slot tweeter. Wich i had the skills. Oh well..ill just have to settle with my JBL Power1222 sub project. Gonna post pics when i get the cabinets.

Would love to hear your setup if take a trip to London in the future. I Live in Norway so its not that far....

Best regards Tim

Hi Giskard,

Nice to see you around.

I said (exactly) as much to Richard coming back on the train from Windsor last night.

For me there is only one jump ahead and I can't afford them.....

Bo's system is working really well too.

For me the sun rises and sets with these (complete) 4345 based systems when they are done right!

Ian

Bo's system is working really well too.

What do you think of the TAD's?

[richluvsound]

Giskard,
thank you for the 2307's

Rich

[Ian Mackenzie]

What do you think of the TAD's?

In Bo's case it was impressive but Bo has done a lot of improvement elsewhere in his system. More resolving power and depth than the stock vintage JBL drivers.

However I hear they are NOA from Tad. I guess Bo got lucky.

I would like to hear Sub's modified 2307 with 2435 Be some day.

Giskard,
thank you for the 2307's

Rich

Sure. I'm glad you ended up with a really nice system.

I would like to hear Sub's modified 2307 with 2435 Be some day.

Yeah, I'm anxious to hear what he has to say about them as well.
