Hi Rob,

That’s funny.

My post needs to be read coherently and then related to the links. I’m not taking sides. I am providing clarity on where this online nonsense by Popup YouTubers is going....

I’ve heard Rob’s set up with the E-145. It’s definitely a fast driver & perfect for mid base.

Speaking of reviews Erin has pissed off loudspeaker manufacturer Tekton.

I am posting this because...

Hi Rob,

That makes a lot of sense. Glad you elaborated. There is no one size fits all. Not really.

Its really useful to understand how people approach the practicality of setting up a System....

Efficiency + Displacement = Bigger more real listening experience

Continuing from my last post -:

This whole business of measurements reminds me of the measurement race between amplifier brands back in the 1970’s. As we know what they were doing wasn’t well...

I agree in that measurement approaches have advanced. To my mind it needs simplifying down from to how well a loudspeaker translates to a nirvana experience of a tune at home. It’s the inverse of...

Hi Rob,

Thanks for your thoughtful response. I agree it is a mixed bag. I was purely looking at JBL Consumer on market share.

I think they have kind of left a few direct radiator systems...

So where does this leave the loudspeaker hifi enthusiasts?

The more astute and adventurous are well aware of the significant benefits of going the diy loudspeaker route. The challenge is designing...

The reality is that despite Harman’s research they have only a very very small slice of the consumer hifi loudspeaker market. So is Harman’s research being correctly applied?

The JBL profile in...

Hi Rob,

I thought that was an interesting vid clip putting aside Erin’s un informed understanding of what we take for granted.

I didn’t have time to watch it all the way through.

The call...

It doesn’t say much for those Altec 604’s…… the 4310-4311 were designed to mimic. Back in the day with bands including the Who and the Beatles it didn’t matter what it was monitored with ..Lol.

Hi Phil,

Hey l acknowledge your thought & I appreciate your sensitivity.

No offence taken or meant. I now get your lens.

The problem with this medium is the lack of sentiment.

A JBL 4345 tip from Ian Mackenzie 4343 4344 4345

Set up your 4345 active bi amp crossovers as follows:

Woofer to midrange Linkwitz 2nd order low and high pass @300 hertz with reverse electrical...

It’s amusing that while both Erin and Greg decided to keep it informal and see where the discussion went you guys have nothing more important than to pointlessly dissect it.

They both correspond...

I will see what l can find out.
I’m pleased you could see the positives and l agree completely. It was an informal chat.


Greg doesn’t mince words and gets straight to the point. I think that’s...

Ian,

I did not spend any time active on the...

Greg suggested the following for the 4367.

I’ve relayed it to the 4367 owner in Italy with some pointers on obtaining the woofer voltage drive using a Focusrite Scarlet USB interface. It’s up to...

I have a follow up on Greg’s system below for you guys. Greg now spends most of his time on his house boat enjoying his retirement. So snippets about his system are few and far between.

Hi Ian,...

Hi Todd,

I am sure your thoughtful and generous contribution will be much appreciated.

Thank you

We will look at this more closely.

Well Good luck with whatever it’s your about.

The problem is you’re now resentful and recalcitrant to anything you don’t already know. Giskard had the same problems although you tolerated it...

If you want that as a reference for comparison then it needs to be validated. Otherwise it’s misleading.

On the basis of you’ve posted if it was true then why bother with beryllium??

Hi Rob,

Under what conditions did you test those drivers ?
Were those measurements gated and what distance?
Looks like you smoothed them 1/12 octave.
