Walter M. - It took me three months to realize that F.U. on all of your notes stood for Felix Unger!

You guys remind me of this scene.

Hey Mark,

are this the final Parameters of the Woofer No. 6? I just bought a pair of those in Europe, Germany. The local distributor provide some different data:

Fs 39,51Hz
Re 7,5 Ohm
Vas 34,50 l.
Qes 0,456
Qms 2,9509
Qts 0,395
Sd 137 cm²
Mms 12,29 g
SPL 88,71 dB
BxL 7,0858

Did the european market receive different samples?

With kind regards, Alex

Hello Alex,
I think you bought the drivers from Blue Planet Acoustic? They do their own testing which is NOT anechoic, publishing their own data without any consultation with me. I recommend you follow my anechoic LMS data.

Blue Planet Acoustic are no longer my main dealer for Europe.

Many thanks
Mark.

Hello Mark,

thank you for the reply.

I didnt buy them at the shop you mentioned, but I know they have/had such woofers...However, I'am going to use your data. (Btw, what do you think about a closed box design with a lift in the low frequences via DSP ?!)

Blue Planet Acoustic are no longer my main dealer for Europe.

Why ? Send me an PM if necessary.

With kind regards, Alex

Hi Alex,
Thanks for your support. I think the re-seller that sold you the No.6 woofs will have been supplied from Blue Planet, your re-seller using their data.

I've enjoyed my time with Nick and Thorsten at Blue Planet. They are nice guys but Markaudio is growing; Its time to take a fresh look at how Europe Diyers are best supported and supplied. See this thread:

European Distribution - your opinions, ideas

Thanks
Mark.

I'll have a look at the thread

or you could put them in a smallish closed box (qb=0.9) and add a 470µF series capacitor

Hello everyone, I just quickly flipped through the last 10 or so pages.

Is there a first order design idea yet using a tweet and woofer ?

I second that question. (el166 and ert26)

Is there a first order design idea yet using a tweet and woofer ?

Well here are a couple of my 2-way designs using the Woofer #6 (EL166) and Tweeter #3 (ERT26) and using a first order crossover. The second larger floorstander using 4-woofers started life using the T#3 but with the gain in SPL of the 4 series/parallel wired woofers raising to 93dB/94dB it was just a little too much to ask of the excellent 1" silk dome tweeter. So I now use the Monacor ribbon tweeter. The midrange from the floorstanders has been favourably likened to that of my Quad63 ESLs. A testament to Marks design of the woofer.

These drivers are excellent performers as a simple 2-way speaker.
