Some think that only a slimm speaker can throw a soundstage that makes the speakers " disappear ". A good example is the ProAc Tablette. That works best in the nearfield i think.

. I mean i made my income with slim speakers so i should not complain about them.

Some would claim you created the trend for slim speakers! I was very impressed by the Avanti back in 97, but was outside my price range.

 

[Joachim Gerhard]

Yes, i did. The original Avanti was introduced in 1989.

Those were the days... 😉
I still have my CLIO system on an ancient computer, but my LSPCAD license has long expired...

Interesting wideband concept. Did I still have speakers, I would do something like what you are showing.

 

[Joachim Gerhard]

This is the frequency response of this speaker. It is a 4 way.
Forget the response under 200Hz. It was a gated maesurements in the lab.
I just show this speaker because it is wide and still images well correctly set up.

Dave, like.

Smart cabinet design - of course what you do inside that sort of shape makes a great deal of difference. (I'm sure you know that...)

Pretty too...

Top is an aperiodic midTL, bottom is sealed.

This is going a bit off-topic Joachim, sorry.

OK, here we go...

Here are pictures of my wideband driver.

Do you think that there would be a significant advantage to using Panzerholz at least on the front baffle compared to bamboo ply?

 

[Joachim Gerhard]

Yes, but it is not an easy material to work with. On the other hand the cabinet as is sounds great. Much better then any system i heard at CES last year.
OK, you know that statement from Linkwitz.
I have the advantage that i attended 300+ shows in my live and i was in the rooms of virtually all famous revievers in this world.
In Germany we say : It is not eaten as hot as it is cooked.

 

[critofur]

Certainly a better hifi than i had at that age 🙂

I actually have never found a system as enjoyable since, as the one I got when I was 8 years old from my dad - a Dyna tube amp, Gerard turntable, and a pair of "db" 8 inch paper cone 2-way "book shelf" speakers with paper cone tweeters (alum. dustcap on the tweet).

Listening to that system was fun and never fatiguing - if I try to listen to a pair of high end B&W driven by premium monoblocks with a digital source, I have to put my hands over my ears and leave the store or I'll get a headache...

Here are pictures of my wideband driver.

Hi Gerhard

Could you please share more information about this driver? Any off axis measurements available? I'm looking for a full range 8" driver that has decent uniformity around the 0° axis.

Thank you.

Hello Gerhard,

Any further news about your driver?

Hello Gerhard,

Any news on your driver?

 

[Joachim Gerhard]

I made the driver availlable without crossover and building plan. They cost 800,-€ per pair.

 

[ponger]

Where can the drivers be purchased?

Thank you
