Building process - The loudspeaker 1

I’ve had a similar idea. I’ve realized it has to be able to expand infinitely to work perfectly, as well as being massless. Just shout when you finish that one 😉
Why?
The Sd and Xmax of a massless sphere (MS) only needs to match that of conventional drivers.
A 6 inch diameter MS will have a 4 times greater surface area compared to a 6 inch cone (A of sphere = 4 * Pi * r squared Vs area of cone = Pi * r squared) so 6 inch diameter cone so in fact would only need to move one quarter as much as a 6 inch cone to generate the same SPL.
 
Hi Noam

Again very nice craftmanship !
I wonder how you will like the 12n630 after being spoilt by the 18n862.

Talking of the latter: Do you still use those in the closed corner-loaded boxes ?

Hi Charles, thank you 🙏

The 12N630 do stuff that the 18N862 couldn't do and vice versa.
I get better slam and punchier high bass from the 12N630. I think that it integrate better with the 10inch midrange. But the big foundation the ported cabinet 18N862 provided is gone. It feels a bit more like a big studio monitor, very very precise, and scary real. Lots and lots of details and nuance, great depth as well.
I have yet to try the baby TL2 with the subwoofers. I think that those subs wouldn't have a lot to do...

Yesterday I have polished some messing I had. Just to add extra bling, I still need to find someone who can grave on it. This new shaper origin tool would have done it but the price is brutal. Still, would come so handy!

Perfect integration but do corner-loaded subs work? my concern is that you will need to castrate them in the dsp to prevent booming sound, to an extent that they no more sound like 18” drivers.
The trick is use 4 of them……smooth as silk in room response as now the sound waves are fully coupled to the room. The goal of subwoofers are to excite room modes and nothing else.
 
Thank you so much.

I feel like, regardless of how many instruments there are, there is a speaker dedicated to that individual instrument.

My friend and I listened to them and it is beyond our wildest dream.

This is what my friend wrote to our local group.

“Just got back from listening to them. Fanfare for the Common Man sounded better on them than on the Wilson Chronosonics we heard at Innovative Audio. Amazing!!”

I used inch and three-quarter bamboo countertop for the Face. The sides are inch and a half MDF the cross bracing is 1 inch MDF the cabinets weigh 190 pounds empty.

I used the Mundorf Angelique wire. The one with the silver and gold with the copper.

And the angels sing 😁🎶
 
I was so relieved when they worked.
Oh my goodness, I have never built anything like this before.
I could follow a schematic to build a crossover. But I don’t really understand what’s going on. I could’ve plugged it in and nothing would have worked at all.
For the sound like this is such a relief.

The other aspect, I did not think I was going to be excited about is that I got to get rid of all of the boxes that all the drivers were in. To have that space back was a relief also.

I’ve been building these for about two years
