Tror hele byggeriet render op i 3000kr. Hvilket er pointen 🙂 alt er DYI.
En 6mm cnc skåret stykke copper fra en virksomhed koster det samme hvis ikke mere 🙂
Yes, it was also just to show some "crazy fun".
I found a shop selling up to 5mm copper. I dialed in 10 x 10 cm (5mm thick) and the price incl. tax was about 70 Euro.
DAD products are also a bit pricey but this new speaker they have developed has an ok price tag and it is even incl. tax:

I should not "pollute" the thread with this.......but 96 dB and 8 ohm......a nice speaker for the amps we build in this thread.
The name "Miracle" is also a good choice thinking of the price.

21" woofer - any - represents significant load to any amplifier, due to unavoidable high moving mass
so, not necessarily extremely potent amp, but one with loads of current at disposal
call it damping factor, call it dynamic potential, call it Berserking
and all that, relatively low power allowed only if speaker designed to all drivers being awake on relatively low SPL
plenty of efficient speakers around, but not sensitive enough, demanding higher SPL to get all drivers in line

i have dali helicon 400 mk2s and theres no way i will ever replace them for those 😀 they look terrible.
I think I would volunteer to give them a try......especially for the price 🙂
But I have to admit that bas response is too "boomy" for me. Then my OBL15 has much better and "drier" bas response 🙂
Probably the Youtube sound is not representative for a live experience with the speakers.
Or maybe they just need a Pass or ZM amp design to drive them.
But ZM says we have too little current 😕

Papa's XA25 will have all the current needed for any 21" ....... heck, maybe even Babelfish M25 will have
but, as far as I know, 21" drivers I would listen with my amps are rare as hen's tits
don't need that power, don't need that SPL for which majority of these are made
heck, rather would build something with old Hartley 24" ........... or was it in Yore maybe Diatone, by memory having cone of 10 feet

It must be for another thread some day (not to hi-jack this too much) but it seems the speaker impedance curve is not enough to look at when pairing an amp to a speaker. E.g. if the above speaker is a straight 8 ohm line without any major dips how can you know it will need a lot of current?
Now I don't know the above speakers curve so it could have some major dips at the low frequencies.
SPL curve is of course also needed.

I didn't said anything about these speakers, just wrote my thoughts about speakers compatibility with amps of smaller power
moral of the story - my layman logic - I would rather see Mms figure than impedance graph and ...... don't forget - issue of low level sensitivity ( not efficiency!) is really important in same context
one thing is having 2 or 3 way speaker intended for home use and another intended for PA, power levels are completely different

Dayhm mr. Pass himself likes my diy amp. I am actually humbled. And here i was thinking it was just somthing "meh"
I was putting togeather.
