I realized once again that air recording is not useful as a reference unless the equipment used and recording conditions (microphone, installation distance, etc.) are disclosed.

Thank you for introducing your work.
I'm more interested in the tennis racket than the audio equipment.
Does the racket vibrate or resonate?

Nice, both the ears and the racket are hitting the sweet spot perfectly!

Hi ChrisABC,

The price of the LignoAudio SP-50SS is too high.
Will anyone buy it?

 

[EUVL]

But can DIY ?

😊

[ChrisABC]

LignoAudio SP-50SS- (buy it? They sell it, DIY'er won't buy it.) 297,000 yen

DIY, another cabinet option for small fullrange drivers.
(notice: how big those speaker terminals look).

 

[Pierrick59]

is the chp 50p mica is the best sound of all your minispeaker that you have made?

 

[nandappe]

I am losing my treble hearing with age, but I can tell the difference because the presence or absence of treble affects the mid-tones as well.
I feel that sound pressure up to around 12 kHz is necessary.

 

[nandappe]

But can DIY ?

Making a pentagonal pillar is not difficult, if you can cut an angle.

Sorry, I posted #53 by mistake.

TangBand W3-1878 > MarkAudio CHN50P mica = Fostex FF85WK = SPK Audio FR03E = FaitalPRO 3FE22-8 > other 3" driver

CHN50P - Nice Vocal Quality
FF85WK - Well Ballance & easy use
FR03E - Well Ballance & Low Price
3FE22-8 - Super Natural Sound

At an off-line meeting with my audio friends in January, we agreed that "3-inch full range is best for listening to female vocals".

 

[EUVL]

Can you kindly post the drawing of the above ?

[cracked case]

Just received an "AKLOSPY" USB speaker, it's NOT the 300 yen speaker, it's trash.
Just a cheap look alike. Only one 8002 op amp (2 watts) and the drivers are dreadful

 

[EUVL]

Well, a friend in England ordered the same Audiocore speakers as I did.
He confirmed my positive impressions after replacing the USB driven electronics with TDA7266 chipamp.
Only need the enclosure to boost up bass.

[Klimon]

Only need the enclosure to boost up bass.

What are you / is he using as enclosure?
