it's true because you need more surface to reach deeper, even if nowadays we can have small drivers that moves a lot that doesn't mean it produces sound. We can see people using "low frequency mode" on their JBL that deactivates the crossover, it moves more, even at 25hz but we can't hear anything
THDS that’s because the driver doesn’t couple the sound to the air anymore But this doesn’t mean that you need more surface area for deep bass I just explained why that’s not the case
@@speakertoni2680 so which parameter does lower the frequency ? is it really just adding mass to the cone ?! or choosing a cone material that doesn't cancel himself at lower frequency by deforming ?

Henry47 thank you I’m not sure when, it takes longer than I expected especially because I’m trying to finish multiple speakers But I’m trying to at least show a bit more about these speakers soon
Nice elaborate 🤙 Btw, speaker *efficiency* is not common name for the dB parameter of a speaker driver. From the spoken values I would presume you were talking about *sensitivity* parameter. 😉
High excursion small drivers are usually less linear when they start nearing extreme amounts of it, but still what you say holds true. I've built a battery powered 3.5 inch tb subwoofer that digs below 50hz in a box with passive radiators that is less than 3L. It's fs is lower than the one in your video at 45hz but tuned a bit more boomy in that area for more output. Great for casual listening but not so much for party levels.
aber size matters. always :D auch bei speakern :D physics! zu midneest bewegt mehr oberflcähe mehr luft. kalr ist der HUB noch entscheidend also "excursion" aber ein großer treiber mit hoher "excursion" zerstört jeden kleineren vom bass(von der lautstärke locker) bei gleichem AMP
Wie in Video erwähnt werden hier wichtige Details vergessen. Was willst du mit einer 12“ Membran und 2cm Hub wenn die Parameter keinen Tiefbass erlauben?
@@speakertoni2680 ja wie gesagt, wenn dann gleicher hub im vergleich zu nem kleinen membran. dann hat der kleinere trotzdem ekien chance. kann der kleinere ja nur durch hub ausgelichen um irgendwie mithalten zu können. also ich mein damit nur, das generell größere treiber eben auch mehr bass erzeugen können auf hohen lautstärken. sieht man ja an den ganzen tragbaren kleinen bluetooth speakern, dass die alle kaum unter 50hz kommen und bei hohen lautstärken kaum bass reproduzieren können... kaum hub und kleine membrane halt. leider ist das physikalisch begrenzt. würden mir zu gern 25 -45 hz bass auf über 100 db wünschen von nem tragbaren bluetooth speaker der nicht zu groß ist, aber geht wohl nicht. not today :D
Ja klar, wie gesagt sind die Parameter von einander abhängig Du kannst 25hz aus einer BT Box bekommen, aber dann so leise dass es nicht zu benutzen ist Oder 100db, aber dann so dass kaum Bass da ist Man kann leider nur eines der beiden haben haha
Wichtig ist, dass der Bass auch hörbar ist. Bringt halt nix, wenn ein kleiner Treiber Bass wiedergibt, der aber zu leise zum Hören ist. Gibt ja ne schöne Grafik dazu.
I have a question about speakers in general. I was told for the same speaker, having one finished in wood veneer will sound better than the one in piano black finish. How true is it?
Isaac Chew if it’s the same cabinet material on both speakers you should barely notice it Maybe the walls of the speaker resonate slightly different with the wood veneer but it’s not a huge deal I’d say
Please upload more videos like this. Technical information with real life application experiences are valuable. thanks
Nice to have a new video! Looking forward to more about your own speakers and reviews of others.
Looking forward to more of these technical, educational videos.
Also hope you'll show step by step design- and build-process of new speakers. :)
Hi Tony, haven't heard you a long time, glad that you've came back.
Pro tip : you can watch movies on flixzone. Been using it for watching loads of movies lately.
@Jeremias Patrick Yea, been using flixzone for since december myself :)

THDS parameters like the resonance frequency, the qts or the magnet strength for example are important

Depth and SPL at a given frequency are two different things:

@Speaker Toni great job & when are you going to start sealing your speakers?
Henry47 thank you

plz compare the phantom reactor with the gold phantom.
I want more videos of the phantom reactor.
You should really look into Hoffman’s Iron Law.
I mean you just have to look at headphone drivers. They can be 6mm and reach 5hz

Zensor5 ax. Please~
weißt du was zu neuen jbl speakern oder allgemein bluetooth speakern die dieses jahr erscheinen? irgendwas spannenedes dabei?
Hab mich nicht großartig darum gekümmert
Ich glaub der Flip 5 soll rauskommen
@@speakertoni2680 okay gut zu wissen danke!. aber keine boombox 2 oder was größeres?
Nicht dass ich wüsste
