Why did you private the old video? At least set it to unlisted or something. I was using it for reference

How many watts a tweeter must have for a speaker 240 watts

Hey your reference calibration resistor is a 10watt27ohm but all I have is a couple 1watt resistors. I can parallel a maximum of 5 will this be safe ?

Dude coat the inside and outside with raptor liner, and measure again. And test out sound quality before and after dammit man! You just gave me blue balls like a mother fuker

Different mass = different Vas, how much mass needs to add and why? Are you try to compare different masses and results?

Yeah! Some people say taking a shower once in a while is superfluous! Damping might be seen as the last piece of a puzzle in speaker design but my experience showed me you can really fix some resonances and bad behavior by a judicious use of damping material. Great video!

Audiophiles use music to listen to their equipment. Real music lovers use their equipment to listen to music.

W hat if one cone from a sub is removed and the coil is directly connected to drive the Cone of the other sub? What would be the difference? Essentially one cone being driven on both sides by two motors

I'm not sure why you got a larger than normal surge of power when you reconnected the battery. Did you maybe leave the battery disconnected longer than you normally do? My guess is that the energy stored in the capacitors in modules all over the vehicle became discharged and when you reconnected the battery you got a massive surge as those capacitors recharged. Amplifiers do this all the time when they are disconnected from power. Most amps have a small discharge circuit that allows the capacitors to bleed down. When reconnected they might have a brief surge of current of 10 or more amps before settling down. If the DSP uses a capacitor to save the basic settings, not the big presets, then it's capacitor may have gotten drained and the DSP reset itself. That would be my guess as to what happened.

The only thing I don't like about Audison are their DSPs. They're very temperamental. They might need to be powered off when connecting to the laptop, then booting it up, ??? Also, your volume was down on the DSP because of the new firmware update, not because of the power surge.

Love the channel man. Would love to see a similar video with a shallow mount sub, what's the best box etc

14:15 waiting your next video!

is there any cheap spl meter? (lowest priced one please)

Hi! i like so much your vids! i´d like to ask you something...what brand of dsp do you recomend and how should i connect it in my car? i´m looking for a dsp "good, nice, and cheap". My car has an amplified bose car sound system (stock audio system) and i just want to connect a subwoofer with amplifier. thanks!

At least it was the least expensive of the possible problems.

Hey, I'm just curious. I don't have a BMW, but I wonder what your thoughts are on an underseat woofer? Is it a subwoofer, or is it as a midwoofer? Any thoughts? Thanks as always.

Mulțumesc pentru videoclip,bun și util!.

came stock with 4 inch drivers and no tweeters??? damn My brothers E46 came stock with tweeters and 6.5s all around

Can i use rca input instead?

can you do a video on designing and building a rear loaded horn

hmm, would 0.37 be okay for a sealed box?

Can that change under high power?

Now try the methods with an 18 inch woofer and see which ones are still viable 🙃

I have a ported box tuned to 34 hz and a DB WDX12G2.4 with a skar audio RP2000.1D in a 2005 Scion xB. I just can not get my tuning right do you have any tips for me? Thank you. New at this

Salut,Cum pot sa iau legatura cu tine? Am nevoie de un proiect pentru o cutie , contra cost normal

Behringer mic has a calibration file on the website, not perfect as it is a generic for all ECM800 mics, but would probably take it so much closer to your reference ???

too complicated

For Vas, I use metal or ceramic bowls, they are very sturdy, very easy to measure internal volumes and the hemisphere shape is ideal as an enclosure. I stick a sponge between the bowl and the speaker and is very easy to secure any speaker with scotch tape. I used this method up to 12 inch speakers.

Dayton Audio DATS V3 is well worth the investment.

Man this got me to subscribe. You explained this perfectly well in a simplified manner. Hats off to you.

Great tips! Another tip is when you have to cut two identical panels (I.e. front and back panels) tape them together with double-sided tape and cut them together.

Oh I don’t think your 3x math works. You need to find the offset required and work from there. 30mm template and 10mm bit is a 10mm offset…any other size template and bit even 3x multiples is going to create a different offset. Ex 15mm guid 5mm bit is a 5mm offset.

good work

I had some Audio Pro floorstanding speakers that had the port down firing, and it was just a two way, so one small (5-6" I think?) driver and a tweeter. It had significant sub bass output, good below 30Hz.

Oh I’m guessing get the spreed sheet with your course?

Awesome video for sure

So, i like the fr flatness and consistency, but i would want direct control of the sub as that doesnt even resch as low as alot of small bluetooth boomboxes. Tribit stormbox blast, jbl boombox 3, dbsoarsf29max, wking x20, all either smaller than this or similar sized and play to ~90db hitting down to 45-50hz, and well over 100hz with their dsp rolling it off after 100hz

Hi, can I ask if you sent your speaker measurement results back to Aiyima? I was thinking this would be beneficial for people looking into purchasing speakers in the future and get Aiyima to 'lift their game'. Cheers J

Heck yeah

Just before discovering this video I had ordered the one you mentioned as interesting on the site. That one with a "gold" and a black variant. I took the black one. We'll see. My primary use is to play bass 🎸 on it so I don't really have the same needs. For instance low E on the bass is 42Hz and there's no reason the speaker would ever encounter lower frequencies.

I wonder why there are so huge differences between measures and data sheets displayed on AliExpress. One option is that they simply cheat and make data sheets that correspond to the speaker they copied and not the ones they produce. Another worse option is that it is a lottery. Maybe they actually measured one speaker they've produced but the quality of production is random and if you buy a second set of speakers they'll be totally different. It's worse because if you want to make a stereo system you'll never have left and right giving similar sound. Maybe they've tested 10 speakers of a model and they kept data from one of them that seemed commercially better? If so yo have 10% chance to get a speaker matching roughly the dataset?

Direct and to the point, you just got yourself a subscriber

I can use the line in of the sound card instead the microphone input? These are always stereo

One of my prefered videos in your channel

I don't measure my speakers - I listen to music on them.

AJ: Free air measurement first, then attach the woofer it to the closed box and measure again, with the closed box option?

In REW & VituixCAD, you can also try the double mass added method. There is a paper that show that it's help for VAS precision.

In olden days, some people used large open cardioid baffles, the cardioid shape has a nice even responses being either equally good, or equally bad across the board. It does need to be rather hefty, with size also a factor, iirc the circumference would be the wavelength of the cutoff frequency of the baffle. They also look cool, like huge lilypads.

Can u suggest a passive crossover for this boombox please I cannot buy Arylic in my country
