Try/review SPICY TL software. Much better and easy to use. Also very accurate simulation vs actual results.

I found that I lost interest with eliexpress because there is poor information and lots of real garbage they sell. Yes the rare surprise of a good product. Ayima t-9 good. Avoid buying from them in my future.

WoW ! Just what I was looking for !

I like to port a little below audibility for a little more punch, no cancelation, a little more efficiency, and a Lot of cooling to the voice coil.

Hello ... my speakers are 3ohm, my AVR SONY 7.2 channel 8-16 ohm , whats is solution ? Can increase impedance with resister from 3 ohm to 8 ohm is safe ?

Can you explain how to do a tapped horn?

Great video. May I say, when you were putting on the 'akshually' voice it sounded like winnie the pooh lol.

Hi, I was trying to replicate all step by step and it fail to show up in windows sound panel. Now I have checked all wats wrong , and apearantley - on schematics you showed only three cables connected to stereo jack, while on video you have four cables going out from stereo jack! Please help to fix, Thanks

based on my experience, slightly more powerful speakers, with lower qts, such a system misplaces the resonant frequency of the speaker about 10 hz higher. I wonder what it comes from?

I don’t see a link for your spreadsheet. Where is it?

Excelente resultado!

The 6 inch is the exact same speaker they make fake focal speakers from they just slap focal decals on it and charge $400 plus

Check those aluminum foot plate on the circular saws....

In this comparison video, it would've been best to also put both speakers in the 50L box, in the clam-shell configuration, and then measure it to show the big increase in dB that is achieved at the 20Hz-60Hz range.

I built my first double 12inch box last week, I wanted to put an 8 inch aero port but the one that I wanted to buy was actually more expensive than all my material put together so I bought an 8 inch pvc pipe which worked out to 80% cheaper. Next step was flaring the pipe which was done easily using a gas stove. Box specs: H - 350mm W - 920mm D - 380mm Took it an SPL car show today and did a 147.4 db's @ 55hz

Great video!!!! Thank you a lot!!

I haven’t understod WINisd entirely. Is a ported box of lets say 16Liters , is that WITH the port or Without the port? So one and the external volume of the port on top of the 16L? Thank you

What a great video, editing, time spent and all the work with the boxes! Helpful and informative!!

Can I make it portable

He said ported boxes are crap hahaha

Thanks!

would be interesting to see a `small` plugged ported box freq response and db. ive done some testing with different density plugs with good results. so a happy(?) medium of sealed and bassreflex

A tip, don't use screws, high end enclosure don't use screws.

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!

Gracias señor por compartir su conocimiento…! Saludos desde Quito-Ecuador 🇪🇨👍

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 ???
