Salut. Felicitari pentru cea ce faci. As avea si eu nevoie de ajutorul tau daca se poate. Ai putea sa imi lasi un email ?

Fantastic video. Great explanation. Keep it simple is best. Learned quite a bit. Thanks

Beautiful! Your gluing skills are top notch, as you mentioned. Specs say it runs on 12v-24v. Wonder if it could be battery powered? What amp hour rating could give us 4 hours of play time at 50% volume? Tha ks for the build video. It really does look and sound nice :)

i would love for an updated video, but using vituixCAD2, simulate the whole speaker, enclosure, diffraction and crossover. and see how accurate the simulation is

If we wanted to use 2 subwoofers instead of 1, how would we go about punching the numbers in the spreadsheet?

15:30 is all you need

Excellent video. Very informative and well explained. 👍🔊😊🎶

Thank you, it helps me so much.

Thank you for a clear, easy to understand tutorial. Yet another thing I will be wasting, errr, learning and using my time wisely.

The hole in a sub has one purpose - to make dumb people ask … What’s the hole for ? 🤷‍♂️🤪👍

Well done and thanks for sharing.

It's simple Americans always scream "usa made " reality is the USA has absolutely no foothold worldwide. China has and IS THE KING in terms of manufacturing, even American brands *choughs* PSaudio, china makes their so called irs v killers running you well past 10k set price . Wake up guys, the gear they sell there is not even copied. Its based of stuff our so called "american and european made " send over there to manufacture for them. The marketing is whack but I've heard a good bit of their drivers and even speakers (Mistral,b&w Nautilus clones) And i definitely can say for the prices?!! Exceedingly good

Nice I have a AS-2000 pretty old school but love it

Ótimo vídeo, consegui aferir os parâmetro TS dos meus auto falantes.

When measuring a frequency response curve, can I determine maximum and minimum limits for a pass or fail judgment?

Since DIY xovers are ultimately tuned by ear anyhow what difference does the accuracy of the mic really make? The final sound is going to be adjusted to taste/room no matter how accurate the mic is. You're going to end up with the same xover topology no matter the mic. Only with a poor mic you will need to tweak the component values by ear. I think for most DIY'ers any of these mics can get the job done.

The best video on this subject! I got my answer why my calculated volume is coming with a negative sign. Now, what should be done for small speakers with Qts value more than 1.2?

Thanks for this tutorial video and the excel sheet ! Can you help me pls regarding the following issue? I was trying with data for a 4 inch 30 watt small sony full range speaker. The box volume was coming with a negative number ! Fs - 202 Hz Qts - 1.23 Vas - 0.78 Ok ... I got my answer from your another video👍 But what should be done for small speakers having Qts more than 1.2 ?

I wish I had watched this great video 2 weeks ago. I just bought two 10 inch woofers for an open baffle project. The Xmax is 6.5. I'm thinking about returning them.

Thank ypu for the video. Just having this doubt, am having a dual klipsch R 121 Sw sub in my home. The gain is about 50 % and avr trim at - 8. Is it ok to cover the port with plugs or using some socks to get some good punch. Mine feels bit boomy some times. And if its designed to wrk ported , any problems if i restrict the air flow ? I knw big brands having port plugs and all. Thanks

I don't build boxes at all anymore. No need. I now only use pipes for smaller drivers and sonotubes for larger drivers. Why build boxes when pipes are easier and can sound even better when done right?

So, birch or MDF?

Really great information, thank you!

Ports are always better. Makes music more boomy.

'xlr needs phantom power to work' Maybe for your application; but far from the general truth. Needless misinformation

Do you know if Audient ID4 (Mk1) can be used in the same way for loopback timing reference using similar analogue cable? I would greatly appreciate your advice as I am confused and cannot figure it out.

Hey,,excellent video, just like I imagined the correct way it has to be!

I've built sealed and vented my whole life. I had a small sports car with a tiny 8" sealed wedge in the back but got rid of that car and had a high excursion 8" lying around, so for kicks I tried a flared T-Line (hybrid of a horn and T-Line) and I was blown away by the low end extension from such a tiny sub. It went into my SUV and rattled the car with only 250w rms into it. I'm a T-Line fan for life. Trying another T-Line again this time with my Solobaric L7 12" currently sitting in a vented box.

I'd be interested in seeing some more 2-way speaker builds featuring well spec'd drivers of Ali Express or another site that you like, that could compete with prebuilt speaker pairs that sell in the price range of $800-$1500.

what is the best glue?

Here you can see why MDF is shit for Speaker Building. This is a Video of a Vakuum Tablet and a 19mm thick MDF Plate on it and it can still hold a sheet of Paper through the MDF: kzbin.info/www/bejne/j4eroIicbpudnKMsi=mQs_jYgZAxeBnND8 Your "Normal" Leakage isn't normal with MDF.

so good, thanks

How to know Le of voice coil?

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
