hey brothah hpw much cost your subwoofer 24 inch ??

I'm new to this. I have a 15" Jensen that response Peet's at 2100hz. When pulling it down it ends up impedance dropping to 1 0hm or below. It's also making a huge trough at the cover point.

any TAD driver

Altec 288c , Gauss 1502

Why is only impedance moving for me when adding compenants to the crossover???? It's doing it on both xsim and vituixcad. I tried my own files as well as files from parts express. I don't fricken get it

We need you back... its been years.. too many years. Hope the addition went up and all is well.

Revisiting this as it is now years later. The guitar example of harmonics is superb, and I wanted to share it with some people.. glad I found it again.

Test results are impressive!! I just got a pair in today but since I got mine from a backstock they didn't come in nice packaging like yours lol

So how can you design a speaker foam/cloth grill cover that will not cause diffraction?

I am going to use this mid in a three way with a Fostex FW305 12 inch woofer and a Scan/Vifa XT25TG30.Crossover points at 400Hz and about 2500Hz.This combination has been modeled elsewhere and should give around 92/93 db sensitivity with a slightly downsloping response.

you have dry walls. use em. literally, just cut holes tomount the tweeters right into the wall. thats an infinite baffle.

Do 6 kHz použijem horn ozvučnicu z dreva aby som získal hlasitosť . Na spektrum od 6kHz hore použijem ešte jeden taký istý vysokotónový reproduktor ktorý môžem zaťažiť viac pretože ho delíme vysoko. Takto získam dvojnásobný zvuk z dvoch rovnakých vysokotónových reproduktorov ale výsledok bude viac podobný zdroju z jedného bodu.

A simple capacitor (6dB rolloff) at 12K would flatten out the waveguide effects and a coil to ground would finish the job at 2.5K. That all being said, we really need an impulse measurement to see if the problem is diffraction or horn loading. Then we see if the time arrival is messed up. Frequency sweeps only tell us about the sound pressure - not what it is made up of.

You need impulse measurements to show diffraction. It is a time domain issue, not frequency response.

I especially enjoyed the review you did of the Viawave GRT 145 with the other ribbon driver. That was excellently done. I also that see you did a basic demo (wouldn't call it a full review) of the Sounderlink Neo 8 AMT Planar. Is there any chance you might be able to do a review of the Sounderlink Neo 10??? And the Sounderlink Neo 3? Those are AMT Planars that a lot of people are looking at, but there are not any comprehensive reviews on them like the one you did on the Viawave.

Hi, congratulations on the project! I would like to know the volume of the box and the dimensions of the reflex duct, I don't think I saw them in the videos. Thanks a lot, Federico

I remember paying 600 for a set of esotec tweeters from dynaudio in the 90s. Always love their tweeters. Now i only run AMT 1a Heil tweets.

Nice tutorial but you are going to fast

Thanks, learnt a lot How much smoothing do you use on the graphs?

wow. Get this guy some views so he can afford to turn on the heat! :)

oh my goodness, no. you did not compensate for baffle step losses. that can only be done whit a shelving filter.

Hello friend. Are you still building systems ? I just meet your channel and I was hopping to be able to contact you. Where are you located ?

Thanks.

Best midwoofers - are those that are easy to work with and simple to filter. Usually these are speakers with a descending frequency response, without any emissions at the end of the frequency response (in the form of a “shepherd’s stand” or mountain like most SB, which require high-order filters and the use of notch chains).

So true

Still loving my 1099, hope you can continue to produce super informative videos.

I’m glad I revisited this video. I forgot how much I learned from this guy a couple years ago. If you are out there, bro, thanks!

That Visa 25mm ring tweeter is a good one. Many years ago I built a two wat with the Skaanings 5” and and a Dyaudio Esotec tweeter. One of the tweeters got wrecked by a hockey stick( don’t ask) and I decided to use the Vifa ring radiator as a drop in. It was cheap and had similar specs. I actually preferred the sound to the Esotec.

You need active electronic crossovers that you can actually regulate continuously until you balance everything out , Rane and dbx work well. I don't waste time and money with passive anymore.

Can diffraction be reduced by A. sticking a sponge material around the speaker on the baffle at say 2" away, using the self stick door draft excluder type that about 1/4" square. B. Routing a dado channel in the baffle around the speaker at say 2" away and gluing in a strip of sound deadener. C. Using a dado channel as at B instead of sound absorbing material, put in a circle of hard wood or plastic that is rounded over with a slight protrusion and polished or natural, like a speed hump for soundwaves. But the height above the baffle may need tuning depending on frequency, irrespective of height it might be worth a try.

Hiquphon OW1 easily. The RS28F is very smooth, but maybe not for older ears. SB29 and XT25,wonderful. I’ve yet to use a SCAN or Seas tweeter that I like.

Transducer Lab N26CS-G

I have a custom cable that goes from speakon to Jack. I want to run this power amp to a load box then using the line out of the load box for entering into a cabinet simulator. May work right? Using just one channel in mono. Guitar guy here...

A guitar is a terrible instrument to demonstrate this. You cannot tune a guitar perfectly. Studio musicians tune their guitar to where on the neck most of the playing will be done (5th or maybe 12th fret)

Its possible the sound may change after its been used for a few months.

Do you know of a source for a very basic learning tutorial for Xsim? I know that is not what you intended on this video. I mean very beginner basic. I wanted to start making my own speakers, but I see now how I can't just use calculators online and expect good results. Thanks.

Also a lot of beginners do not own a router or CNC wood working equipment either!

Nice No sound test.

People forget that a baffle is also reflecting sound back that is reflecting from walls and objects in the room

Thank you for making these great vids, I have found them incredibly inspiring!

Hope you are still around. LOL. So, I guess I didn't get how adjusting the values in a 2nd order xover at 2K in a two-way design has an effect on baffle step loss in the 150-500hz range.

O missed the part for the Audio test. Wanted to hear the clarity. Next time.

A plastic membrane compression driver is not a tweeter. You need at least a titan. It’s easy to determine which type by FR: a plastic has that remarkable falling deep from 8kHz to 15kHz and then a rocket jump to 18-20kHz. Independently of a manufacturer. All you can make with them is to use a sophisticated crossover to make it flat in a range of 3-5kHz up to 20kHz with a 90dB sensitivity. But the next question then is why a h do you use a compression driver for that if you can take a trivial dome tweeter??

Can these drivers be used in a car audio setup (Tymphany NE95W-04) Especially in a hot region like India?

something wrong with the site for downloading program, have a good link?

What degree is the chamfer or does it not make a difference?
