BG 20 full-range speaker with tweeter dome VS BG20 NO tweeter dome / DIY speaker build

BG 20 full-range speaker with tweeter dome VS BG20 NO tweeter dome / DIY speaker build.
hello friends!
I'm glad to see you on my KZbin channel.
Today we will conduct an interesting experiment with the BG20 speaker from Visaton.
This full-range speaker with tweeter dome.
for the experiment, I will cut off the additional dome from the speaker.
we will listen to the difference in sound and see the frequency response of this speakers.
here are both frequency response graphs. in the following videos I will try to remove this hump using a notch filter.
see you in new videos.

I'm glad to see you back with a new video. Sounds good 😊.

This is one of the best videos I've seen measuring a drivers frequency response, thank you!

[@goodsound202]

Thank you for watching

[@crtgamer2355]

This is tough to decide...in some passages. it sounds better with the dome tweeter, but imo, most of the time it sounds better without the dome tweeter, this is very interesting results indeed. I thought cutting the tweeter would ruin the speaker, now I changed my mind.

[@writenamehere0000]

Sounds better without tweeter

[@SheikhN-bible-syndrome]

How interesting

[@mariancol2428]

Very good test, it demonstrates how much the orientation of the speakers and implicitly the reflections in the room matter if listening at a distance. Can you tell me what program you used for the tests?

👍🏼👍🏼👍🏼Verygood video.both speakers are fantastic sound quality .difference between both speakers liike 19/20...without whizzer is little first response.both are approximately same to me.but solid wood like pine..teakwood cabinet is better than mdf.for fullrange speakers.👍🏼👍🏼

I'm glad you liked it

[@bartrainer3916]

I see you have a lot of projects ;) I have a question, pleased if you're willing to give me your opinion, please. I own a pair of Audio Nirvana Super 8" coaxial drivers in an +/-90 cubic liter reflex boxes. In your opinion are these Visaton at the level of my drivers if they are mounted in a proper designed cabinet? Regards from Chile.

[@wodzimierzwohn114]

Hello, I am wondering what was the conditions speaker worked? Was it closed cabinet (if yes how many liters) or bass reflex? PLEASE REPLY :)

[@kimvengnielsen7887]

It should be With/ without whizzer cone correct?

[@todokalorr2252]

IS IT CLOSED OR BASSREFLEX AND HOW MANY LITERS IS THE BOX PLEASE! IS THERE A VIDEO ABOUT THE REMOVING OF THE SMALL CONE? THANKS!

[@goodsound202]

housing acoustics solo100 from Visaton. there is no video of removing the cone. simply carefully cut with tweezers or small scissors. I didn’t manage to remove the cone by heating, good glue))

[@snoopyboobs]

strangely sounds like more treble without the whizzer cone.

[@crtgamer2355]

I think I have come to a conclusion finally. Without the dome tweeter the hi hat sounds like white noise and with it sounds more natural.

Hi try adding an aluminium sewing thimble in the centre of the dust cover, please see my video fantastic diy tweeter speakers.

[@goodsound202]

Hi. where can i find your video?

[@steveshore4911]

@@goodsound202 hi sorry youtube have taken down my channel because of copyright issues, but if you put an aluminium sewing thimble in the centre of the speaker it extends the frequency range, and sounds brilliant. Regards

@@steveshore4911 Hello! I'm interested in your method, but I don't understand it! Do you still have the footage available? You can't send it any other way, isn't it possible on watsapp? With that sewing thimble, I think the sizes actually matter, I think there is an ideal size, right?

@@ioanzaman9225 Hi please type. Fantastic diy speakers by adding a simple thimble. Simply glue it to the centre of the dust cover and enjoy, midrange so clean and clear, I find a large one the best sounding. Regards

[@armandocamorra2488]

Con los auriculares puestos y sin mirar la imagen para no saber cuándo cambia . No encuentro diferencia.

[@goodsound202]

los agudos son ligeramente diferentes cuando van al cono. pero no con mucha fuerza.

[@crtgamer2355]

There is a huge difference.

Bg20?

[@martina5434]

All my BG20 (8) are without dome

Pentaton BB?❤

​@@nerdfpv No , my own projekt . Main Speakers are two B200 one in the front (way quiter) and one in the back as close as possible together in a speciel horn whith ventilation to the top and to the bottom . The resistor of the front speaker allowes me to bring in a capacitor in paralell for high boost . I use two BG 20 for the higher sub open (no box). And one 18 inch for the low end open (no box). One BG 20 is on the top of the little horn the other below . The 18inch is near the floor . Totaly hight is ca. 2m . 5 speakers per channel . The B200 have a 3.5 Watt per channel tube amp and this is brutal loud (whith pre amp) . The subs got two subamps . One for all the BG 20s and one for the two 18inch speakers . Whith this speaker system you hear every room , its like beeing the secret service . You need the wall in the back to reflect the sound and i placed various steel pannels in the room to reflect the highs . The room is not my enemy , its my friend , i use it to make the sound realistic and great . The 8inch speakers gives the original size to the instruments and everything . In this constelation the room makes the sound way louder . I hate it to kill sound .

@@martina5434 Das klingt nach einem Hammer Concept👌 den Ansatz den Raum geziehlt zu nutzen anstatt ihn abzutöten finde ich auch besser als andersherum. Kann man die Teile Mal sehen?

[@martina5434]

@@nerdfpv Mein schlechtes Englisch hat mich wohl als Deutschen entlarvt . Und nö , hab eh schon zuviel verraten . Aber die sìnd zur Zeit auch gar nicht aufgebaut . Hab noch was anderes entwickelt , das steht gerade hier . Das ist für mich der Königsweg weil es mit nur einem Breitbänder pro Seite auskommt . Ich würde sehr gerne verraten wie das funktioniert aber wenn ich das vielleicht doch mal verkaufen möchte dann sollte ich mich bedeckt halten . Nur soviel , es ist eine frontloaded Hornform die keinerlei horntypische Verfärbungen erzeugt und den Schall innerhalb des Horns so reflektiert daß sich aus der Summe der Reflektionen ein exakt dreidimensionaler Raum ergibt an dessen Wurzel sich der Lautsprecher befindet . Quasi die Simulation einer lauten Punktquelle bei der die Luft nach dem van Huygens Prinzip ebenfalls in der Form angeregt wird daß sie den Schall in alle Richtungen reflektiert . Im zeitlichen Verlauf ausgehend von der Schallquelle . Also sehr realistisch und nicht einfach nur nach vorne weg wie herkömmlich . Vorne wie hinten befindet sich das gleiche Horn . Das bewirkt daß der rückwärtige Schall komplett nach hinten abgeführt wird und auch nicht das kleinste Bißchen den Weg zurück nach vorne , wie bei einer Box , findet . Eine Dämmung ist also nicht nötig . Es ist wirklich ein Königsweg der den erzeugten Schall mit viel Liebe leben läßt und voller Überaschungen und Wunder die man gar nicht glauben mag steckt . Ich möchte es später , wenn ich wieder Zeit habe , mit dem B200 (hab noch welche) verwirklichen . Zur Zeit habe ich eine kleinere Version mit einem kupferfarbenen Alpair 6 (ca 6cm Membran) . Einziger Wermutstropfen : Man benötigt ein DSP oder Equalizer . Mal sehen wie das dann mit dem B200 und der größeren Variante ist . Möglicherweise geht das auch ohne DSP .

[@gamiwv]

I don't believe at all at this VERY CLOSE mesurment. I like a mesurment at let say 2~2,5 m . That is more realistic. No one is listening music at 10~30cm, I believe

[@goodsound202]

at a great distance, the room has a great influence. each room makes its own changes

[@gamiwv]

@@goodsound202 I know that but it is more realistic

[@kampfmeersau]

@@gamiwv more realistic for this specific room, yes. But less comparable to other rooms. That’s why measurements are always taken so close to the speaker.
