logitech z623 how many ohms is a subwoofer ?

[RVXIL]

Need help with the Logitech Z623, which ohm does the subwoofer have 4 or 8 ?

 

[Mosed]

I cannot answer the question, but for me the question would be: For what shall that be relevant?
Perhaps you have a misunderstanding...

The subwoofer uses its own power amplifier.
The impedance of a loudspeaker is relevant, if you connect a passive loudspeaker to an amplifier and you have to set the impedance or want to know if the amplifier is strong enough.
Normally the impedance of an active loudspeaker or subwoofers is not relevant?!

I'm guessing you are trying to find a spare part? - then you should be able to obtain the imformation on the chassis which is already in place. Or i'm completely on se holzweg...

If it is a passive speaker it has normally four to eight Ohm Wave resistance

@mafoe it's not - and most speakers are either 4 or 8 ohms.
In HiFi Forum i found someone who took the Z623 amp to power a selfmade Active Loudspeaker.
He uses 8 Ohm Chassis for the sub and 4 Ohm Chassis for the tweeters.

Hope that helps

To be sure ask Logitech support directly.The ohm value differs within different speakers and subs

I replaced the stock 7" 8 ohm sub that was blown with a Skar EVL 6.5" dual 4 ohm sub wired in series to 8 ohms. It works well in this box size, but the mounting hole is a little big. Repair.

My old subwoofer speaker crashed and I need to find out how many ohms it had, then my multimeter doesn't show.

@mafoe it's not - and most speakers are either 4 or 8 ohms.

I was told in support that the impedance of the subwoofer and satellites is as follows:- Subwoofer: 4 Ohms- Satellites: 8 Ohms ,but the information on the Internet is different.

The support responded like this,but sambuffer is not listed there.

 

[nutrix]

Then I would guess the linked youtube video above might have the info with 8 ohm.

 

[RVXIL]

@nutrix YouTube 6.9ohm and if I put 4 ohms, will everything be okay?

 

[nutrix]

Can you please provide specific details as to why you need this information and for what purpose?

Put 4 ohm on what? On the satellite speaker?

I add that my native subwoofer speaker burned out.

 

[RVXIL]

response from support and the video says that 8 ohms

I'm confused.

You're very spare giving infos. You want to repair the sub and replace the bass chassis, right? Does this really make sense for such a low price device, with costs 120 €? Wouldn't it be more efficient to buy a used sub für 50 € on Kleinanzeigen, or a new set?

I am not familiar with the dimensions of the bass chassis - but here

https://www.pollin.de/sat-tv-audio/lautsprecher/lautsprecher-chassis/

for example, you can always find such parts (for inexpensive devices and repairs at fair market value).

Ich bin nicht mit den Abmessungen des Basschassis vertraut - aber hier zB sind immer wieder solche Teile (für preiswerte Geräte und eine Zeitwertgerechte Reparatur) zu finden

I want to make this Subwoofer.
