Connecting 6 Ohm Active Universe Subwoofer to 8-16 Ohm Stereo Amplifier: Impedance Safety

Question

Hello, I have an active universe subwoofer that remained after my home cinema. I checked that the speaker has 6 ohm in it. I would like to use it now for a stereo amplifier (8-16ohm), I know how to connect it, I tested it, my question is whether it is safe because the impedance of the speaker is...

As usual, traditionally; no picture ... Eh! This is how it works, for 100% certainty we will ask for a photo.

This is, so to speak, the grommet, the loudspeakers load the amplifier, and through the appropriate sub-dividers it borrows the audio signal. The amplifier will see the impedance of the speakers.

Electrically, the same (as long as A + B is a normal parallel connection), i.e. you can. attention this does not apply to UNITRY inventions, e.g. PW 7010

The instructions were enough, it coincides with the instructions. 2 sets of 16 Ohm in parallel give a net impedance of 8 Ohms. Plug in and check. It should work.

What do you write ... The subwoofer is ACTIVE as you write. It has a built-in amplifier, so you don't care about the speaker impedance inside! You need a fader (if the sub has no high level input). If there is a high-level input, then connect normally.

Gentlemen, thanks for the answers so far, I attach photos, please look and make sure that I can connect this sub with no worries

Thank you very much for your help and support, so tomorrow I will connect the sub to the receiver without any worries :-)

greetings

Hello, one more question

since there is no danger to connect the amplifier to the high-level subwoofer input (input from amplifier), I understand that it is possible to connect a subwoofer to the "B" output - this way you do not do a "pass" through the sub, only reach it with the signal directly from the amp - from the "A" output to directly power the speakers? Later, of course, have "A" + "B" turned on in the amp, I mean the solution as in the attached picture at the link: https://obrazki.elektroda.pl/ 2050288700_1488893507.jpg
Thank you in advance.
greetings

And here is the problem, it is not known whether the amplifier connects in parallel or in series. Usually on the back of the amplifier there is a mention of the minimum impedance for sets A and B, A or B etc. It can be concluded after this whether the combined sets are in series or in parallel. Well, no one knows what amplifier it is.

This is a new basic Yamaha rs 202d ampli ... I think I have to look at it from the back because I don't know what it says ...

sylweksylwina · Answer

By. instructions with sets A and B on, the minimum impedance is 16 Ohm per column. It turns out that they are connected in parallel so everything should work properly when connecting the subwoofer to the outputs of the second set.

Thanks. I found for sure still a photo of the back panel ... I hope. It is the end of my dilemmas Take a look please ...

Hello connected, to output B, plays and murmurs it is ... better ... although all these new wonderful inventions, unfortunately, do not satisfy my preferences. Maybe audiophile will be disgusted but for me he really played WS4421 with altuses 110 ... or maybe I'm sentimental ... anyway this is the sound I am looking for ... and I can't find anything new ...
