Connecting ACTIVE speakers with no Sub out to an ACTIVE Subwoofer

[kalelzkryptonite]

Hi All, I had a question regarding sub woofer connections and hoping to get some answers so that I can clarify my understanding.

What I am struggling to understand is how to connect an Active powered Speakers to an Active Subwoofer, in a case where the active speaker doesn't have a sub out. Please note I don't want to use an AMP or a Receiver as I have no space. I need my TV sound to drive the system.

Can I provide the sub woofer with Line level inputs from the TV directly and then have a line level out to my active speakers from subwoofers? Will that setup work?

1. I want to pair the following models if that helps in answering the question -
Active Bluetooth Bookshelf Speakers D300 - Swans Speakers + SB-1000 Pro

The above sub has both line level Inputs and outputs.
So my TV ( LG OLED B8 ) connects to the Subwoofer's Line Level Input
Line level out on subwoofer to (Inputs on Swans bookshelf speakers ).

2. How about if I want to connect a sub with no Outputs like this one?

In this case can i use a Y splitter from TV out to connect to both speakers and my subwoofer inputs?


Hope this is enough information to get some inputs/suggestions, any help is appreciated and apologies if it made no sense

Thanks

Since both are active I would suggest the following checks and (perhaps) solution.

1. Connect the speakers directly to the tv, if it works, ok
2. Connect the sub directly to the tv. Same thing. Configure it well.
3. Get a RCA splitter which makes it able to connect both.

Thanks AJM for the response. I don't have the speakers yet, I wanted to understand first before buying.

I have a 3.5mm out on my TV. So is your proposal will work something like this?

1. Split 3.5 mm into RCA left and Right.
2. RCA Left splits into Left input master speaker and left input subwoofer.
3. RCA right splits into Right input master speaker and right input subwoofer.

Attached a pic for confirmation.


In this case the base frequency will go to both Speakers and the Sub correct?
Any major impact on listening experience?

Thanks again

Yes, that is the idea. I also had some active monitor speakers connected to my TV while living abroad. The thing is that I can not give 100% guarantee soundwise as in if it won't or will add some interference after splitting (never went that far).

In this case in between checks would be welcome. My second TV here has a broken rca output port which I would not like to discover after buying a lot of gear.

You are better off either routing all of this through an AV box/processor or getting a powered sub with outputs for satellites.

Yeah i know that's the best way to go for it, but i just don't have the space on my console at t he moment , hence the alternatives.
