Dual Subwoofer

Can you clarify? You are desiring to use Y RCA cables on the Line Out to connect to a power amplifier and powered subwoofer(s) simultaneously?
 
Using Y rca cable from sub out from wiim amp to have dual sub one on each speakers.
 
DOH. I was thinking WiiM Pro. I would confirm with WiiM, but there should be no problem using a Y RCA cable to send the sub signal to a pair of powered subwoofers.
 
I on the Amp pro. I just used a splitter.
Will having 2 sub would yield deeper soundstage? Im more on large scale soundstage over razor sharp imaging. Toe in yield sharper imaging at the expense of smaller soundstage.
 
Splitting a line level signal with a y-cable should be no big deal -- I am doing this with the stereo signal from my Pro Plus to feed a 4-channel amp. Recognize that you won't have independent control of the 2 subs at the source end -- your EQ and room correction will see them as one. Two subs can play havoc with each other and room modes, but with independent tuning that can really even things out. I am using dual subs with my AVR, but it can independently adjust timing, phase, and eq to make them work well together.

Can you use y cable on ultra without having issue?
 
As long as the attached devices don't have wildly mismatched impedances there are zero issues with an RCA splitter.
 
... Two subs can play havoc with each other and room modes, but with independent tuning that can really even things out...
Can you explain more? I thought just using 2 subs and the proper placement would go a long way to defeating room modes, even without independent tuning.

 
Before this goes any further I gotta state that I am not even close to an expert on using multiple subwoofers.
Given that, anyone with a speaker that produces really low frequencies (like a good subwoofer) knows that things can get boomy and bloated or thin and anemic, and sometimes it just sounds crappy. Subwoofers are all about the pressurizing the room (wavelengths that are directly comparable to the dimensions of the room), and a given subwoofer will pressurize the room differently when located in different locations. It's more complicated than with higher frequencies that are more directional. Any of the automated room calibration software spends far more effort on low frequencies than high ones. Most recommend ONLY eq-ing low frequencies where room interactions dominate.

Adding another driver that interacts directly with the room does not automatically make things simpler -- it most likely does the opposite and makes it more complex. Plopping down another sub MIGHT work out great with minimal adjustment. But it might accentuate room nodes and nulls. This is where my useful commentary leaves the chat, as I use the automated room correction system that independently measures and cooperatively adjusts the phase, timing, and eq of both subs, on my AVR to run my dual subs.

I use two Kali WS6.2 subwoofers with Pro Plus and an external DAC. Kali WS6.2 has 80Hz crossover and has high-pass output to feed main speakers. My mains are Kali IN-8. So, I use them effectively as 4-way active speakers.

Can you give us schematic how did you connect your system?
 
I am not good at drawing schematics so I do my best to describe. I assume a subwoofer is an active and has a built-in crossover. Kali WS6.2 can take either balanced XLR/TRS or unbalanced RCA inputs. Outputs are balanced XLR. If you have a pair of passive main speakers, it requires a 2-channel amplifer between subwoofers and main speakers.

Method 1: With an external DAC that has toslink input and XLR output;

WiiM Pro Plus: Toslink output
=> SMSL DO100 Pro: Toslink input from WiiM Pro Plus
=> SMSL DO100 Pro: XLR outputs to Kali WS6.2's

=> Left Kali WS6.2: Left XLR input from SMSL DO100 Pro Left XLR output.
=> Left Kali WS6.2: XLR output to Left Kali IN8 V2
=> Left Kali IN8 V2: XLR input

=> Right Kali WS6.2: Right XLR input from SMSL DO100 Pro Right XLR output.
=> Right Kali WS6.2: XLR output to Right Kali IN8 V2
=> Right Kali IN8 V2: XLR input


Method 2: Without external DAC;

WiiM Pro Plus: RCA outputs

=> Left Kali WS6.2: Left RCA input from WiiM Pro Plus Left RCA
=> Left Kali WS6.2: XLR output to Left Kali IN8 V2
=> Left Kali IN8 V2: XLR input

=> Right Kali WS6.2: Right RCA input from WiiM Pro Plus Right RCA
=> Right Kali WS6.2: XLR output to Right Kali IN8 V2
=> Right Kali IN8 V2: XLR input

Neither am I! But... the thread I linked goes into this in much more detail and might put @Smartplug more at ease. One of the most important issues is subwoofer location & if possible, opposing corners is a great place to start. There's plenty more info on this with a quick Google search!

This is correct!
2 Subs can infact avoid room modes or do lesser the consequences!
I use it exactly because of this.
Has it also an impact on soundstage? Yes, as well, but soundstage is more defined in the frequency above base…

I would disagree with corner placement in general!

Why? It's actually perfect for reducing the influence of room modes.

The only "problem" is additional and uneven bass gain. RC (or manual EQ) easily take care of that!

I cannot believe that. In a corner bass increase due to wall placement is biggest. So modes are going to be bigger too. Same counts for loudspeaker in general - never put them in a corner. Well, then you have additional issues with practically no soundstage etc…

Honestly I was not expecting this question from you…
