What kind of cables do theses work with? Can I use a quarter inch rca? Does mass drop sell the appropriate cables?

JadMaktabiwhat is you intended source, just your PC and some external device?
The LSR30X has an XLR and TS input for each speaker.
https://en.wikipedia.org/wiki/XLR_connector https://en.wikipedia.org/wiki/Phone_connector_(audio)
Massdrop provides an 3.5mm to TS cable so they can be plugged into anything with a 3.5mm headphone jack, like you PC. https://www.amazon.com/Hosa-CMP-159-Stereo-Breakout-Cable/dp/B005HGM1D6/ref=sr_1_7?s=electronics&ie=UTF8&qid=1519093767&sr=1-7&keywords=3.5mm+to+TRS
If you have a better source like an external DAC with RCA outs that you can use a RCA to 1/4" cable like the one I have: https://www.amazon.com/gp/product/B00K39U1NE/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1
or use an adapter like this to go run to RCA cables to the LSR30X: https://www.amazon.com/DCFun-6-35mm-Female-Adapter-3-Pack/dp/B06XSC7XRJ/ref=sr_1_23?s=musical-instruments&ie=UTF8&qid=1519094326&sr=1-23&keywords=trs+to+rca
You can do the same with the XLR inputs: 3.5mm to XLR RCA to XLR XLR to XLR

RojasTKDAre you sure massdrop provides a 3.5mm to TRS cable. I just received mines today and I did not get the cable.

Quake1028I suppose so, though I'd leave the XLR inputs for In case I ever went balanced.

JadMaktabiOften shipped Separately. Should arrive soon.
In the past they have been backed ordered and it took a bit longer to Receive.

RojasTKDThe 1/4" TRS port is balanced. Both the XLR and TRS inputs are balanced on this speaker (3 connector). I am going to guess that the 3 wires from each input are on the same signal trace internally. Just clarifying in case anyone is confused on this. The cord that Monoprice sends is 3.5mm stereo to left/right TS 1/4", which obviously works, but it is technically a balanced TRS port on the speaker side.
Balanced works just fine if you discard one of the live wires (live wire #2 is the exact same signal as live wire #1, inverted), it's just more susceptible to hum and interference.

bdleslieYes, I know. So it really doesn't make much difference, still if I get a sourde with balanced outputs I'd just rather connect the XLR outputs to the speakers XLR inputs. It's the OCD in me, can't help it.

I think we're on the same page on this, but you wrote " Massdrop provides an 3.5mm to TRS cable ", but it's 3.5mm to left & right TS (as the link you used https://www.amazon.com/Hosa-CMP-159-Stereo-Breakout-Cable/dp/B005HGM1D6/ref=sr_1_7?s=electronics&ie=UTF8&qid=1519093767&sr=1-7&keywords=3.5mm+to+TRS confirms).
Sorry to be fussy about this, but I think you're trying to provide the definitive answer on what is a legitimately confusing topic. If you look at this picture from Wikipedia, the top plug is TRS (tip-ring-sleeve) and the bottom one is TS (tip-sleeve): https://upload.wikimedia.org/wikipedia/commons/thumb/9/93/Jack_plug.png/330px-Jack_plug.png;
TRS provides 3 signal paths, which is why it's functionally the same as XLR. I agree that XLR is superior to TRS if you have the choice, mainly because it's impossible to screw up; we've all had the experience of headphones not quite being plugged all the way in. TRS and XLR balanced connections have 2 live wires, with live wire #2 being inverted. At the receiving side, live wire #2 is inverted again and live wires #1 & #2[inverted] are summed, which should cancel out most distortion such as 60 Hz hum. If live wire #2 is not connected in the first place, it doesn't matter as you are summing live wire #1 with null.

bdleslieYeah the provided cable is 3.5mm to TS (as in the link). Ill edit that as to not add confusion.
