I can confirm that Version 2.1 that I received on July 2017 ( with screen dimmable options and black remote) has working subwoofer output through the coax output in the back.
You can use any 3.5mm to RCA connector (https://www.amazon.com/AmazonBasics-3-5mm-2-Male-Adapter-Cable/dp/B01D5H8JW0/ref=sr_1_1?ie=UTF8&qid=1506722270&sr=8-1&keywords=AmazonBasics+3.5mm+to+2-Male+RCA+Adapter+Cable+-+4+Feet) to connect a sub like like the Jamo J-110 (using it now). Jamo J-110 has line in instead of high level input/output and is working great.

Does it feature any sort of crossover to strip out the bass from the non-sub speakers? That would be ideal for me!

I don't see any. There is options for equalizer, bass boost, and treble. You can Google for the manual just to verify.

It doesn’t, still sends full range to the speakers.

No problem. I couldn't find the answer either so I just went ahead and tried it. Glad it worked out lol.

Rats; that sucks. What's the point of a dedicated subwoofer out then? Only one point of driving full range to speakers - if one doesn't connect the sub!

The obvious explanation is that SMSL decided to save on production costs by not implementing a crossover when the subwoofer-out is in use. One would have hoped they would have used a crossover in the AD18 after the feature was lacking in their Q5 line. Maybe for their next model...

That's a downright flaw in the AD18, everything else being nectar

Is there some sort of passive crossover high pass filter (or pair) I can buy to place between the ad18 and the speakers to prevent the low frequencies from going to the speakers? Been looking but not sure what to buy?

Good point. I don't own the AD18 yet, but headover to AliExpress. I found some crossovers, but a lot of those vendors often blow up specs and even downright lie. Your best bet would be to read reviews (especially negative ones) before you spend.
Even if we did put a high pass crossover in between, we'd still have to shield to prevent interference.
Existing owners, any tips or pointers to @loveknives's suggestion?

So I'm looking at different crossovers and found something like this? https://www.amazon.com/Diamond-Stereo-Passive-Subwoofer-Crossover/dp/B01D1ZAPDC/ref=sr_1_7?ie=UTF8&qid=1512233327&sr=8-7&keywords=passive+crossovers+for+speakers Would this work? Speaker wire in to this and speaker wire out through the front to the regular speakers? Keep sub out through the AD18? It says this: 275 Hz @ 6 dB 8 ohms Hi pass, does this mean that it attenuates signal below 275hz by 6db?

Yeah, these work. They’re usually meant for automotive applications, but nothing says you can’t use them at home. 275hz is a pretty high cutoff though, is there one that crosses at 100hz or below?
other options: PAC BB-2PR Pair of Bass Blocker Designed for 6" Speakers https://www.amazon.com/dp/B009D9IGIM/ref=cm_sw_r_cp_api_MAViAbQSD8350

as a side note.... I do believe people are making this out to be a dealbreaker, when I’m not sure it should be. this unit has an EQ, you can just turn down the bass on the main unit and adjust the subwoofer level until the blending is smooth.

Hi menzinho, not sure how those bass blocker pair link you sent works? Are you saying I need 4 of them? 2 for each speaker? And do I just twist them onto the speaker wire? Also, the link to the ones you sent out block at 300hz? They also look pretty different from the link I sent out (which looks more like the back of a subwoofer and has some capacitators and other wiring on the back, not just a cable like what you sent). What's the difference here? I'm using these basically as a home theater application and I'm definitely hearing distortion in my speakers with LFE/very low hz sounds. And my stereo speakers go down to 40hz, and want to use my subwoofer to help out the speakers to prevent distortion.

Just to clarify the last part: You connected one of the two RCA males to the LINE IN of your Jamo subwoofer? (or connected both RCA males?). According to the AD18 manual, they say that only the red RCA should be used for the subwoofer. Also the 3.5mm is connected to the subwoofer output of the AD18, correct? Thank you for clarifying this! I want to buy this one: Polk Audio PSW10 10-Inch Powered Subwoofer (Single, Black). This one has also a LINE IN input. so I should be OK, right?

The 3.5mm to RCA cables goes from the subwoofer out on the back of the AD18 to the two RCA male line in inputs on the subwoofer. I connected both the red and white and I haven' had any issues.
Also, i just unplugged the white RCA on the back of the subwoofer. It seems that you are right, it works with only the red line in connected and you don't need the white one plugged in. Thanks for pointing that out!

Thanks a lot for your help! Finally I got some clear idea of what to do! Next, buying a nice (but cheap) sub-woofer - the Polk Audio one..... Let's see how it works. More to come!

Im not trying to force my opinions on you or anything, but perhaps you should give this a read: https://www.reddit.com/r/BudgetAudiophile/comments/7q59mo/public_service_announcement_stop_asking_if_you/
