The Complete Set is a Control Resonant Side Story where Dylan has to track down four altered SINKKI D50 speakers and a missing subwoofer before performing a ritual at the Auction House. The speakers are scattered across Downtown, Central, and the West Incursion Zone while Langston gives you the SR keycard needed to recover the subwoofer from the Oldest House.
The quest ends with a choice to turn the subwoofer off or turn the volume up. Both choices give the same reward, but they lead to different outcomes for the civilian. There is also currently a known bug that can prevent the final subwoofer prompt from appearing, which Remedy has acknowledged.
The most reliable fix is a full game restart, fast-traveling out and back, then talking to the woman while the subwoofer speech is still playing and standing still until everything finishes.
In this guide, I’ll explain how to actually do this quest and how to pass the possible bugs and glitches.
What You Need:
What Is This Quest
It’s a side objective where you gather a full set of altered speakers (yes, plural) plus a subwoofer and get them properly set up in one specific location. The table below would be a big help:
| Item | Location | What to do |
| Speaker 1 | Auction House, Downtown | Chase and contain it |
| Speaker 2 | Near Collector’s Apartment, Central | Follow it into the construction site |
| Speaker 3 | Atlantis coffee shop, Central | Find the clue in Auction Buyer’s Apartment first |
| Speaker 4 | Museum of Curiosities, West Incursion Zone | Clear the entrance and chase it inside |
| Subwoofer | Oldest House, near Executive Research | Get the SR keycard from Langston first |
You’ll know you’re on the right track when the game starts talking about delivering a complete set to Langston at the Auction House. That’s your end goal.
If you’re new to this version of the Control universe, here’s how Control Resonant connects to the original game and why it’s considered a direct sequel and if you’re wondering what happened to another familiar face, here’s where Ahti appears in Control Resonant and what his strange scene with Dylan means.
How to Start the Complete Set
The quest doesn’t scream at you with a giant map marker the second it becomes available. You’ll pick it up naturally while exploring the areas around the Auction House and nearby zones. Keep an eye (and ear) out for:
- A subwoofer that has strong opinions
- A civilian who is very concerned about what’s coming through the audio equipment
Once you’ve collected the pieces, the game expects you to place them in the correct spots. Placement is pretty intuitive once you’re in the right room, just don’t overthink which speaker goes where. The game will let you know when something is in the right position.
Two Requirements
To do the Complete Set Quest, you need to investigate collector’s house and look for the subwoofer, these two requirements are not that hard. Anyway I’ll try to help you do them easier with the pictures below:
Finding the subwoofer and completing the quest, put everything where they should be:
| Item | Required surface | Actual location |
| Speaker | Glass | Glass surface near the bottom of the stairs |
| Speaker | Stone/rock | Stone slabs on the stage |
| Speaker | Raw wood | Wooden bench upstairs |
| Speaker | Blue | Blue tarp hanging from the upstairs area |
| Subwoofer | Water | Puddle beside the civilians |
If you’re clearing other side tasks before heading back to the Auction House, you may also run into Escort Ranger. Here’s where to take the Rangers in Control Resonant if the objective marker isn’t helping.
The Final Setup
After everything is placed and the speakers are turned off, the sequence with the civilian and the subwoofer begins. This is where most people get stuck.
What should happen:
- Voices play.
- The civilian reacts.
- A prompt appears that lets you make the final choice (turn it up or turn it off).
What actually happens for some players (like me and you):
- The voices play.
- You hear a scream.
- The prompt never shows up.
- You can keep talking to the woman forever like she’s stuck in a customer-service loop.
If you can spam dialogue with her and nothing changes, congratulations, you are officially bugged. The game is waiting for a trigger that never fired.
The Fixes That Actually Worked
Completely restart the game (full quit, not just reload). Fast travel somewhere else (Central works fine). Travel back to the Auction House area. Talk to the woman while the subwoofer is still doing its speech. Stand still and let the entire conversation finish.
Do one or several options of restart, fast travel and talking during the speech. They were the magic sauce for me and it worked for real.
Other Things Worth Trying
Sometimes bugs are persistent as hell. In a situation like this, try these:
- Stand completely still after the voices end. Some players only got the prompt when they stopped moving.
- Reload an autosave from before you placed the speakers on the setup.
- Keep interacting with the woman until the game finally decides to let you target the subwoofer.
- Wait longer than feels reasonable after the scream. The trigger seems slightly mistimed for some people.
If you reload just to see the other choice and then get stuck, you’re more likely to need the full restart plus fast travel method. The game gets salty when you second-guess it.
Extra Tips So You Don’t Rage-Quit
Save before placing the final pieces. Future-you will thank present-you. If the dialogue keeps looping, stop trying to “fix” it in place. Leave the area.
The quest involves a meaningful choice at the end. Don’t stress too hard about which one is correct, the game acknowledges both paths.
Once it finally works, you’ll get the confirmation that the complete set is waiting for Langston. That’s your quest complete moment.
Still Stuck?
You’re not alone. This trigger is clearly a bit fragile. If none of the above works after a couple of clean attempts, report it through the official channels and try reloading a slightly earlier save. Sometimes the game just needs a full mental reset (same as the rest of us after a long session in the Oldest House).
Now, wear your best outfit and go finish that set and try not to think too hard about what those speakers were actually broadcasting. Some mysteries are better left with the volume turned down. You’ve got this.
The Complete Set Reward and Trophy
The reward is the Untapped Bout Guard artifact and the finished artifact increases Power recovery by 50% while increasing damage taken by 20%. Completing The Complete Set also contributes toward Panopticon Intern, which involves containing Altered Items. So, its rewards are worthy just like Patterned Thought which helps you upgrade significantly.
