Control Resonant: The Complete Set Speaker and Subwoofer Locations (Full Walkthrough)

The Complete Set is a Control Resonant Side Story in which Dylan searches Manhattan for a vintage SINKKI D50 speaker system. He needs to secure four rogue speakers and the missing subwoofer, deliver the full set of five to the Downtown Auction House, and place each piece on the surface named in the setup note before performing a ritual. Finding the components progresses the Altered-item collection goal, and finishing the quest grants the Bout Guard artifact recipe.

Quick answer: Contain speakers at the construction site, Auction House, coffee shop, and Museum of Curiosities. Obtain the SR keycard from Langston to retrieve the subwoofer in the Oldest House, then position all five items on their assigned Auction House surfaces and respond to the subwoofer’s last question.

How to start The Complete Set

There are several ways to start this quest, but each adds the same entry to Side Stories. The first opportunity is in an apartment at Central’s western edge. Go upstairs to the second floor, enter the first door on your left, and pick up the Pete, Nina and Lester recording by interacting with the corner phone; this launches the mission. You can also start it by nearing the speaker in Central’s small Atlantis coffee shop or the display at the Museum of Curiosities.

You need the Shift ability to reach the Auction House in Downtown; it becomes available in the West Incursion Zone. This section of Downtown remains inaccessible until you have Shift, so unlock it before heading there if necessary.

All four SINKKI D50 speaker locations

All four speakers behave alike: approach and attempt to grab one, and it will zip around the room, dealing sonic damage. Give it a moment to pause, then close in quickly and select the Contain prompt to pick it up. You may recover them in any order, so choose a route that suits your exploration.

Speaker 2 — the construction site (Central)

From the Collector’s Apartment in western Central, head back outdoors. The speaker sits next to the trash bins directly across from the building.

Interact with the speaker to make it flee to the nearby Frontline Construction site, far to the southwest in Central. Follow it; when it pauses, contain it and collect SINKKI D50 Speaker 2.

Speaker 1 — the Auction House (Downtown)

Travel to the Dense Patterning area on the south side of northern Downtown. Clear the Hiss Freighter and its friends on the rooftops to open the door into the Auction House, which is the hub for the rest of the quest.

Head inside and speak to the Auction House Civilian on the balcony. That triggers the speaker to go wild. Chase it around the hall, wait for the pause, then contain SINKKI D50 Speaker 1.

Before you leave, read The SINKKI D50 Speaker Set setup note on the desk and grab the There’s People In There recording by the couch. These populate your log with the surface instructions for the later ritual and point you to Langston and the Auction Buyer’s Apartment.

Speaker 3 — the coffee shop (Central)

In eastern Central, go to the Auction Buyer’s Apartment and enter the open apartment on the third floor to pick up the Exchange Location Note.

Make your way west-southwest to the Atlantis coffee shop. Clear the Hiss outside, look over the Auction Purchase Receipt indoors, and then interact with the speaker on the table.

Chase the speaker out onto the plaza steps, wait for it to stop, and contain SINKKI D50 Speaker 3.

Speaker 4 — the Museum of Curiosities (West Incursion Zone)

Make your way to the Museum of Curiosities, in the southeastern West Incursion Zone. If its entrance is blocked, trace the red trails above to the Hiss nodes powering the barricade, then destroy all three to unlock the door.

Inside, read the note at the front desk, then head to the back and press the red button on the display. The speaker breaks loose and flies around the hall.

Pursue it through the museum, wait for it to stop, and contain SINKKI D50 Speaker 4 to finish the set of four.

How to find the missing subwoofer

The subwoofer is the most difficult item to find: much of the Bureau has lost track of it, and some employees question whether it is real. Ask Frederick Langston, head of the Field Panopticon, about it near the FBC Field Office at the southeastern edge of Central’s exterior. He says items with no paranormal activity were moved to a storage room near Executive Research, then gives you the keycard for the Oldest House Storage room, marked SR.

Go to the Oldest House, take the first elevator up into the building, and then ride the next lift down toward Executive Research.

Exit and turn left, following the corridor to the corner. Use the SR keycard on the door with SR Clearance Level.

Use the subwoofer in the back corner. It bolts into the corridor and brings in a Hiss wave. Take out the enemies, pursue the subwoofer, and contain it to finish collecting the set.

The Auction House ritual: where to place each piece

Back at the Downtown Auction House, start by placing all four speakers and the subwoofer on the leather couch beside the Auction House Civilian. This is the starting position the setup note describes. Then pick up each piece individually and carry it to its matching surface.

Delivering Items — Drop the full set on the leather couch first, the starting position for the ritual. Shown at 12:12 in Game Guides Channel’s video. Image: Remedy Entertainment

Piece	Surface	Location in the hall
Speaker 1	Glass	Glass table downstairs, near the bottom of the stairs
Speaker 2	Stone / rock	Stone slabs on the stage at the back of the main room
Speaker 3	Raw wood	Wooden bench in the opposite upstairs area
Speaker 4	Blue	Blue tarp draped over the edge of that same platform
Subwoofer	Water	The puddle at ground level, by the caution sign near the console

You may place the subwoofer in the water ahead of the speakers. After all five pieces occupy their designated surfaces, placement is complete and you can start the sequence.

Switch off all four speakers in time

At the console, return to the Auction House Civilian and interact. The civilian strikes a pose like the Hiss as the speakers begin blaring. Before the timer expires, sprint to all four speakers and shut them down. For a straightforward path, visit the glass speaker first, the one by the blue tarp next, then the wooden bench, and end at the stone-slab speaker on the stage.

Taking too long causes all four speakers to switch back on, forcing you to redo the entire shutdown route. Keep the subwoofer active until you make the final choice.

The final subwoofer choice and reward

Once the speakers are disabled, go back to the subwoofer and use it. You will hear two voices—the woman’s and the entity inside the Altered item. The choice wheel lets you decide between two outcomes for the civilian; either way, the reward stays the same.

Turn off the subwoofer — This ends the Altered item’s influence and immediately completes the mission, at the cost of the civilian’s life.
Turn the volume up — The woman lives, with the entity taking control of her body. You then receive a Talk to the Civilian objective; finish the quest by speaking with her.

Whichever branch you choose, the completion screen and reward are identical: a recipe for the Bout Guard artifact. It boosts Power recovery by 50% but makes Dylan take 20% more damage. The recipe appearing in your inventory and The Complete Set disappearing from your active Side Stories list show that the quest is complete.

If the final subwoofer prompt does not appear

A bug can prevent the final choice from appearing, leaving the woman to repeat her dialogue whenever you speak to her. Remedy acknowledges that the subwoofer interaction prompt may be missing and intends to address the issue in a future update. No official fix is available at this time, though the following steps have helped some players.

Reload an autosave, then speak with the woman to begin the conversation again.
Fast Travel out of the Auction House, then retrace your route back inside.
Restart the game.

If these attempts fail, leave the quest for now and return after a fix has been released. On completion, you’ll find the Bout Guard recipe in your inventory, and The Complete Set will no longer appear in your active Side Story list, confirming the mission is done.
