The Yamaha VXC8SW is a purpose-built ceiling subwoofer that enhances the VXS and VXC series systems with powerful, low-end extension while preserving the architectural integrity of the space. This S-model in-ceiling subwoofer is engineered to deliver tight, musical bass and clean integration with full-range speakers, letting you enjoy deeper sound without sacrificing interior design. Perfect for commercial environments, home theaters, or multi-purpose rooms, the VXC8SW sits discreetly in the ceiling and becomes an invisible powerhouse that elevates every listening experience.
Designed to smoothly extend the low frequency range, the VXC8SW handles demanding audio with poise and clarity. Its compact, white enclosure blends with most ceilings, ensuring the speakers remain the focal point of the room rather than the installation hardware. When paired with Yamaha’s VXS and VXC series, this subwoofer provides a cohesive sonic footprint across the entire system, delivering theater-like bass for movies and impactful musical bass for immersive listening experiences. The result is a balanced soundstage that faithfully reproduces bass notes with accuracy and depth, enhancing dialogue, effects, and musical nuance alike.
Beyond raw power, the VXC8SW is engineered for reliability and ease of integration in professional installations. The 8-inch woofer is optimized for ceiling-mounted configurations, offering controlled, well-defined low-frequency output that complements the mid and high frequencies produced by the main speakers. The white finish and flush-mount design minimize visual intrusion, making it ideal for venues with strict aesthetic standards—from corporate lobbies to modern living spaces. This makes the VXC8SW not only a sonic upgrade but also a practical architectural solution for spaces where aesthetics matter as much as audio quality.
- Seamless architectural integration: Flush-mount design and white enclosure let the VXC8SW blend with standard ceilings, minimizing visual intrusion while maximizing bass performance.
- High-fidelity bass extension: Engineered to smooth the low-frequency range when paired with VXS and VXC series speakers, delivering bigger, more true-to-life musical reproduction for music and multi-channel movies.

Works great, do the double drain for best results
My 06 Altima (185k miles) had been burning massive amounts of oil (like 4 quarts every 800 miles) due to a leaking PCV valve hose that took forever for me to narrow down (months). So after getting that under control I figured I needed to decontaminate the poor engine.
When using this I idled my car to operating temp (about 8 minutes). Poured the bottle in, idled it for another 15 minutes. Drained the oil (black and thick). Put the plug back in, poured about 2.5qts of new oil in. Idled it for 10 minutes. Drained that (black but much thinner). Took the old filter off. Let both areas drain for 10 minutes. Put the plug back in, put the new filter on and filled with the 4.6qts of new oil my car calls for. Ran for a few minutes (like 2 with a few revs) and then let sit for 10 mins before checking the level.
When I checked my dipstick it was so clean I thought I had a leak because I couldn't see it on any of the crosshatch. I ended up having to go by touch to get the reading. This stuff is amazing.

Worked for me! Definitely recommend!
Used a whole can in my 2009 Civic 1.8L with 150k miles. I can honestly say, this helped remove a lot of sludge out of the engine. The oil came out with a water-like texture and super dark! Before taking out the oil filter, I added new lower cost oil to the engine and let the engine run for about 5 minutes to get that extra flush! You can definitely see all the extra sludge in the new oil!
Drained and refilled with new oil and filter. The engine definitely sounded quieter and smoother than before!
If you value your car, I would definitely recommend doing this flush on your higher mileage cars every 50k miles or so!
Definitely recommend this LiquiMoly product!

3rd Update! See review... Good stuff and works as advertised...
Update - 3rd oil change/flush. Engine oil draining from engine is waaaay cleaner than my first flush. Probably won't need to do a 4th time for several changes. I added Ceratec at this change and am amazed how much better the engine performs since my initial flush. Less clatter and very smooth idle. (Jeep 4.0 I6)
Update- 2nd change and used the flush again. About 7000 miles from first use. The oil was cleaner and less "gunky" as first time but oil was definitely dirtier than normal. Right away noticed off idle throttle response improved. Then on a drive I take regularly with a mountain pass and long downhill I noticed that even tho the jeep downshifted out of OD it took much less throttle to hold 65 up a long grade. On the downhill normally I would see 50-60 mpg max on the digital readout. This time. It went to 99 which to me indicates more vaccum below the throttle plate. My guess is the rings freed up a bit more than the first flush and highway mileage is up to 23+ where I would get 21 before. Nice!
Used in 2001 Jeep Grand Cherokee. 140k miles and a ticking lifter (common in the 4.0 - 6 cylinder...). Definitely cleaned sludge (oil filter very heavy!) and oil was dark when draining. Idles smoother, oil stays cleaner longer, slight oil pressure increase and runs cooler. The lifter still ticks but probably a cam lobe issue. Will use it after 7500 miles or 1 year. Will report back after next change.

Tips and tricks
I watched several videos by professionals who used this. Follow instructions. Make sure the engine is warm before you put it in. Make sure you have everything you need. The biggest tip I got that was repeatedly emphasized by the pros was to buy a “cheap” oil in addition to the new oil. After you run the flush drain the oil and flush. Put the cheap oil in and “rinse” the inside of the engine with the cheap oil. Then drain again. Replace the oil and filter with your good stuff.
I followed these instructions or suggestions and….
I sat in the truck while the flush was running. It’s a 13 year old truck with 150,000 miles. It was running strong but burning oil and kind of loud. Sounded like it was growling. There were some ticking type noises that made me nervous. As I sat in the truck and let the flush cycle through the engine at idle I could literally hear the flush working. Very slowly it was like someone gave the engine a Xanax and you could hear it getting quieter and calming down.
I drained, rinsed with cheap oil only letting the cheap oil run through at idle for another 15 minutes then drained again. The oil flush was clearly important. It didn’t come out as black as the first drain but it looked like old nasty oil.
The truck is no longer burning oil. My gas mileage has increased significantly and it is running so quiet and smooth it’s unbelievable. I used a little less of the liquid Molly flush than it called for regarding the flush to oil ratio. I didn’t want to do something too intense to the inside of the engine. But the results were remarkable. Just as advertised after following the instructions. I also added the liquid Molly oil additive to the final oil change to ‘lube’ the inside of the engine. I plan to do another flush in about 10,000 miles.
All that to say, yes, you won’t be disappointed as long as you follow instructions and a few tips and tricks. My truck is almost running like a brand new truck and again it’s an old and tired truck. I will use this as part of a high mileage maintenance and perform the flush every 50,000 miles or so. I feel confident it will extend the life of my engine based on the results

Seems to have helped
Bought a used 2020 Jeep Sahara 2 liter turbo charged with 80k miles from a dealership. Dealership had just changed oil the day of purchase. Drove it home 30 miles down interstate and another 20 back roads, it ticked and tapped allot at idle and the dip stick was varnished.
I added the flush, let it idle for 10 minutes and drained it. The new oil from the dealership drained out jet black, no light could pass thru it.
I changed the oil with Walmart oil and a cheap oil filter and let it idle for 5 minutes to clean out all the engine flush, it drained out clean and clear.
I refilled it with Pennzoil Platinum High Mileage oil and a Fram Ultra Synthetic oil filter. It's been a week and the engine is noticeably quieter and smoother since using this product.
If nothing else it cleaned allot of carbon from inside of my engine.
