Do you want more excursion, more thumping power, and to shake everyone's mirrors around you?

DS18 has the perfect subwoofer to satisfy all your bass head needs in the newly designed for the ZXI8.4D high excursion subwoofer. This monster sub packs a 2 inch coil made to withstand high amounts of power with the utmost efficiency while producing thunderous distortion free bass.

This sub has a low FS so it can be used in large boxes with lower than normal tuning. Not only will this subwoofer slay the lows, it is versatile enough to also play higher frequencies in the bass zone of sub frequencies.

The ZXI subline is a great high excursion line of subwoofers that both handle great power and give you smooth clean bass while playing ultra low frequencies. These subs work great in both sealed and ported boxes giving you many options for placement in any vehicle.

This 8 inch model comes dual 4 ohm and comes with a 2 inch voice coil that handles 600w RMS and 1200w max power.

The large foam surround and pressed paper cone works greatly together to deliver smooth crisp bass that can be heard strongly throughout the vehicle giving you an amazing bass experience.

Highlights 

  • Large foam surround giving great high xmax and bass precision while keeping great cone control when the subwoofer is close to maximum power.
  • Great power handling of 600w RMS and 1200w max through a high strength 2 inch CCAW aluminum voice coil.

Worth it!
Size: Queen(Pack of 2)
These pillows are amazing and very soft and comfortable. They came nicely packaged and I let them sit out for just a few hours before using them and that was plenty of time! They come with the cooling cover and fit a standard queen sized pillowcase. The material expands well and does not have any weird smells. 10/10 well worth the price.

Miracle pillow
Size: Standard(Pack of 2)
Best pillow I’ve ever had. I have been using this since December 2024 and it still hasn’t gotten flat. It is amazingly comfortable and solves all my neck issues for a side sleeper. My head never gets hot either. I’ve recommended this to my friends and they’ve had success with it as well.

Really wanted to love these
Size: Queen(Pack of 2)
I really wanted to love these but they gave me a stiff neck. I haven't slept with a pillow since buying these. They are firm except where you lay your head. It just deflates there. I expected it to sink in to match the curve of my neck but it was more than I could handle. My head ended up in a valley between the two ends of the pillow. The price was good, zipper worked fine, it looks as advertised and the pillows are good quality. The cooling part works, its just not what I needed.

best pillow I have ever bought.
Size: Queen(Pack of 2)
most comfortable pillow I have ever bought. It seems very well put together so I believe that it will last a long time. Very happy with the purchase. I do think the weight of the pillow will surprise many people because while it is quite heavy, it is very firm and extremely comfortable. Great value.

I paid for the product and it’s GOOD 👍🏽
Size: Queen(Pack of 2), Size: Queen(Pack of 2)
Honest review to help your decision. These are a bargain at two for one. I paid almost $30 for one at a local retailer and it’s already flattened after 7 months. This product arrives vacuum sealed with the cooling pillow covers separately (separate so you can wash before using). They are loaded with memory foam which I found pleasing. I chose to leave all of the foam in because I’m sure it’ll flatten sometime in the future. I’ve been using these for TWO MONTHS now and they have not flattened. Easy to mold and fluff, soft and they are added support for my back up pillows. I cannot attest to any type of pain relief because I have not experienced that with these personally. I do feel my sleep is better so my tension headaches have lessened. The cooling hex layer is on the cover NOT the actual pillows. I’m sure everyone knows that memory foam gets really hot 🥵 but the cooling covers on these help minimize that. It actually feels cool to the touch like a gel product. I find the quality to be exceptional. All in all, give it a shot.
