With its 600 watts of power, the active 2 x 10” woofer in a bass reflex cabinet generates impressive bass reproduction, powerful kick and surprising low end. Thanks to its stereo preamp and corresponding outputs, the subwoofer can be used in a whole host of applications. The two mid/high outputs and the adjustable frequency separation in the subwoofer mean that a 2.1 system, for example, can be created with ease, even with active mid/high units that do not have their own filtering. The extremely modest dimensions and flexible setup options, as well as a weight of just under 27.2 kg, are not only advantageous when it comes to transport and handling, but are also ideal for applications that require a small installation area.

Excellent set of leveling blocks
Size: 8.5" x 8.5", Color: Yellow
These leveling blocks work very well for our Airstream interstate 19. They pack very compactly and seem to stay in place when we are upon them. I would recommend they be purchased if you need a set of leveling box

Leveling blocks
Size: 8.5" x 8.5", Color: Yellow
I used these on my first RV camping trip. I was on a not very level site and these worked well to level my camper. They worked so well I ordered another set. The handle is great at keeping the blocks together.

Very happy.
Size: 8.5" x 8.5", Color: Yellow
Bought these at the start of our camping season. I really prefer these to the ones you drive up on that are like a ramp. Besides leaving out under your wheels they can be used for your stabilizer feet as well or your hitch. Quality is great I have not had one crack, I was worried these would be too big to pull my tires over easily but that wasn’t a problem at all. The size allows you to group them together like legos to do what you need to get level. They come in a bundle with a handle that secures them all together in a nice lightweight block that’s easy to store. I actually bought a second set for my fifth wheel after buying the first set. I got them both on sale and am very very happy with them.

Great alternative to wood blocks
Size: 17" x 8.5", Color: Gray, Size: 17" x 8.5", Color: Gray
So I’ve used wood over the years to level out my Class A RV’s and even with the wood sealed, there is always one side that takes a beating. I figured I would try these Camco rectangular leveling blocks and was very surprised at their strength. I’ve only used them twice, but both times the RV rolled right up with no issues. The RV sitting on those blocks in the picture is a 40’ Tiffin diesel pusher. My only issue is the dual wheel base for this big RV, is too wide to use the blocks perpendicular to the wheels, so I had to use 3 blocks parallel (see pics) for each wheel, which required me to purchase two sets. Most sites I setup up at fairly level, but this just provides that little extra height if needed.
