The PRO-CF6.4SL is a water-resistant Pro Audio loudspeaker with amazing highs and comparable low mid-bass frequency responses. This speakers versatility allows it to hit frequencies as high as 12.5KHz and as low as 80 Hz providing an extreme full range of frequencies that all listeners will notice and enjoy!

The PRO-CF6.4SL was designed to deliver LOUD audio with striking clarity and remain durable in the worst of the elements.  DS18’s current waterproof carbon fiber cone design and super strong rubber surrounds protect these speakers from damage sustained by use in harsh environments. This also helps increase the sensitivity level on these speakers, so they play LOUD and clear on every use.

Although the speakers components are waterproof, the speaker itself is only water resistant so use in rough conditions should be avoided as much as possible.

The size reduction on this speaker also gives it high levels of functionality in almost any application imaginable! Easy-to-use push terminals help protect and secure wires.

The PRO-CF6.4SL handles great power; rated at 250 watts RMS and 500 watts max, you know this powerhouse of a speaker can get loud and clear!

Rottweiler approved
Color: Purple
My Rottweiler puppies love these bones. I feel good about letting them play with these and not worry they will break or that they can choke because they are durable and a good size and weight. I like the variety and can put peanut butter on the crevices if I want to give as a treat. Worth the money!

Perfect for the aggressive chewer
Color: Purple
I purchased these because I have a 1-year-old black lab redbone coonhound mix who destroys every toy and Bone. I have gotten him in a short amount of time... These things have outstanded this little guy and he is still enjoying them! Keeps him occupied and satisfies his chewing for hours! And he leaves my shoes alone haha

Best for all chewers!
Color: Purple, Color: Purple
I purchased in February and waited until ive had them long enough to make a justified review. I have a very VERY aggressive chewer. He destroys every toy he gets within minutes or a hour. We didnt expect much out of these but why not. Let me tell you... they only have small teeth dents. No cracks, no breaks, no chunks missing, none in the trash, no bleeding gums... nothing. My chewer loves them. First day he just stared at them like they were alien objects but after we played fetch a few times it was on!! Now all three dogs chewer on them. I would say im purchasing again but I dont know when that will be lol I highly recommend to anyone!! Photo is taken today 6/4/26

My pit bull loves them.
Color: Purple
I picked up the Frienhund Tough Dog Toys 3-pack for my large, heavy chewer, and overall I’m pretty impressed. Right out of the box, the toys feel solid and well-made—definitely more durable than your average chew toy. My dog usually destroys new toys within a day or two, but these have held up significantly longer, which is a big win. They also do a great job of keeping him occupied. The shapes and textures seem to keep his interest, and I’ve noticed less destructive chewing on furniture since introducing these. That alone makes them worth it. The only reason I’m giving 4 instead of 5 stars is that while they’re very tough, they’re not completely “indestructible” (despite the claim). After a couple of weeks of heavy use, there are some visible wear marks. Still, compared to most other toys we’ve tried, these last much longer. Overall, a great option for medium to large dogs that are aggressive chewers—durable, engaging, and a solid value for a 3-pack.
