THE WONDER CHILD
Rampage—the name itself instills fear. This addition, the Rampage 6, is all about taking it to the next level. In 2016, our first 6.5″ woofer was released, and it has been continuously refined over the years. However, customers were demanding even more.

As a result, we looked into adapting the Rampage 8v2 to be scaled onto a 6.5″ platform. Using the same configuration of soft parts, progressive roll Nomex spiders, and carbon fiber cones, it certainly looked the part.

REAL RAMPAGE
Not just a marketing gimmick or a revision of a previous subwoofer, the Rampage 6 is a true adaptation of the Rampage 8. It even uses the same 2″ copper voice coils with ceramic coating.

The main difference in appearance is the magnet design. While not as wide as the Rampage 8″ (being 0.6″ narrower due to the physical dimensions of the basket), it has grown in depth, making the mounting depth the same as the 8″. The entire motor structure is 1″ taller, so the actual weight of the Rampage 6 is nearly identical to the 8″, offering a similar BL product as well.

The progressive roll, multi-layer spider design is made with efficiency and linearity in mind, while still being stiff enough to keep the moving parts centered. This is also reflected in the respectable resonance frequency.

Nice for the price
Set name: 5.1 Receiver, Set name: 5.1 Receiver
Was extremely easy to set up. The automatic sound balancing works good. Sound quality is good as is the surround sound feature. I personally feels it loses a bit of sound quality when connecting a Bluetooth item like my phone. Otherwise, I am satisfied.

Far superior to price comparable Sony receiver
Set name: 5.1 Receiver
I want to compare this to Sony STRDH590, which I owned before this and is of a comparable price. My Sony stopped receiving signal from its remote control within 2 years. There was no way to control many features due to this. The Yamaha has a wide range of buttons on the front if the remote fails. Now that I have this Yamaha and can compare the sound, this is MUCH better than the Sony. The sound is crisp and clear. This Yamaha receiver has a 5ch stereo expansion setting and the Sony did not even have that. This receiver also has a direct setting that turns off all extra parts of the stereo to attempt to get a clearer signal, including the front panel. The Sony has the nicer input ports (the ones that take the banana plugs) only on the left and right channel where this Yamaha has them for all five channels. The subwoofer output from the Yamaha is considerably better than the Sony and produces a cleaner sound. The Yamaha setup is extremely easy and takes just a few minutes with the included microphone. So far I haven't had too much difficulty with voices being quiet in movies. There are several applicable sound options for how to process movie input. The only downsides to this Yamaha are that it only has 4 HDMI inputs and doesn't support eARC. According to the marking ARC is only on the first HDMI input.

Excellent sound and function
Set name: 5.1 Receiver
We're very pleased with this unit. We use a 3.1 system in our TV area, stereo plus center channel and subwoofer. It's nice that this unit supports that. We get very nice imaging from this, and don't really miss the surround speakers. **We had to replace the old HDMI cables with new ones that could handle the larger bandwidth of 4K. If you're cables are 5-10 years old like ours, newer cables are required to carry a modern video signal. We like the Yamaha sound, and are able to EQ it easily to sound right for the room. I've used several receivers over the years of various brands. Yamaha consistently delivers good sound and reliable product. I've never had a Yamaha product fail and fewer than 15 years. There are other units out there with more gadgets and gizmos, bills and whistles, not to mention smoke and mirrors. We want a good sounding reliable unit that plays nice with all of our AV sources and TVs. If that's what you're looking for, look no further than this unit right here. If you get a good price on this, it's unbeatable. Sony, Onkyo, Denon, Marantz, etc. - they all make good units with signature sounds. If you aren't familiar with them, and If you can't listen to a bunch of stuff, buy this with confidence. Here's an unsolicited recommendation: high quality speakers will do more to improve your listening experience than any receiver. If you're looking for an upgrade, start with your front speakers.

Love my Yamahas
Set name: 5.1 Receiver
RX 385 replaces my much-loved 10 year old RX 375, which I inadvertently fried while experimenting. The 385 has some newer features, including bluetooth. The old model and this both use the handy YPAO function to tune the audio speakers' depth of field to the listening environment. It's a broadcast mic that you just plug into the front of the receiver for a few seconds to determine each speakers' distance from viewer. Kind of a sonic echo measurement of seating to speaker. It's a foolproof, remarkably clever, timesaving gizmo. The YPAO mic is absolutely included with this unit, looks like a little plastic cone. Also important to me, Yamaha has replaced the old spring clips for rear/side speakers, which are now the better screw and cap posts, as they have always been for the two front speakers. I recommend rocketfish HDMI 4k/8k cables to connect this receiver to your tv and to whatever other components you want, such as a bluray. Sound quality is excellent if your speakers are good. (I like KEFs.) Of course you may prefer wireless speakers, but I'm already committed to wired ones. I used rocktfish banana plugs to connect my speaker wires to the RX 385 receiver's speaker posts. Neat and clean. With a choice of 2 front, 2 rear, 1 center speaker, plus one coaxial plug in for a subwoofer, your movies and programs are going to sound far more detailed and staged than you'd get from the tv or a sound bar. It's a more immersive and compelling experience. (I use only 2 fronts and 2 rears and don't feel I'm missing anything.) Yamaha receivers and other components are my favorites: relatively inexpensive, well designed, solidly built, and not fussy to install. If you find yourself in a pickle there are a couple of helpful youtube videos. I find with the RX385 again that Yamaha does not disappoint me.
