I own a Crate Flexwave 120h head and have the Full stack CrateFlex 412a 4x12 and CrateFlex 412b matching cabinets. It's a full stack. The only confusing part of using this was how to select the ohms setting on the cabinets...Its either 4 ohms mono or 16 ohms mono but no stereo 4 oms each side. The Flexwave 120h has only one speaker out which is 4-16 ohms automatically adjust to whatever speaker cabinet is used. I use two 4x12 and set them to 16 ohms each and jump the two of them and run the top cab into the head. I believe it's self-adjusting to 8 ohms running two 16-ohm cabinets daisy chained. I'm reading comments and reviews with people posting that these cabs are made of MDF, that's not true at all and I can say I've taken the back off both cabinets to reveal both cabinets are made out of plywood, a very light weight plywood. All sides as well as front and back are made out of plywood. Maybe I got an older set of speaker cabs but mine are both feather light compared to my other 4x12 cabs and both are 100% plywood.The speakers are Crate's specialty 30-watt speakers' model "HM electronics" made by Acoustic Labs. My head and full stack was manufactured 2006 Designed in the USA and made in China. Overall Crate is a recommended product that's been around since the early 80's and their crunch and high gain tone was designed around the Hair Band and Metal era. My favorite guitar tones were from 80's-90's.

Sound
Sound is pure, mids are pronounced and… read more when paired with matching Crate Flexwave 120h sound is perfectly matched.

Features
I have a Crate Flexwave Full Stack. Both A&B flex412 cabs...Both are made of 100% plywood, front, sides, top and bottom and even the back board is made of plywood and not MDF.

Ease of Use
Crate is a really well-known name that gets overlooked...I own the Flexwave combo amp 1x8 and also a Full stack Flexwave 120h and it never dissapoints me using it...

Quality
My two Flexwave cabs are still holding up since 2006 and still going strong after many guitar sessions and volume cranked 3/4 the way from my 120h Crate head still sounds amazing...Actually sounds better after the speakers were broken in.

Value
I still see these cabs for sale cheap, don't hesitate to buy one...Ignore the people that are saying these cabs are made out of MDF and sound bad....Mine are made out of 100% plywood and the speakers are excellent and I believe were custom made by Eminence and rebranded by Crate.

The Wow Factor
Crate is a brand that people tend to overlook until they actually play it. They remind me of an alternative to what some of the plethora of amps are making today...They have a beatiful clean channel, a really mid focused crunch channel (Marshall tone) and a very good High Gain channel (Randall on steroids sounding).The 120h is a do all amp...
