PL In-Wall II

August 2016

Platinum In-Wall II Sets Category Benchmark

"Impeccable sound quality" and "impeccable build quality". Just a couple of brief comments made by Robert Archer of CE Pro made when he reviewed the new Platinum In-Wall II speakers. More great quotes from the review are below: 

"...I was immediately impressed with how big the speakers' soundstage was and how airy the lively Emmanuel steel-string acoustic guitar playing resonated within that soundstage."

"The PL In-Wall IIs were producing a deeper image, more detail and tighter mid-bass than my speakers, which I feel are a great sounding speaker too."

"The speakers were able to provide pinpoint imaging on this track..."

"I loved how smooth and punchy my Train downloads sounded through the speakers."

"...the speakers are well engineered to produce a very involving listening experience from an in-wall mounting position."

"I found the speaker to deliver Monitor's design goal, which is to offer a speaker that matches the sonic capabilities of its in-room products."

"Monitor has created a speaker that arguably sets new performance standards in the architectural speaker category."
