But the first 30 minutes of the film depicts one of his pre-crash missions as a crewmember in a B-24 bomber. When the film was released in 2014 this opening sequence became prime demo fodder at home theater shows everywhere. It’s alive with the roar of four noisy aircraft engines, wind from the open bomb bay doors as the crew attempts to close them, machine gun fire, exploding anti-aircraft flak, and a near tragic crash landing. While in some respects the KEF, in my room, didn’t attempt to deliver the sort of ear-searing experience the above description might suggest. It was instead totally believable—realistic without pushing over-the-top simply for effect. Never having been in the same situation as the bomber crew, I can’t say for certain exactly what real machine guns and flak explosions sound like. But I was impressed enough by the KEF’s crisp, bottom-end clarity and startling punch to convince me that I’d rather not volunteer as a crew member on a B-24 bomber to experience the real thing!

Of all the films in my collection, however, Blade Runner 2049 offers possibly the most challenging bottom end. While the KEF can’t quite match the sheer bass weight at high levels of the two ported, spatially displaced subwoofers that usually handle the deepest bass in my room, it came remarkably close at roughly one-eighth the total size. The KEF also surprised me in how it revealed to me (for the first time) some very deep and extremely low bass in both the abandoned factory scenes (as officer K/Joe searches for clues to his past) and, later, a sequence in a similarly abandoned Las Vegas.

The towers and center give you the option of running in sealed or ported mode, the later having multiple variations affording you the ability to tune them for whatever works in your situation. The center has 2 ports, so 3 possible configurations; sealed, 1 port open or 2 ports open. The towers have 3 ports, giving you 4 potential variations. Arendal includes very dense plugs for each of the ports, all of which fire out the back of the enclosure. That goes for the 2V subwoofer as well, its port is also on the back of the enclosure. If you’re at all concerned about “chuffing” – port noise – don’t be oriented that way, it’s all but guaranteed you would never hear it even if there was any.

The binding posts on all the speakers are the same, perhaps the best word to describe them is beefy. They’re made from polished, CNC machined copper which is then plated with highly-conductive, and corrosion resistant, Rhodium. However you want to hook them up you can; banana, spade or pin type connectors, as well as bare wire. There are 2 sets of posts on each speaker allowing you to bi-amp them. If you choose not to go that route Arendal supplies stout Rhodium jumpers to bridge the posts.
