Montana EPS2 Floor-standing Speakers

Introduction

Montana Loudspeakers, marketed by PBN Audio, is a company whose products I have been very interested in for a long, long time. I have seen them at numerous hi-fi shows, and since I have two massive 1,200 watt monoblock power amplifiers that I like to pair with massive speakers once in awhile, I have been attracted to the Montana's, partly because the line includes some really big models. But more importantly, they have always impressed me with the sound quality at shows - which is not easy to do because the rooms are less than ideal - and they are incredibly beautiful.

For this review, really there was no way I could get their top of the line model, the WAS, because each one weighs almost 400 pounds. It was just not feasible.

So, in corresponding with Peter Noerbaek, president of PBN Audio, we decided that the mid-level EPS2 would be most appropriate for a first look at the Montana line. Also, the EPS2 is a new update of the EPS.

And so, they arrived.

The Montana EPS2's came to the lab in two large boxes, and I mean large. As we grunted and groaned to move them into room and position them, I was glad only to have to deal with 135 pound enclosures.

The review units had Rosewood veneer, and the construction was superb. Notice in the photo below how the edges are flawless. Sharp metal spiked feet attach to horizontal metal strips for decoupling the floor.

Drivers include a 1" fabric dome tweeter, two 4" midrange drivers, and two 9" woofers, mounted in a WMTMW arrangement. The woofers and midrange drivers have their own internal enclosures to keep their air pressure changes from affecting the other drivers. The woofers are slot-loaded, with the slot near the bottom of the enclosure.

The tweeter has a felt ring surrounding it, to absorb sound that would otherwise be reflected from the front of the enclosure and cause diffraction. The second photo shows a close-up where you can see the weave of the fabric dome.

On the rear of the enclosure are two pairs of heavy binding posts. The speakers are intended to be bi-wired, so no bus bar strips (for connecting the tweeter posts to the woofer posts) are included. I made some from solid core conductors and put them in. The right side posts are the +.
