Building an M80 Floorstanding Speaker: A Look at What's Inside

It's hard to tell from looking at the outside of a speaker what's going on on the inside. But let's face it: for an audiophile, it's interesting stuff going on in there. That's where a lot of technology and small detail exists that brings you the kind of sound you crave.

As the designer and manufacturer of your speakers, Axiom is able to really customize each part of the loudspeaker, and having our own research facility enables us to dig deep into the engineering side of things to pioneer new designs continuously improve upon the sound. So what exactly is going on inside an M80 Floorstanding Speaker then? Axiom Engineer Andrew Welker walks us through.

Andrew Welker: I thought it would be quite interesting today to show you a view of either a speaker you own, if it happens to be an Axiom Product, or actually what goes into building a speaker box. Obviously most of the time we only see what's going on on the outside of the speaker, not what's inside.

Let's start with the sleeve of the speaker, which is actually one piece that comprises the front, back, and the sides of the speaker cabinet. This is actually CNC machined out of a single, solid complete piece of MDF. This is a piece of our standard finish Boston Cherry vinyl. If I flip this up you can see that the vinyl is already laminated onto the MDF (or Medium Density Fiberboard), which is the wood that provides the strength and the good acoustic properties we want.

In this case the vinyl is actually providing the hinge to allow us to fold the front, back and sides together to make the cabinet. Then all we have to do is add the top and bottom pieces.

You can see we've got a number of different components here. We've got ports, already mounted. There's two on the back of an M80 and one on the front at the bottom.

The crossover network which divides the frequencies between the different drive units - the tweeters, midranges and woofers - is mounted here.

We've got braces, and in the M80 there are four window braces. Those braces are actually locked into these grooves called dados so that when the entire cabinet is glued together and the glue sets, it provides a very very rigid, very solid, vibration-free cabinet.

Another interesting thing that's inside any of our products that have a dedicated midrange are these black boxes: an independent sealed enclosure for each midrange. What's unique about that is . . .

Understanding Subwoofer Controls or What Do All Those Things Do, Anyway?

One look at the back of a subwoofer amplifier and your first thought might very well be “Yikes! What did I sign up for?”

Subwoofer Amplifier Controls


But relax – while each knob, gizmo and switch does have its own job, it’s easy to understand what they do once you hear an expert explain it to you. Listen as Andrew Welker, Axiom Design Engineer, explains the Axiom subwoofer amplifier settings.

Andrew Welker: I’m going to talk a little bit about the controls and the functions that are available on the backs of our subwoofers.

Subwoofer Setup Guide


These days, most of the actual set up and adjustments that you’re going to be doing can be done within the menus of your home theater receiver or processor. But there are some cases, however, where you’ll be using a conventional stereo amplifier to drive the subwoofers, so there are some adjustments that you need to set.

The first adjustment – and the most obvious – is the Volume Level. It’s where you set how loud the subwoofer is going to sound for a given input signal. We recommend that if you’re using a home theater receiver or processor, to set the volume as a starting point at the midway point. From there you can make the more fine adjustments using the set up menu in your receiver.

There’s also the control on the back of the subwoofers that allows you to set the Crossover Frequency. In some cases it’s just a two-position switch that allows you to set 80 or 150 Hertz; and in other cases it’s going to have multiple settings from 40 Hz all the way up to 150 Hz. Again if you’re using a home theater processor, you’re going to set the crossover in the highest frequency setting which is 150 Hz and then you’re actually going to set the crossover point inside the processor or receiver.

From Our Message Boards: What Are Your Demo Discs?

Longime message board member Nickbuol asks: "I started digging through some of my "non-movie" media last night and realized that I have a somewhat large collection of demo discs for my theater. Anything from original DTS DVDs and blu-rays, to ebay compilation DVDs, to massive 50 GB discs put together over at AVS that I've downloaded and burned to blu-ray.

Is anyone else doing the same with demo discs, or do you just pop in your favorite DVD/Blu-Ray/CD and go to a specific track you like?"

"The more I listen to the M22's the more impressed I become. These take more power to drive than my old Paradigm Monitor 7's, but once these are singing they're just wonderful. This is the first speaker with a metal dome tweeter that I've ever enjoyed. Most of them tend to exaggerate the top end or it sounds unnatural to my ears, but these are so sweet and open in the top end, and so detailed.

I was concerned that these might be a little too vocal for my taste, but the mids, while very present, are not overbearing. The bottom end may not be ground shaking, but it is strong, controlled and accurate. No need for a sub when listening to music, which is what I prefer.

This is a very balanced speaker with excellent detail across the spectrum and excellent imaging. I also get the impression what I'm hearing is very close to what is really on the recording - very little coloration. The M22's don't add anything to recorded material - they just reproduce it. Very nice.

My primary reason for trying the M22's was music - especially vinyl. In my living room these are about as perfect as I could want for that purpose. I can't believe these are $519 a pair. The M22's can't be outdone at 3 or even 4 times the cost, in my opinion. Audiophile results at a layman's price. Well done!

I am also very happy with the VP-150 on-wall CC. I haven't had much time to watch movies with the new setup yet, but the few I have tried have sounded excellent with the M22's & VP-150. Much better clarity than my previous setup. I have every intention of ordering a pair of QS8's to complete the system.

Again, well done. And many thanks. Very few people in my area seem to be aware of Axiom, but I will do what I can to remedy that.
