Broadband DSP Pre-Release

The introduction of the LFR1100 Omnidirectional Speaker brought about a lot of questions about using a Broadband Digital Signal Processor (DSP) between your pre-amp and your main amp in other speaker models for the purpose of smoothing out small anomalies in the amplitude response. These are referred to as ‘High Q’ corrections to the response curves.

In response to all these inquiries we have created a DSP component that is able to do this High Q correction to the M80v3, VP180v3, VP160v3, and recently announced M100. Since the correction applied from the DSP is concentrated completely in the High Q group we would recommend this product for the discerning audiophile only as the audibility of this correction will be quite subtle.

The cost of the DSP box will be $950 for your two main speakers and $1,260 if you wish to add another DSP in the box for your VP180 or VP160. We will be doing a pre-release promotional price of $690 and $890 respectively from now until the end of July.

M100 Update . . .

And in other news, the new M100 Floorstanding Speaker production is well under way. We're currently awaiting our final woofer build and the printed circuit boards in order to commence production.

The whole team at Axiom is really excited to launch this new speaker!

Video: The Family of Curves

One thing you may have wondered about Axiom's research is what is actually being researched from day to day. Ian Colquhoun and Andrew Welker explain the basis of that research and what they use the anechoic chamber for on a daily basis in the following video, the family of curves.

Ian Colquhoun: Today we want to talk about the 'family of curves', a topic we feel is not discussed often enough. It’s a topic which is extremely important to the sound of a loudspeaker – it is about what you're actually going to hear in a room and how we determine that. As for why it’s not talked about enough, I think there are two reasons:

  1. There's nothing visual about it. You can't look at a product and say "Oh, this is going to have a particular family of curves" just by what the drivers look like, the cabinet looks like, or the components on a crossover look like. None of these things really tell you much of anything about the family of curves, so we tend to gravitate and talk about things that you can see. While that's sensible on one hand, it doesn't really get into the meat-and-potatoes about what makes a good-sounding loudspeaker vs a not-so-good sounding loudspeaker.
  2. The other reason it's not talked about that much is that a family of curves is not an easy thing to measure. There are a lot of curves involved, and you really have to have an anechoic chamber in order to take all of these curves. So it's probably not talked about in a lot of cases because it's probably not measured.
Even just looking at a simple loudspeaker - say a 2-way bookshelf speaker - you're looking at over 150 curves in order to create the entire family of curves that you need to work with and manipulate in order to create what's going to be the end product. You've got the curves of all the individual drivers, and then you've got the curves of the combined end product, and that's going to give you +150 curves. Realistically, in the process of the loudspeaker design, you're going to be doing those over and over again (at least a certain number of them.) You can really end up in a design with over 1,000 curves before you're done. And that's for a simple bookshelf speaker! If you get into a multi-driver tower, you can start multiplying that number by two, three - even four times. So it's not a particularly easy thing to do and you need the proper tools to do it.

And then once it's all done, you still have to interpret what these curves mean. They don't have what you would call a 'normal' sort of visual. If you think about on-axis or a listening window curve, we're used to just seeing something that's reasonably linear across the bandwidth, then that represents a good frequency response. But there's quite a bit more to it. I'm going to turn it over to Andrew now to explain a little bit more about the family of amplitude response curves.

The Spencer's System sits deceptively silently . . . but when they fire that subwoofer up, watch out!

"As promised here are my comments regarding my new amp.

"As a totally blind person all things audio are very important to me. I have an excellent AV Receiver, which for the most part, conveys both music and movie sound tracks well enough. However, I always felt that there was a bit of something that I was just not getting. Within minutes of connecting my ADA 1500 7 channel Amp I found myself smiling as I was hearing all of those dynamics which I previously felt had to be there. I do not know enough superlatives to fully describe the "it", but thanks to Axiom I am now hearing and enjoying "it".

I have 2 EP 500 subs and Qs 8s, which hit homeruns, but this amp. Not only is another homerun, but it left the stadium as well.

When my wife arrived home shortly after I added the amp to my system I put some music on. She exclaimed "what did you do? It sounds out of this world!"

I told her.

If you want the ultimate then I strongly submit that you need to look no further. Axiom rocks!
