I spent some time today researching ABX methods for this listening session as I wanted to quantify the subjective differences as much as possible between these two subs. In order to derive statistically significant results that chess would be happy with \:\) , I'd have to do the following for music and then again for movies:

1. Compare with at least four different independent variables (ie. 4 subs or 3 subs and no sub),
2. Conduct at least 4 listening sessions with 4 people in each,
3. Conduct at least 16 trials per two-pair combination of independent variables for a total of 6 combinations and 96 trials per listening session. This is a total of 384 trials,
4. Each of the 96 trials per session would last at least one minute for a total of at least 96 minutes. More realistically, two to two-and-a-half hours would be required per session,
5. The participants would have to comprehend detailed instructions prior to their arrival,
6. The participants would have to complete four forms during each session,
7. The environment would have to be low stress with no time constraints.

While I think an exercise like this would be very revealing, finding the people to make this kind of a listening commitment has turned out to be tough.

So instead, we will have to live with the usual subjective evaluations from Mojo and friends \:\) . I'm hoping to post my comments before Sunday and then others can join in next week.

Ah, there's the engineer in you coming out! \:\)

I'm sure that more than a few of us look forward to your evaluation!

If you've ever wanted to know which of these subs has more air and snap, sounds harder or softer, which is crisper and better defined, more textured and smoother, more resonant, deeper, louder, mellower, more focused and up front, fuller or more saturating, you must act now!

And there's more! All of these qualities are revealed on a track-by-track, scene-by-scene basis for three different SPL modes: night, normal and show-off. No punches are pulled; no detail is withheld.

If you act now, you will find out details about Mojo's room, speaker positions and levels. Sub, integrated receiver and SPL details are completely revealed. Find out which sub caused infrasonic ripples on the floor above and which sub looked like it was going to come apart. Now you can discover which sub remained in full control during a 5Hz track that came with a warning from the artist; and which one bottomed out. All this knowledge for you, in the comfort of your own home.

As if all this wasn't enough, Mojo unveils his own personal musings. What kind of bass is righteous? Which sub is preferrable? Which of these two vendors is the better businessman? Which one is the better engineer? Which one has more work to do? How should you compare subs and what is the one single question that almost no one on the planet asks about their sub before they buy?

Yes, all of this wisdom can be yours. Be the first in your neighborhood to have this vast knowledge. Impress your family, friends, pets and other loved ones. Normally, a review like this would sell for a few hundred dollars. But now, it's free.

So don't hesitate. E-mail halfwattorbust@shaw.ca. That's h-a-l-f-w-a-t-t-o-r-b-u-s-t@s-h-a-w.c-a. Don't delay...act today. A virus-free, spyware-free and adware-free pdf in genuine Mojo hand-writing (sort of \:\) ) will be e-mailed to you.

I can't believe the things I do for you guys \:D .
