Subwoofer ratings by Widescreen Review mag


This forum receives a number of inquiries about "which subwoofer should I buy". There are a number of technical and practical (size, cost, etc.) issues which must be considered by anyone looking for a good subwoofer, but I don't intend to try to cover those considerations here.

Widescreen Review magazine conducted a series of subwoofer evaluations between 1997 and 2000 (which obviously leaves out some of the most recent models). I thought that readers might find a list of the "top twelve" subs rated by WR to be a useful starting point when contemplating the purchase of a new/used subwoofer. You will note that this list does not include the REL brand, since none of them were reviewed in this group of articles. The reviews, however, did include the Sunfire "True Subwoofer" Mk 2, which finished in the middle of the pack of the 50 subs.

The review articles rated 50 subwoofers for 12 factors, and scored them from 5 (highest) to 1 (lowest) on each factor. The rated factors were: music (ability to faithfull reproduce music); effects (ability to faithfully reproduce LFE); impact; tonal definition; overhang (tight vs. flabby bass, with tight being the desired property); rhythm and pace; midrange coloration; enclosure integrity; distress (how the sub performed under severe stress); subjective deep bass; ability to play at 105db or louder at 35 Hz; and ability to reproduce 25 Hz frequencies cleanly.

The highest possible score for a subwoofer would be a perfect 5.0. The subs are listed below, in alphabetical order:

Only one subwoofer had a perfect 5.0 score:
1. Linn AV 5150 (price: $4200)

The best group of subs had nearly perfect scores, with only a few factors rated less than 5, and none lower than 4.0. When looking at the average score, you should also note the price when making comparisons:
1. Bag End Infra-18: average = 4.92 ($2400-2900, depending on finish)
2. B&W ASW4000: average = 4.71 ($3000)
3. Earthquake SuperNova Millenium 15: average = 4.71 ($2000)
4. Energy ES-18XL: average = 4.875 ($1700)
5. Mirage BPS-210: average = 4.92 ($1700)
6. Mirage BSP-400: average = 4.71 ($1300)
7. M&K MX-5000THX: average = 4.83 ($2500)
8. M&K MX-700: average = 4.67 ($1400)
9. Vandersteen 2Wq: average = 4.83 ($1300) (this sub is specifically intended to be used in pairs, which would increase its average score to that of V2W)
10. Vandersteen V2W: average = 4.96 ($1300)

SD,

You did a nice job compiling all those scores. I think the special sub issue of Widescreen Review is a good place to start when one is thinking about buying a subwoofer—it contains a lot of information. However, people should keep in mind that the reviewer, Richard Hardesty, like any reviewer, has very specific preferences. He admits that he has such preferences, and warns readers that they may have different preferences. In other words, the reviews are just one person's opinion.

For instance, he generally prefers sealed enclosures over ported ones, especially for music. He also strongly recommends two smaller subs in stereo over one large sub using a mono signal. Those are valid preferences--but not everyone shares them. I wouldn’t necessarily recommend a small sub simply because it is easy and cost effective to add a second one and have a stereo set-up. You could very well end up with two subs that have limited output and are easy to bottom out. I also prefer my ported sub over my audiophile sealed sub hands down, for both music and movies. Those are my preferences but who cares? The point is you should always listen and decide for yourself what design works best for you.

Anyway, the sub issue does encourage buyers to listen more critically to subwoofers, and it provides criteria by which to judge them. That’s a good thing. I just think you have to keep the ratings in perspective.
Steel: I absolutely agree with your comments. Hardesty does have a stated preference for subs with sealed enclosures -- one which I happen to share, since my preference is for music over LFE/HT applications. Ultimately, it's a matter of individual taste, and any sub should be auditioned in the home listening environment if at all possible, since the way a sub loads the room will vary from sub to sub, and room to room (event the same sub in the same room will load differently when you move it as little as 6 inches).

Since the time of the Widescreen Review articles, there have been some significant improvements in subwoofer technology implemented by a number of speaker manufacturers, the most noteworthy of which is parametric equalization. Companies like Vandersteen, Revel and Infinity now all offer such subwoofers. The most recent improvement is the introduction of software programs which assist the "audiophile" in both subwoofer placement and adjustments of the parametric equalizers. The Revel B-15 is especially flexible in this manner, with three such equalizers that are variable in terms of frequency, amplitude and bandwith, as well as variable phase--all well integrated with Revel's new LFE software.
