Most consumers only think about “bass” when they hear the term “subwoofer” and that’s a huge failure on the part of the hi-fi press for not doing a better job of educating potential customers about their other benefits. SVS and REL Acoustics are two of the leading brands in the category and it’s clear from their websites and educational videos that they understand it is their job as well to do some of the heavy lifting. It’s not enough to just introduce new products like the REL HT/1003 MKII “The Hammer” ($699) and the HT/1205 MKII “The Cannon” ($849) subwoofers for home theater.
You have to explain to people why they need them. How many consumers even understand the rationale for using a stereo pair of subwoofers and why that might work better for them in their room than one larger one?
REL has been manufacturing high performance subwoofers for decades and done remarkably well with its best-selling T/x series product line, HT/1510 Predator II and No.31 and No.32Â reference subwoofers which are designed to augment the world’s best hi-fi and home theater systems. The T/x models have always been rather affordable but the vast majority of consumers who purchase them are thinking about 2.1 stereo systems or 2.1 home theater rigs; home theater fans often turn to brands like SVS or Klipsch when it comes to 5.1 or 5.2.4 Dolby Atmos systems.
REL has announced new entries into its HT subwoofer line, which seem to offer rather affordable alternatives to the competition.
One thing we often neglect to consider with subwoofers is that their purpose is not only to provide impactful bass, but they should also add balance to your home theater setup by sonically integrating smoothly with the other speakers in your system. You should not perceive any gap between the subwoofer and the rest of your speakers.
One benefit from our experience with RELâs subwoofers is that they do sonically vanish once properly installed, improving both the dynamic range, clarity, and soundstage of your existing loudspeakers.
RELâs subwoofers are a particularly great complement for 2.1 music systems, but they are also a great addition to a home theater setup.
HT/1003 and HT/1205 MKII Overview
The HT/1003 MKII and HT/1205 MKII subwoofers are updated versions of REL’s previous HT/1003 and HT/1205 subwoofers. In general, some of the improvements include:
- New Class D amplifiers that provide greater headroom. REL claims that the HT/1003 MKII can play twice as loud as its predecessor while the HT/1205 MKII can play 50% louder.Â
- Tweaks to the components used in the construction of the CarbonGlass driver of each sub including upgraded suspension.
- Additional tweaks to supporting circuitry that limits distortion and improves frequency response clarity.
- Tweaks to the exterior cabinet design including a new black lacquer finish for better integration with room decor.

Hail and well met, sir!
I do not know why, but every front-firing subwoofer I have bought has vibrated itself stoopid. Most of them were (*GASP*) Klipsch but a couple were from other manufacturers whose name(s) escape me right now.
I now only use down-firing subs, with my favourite being a 10″ Martin-Logan (it came to me after I walked over and looked at it!). Yes, ’tis the plebe model! đ It is most likely just bad luck or the god (small “g”) of Bass (Hz not the fish) despises me. Any thoughts on this (MMS term ALERT!!!!) Cambiata (for me) of a “crisis”. That, I must admit, was a stretch.
