- Paradigm Defiance V8 Subwoofer
A compact entry-level sub, with 8" driver, ported cabinet, 75 W rms and 150 W peak dynamic power from a class-D amplifier, soft-clip limiter that prevents overdriving.
The Paradigm Defiance V8 Subwoofer is a capable sub for two-channel applications or smaller systems needing help down to the 30 Hz range. Not a cinema foundation-shaker, the V8 can deliver peak levels of 104 dB at 40 Hz and 110 dB at 80 Hz @ 1 m. Its soft-clip feature ensures clean performance under any condition.
Appearance and Features
The Paradigm Defiance V8 is a ported subwoofer with an 8-inch driver, dressed in a plain satin-black woodgrain finish, with a detachable black grille, a tuned port on the bottom, and the standard complement of controls and inputs on the rear-mounted amplifier. As one would expect with a manufacturer like Paradigm, the fit and finish were excellent. The V8 is not going to steal the show with its appearance, but its sound performance will not be easily forgotten.
The grille is built a little tougher than one might expect. I have seen grilles flimsy enough to break if mishandled even slightly, but that is not a worry with the little V8. Not that grille strength is a major concern, but I see it as a sign of the overall toughness of the unit. Knocking on the wood surfaces revealed no troubling resonances.
The control panel includes LFE and Line inputs, plus L & R speaker level inputs for the user who wants to add a sub to a smaller system without a receiver and bass management, Auto/On for power, a Phase switch, Volume and Crossover Frequency controls, power cable attachment, and a Status LED.
The V8 is designed to cover the range of 34-200 Hz +/- 3 dB, with -10 dB extension down to 28 Hz. This will not impress the cinema buffs, but the 2-channel user who wants another octave of bass from his system might find it to be just right for the task. The power amplifier is a Class-D design, with 75 W rms and 150 W dynamic peak capability. The bigger units in the series allow the option for Anthem Room Technology, room correction for the low frequencies covered by the sub, but the feature is not available on the budget-targeted V8.
The V8 weighs in at an easy 26.5 lb, and will fit in almost any small spot in your listening room with its 14 3/16” x 12 3/4” x 14 1/8 “ dimensions.
It is well-established fact that more subs are better than fewer when it comes to evening out those dreaded room modes and reflections/cancellations that plague most systems in the LF range. The addition of a third sub, a v8, to a system with 2 subs already (of roughly the same capability level) is a good option for evening out those lows. Or, for a new system, a duet or trio of V8 subs might be an approach to consider, although for the money a user might consider moving up the line to a more capable subwoofer with some room correction, either the optional ARC or a system-level package like Dirac Live.
Having two subs already, with some of the aforementioned bass unevenness with my unequalized system, I briefly tried the addition of a V8 to even out the modes. The result was quite effective, although chasing room modes is not my idea of a good time. I lean more toward two better subs plus room correction for my room.
The CEA-2010 Subwoofer Test standard helps us determine what amounts to the beginning clip level for the sub under test, but a feature of the Paradigm Defiance V8 prevents the standard from being followed to the letter. A soft clip feature in the subwoofer amplifier design, which amounts to a limiter of sorts, limits the volume level at just below the point where the distortion harmonics would trigger the thresholds in the CEA-2010 spec. The soft clip levels that approach those thresholds are documented below. You can see that the V8 is capable of putting out 104 dB at 40 Hz and 110 dB at 80 Hz at 1 meter distance.
Music Listening Tests
(Chemical Brothers, Astralwerks)
Listening was all done with no room correction and with only the one V8 and an 80 Hz crossover setting.
The B-52’s: "Good Stuff"
The walking bass line through this track is a good listening test for LF response. All the notes of that line sound smooth and even through this track with the V8 subwoofer. The bass sound in general is solid and quick.
The B-52’s: "Revolution Earth"
The bass had an almost tonal quality about it, like some frequency response resonance is influencing every note. This was the only track where I heard that effect.
The B-52’s: "Vision Of A Kiss"
The bass and kick drum through this track sound right on target, exactly as they should.
The Chemical Brothers: "Reflexion"
The lows in this electronic track go nice and deep and the V8 handled them with ease. The V8’s built-in soft-clip limiter will hold back on the lows rather than let them distort, a protection for the sub itself and rarely noticeable if ever in normal use.
The Faint: "Child Asleep" and "Chameleon Nights"
Solid bass, easy to forget one is reviewing one. Nice.
Chiara String Quartet: "Bartok String Quartet No. 2, Op. 17, Sz. 67: II. Allegro molto capriccioso"
Only the lowest cello notes reach the range covered by the V8, with the crossover at 80 Hz. Nothing standing out, nothing missing, just right.
Danish String Quartet: "J.S. Bach, The Well-Tempered Clavier: Book 2: BWV 870-893 - Fugue in E-Flat Major, BWV 876"
Another example of smooth, even bass from the cello.
F. Reiner: "Chicago Symphony Orchestra: "Beethoven, Symphony No. 7, in A, Op. 92-2 - Allegretto"
This recording was made with a stronger bass balance than many orchestral performances, and begs to be played with energy, especially in the more climactic passages. Even when pushing the volume, the V8 never gave a complaint, it played smooth and even all the way through.
The three passages mentioned above, plus the rock and electronic tracks, confirmed the V8 can handle subwoofer duties in a variety-centric two-channel system.
Cinema Listening Tests
The depth charges push the low frequencies mainly in the 40 Hz range, perfect for a little LFE impact action by the V8. Designed to never bottom out or clip or turn to fuzz, the V8 helped deliver respectable explosions.
The Paradigm Defiance V8 Subwoofer strikes me as an excellent addition to a small- to mid-sized 2-channel system or a humdinger of a sub for a desktop computer music system. It will never clip or overdrive with its built-in soft-clip protection. With extension down to 28 Hz, it simply will not put out the lows needed for a kick-your-seat cinema system, like its bigger brothers in the Defiance Series. But at the price point, with moderate volumes and mainly music to deliver, the V8 is a steal of a deal of a subwoofer.

Compression Indicted By CEA-2010 Test
With the built-in soft-clip protection, the V8 can not be tested to the CEA-2010 standard. The distortion level determined during the test is never reached. The measured input and output levels and the resulting compression are as follows:
