Community Reviews

The Energy ESW C10 is a modest 10 inch powered sub that fits best with budget speaker setups and gaming, where even a basic sub can add enough low end to round things out. It is described as not too bad for the price and a sensible match for sub 1000 complete speaker packages, with easy integration through a preamp or streamer that has subwoofer output. The main caveat is that it is widely framed as underpowered and a dead end compared with stepping up to an RSL 10e, RSL 10s, or other stronger alternatives. For shoppers staying in this price tier, it is a functional but limited option.

  • The sub can work as a basic addition for PC gaming setups with KEF speakers.

    PoltaGeist

  • The sub may be a sensible match for sub-$1000 complete speaker packages from Slickdeals.

    turnne

  • The sub can integrate with a preamp or streamer using subwoofer output or amplifier pre-outs.

    Zorba1446

  • The sub may deliver acceptable perceived performance for its price when expectations stay modest.

    supermanrob

  • The sub is described as underpowered and a dead-end upgrade path that will not fix poor speakers.

    fintlewoodlewix

  • The sub is criticized as not worth buying at this price range compared with alternatives like RSL 10e.

    fintlewoodlewix

  • The sub is framed as limited for music because rear-ported alternatives may integrate better depending on room placement.

    TNFergus

  • The sub is discouraged as an upgrade because better value options exist in the same budget tier, including other powered subs.

Expensive ewaste. You're better off upgrading your speakers or saving for a real sub, not this underpowered vomit machine. Can these make poor speakers sound better? Sure. They're a dead-end path, though, as your poor speakers with this will still sound poor, and you'll still miss out on all the goodness a decent sub delivers.

For a sub? Nothing in that price range is worth a damn. For speakers? The JBL 308 recently hit about this price for one of them. I'd take one of those mono over two lesser speakers and this sub. The 308 is a path to true audiophile gear and gorgeous sound on the cheap. Once you have two of those 308, then you get the 12" Klipsch or 14" Klipsch RP sub next time it's on sale. At that point, you have a self-powered 2.1 system that will, frankly, be all you need forever, unless you want ear-damaging volumes at pristine clarity. The next significantly, cheap step up from there is room correction, which you can do yourself reasonably well with a mic and a PC. Easier with something like Dirac, of course. Even Dirac is a bit hit or miss, tbh. Then you upgrade to better speakers later. Something like hte 705p or 708p are most excellent, as are the nines. When the nines go on sale, they're an astounding bargain. The fives and sevens not so much. I consider them expensive ewaste too.

It's not that the JBL 308 are the best there are. There may be some excellent competitors out there, but they'll likely need a sub now instead of later.

Just don't buy this sub. It's a mistake.

The ones that I would consider, in order of increasing quality/performance and price:
  • dayton audio cs1200, new 239, or open box 192 (when they have stock, looks like none currently) (@parts express .com, and to some degree @amazon)
  • rsl 10e, 339 (@rsl speakers .com)
  • rsl 10s, 499 (@rsl speakers .com)
The RSLs can be had for varying amounts less when they have some in stock in their "Encore Store" (like new, or blemishes, etc -- none in stock currently), or via group purchase ("power buy") when they have enough stock and offer that option (maybe at bf/thanksgiving).

You must be a big fan of the Home Theater in a Box garbage offerings of the 2000's.

At this price, not much.
For this price, it's perceived performance actually is not too bad & relative.

Of course, paying more gives better perceived performance.
People often point to specs/measurements as proof.
The RSL10e that was brought up is also 10" with 300 watts RMS, perceived is a personal choice belief.

You hit the nail on the head
While this sub is pretty limited...it seems very sensible with the sub $1000 complete speaker packages that make front page on slick deals all the time

No doubt this is a front page deal
