RSL Speedwoofer 10S Subwoofer Sound Quality Tests

By

My listening took place in a large open room.  The majority of my listening consisted of two Speedwoofer 10S running in tandem, one placed in each front corner.  Compared to a single subwoofer, this provided slightly more dynamic headroom and, of course, better seat-to-seat bass consistency.  That said, the overall sound character of a single sub remained similar to my notes for dual sub listening.

For movie listening, I fired up the final installment of the Hunger Games series, Mockingjay Part 2.  There’s nothing like a futuristic war movie to offer up some punchy, impactful bass thanks to explosions big and small.  I found the Speedwoofer 10S to provide a tactile experience, with dynamic bass that you can feel in your chest.  It’s that “feel” that imparts realism in a movie going experience, and RSL delivers.  While the Speedwoofer 10S may not have the deepest rated extension with a -3dB point at 24Hz, the low-end reproduction is better than expected at this price point, and the quality and quantity of the midbass is superb.

My music listening started with one of my favorites, “Be Brave” by My Brightest Diamond.  I choose this track because a solid kick drum and tom beat allow me to hear how accurately subwoofers reproduce organic sounds.  Subwoofers that value big dynamics at the expense of articulation will reproduce a dull “thump” instead of a clean, fast, “real” sounding instrument.  The Speedwoofer 10S was properly weighty with the aforementioned impact that you can feel, but also had a nice tight decay and could handle more subtle bass microdynamics.  In short, it sounded “real.”

Still, there’s nothing quite as exciting as a big, in your face, bass line, which is why I went through several spins of Bjork’s “Hyperballad.”  No only does this track feature a huge, powerful chorus, but there’s a steady, low 3-note bass pattern that is just this side of a sine wave torture test for subwoofers.  Thanks to the use of multiple subs, no one frequency rang noticeably louder than another, either at the main listening positions or at the secondary positions.  Having a compact and capable, yet affordable sub like the RSL Speedwoofer 10S dramatically drops the entry price for multiple subwoofers setups allowing more audioholics to get accurate, even sound in every position.

We have owned the Speedwoofer for about 9 months now. It is paired with a JL E-Sub e112 (granted - not a fair pairing - as the JL never hits notes it can't handle … however with 1 sub in a big room, to get full effect it actually hurts your ears if turn it up to much) so to get a fuller effect I thought i'd pair it with the ported Speedwoofer. It did provide a much fuller base level for a variety of listing formats from music to movies. However, in the past week we played a newer movie that has an exceptional amount of unnaturally low base. The result was i had turn (within a few minutes) the base setting back on the Speedwoofer as low as they would go … as it was pure distortion. Today i'm listening to simple acoustic on Spotify - and i can here distortion and creaking from the Speedwoofer case. It sounds like the insides have been shaken loose. I've noticed the distortion from normal recordings if played loud. So the bottom line: There is a definite downside limit when it comes to pairing subs … and i unfortunately exceeded it.

Main system: Marantz SR-7013, Aperion Grand Center, DCM TimeWindow 7 mains, PSB Atmos, Aperion Tower rears (Grand - small - discontinued). Area of use is BIG open room (spacial equivalent of a triple living room)

A 10'x10' room is bound to have some very heavy standing waves. I don't think any particular brand of sub is going to help you in there. What could help is a multi sub approach.

I was looking at this too, my room is 10x10, just for music and i have a BIC f12 and feel like its horrible for music. Running polk monitor 40s and a Yamaha reciever. My budget is $400…but keep hearing mixed reviews…

Okay, so I'm about to upgrade from a Dayton Sub-1000. I think the RSL SW10S might be perfect (for a large room and mostly bassy music use), but some seem to suggest that the BIC PL-200 ii might be nearly as good. Others suggest moving up to the SVS PB-1000. (There's also a SB-12NSD I might still be able to snag for < $450….) Any thoughts?
