The Sonos Sub Mini is the same-sector, less cost-effective soundbar upgrade I've been waiting for

The Sonos Sub Mini is the same-sector, less cost-effective soundbar upgrade I've been waiting for ...

Sonos has finally made the much-leaked Sub Mini official, and it looks like exactly the upgrade I''ve been hoping my Sonos Arc would get, bringing the full-size Sonos Sub''s dual-driver design to a smaller and more affordable version.

The Sonos Sub Mini will be available from October 6th and will cost $429/429 / AU$699. It will be available in white or black, depending on the Sonos aesthetic.

Its round design is a bit different to other Sonos products, but it still fits in nicely with Sonos'' designs. When they''re seen from above, the oval cut-out shape is the same shape as the Sonos Beam 2nd Gen and Sonos Ray. And Sonos Arc also has a round design, albeit sitting on its side rather than upright.

It''s a pesky little thing that should be easy to find a location for your TV. As you''d expect, Sonos has even added a NFC pad to the top you can tap your phone on, which makes it extra-easy to set up. However, there''s an Ethernet port if you prefer that to wireless.

Sonos claims the Sonos Sub Mini is recommended with Sonos Beam, Sonos Ray, or Sonos One units, and that while it works with Sonos Arc or Sonos Five, they already ''powerful bass'' so that it is less effective with them. However, let''s be clear, it will work with any of them, and I suspect that in a situation similar to mine, it''ll be equally well-suited to the Sonos Arc as the smaller soundbars.

I''ve used a Sonos Arc mainly because of its excellent dynamic range and excellent speakers to produce directional sound. However, the full-size Sonos Sub is too large, too powerful and too expensive to be a viable addition in my modest-sized room. However, I notice the lack of the Arc''s bass extension, especially when I compare it to other microphones I''ve reviewed before. So I used a Samsung soundbar/sub combo that included exactly the kind of small subwoofer that Sonos has

For this reason, the Sub Mini might be massive among Sub Mini owners, assuming they do well in practice (as I''ll get my transcript soon when I get it), and Sonos would probably miss a big trick if it doesn''t appeal to Arc owners, as well as Beam owners. (I am having trouble imagining many Sonos Ray owners switching to a subwoofer that costs more than the actual soundbar did, but I will test it with the Sonos Ray.)

The Sub Mini will have a sound profile altered once it''s connected to your system, so that the sub may handle the lower frequencies it has intended for, and there should be a seamless connection between them, though we''ll begin testing it as soon as possible.

If you want to adjust how much bass is involved in your setup, Sonos also provides you with a manual EQ option, and the Sub Mini will support TruePlay tuning, but you''ll need to tweak your room if you''ve already done it.

Analysis: Use the force-canceling

The price of $429 a week for the Sub Mini is significantly higher than I expected, but Samsung has included the kind of high-end technology I''d want from a small subwoofer that will perform its job fairly, which means I can''t say much.

The Sub Mini, like the full-size Sonos Sub, is designed with a force-canceling dual-driver design. There are two six-inch woofers (each powered by their own class-D amp) that promise to reach 25Hz, and they are facing directly against each other in the center, with the intention of removing unwanted additional vibrations.

When a large speaker driver like a woofer that films a lot of air in a forward direction, this produces reactionary vibrations in the opposite direction (ie, into the cabinet it''s in) every action has an equal and opposite reaction. This is what causes a large stereowoofer to rattle and shake the walls, but it''s not good for sound it''s unnecessary.

The exact same sounds are positioned exactly opposite each other in a force-canceling design. This means that when vibrations from each one knock the body that contains them, they encounter identical vibrations from the other way. The two sets of vibrations cancel each other out, leaving you with a powerful sound without the rattle.

A subwoofer can be small and relatively light, but it does also pack a lot of energy, without walking itself across the room from its vibrations.

The only noticeable disadvantage I''m not seeing the Sub Mini so far is that you can only have one unit in your system, which is a decrease from the regular Sonos Sub, which allows you to have two in one system. I thought Sonos would benefit from the same idea if you just spent the money on the big Sub instead.

The Sonos Sub Mini will be reviewed in the near future, but if you''ve got one of the finest televisions and a Sonos soundbar, it''s possible that the upgrade was completed.
