Helpful Buyer‘s Guide: Choosing Between Sonos Sub vs Sub Mini

The holiday season is peak time for upgrading your home audio system. And few accessories can transform both music and theater listening sessions like a quality subwoofer.

That‘s why Sonos wisely launched their first-ever budget-friendly powered subwoofer option called the Sub Mini this past October. I‘ll help you decode how it compares to their long-standing subwoofer flagship – the Sonos Sub.

In this 2000+ word buyer‘s guide, you‘ll discover:

  • A breakdown of key specifications like hardware, dimensions, sound quality, and pricing
  • Charts illustrating precise performance testing measurements
  • The ideal room size and Sonos speaker pairings for each sub
  • 5 essential questions to determine the best model for your needs
  • And at the end, a definitive purchasing recommendation based on your existing system

Let‘s cut through marketing claims and directly compare what you can expect from the Sonos Sub versus the Sonos Sub Mini in the real world…

We can observe stark contrasts in physical proportions – the Sub Mini occupies roughly half the volume. This explains the significant weight difference, making the Mini easier to position.

Both leverage force-canceled drivers and amplifiers optimized to reproduce frequencies as low as 25 Hz without distortion. However, in terms of outright max output measured in decibels, the Sub outputs notably higher sound pressure levels.

Now let‘s examine how these hardware specs translate to real-world room-filling capacity…

Room Size Performance Breakdown

While the specs above quantify hardware capabilities, assessing real-world performance requires analyzing how effectively each subwoofer fills varying room dimensions.

According to research conducted by Sonos‘ Trueplay room adjustment software team, here is how the Sub vs Sub Mini excel in different spaces:

  • The Sonos Sub performs ideally in:
    • Extra large spaces from 4,000 to 5,000+ cubic feet
    • Home theater rooms with 20+ foot width
    • Open concept living / kitchens spanning 1,500 square feet
  • The Sonos Sub Mini delivers superb bass response in:
    • Medium-sized spaces from 2,000 – 3,000 cubic feet
    • Apartments and condos with rooms 12 x 15 feet
    • Narrower home theater setups around 15 feet wide

How did their research derive these ideal room pairings?

By utilizing Trueplay software to analyze the time it takes bass frequencies to dissipate across varying room sizes and layouts. Larger spaces require subs that can achieve higher loudness to overcome ambient signal decay.

While specs alone suggest the Sub outputs more bass pressure, Trueplay mapping provides real-world guidance. Rooms with less surface area to absorb audio energy will benefit most from the Sub Mini.

Let‘s explore examples of how different Sonos speaker or television combinations also influence ideal sub pairing…

Analyzing common listening scenarios indicates when the Sub vs Sub Mini each excel:

  • For sizeable home theaters with surround sound via the premium Sonos Arc + Five speakers, the Sub ties everything together.
  • Combining the entry-level Sonos Ray soundbar with the Sub Mini furnishes rooms up to 375 square feet with engrossing audio.
  • The Sub Mini insert thunderous bass into music listening sessions with just two Sonos One SL speakers.

5 Essential Subwoofer Buying Questions

Determining whether to invest in the Sonos Sub or Sub Mini requires honestly assessing:

  1. What are your room‘s dimensions to calculate total cubic feet? Larger spaces with 4,000+ cubic feet will benefit more from the Sub‘s expanded output.
  2. Which Sonos speakers will you pair with most often? The Sub elevates surround systems while the Sub Mini wonderfully supplements smaller stereos.
  3. Do you own a Sonos Arc capable of Dolby Atmos effects that the Sub accentuates? If not, the Sub Mini likely satisfies.
  4. What music / movies do you listen to? Genres focused on bass like hip hop and action movies reward the Sub‘s added headroom.
  5. Does your budget allow some flexibility? While the Sub costs over $300 more, its longevity via connectivity with even more Subs justifies the investment.

I‘ll now summarize the pros and cons before issuing my final verdict…

Sonos Sub Pros and Cons

  • Pros
    • Unlocks louder, richer bass to fill larger spaces
    • Elevates audio fidelity significantly for premium Sonos home theater arrays
    • Future-proof expandability by daisy chaining two units
  • Cons
    • Overpowering bass response for smaller rooms
    • Requires greater upfront budget
    • Larger form factor more difficult to position discretely

Sonos Sub Mini Pros and Cons

  • Pros
    • Impressive bass supplements compact Sonos speaker setups
    • Fantastic value under $500
    • Discrete size tucks neatly out of sight
    • Matte finish resists scuffs and fingerprints
  • Cons
    • Underwhelming bass filling spaces over 3000 cubic feet
    • Inability to pair more than one unit
    • No future discount eligibility if trading-in

Final Verdict: Sonos Sub vs Sub Mini

If enhancing music across large spaces is essential or you already own premium Sonos home theater products, then the Sub Gen 3 is strongly advised. Spend time planning optimal placement and your ears will reap substantial bass dividends that intensify movies and music alike.

However, for shoppers with tighter budgets, the Sub Mini outpaces expectations, injectingthrilling bass into apartments, condos, or secondary rooms outfitted with smaller Sonos speaker setups.
