Five hertz and £300 separate ADAM Audio's two new subwoofers, according to the manufacturer's documented specs. In a small room, that gap may matter less than where you put the box. The two models are nearly identical on paper, so the choice comes down to a few details.
This is a decision aid built on manufacturer-documented specs. No hands-on testing was done, so nothing below is a measurement or a listening impression. Where the article infers something, it says so.
What actually differs, and what is identical
MusicTech's launch report (https://musictech.com/news/gear/adam-audio-reveals-sub8-pro-and-sub10-pro/) describes two subs that share nearly everything. Both use fibre-reinforced paper cones with rubber surrounds and 200W RMS Class D PWM amplification. Both offer AES3 at up to 24-bit/96 kHz, an XLR/TRS combination socket for analog, LFE and Wide modes, and ADAM Control management.
The differences are driver size (8-inch vs 10-inch), low-frequency extension and price.
| Spec (manufacturer-documented) | Sub8 PRO | Sub10 PRO | |---|---|---| | Driver | 8-inch | 10-inch | | Stated range | 26 Hz to 300 Hz | 21 Hz to 300 Hz | | Amplification | Class D PWM, 200W RMS | Class D PWM, 200W RMS | | Cone | Fibre-reinforced paper, rubber surround | Fibre-reinforced paper, rubber surround | | Digital input | AES3, up to 24-bit/96 kHz | AES3, up to 24-bit/96 kHz | | Analog input | XLR/TRS combo | XLR/TRS combo | | Modes | LFE, Wide | LFE, Wide | | Network control | ADAM Control | ADAM Control | | Price (GBP) | £829.99 | £1,129.99 |
Verify the price. MusicTech prints the Sub8 PRO price as "£829,99", which looks like a typo for £829.99. Check both prices on ADAM Audio's own product pages before you budget. If the figures hold, the gap is £300.
The documentation also leaves two gaps. It gives no tolerance for the frequency figures (such as a -3 dB point), so you cannot judge how 26 Hz and 21 Hz compare with other brands' numbers. It gives no maximum SPL either, so you cannot compare output between the two models.
Is the Sub10 PRO's extra extension worth it in a small room?
The documented difference is 5 Hz at the bottom end. Both amplifiers carry the same rating, so power does not separate the models.
In a small room, the first question is whether you can use that extra extension at all. This is an inference, not a tested result: small rooms tend to be dominated by room modes, which boost and cancel low frequencies at specific spots. A sub that reaches lower on paper can still leave you with bass shaped mostly by the walls. The documentation gives no room-size guidance, and this article does not invent a threshold. We cover related ground in minimal home studio gear list: how to pick every item.
The case for the Sub10 PRO is clearest if you routinely work with material near the bottom of the range, such as sub-heavy electronic music, sound design or film-style content. Your room also needs to be controlled enough to let you hear the difference.
The case for the Sub8 PRO is that it offers the same inputs, modes and networked control for £300 less, if the prices are confirmed. For many project studios, that money does more as acoustic treatment or a measurement microphone.
If you cannot say why you need 21 Hz, the documented evidence does not justify paying for it. If you can, and your room is treated, the Sub10 PRO is the logical choice. This pairs well with go deeper on finalist 2 pricing: credits vs monthly vs lifetime plan.
What DSP, ADAM Control, LFE and Wide actually change
MusicTech reports that both subs offer DSP-powered room optimisation. It also says ADAM Control, ADAM's Ethernet-based management system, lets you calibrate and monitor EQ, gain, phase and delay across the Sub PRO line, in stereo or multichannel systems. ADAM Control also works with ADAM's A Series monitors, and a video from ADAM teases support for future network devices.
That matters most if you already own A Series monitors, because one network tool may cover both your monitors and your sub. The documentation does not say how the sub integrates with the A Series for bass management, including crossover behaviour. Confirm that on ADAM's site before assuming a plug-and-play setup.
LFE Mode provides a cutoff aimed at Dolby Atmos systems. Wide Mode lets the sub operate across its full available range. The mapping that follows is an inference: Wide is probably the more relevant setting for a stereo setup where you want the sub to cover its whole range, and LFE for a multichannel system with a defined LFE channel. The documentation does not spell this out.
What DSP can and cannot fix. DSP can adjust level, phase and delay so the sub blends better with your speakers, and EQ can tame some resonant peaks. It cannot remove a deep null caused by cancellation at your listening position, and it cannot rescue a badly placed sub. Room modes, desk position and budget remain tradeoffs. Optimisation helps you tune what the room gives you, but it does not replace what the room lacks.
Who should skip a sub and fix the room instead
Skip the sub if your mixes translate poorly and your main monitors sit in an untreated room with obvious problems. Warning signs include bass that changes drastically when you move your head, or speakers pushed against a wall. A sub in that environment risks adding another source of the same problem. Spend on treatment, monitor placement and measurement first.

You might also skip it if your existing monitors already cover the range you work in and you mix mostly acoustic or midrange-focused material. A sub helps you hear and control low frequencies. It is not a general upgrade.
Pre-purchase checklist
- Inputs. Confirm your interface or monitor controller can feed AES3 (up to 24-bit/96 kHz per the documentation) or offers balanced analog outputs that suit the XLR/TRS combo socket.
- Network. ADAM Control uses Ethernet. Check that you have a free port or switch, and read ADAM's setup documentation before buying.
- A Series. If you own A Series monitors, verify on ADAM's site how the sub connects and how bass management is handled.
- Placement. Plan where the sub will sit and how you will move it while you listen. The documentation gives no placement rules.
- Price. Check the £829.99 and £1,129.99 figures on ADAM's pages, given the typo in MusicTech's text.
- Hands-on reviews. When independent reviews appear, look for measured frequency response with tolerances, maximum SPL, noise, and how well the DSP tuned a real small room.
Decision checklist by use case
- Stereo mixing, treated room, low-end-critical work: Consider the Sub10 PRO if you need the documented 21 Hz extension.
- Stereo mixing, general project studio: The Sub8 PRO is the value pick, given identical inputs, modes and networking.
- Atmos or multichannel: Both offer LFE Mode and ADAM Control multichannel management. Choose by extension needs and budget.
- A Series owner: ADAM Control compatibility counts in favour of either model. Verify the integration details first.
- Untreated small room: Address the room before choosing. Neither sub changes the acoustics.
The verdict, based on the documentation: buy the Sub8 PRO if you want a networked, DSP-corrected sub at the lower price and your room is the main limit. Choose the Sub10 PRO only if you can name the work that needs 21 Hz and your room can reveal it. Choose neither if your first job is fixing the room.
