A single sealed cabinet that claims to reach 20 Hz sounds like the end of the subwoofer. Then you see the price: £5,999/$7,499/€6,999 for one speaker, and you need two. Is the HEDD TYPE 40 a sensible upgrade from nearfields, or an expensive answer to a problem your room cannot let it solve?
This piece uses the TYPE 40 as a worked example of the single-cabinet full-range approach and weighs it against nearfields plus a sub. Every HEDD figure below comes from MusicTech's launch report and is a manufacturer claim. Nothing here is a hands-on result, and wherever a decision depends on your room, this piece says so.
What you are actually comparing
The TYPE 40 Main is a compact sealed three-way active monitor. According to MusicTech, HEDD aims it at mixing and mastering suites, post-production facilities and larger control rooms, as full-range reference from one cabinet with no separate sub. It targets studios that need more level, low-end reach and listening distance than nearfields offer, but lack space for a traditional large-format main system.
That positioning matters. HEDD does not pitch the TYPE 40 as a bigger nearfield. It pitches it as a replacement for the whole nearfield-plus-sub chain, with a modular route for studios that need more than one cabinet delivers.
The modular part is the XTD. Per MusicTech, each XTD module holds a 10 3/4-inch high-excursion woofer with a 700W Class D amplifier, and up to three stack beneath each Main. The XTD costs £5,699/$6,999/€6,499 per unit.
Bass extension and output: claims to check
HEDD says the Main's high-excursion woofer and sealed enclosure reach 20 Hz, and that its Class D amplification delivers peak output of up to 123 dB SPL. It also says three XTDs in Frontfire Ported mode raise maximum SPL at 50 Hz by up to 15 dB compared with the Main alone.
Those are headline numbers, and MusicTech's report leaves gaps. It does not state the tolerance for the 20 Hz figure, the measurement distance for the 123 dB peak, or the test conditions behind the 15 dB gain. Ask HEDD or a dealer for the full response curve and the conditions. "Reaches 20 Hz" can mean very different things at -3 dB and at -10 dB.
A nearfield-plus-sub system makes no such single claim. Its low-end reach depends on which sub you choose, where you put it and how you set the crossover. That is a general principle, not a HEDD claim. It means you should audition the exact combination rather than trust two separate spec sheets.
Room size, treatment and rear-wall placement
Here the single-cabinet idea meets physics. A speaker that extends to 20 Hz in a small room excites room modes, and no monitor design removes those. Treatment, speaker position and listening position decide whether the extra low end becomes usable information or a boomy mess. This is a general acoustic principle, and it applies to any full-range speaker.
HEDD's cardioid option targets one specific problem. MusicTech reports that selectable Cardioid configurations cut energy radiating behind the speakers, reducing rearward radiation by up to roughly 10 dB depending on configuration. A single closed Cardioid XTD provides directional control from about 20 to 200 Hz. Larger systems combine Frontfire modules with a Cardioid one.
The practical read below is an inference, not a HEDD claim. Cardioid control should help most when your speakers sit close to a rear wall and you cannot pull them out, because it reduces the rear-wall reflection contribution. It does not promise to cure modal peaks and nulls at your listening position, so measure before and after.
The XTDs also switch between Ported and Closed operation with a port cover. Ported mode favours efficiency and maximum output. Closed mode favours control, definition and resolution. Small rooms probably need maximum output less than they need control, so the Closed mode claim is the one to hear first.
Listening distance and workflow
Nearfields suit short listening distances and rooms where reflections arrive early. Move back, or ask for higher levels, and a larger main starts to make sense. HEDD's own positioning cites more level and listening distance than nearfields as the gap the TYPE 40 fills. If you sit close in a small room and mix at moderate levels, you may be paying for headroom you never use. See related: rotary dj mixer vs standard mixer: which suits you? for additional background.
For mastering and critical mixing, the case for full-range gets stronger. The TYPE 40's Lineariser has three modes, per MusicTech:
- ZERO PHASE corrects amplitude and phase and aligns the system in time.
- FLAT keeps the frequency-response correction without phase linearisation.
- OFF gives the lowest latency for tracking and real-time performance.
MusicTech's report gives no latency figures for any mode. If you track through your monitors, or monitor live performers in the room, ask for the numbers and listen in OFF mode. With nearfields plus a sub, latency depends on any DSP in the sub or crossover, so check that too.
Integration and control
Nearfields plus a sub mean managing crossover, level matching, polarity and time alignment between two different speaker types. A careful setup can work very well, but it takes measurement and patience. That is a general principle, not a product claim.
HEDD says the Main and all connected XTDs operate as one time-aligned system. Its HEDD CTRL software manages every unit over Ethernet. Once you choose the physical configuration and XTD modes, the software applies the correct LF Range and Extension Qty settings automatically.

CTRL also offers a 12-band parametric EQ at group and individual speaker level, plus presets for workflows, formats, clients or listening positions. HEDD says it scales from a stereo pair to an immersive installation of up to 250 speakers.
That should reduce setup guesswork. It does not remove the need to measure your room, and MusicTech's report does not describe how well the automatic settings perform in difficult spaces.
What a pair really costs
The arithmetic below uses HEDD's per-unit prices from MusicTech's report. It excludes stands, mounting hardware, cabling, taxes, treatment and any dealer discounts.
| Configuration | £ | $ | € | |---|---|---|---| | Pair of Mains | 11,998 | 14,998 | 13,998 | | Pair plus one XTD per channel (2 XTDs) | 23,396 | 28,996 | 26,996 | | Pair plus three XTDs per channel (6 XTDs) | 46,192 | 56,992 | 52,992 |
A nearfield-plus-sub system has no single price. It varies with the monitors and sub you pick, so price your own shortlist against the first row.
The cost structures differ too. A modular system lets you spend in stages, but each XTD costs nearly as much as a Main. Nearfields plus a sub let you upgrade the sub or the monitors independently.
Side-by-side comparison

Decision checklist
Work through these in order. The guidance is general, not a HEDD claim.
- Room size. Small room, sitting close, modest levels: nearfields plus a sub is usually the safer spend. Larger room or longer listening distance: a full-range main deserves serious consideration.
- Rear-wall position. Speakers stuck near the wall with no room to move: look hard at the cardioid configurations. Free-standing with space behind: the cardioid benefit probably shrinks.
- Budget. If a pair of Mains already stretches you, adding XTDs is out of reach. Put money into treatment and measurement first.
- Workflow. For mixing and mastering, audition ZERO PHASE and FLAT. For tracking, audition OFF and confirm its latency.
- Growth. If you may add immersive monitoring or more bass output later, the modular route lets you spread the cost.
Verify before you buy
Ask for the full frequency response of the Main, including the tolerance behind the 20 Hz claim. Ask what distance and signal produced the 123 dB peak figure, and what conditions lie behind the 15 dB gain at 50 Hz. Audition in a room similar to yours, ideally your own, with a dealer who will take the pair back.
Measure your current room first. If you do not know where your modes and rear-wall reflections sit, you cannot judge what extra low end or cardioid control will fix. If you go modular, compare Closed and Ported XTD modes by ear. Listen to all three Lineariser modes on material you know.
Request latency figures for tracking, and confirm what the quoted price includes.
Pick a single Main if you have a mid-size treated room, mix or master at longer distances, and value one time-aligned, software-controlled system. Add XTDs only if your room and budget demand more output or rear-wall control. Stay with nearfields plus a sub if your room is small, you sit close, or the £11,998/$14,998/€13,998 for a pair of Mains would crowd out treatment. HEDD's claims make the TYPE 40 a credible option, but only your room and your ears can confirm it.
