The choice between Trinnov Altitude and Anthem as a home cinema processor is one of the most common conversations we have at the specification stage of a serious cinema installation. Both are exceptional. Both are used on Custom Controls installations. And the right choice depends on the room, the speaker system, the budget and — increasingly — whether WaveForming bass management is part of the brief.

This guide sets out the honest comparison, based on our direct experience of both platforms across multiple completed installations.

The Short Version

If you are building a serious dedicated cinema room with a high channel count, complex speaker placement or a WaveForming subwoofer layout, Trinnov Altitude is the processor we recommend. Its room correction, Speaker Remapping and WaveForming capability represent the current state of the art in residential cinema processing.

If you are building a high-quality cinema room where the processor budget needs to remain sensible relative to the overall system — or where the room is less complex and Trinnov’s more advanced capabilities would not be fully utilised — Anthem (AVM 90 or MRX series) delivers outstanding performance at a significantly lower price point, with ARC Genesis room correction that is among the best available below the Trinnov tier.

Everything below explains why, and where the line falls in practice.

Trinnov Altitude — What Makes It Different

The 3D Microphone and Speaker Remapping

The defining feature of Trinnov’s Optimizer calibration system is its measurement microphone — a tetrahedral array of four capsules that maps the precise three-dimensional position of every speaker in the room: distance, height and angle, to within a centimetre and a degree of arc. No other processor at any price point does this.

This geometric data drives Trinnov’s Speaker Remapping algorithm. Most room correction systems measure what a speaker sounds like at the listening position and equalise the result. Trinnov measures where the speaker actually is and adjusts the rendering to compensate for the difference between the actual position and the ideal position. A rear surround placed 15 degrees away from its specified angle is corrected in the processor — the sound field is rendered as if the speaker were where it should be.

In practice, this means that a Trinnov installation with imperfectly placed speakers — as is the case in the vast majority of real rooms — sounds more accurate and more spatially coherent than any other processor can produce from the same physical starting point.

WaveForming

Released in March 2024 as a free software update to all existing Altitude owners, WaveForming is the most significant advance in residential cinema bass management in a decade. Using a minimum of four subwoofers placed at the front and rear of the room, WaveForming generates a planar bass wave that propagates through the room without the reflections that create standing waves and room modes. The result is bass that is consistent at every seat simultaneously — something that no amount of EQ correction can achieve from a conventional subwoofer arrangement.

WaveForming requires rooms designed around it from first fix. It is a new-build or major renovation specification. But for rooms where it can be properly implemented, it eliminates the most persistent acoustic problem in home cinema.

Channel Count

The Altitude 16 processes up to 16 channels; the Altitude 32 up to 32. For large Dolby Atmos installations — 9.2.6, 13.2.14 or IMAX Enhanced configurations — the Altitude 32 is one of very few processors capable of handling the full channel count without compromise. The Altitude 16 is the correct specification for the majority of serious residential installations up to approximately 7.2.4 or 9.2.4.

Anthem — What Makes It Right for Many Installations

ARC Genesis Room Correction

Anthem’s ARC Genesis calibration system uses a professional measurement microphone and dedicated Windows software to measure and correct frequency response across multiple listening positions. The correction algorithm applies both frequency domain and time domain corrections — addressing frequency response irregularities and time-arrival alignment simultaneously. The result is a substantially improved bass response and better inter-channel coherence than factory settings deliver.

ARC Genesis is not as sophisticated as Trinnov’s Optimizer — it does not perform geometric Speaker Remapping, and it does not have a WaveForming equivalent. But it is genuinely excellent room correction, and in a well-designed room with carefully placed speakers, the gap between an Anthem installation with good ARC calibration and a Trinnov installation is narrower than the price difference might suggest.

The AVM 90 and MRX Series

Anthem’s residential processor range divides into two lines. The AVM 90 is a dedicated preamplifier/processor — it handles decoding, room correction and preamp functions, but does not include power amplification. It is paired with separate Anthem MCA power amplifiers for a full system. For serious cinema rooms where dedicated power amplification is appropriate, the AVM 90 with MCA amplifiers is our preferred Anthem specification.

The MRX series — MRX 540, 740 and 1140 — are integrated AV receivers that combine processing and amplification in a single unit. For smaller cinema rooms, media rooms and living room cinema systems where separate amplification is not warranted, the MRX 1140 in particular delivers impressive performance in a single chassis. It is also our most common specification for living room cinema installations where simplicity and footprint matter.

Value at the System Level

A Trinnov Altitude 16 costs significantly more than an Anthem AVM 90 or MRX 1140. For many installations, the right question is not which is better in absolute terms but which delivers the most complete system within the overall project budget. A cinema room where the Trinnov processor budget comes at the expense of speaker quality or acoustic treatment is not necessarily better than a room where an Anthem processor is paired with a higher-specification Artcoustic speaker system and properly executed acoustic design.

At Custom Controls, we specify Anthem on installations where the room design is straightforward, the speaker placement is well-controlled, and the overall budget is better allocated elsewhere in the system. We specify Trinnov where the room’s complexity justifies it, where WaveForming is in scope, or where the channel count exceeds what Anthem handles optimally.

Calibration — Where Both Systems Reward Expertise

Both Trinnov and Anthem reward professional calibration and penalise rushed or careless calibration significantly more than lower-cost processors.

A full Trinnov Altitude calibration for a large system — running through the full Optimizer measurement and correction cycle — takes a full working day. We do not compress this process. The Trinnov system rewards patience: each measurement and correction iteration produces cumulative improvements that matter at the performance level these systems are capable of.

ARC Genesis calibration for an Anthem installation is less time-consuming but still requires care — the measurement positions, the target curve settings and the bass management configuration all affect the result significantly. A carelessly calibrated Anthem system will underperform a well-calibrated one by a margin that is clearly audible.

We calibrate every installation we complete — Trinnov or Anthem — using the full professional calibration process for that platform. We also offer standalone calibration for existing systems installed by other companies, regardless of which processor is in the rack.

Which Should You Specify?

Specify Trinnov Altitude if:

• The room has a high channel count — 9.2.4 or above
• WaveForming bass management is in scope for a new build or major renovation
• Speaker placement has constraints that Speaker Remapping can address
• The room is large and complex, with multiple seating rows or a challenging acoustic environment
• The project is at a level where the processor is the centrepiece of the specification

Specify Anthem if:

• The room is well-designed with controlled speaker placement and the advanced capabilities of Trinnov would not be fully utilised
• The channel count is 7.2.4 or below
• The overall budget is better directed toward speaker quality, acoustic treatment or the broader smart home system
• The installation is a media room, living room cinema or secondary cinema room where simplicity and value matter
• A single-chassis integrated solution is preferable — MRX 1140 for a clean, capable installation
