The equipment data behind the Cinema Designer: 89 speakers, subwoofers and amplifiers. Every value says where it came from and links the document. A missing value is a statement too; the model page gives the reason.

Source tags: MFR manufacturer, MEAS independent measurement, DER derived, USER user report, — not stated in the record. Maturity L1 spec sheet, L2 published, L3 verified, L4 reference.

Compare models: tick up to four subwoofers or speakers to overlay their response, output or directivity on the same axes.

The 35 W figure this record carried before 2026-09-26 was an estimate (about 70% of the 2-channel rating), not a measurement and was removed.	—Marantz publishes no 4 ohm rating and no all-channels-driven figure.	50 MFR	—the record carries no bridging statement, and Marantz's document was not re-read this round
Marantz NR1711 AV receiver	L1	7 Channels: Not stated in the record	—Marantz publishes no all-channels-driven rating (online manual and product page read 2026-09-26). No independent bench test of power was found; the one ASR member thread measures the pre-outs only. The 30 W figure this record carried before 2026-09-26 was an estimate (about 60% of the 2-channel rating), not a measurement and was removed.	—Marantz publishes no 4 ohm rating (lowest rated load 6 ohm) and no all-channels-driven figure; no bench test found.	50 MFR	—the record carries no bridging statement, and Marantz's document was not re-read this round
Marantz SR7015 AV receiver	L2	9 Channels: Not stated in the record	—Marantz publishes no all-channels-driven rating (online manual and product page read 2026-09-26). ASR measured 2 channels only; no Audioholics bench test exists. The 85 W figure this record carried before 2026-09-26 was cited to an Audioholics bench test (audioholics.com/av-receiver-reviews/marantz-sr7015) that does not exist and was removed.	—Marantz publishes no all-channels-driven figure; ASR measured 4 ohm with 2 channels driven.	125 MFR	—the record carries no bridging statement, and Marantz's document was not re-read this round
Marantz SR8015 AV receiver	L3	11 Channels: Not stated in the record	—Marantz publishes no all-channels-driven rating (it guarantees 70% of the 2ch rating for up to 5 channels, per Audioholics). The most channels any bench test drove is 7 of 11 (Audioholics, 101 W at 1%, recorded as power_rated_8ohm with channels_driven 7). The 95 W ACD figure this record carried before 2026-09-26 was not in the Audioholics review, which measured 7 channels, not all 11, and was removed.	—Marantz publishes no all-channels-driven figure; ASR and Audioholics measured 4 ohm with 2 channels driven.	101 MEAS	—the record carries no bridging statement, and Marantz's document was not re-read this round
Trinnov Amplitude16 Power amplifier	L2	16 Channels: Not stated in the record	—Trinnov publishes no per-channel all-channels-driven figure, only totals: "2800W all channels driven @40°C continuous, 120 VAC (SE or BTL)" and 3200 W at 230 VAC (manual, read 2026-09-26). Audioholics measured up to 7 of 16 channels (200 W/ch at 8 ohm, 20 Hz - 20 kHz, <0.1%).	—No all-channels-driven 4 ohm figure is published; Audioholics tested 4 ohm with 2 channels only.	200 MEAS	Yes MFR
Trinnov Amplitude8 Power amplifier	L1	8 Channels: Not stated in the record	225 MFR	375 MFR	—Trinnov publishes only the x8 figure.	No MFR
Wharfedale PRO DP-4100N MK2 Power amplifier	L1	4 Channels: Not stated in the record	1000 MFR	1700 MFR	—Wharfedale rates all four channels driven only.	Yes MFR
