The Nines II balanced analog inputs
Klipsch, Maker specs, checked October 4, 2026
Official model-specific support resolves the omission in the specification sheet. Two combo balanced inputs accept XLR or quarter-inch TRS. A compatible balanced source is required. This does not establish microphone amplification or instrument input.
The Nines II My Input buttons
Klipsch, Maker specs, checked October 4, 2026
Two buttons save supported sound mode, EQ, source and playlist or station. Shared with Fives II and Sevens II.
The Fives II My Input buttons
Klipsch, Maker specs, checked October 4, 2026
Two programmable buttons recall supported sound mode, EQ, source and playlist or station. This is shared with Sevens II, not a reason by itself to buy the larger model.
ORA4, not original ORA. RCA line, USB-C audio and Bluetooth. Automatic 80 Hz high-pass and low-pass filtering when a subwoofer is connected. 4.7 W by 6.7 D by 8.3 H inches. No room-size or measured sound comparison inferred.
HDMI ARC with CEC, RCA line, auxiliary, optical and USB-C audio. Separate USB-C charging port. Automatic 80 Hz crossover. Night and vocal modes are control functions and do not treat hearing. 7 W by 8.5 D by 10.9 H inches.
Explicit generation columns establish original TUK phono and headphone output, absent on Grand G2. Original USB-B versus Grand USB-C audio. Do not use inconsistent Bluetooth version or percent-power marketing for a buying claim.
Manufacturer-authored original manual preserved by a manual host. Separate phono and line inputs, headphone output and swappable active channel. Original channel selection resets to left after a power cycle. Not a G2 manual.
Six-inch woofer, two RCA line inputs, USB-C audio, optical and Bluetooth. No phono stage or headphone output. Swappable active speaker and selectable 80 Hz filtering. 8.6 W by 11.6 D by 13.8 H inches. Selected US finish is Matte Black with Gunmetal.

YU4 5.5 W by 7.5 D by 8.7 H inches. YU6 6.9 W by 8.1 D by 10.7 H. G2 USB audio, crossover and placement features are not transferred.
HDMI ARC, optical and USB-C audio, network streaming and subwoofer output. Mandatory wired interspeaker connection. 240 H by 155 W by 180 D mm. No analog line input.
One mains connection, secondary powered over included 3 m C-Link. Optional 8 m C-Link. Network setup, updates and restrictions on guest or authentication networks. Do not claim ordinary USB charging cables are interchangeable with C-Link.
Original LSX II, not LT. Analog 3.5 mm line input, HDMI ARC, optical, USB-C and network streaming. Wired or wireless interspeaker connection. Same 240 H by 155 W by 180 D mm body as LT.
Both speaker cabinets require mains power. Wireless interspeaker use removes the linking signal cable. Both power cables stay. Analog input is line level and has no moving-magnet phono stage.
Separate MM phono and RCA line inputs, HDMI, optical, USB-C computer audio and Bluetooth. No built-in Wi-Fi music streaming. Wired C-Link between speakers, one mains lead. 285 H by 168 W by 268 D mm. Bluetooth codec support depends on source compatibility.
HDMI eARC, optical, coaxial, analog line and network streaming. USB-A is for service only and does not take computer audio. Wired or wireless interspeaker link. 305 H by 200 W by 311 D mm. No audible improvement inferred from sample-rate ceilings.

HDMI 2.1 passthrough with stated 4K/120 Hz, VRR and ALLM support. Actual source, TV and cables must support the desired format. HDMI input and TV eARC output are distinct ports.
Exact selected US part 1080243. 15 H by 8.12 W by 12.5 D inches, optional wireless interspeaker connection, microphone and limited Dirac license included. No full-band Dirac license assumed.
Exact selected US part 1080249. 18.13 H by 9.62 W by 14.75 D inches, 8-inch woofer, wireless link and limited Dirac license. Secondary kilogram typo is excluded. Balanced inputs are separately established by the model-specific support article.

The Sevens II Dirac setup
Klipsch, Maker specs, checked October 4, 2026
Calibration requires a quiet room and several measurement positions. Supplied microphone must be unplugged for playback. Room correction does not soundproof a room or guarantee less disturbance next door.

RCA and 3.5 mm analog inputs remain active together. USB is 5V charging only. No built-in Bluetooth or headphone output. Active body 10.75 H by 7 W by 9 D inches. Guide recommends six inches behind speakers. No physical-input switching inferred.
4.5-inch model, HDMI ARC, USB audio, optical, Bluetooth and switchable RCA phono/line, sub out. 5.5 W by 8 D by 9.625 H inches. One powered cabinet and wired passive speaker.
Rear input and phono switch, computer USB and TV setup. RCA line and phono share one physical pair. Page 8 confirms selectable side. The L/R switch refers to the speaker-output terminals, so follow the diagram rather than assuming the marked letter is the powered cabinet channel.
6.5-inch model, HDMI, USB computer audio, optical and Bluetooth. 205 W by 243 D by 330 H mm. Product page says eARC while the manual and rear label say ARC, so no eARC advantage is published.
Rear-panel diagram confirms ARC, selectable active-speaker channel, switchable RCA phono/line and separate USB service and USB computer audio. Several copied DCB41 references mean those passages are not treated as DCB61-specific proof.
Wireless interspeaker signal, XLR and RCA analog, optical, coaxial and USB-B audio, Bluetooth and ConneX controls. An app does not establish a Wi-Fi music streamer. 222 W by 360 H by 268 D mm.

Manufacturer manual on authorized retailer host. Rear panel shows separate LINE IN and PHONO IN, plus auxiliary. HDMI requires stereo PCM. RF remote, dedicated input keys, eight remembered Bluetooth devices and manual Bluetooth handover. Both Connect sizes share this connection layout.
Original BR03 BT, not BR03 Connect or passive BR03. One RCA pair switches between phono and line. Auxiliary, optical, coaxial and Bluetooth, no HDMI or USB audio. RF remote and three-second Bluetooth disconnect. Powered speaker fixed right. 206 W by 360 H by 314 D mm.
