KEF

CorporateAV.ae is a supplier of genuine KEF products in the UAE, and this collection lists 81 of them. They are 33 Ci in-ceiling and in-wall speakers, 25 passive hi-fi and home cinema speakers, 7 wireless and active speakers, 12 subwoofers and 4 amplifier and installation accessories. The range includes the Q, R, Reference, Blade, LS50 Meta, T series and Ventura speakers, the LSX II and LS50 Wireless II systems and the XIO soundbar.

The Ci, Q, R, Reference, Blade, LS50 Meta, T series and Ventura speakers are passive, so they need an external amplifier. KEF lists the recommended amplifier power on each product page, for example 15 to 200 W for the KEF Q7 Meta at 4 Ω and 10 to 125 W for the KEF Ventura 6 at 6 Ω. Match the amplifier channel to the speaker impedance and the power range before ordering.

The KEF LSX II, LS50 Wireless II, LS60 Wireless, Coda W and LS LUXE speakers have amplifiers built in, as do the KEF XIO soundbar and the KEF Muo portable speaker. They need only a source and power. For example, KEF lists 70 W (LF) and 30 W (HF) Class D amplification per speaker for the LSX II and Coda W, and 280 W (LF) and 100 W (HF) for the LS50 Wireless II.

This collection lists 12 KEF subwoofers. The Kube 8, 10, 12 and 15 MIE, KC92, K62 Twin, K62 Dual and Reference 8b are powered subwoofers with built-in amplifiers, for example 300 W RMS in the Kube 10 and 1000 W RMS in the KC92. The Ci200QSB-THX, Ci200TRB, Ci250RRB-THX and Ci3160RLB-THX are built into the wall or ceiling and use the KEF KASA500 amplifier in active mode.

The cut-out depends on the model, and KEF publishes it on each product page. The KEF Ci100QS needs 112 × 112 mm, the KEF Ci130QS needs 158 × 158 mm and the KEF Ci200QS needs 238 × 238 mm. The KEF Ci160TS is only 41 mm deep and needs a 194 × 194 mm cut-out. Check the ceiling thickness range and the mounting depth against the void before ordering.

In-ceiling models such as the KEF Ci200QS are round or square and sit flush in the ceiling, while in-wall models such as the KEF Ci200QL are rectangular and mount in a wall. The in-wall cut-out is larger, 334 × 238 mm for the Ci200QL and KEF lists 35 Hz for the Ci200QL against 45 Hz for the Ci200QS. Both are passive speakers rated at 8 Ω, so each needs an external amplifier channel that suits that load.

KEF lists THX certification for the Ci models with THX in the name. The Ci160RR-THX, Ci250RRm-THX, Ci3160REFM-THX, Ci3160RLM-THX and Ci5160RLM-THX are THX Certified Ultra, the Ci3120QLM-THX is THX Certified Select and the Ci5160REFM-THX is THX Certified Dominus. The Ci250RRB-THX in-ceiling subwoofer is also THX Certified Ultra. Ultra covers the 6.5 in Ci160RR-THX, the 10 in Ci250RRm-THX and the in-wall Meta and Reference models, and each product page shows the level as KEF lists it.

The KEF Ci160TS is a thin in-ceiling speaker, 41 mm deep with a 4.5 in driver and a 194 × 194 mm cut-out. The KEF Ci160TR is 40 mm deep with a round 196 mm cut-out, and the KEF Ci200TRB thin subwoofer is 63 mm deep. KEF publishes the mounting depth on each product page, so compare it with the ceiling void before ordering.

Yes, the KEF KW1 TX/RX kit links the KC62, KC92 and Kube subwoofers wirelessly. KEF lists 5.2 GHz and 5.8 GHz radio, 24 bit and 48 kHz sampling, latency under 17 ms and a link distance of up to 100 ft in line of sight. KEF lists an expansion port for the KW1 on the Kube and KC92 subwoofers, and the kit is sold separately.

The KEF Ventura 6 is a 6.5 in all-weather outdoor speaker with a frequency response of 54 Hz to 20 kHz (±6 dB) at 6 Ω, and it needs an amplifier. The KEF Muo is a portable Bluetooth speaker with an IP67 dust and water rating, an operating temperature of -20°C to 45°C and up to 24 hours of battery playtime at moderate volume. Check the product page for the exact ratings.
