Frequently Asked Questions - Octavox 703 MKII Auna

What is the power of the Octavox 703 MKII speaker?

The nominal RMS power is 100 W and the maximum power is 150 W.

Which amplifier should I use with the Octavox 703 MKII?

We recommend an amplifier with an output power of 150 W at 4 ohms. An amplifier that is too weak may damage the speaker at high volume.

Can I connect the speaker directly to my TV?

No, the speaker is passive and requires an external amplifier. Connect it to a home cinema or hi-fi amplifier.

What type of cable should I use to connect the speaker?

Use a speaker cable with a cross-section of at least 1.5 mm². A length of less than 5 m is recommended for optimal sound quality.

Can I mount the Octavox 703 MKII on a wall?

Yes, you can fix it to the wall using sturdy screws and wall plugs. Ensure the mount is suitable for its weight of 5.8 kg.

What is the impedance of the speaker?

The impedance is 4 ohms. Most hi-fi amplifiers support this load without issue.

How do I clean the speaker?

Disconnect the amplifier before cleaning. Use a soft, dry cloth. Never use liquid or abrasive products.

Can I use the Octavox 703 as a front speaker?

Although designed as a center speaker, it can be used as a universal mono speaker or as a front speaker in a small system. For stereo listening, two speakers would be needed.

What should I do if the sound is distorted?

Reduce the amplifier volume. Distortion indicates that the amplifier is too weak or the volume is too high. Do not increase the volume to compensate.

Is the speaker supplied with a cable?

The manual does not mention an included cable. Plan to purchase a suitable speaker cable (1.5 mm² minimum).

TECHNICAL DATA

Octavox 701 MKII

The Octavox 701 is a powerful floor-standing speaker and is perfect for HiFi and home cinema systems in rooms up to 50 m². We recommend free-standing installation with a distance of at least 70 cm from all walls. To enjoy the full dynamics of these speakers, we recommend a high-quality and powerful integrated amplifier, especially for the 701, according to the power recommendation at the end of this manual.

RMS output power 120 W / 200 W
Resistance 4 Ω
Dimensions without feet (W x D x H) 21.5 x 33.7 x 102.8 cm
Weight 21.4 kg

Octavox 702 MKII

The Octavox 702 can supply rooms up to 25 m ² with the entire frequency spectrum. For larger rooms and high listening volumes, we recommend the use of a subwoofer. Place the speaker on a stand, sturdy table or shelf, leaving about 30 cm to all sides to avoid excessive bass response. Please also note the power recommendation for amplifiers at the end of this manual. If you use the Octavox as a rear speaker, 30 watts per channel at 4 ohms is already sufficient.

RMS output power 60 W / 100 W
Resistance 4 Ω
Dimensions without feet (W x D x H) 21.5	x 24.7 x 33.5 cm
Weight 2 x 6.3 kg

Octavox 703

The Octavox 703 is a centre speaker for home cinema systems and multi-channel music enjoyment. It offers particularly clear and nuanced speech reproduction and a surprisingly full sound and can therefore also be used as a universal mono speaker. Place the speaker on a shelf underneath or in front of your TV or hang it on the wall with solid screws and plugs.

RMS output power 100 W / 150 W
Resistance 4 Ω
Dimensions without feet (W x D x H) 42.0 x 16.6 x 17.0 cm
Weight 5.8 kg

SUITABLE AMPLIFIERS

All speakers are typical 4 ohm speakers that harmonise with any HiFi amplifier without damaging it. We recommend an amplifier with an output power according to the table below; in case of doubt, the value may also be slightly exceeded. Please note: When listening at high volumes, it is more likely to damage a speaker with an amplifier that is too low in power than with a device that "has too much power". Octavox speakers can actually play music louder than many other HiFi speakers. If you still hear distortion, reduce the volume slightly.

Model Amplifier output power
Octavox 701 200 W
Octavox 702 100 W
Octavox 703 150 W

Connection 701 MKII

We recommend that you use speaker cable with a diameter of at least 2.5 mm ² for the Octavox 701. The shorter the cable, the better the sound. Cables up to about 5 m in length are absolutely safe to use. For a conventional connection without bi-wiring, please connect the upper and lower connection pairs with the supplied bridges as shown in the illustration. Then connect one end of your speaker cable to the two lower terminals of your speaker. Now, when connecting the other end to the amplifier, be sure to connect the PLUS terminal (usually RED) of the amplifier to the PLUS terminal of the Octavox connection panel - and MINUS (usually BLACK) to the MINUS.

Incorrect connections on individual speakers will not damage the amplifier or speakers, but the sound will seem "diffuse" and poor in low bass. Therefore, if you are dissatisfied with the sound characteristics after connecting, first check all connections!

701 MKII - Bi-Wiring (Double Wiring)

Separate speaker cables for the high/mid range and the bass range can further improve the sound of the Octavox 701. If your amplifier has 2 pairs of PLUS and MINUS connectors per stereo channel that can be operated simultaneously, please connect your Octavox 701 as shown in the illustration.

Connection 702 MKII & 703 MKII

We recommend that you use speaker cable with a diameter of at least 1.5 mm ² for the Octavox 702 and 703. The shorter the cable, the better the sound. Cables up to about 5 m in length are absolutely safe to use.

Please first connect one end of your cable to the two terminals on your speaker. Then when you connect the other end to the amplifier, please make sure to connect the PLUS terminal (usually RED) of the amplifier to the POSITIVE terminal of the Octavox connection panel - and NEGATIVE (usually BLACK) to NEGATIVE.

Incorrect connections on individual speakers will not damage your amplifier or your speakers, but the sound will seem "diffuse" and lack in bass at the same time. Therefore, if you are dissatisfied with the sound characteristics after connecting, first check all connections!
