No. There are no accessory or additional speakers that can be connected to the Solo 5 soundbar. The Solo 5 soundbar is a stand-alone unit.

Yes, if you hook them through an amplifier. We use them exclusively with our computer through amplifier. They sound great.

All speakers are compatible with a computer. All speakers require some kind of amplifier. Bose 201 speakers do not have an internal amplifier. You wouldn't connect Bose 201 speakers directly to your computer, you would connect an external amplifier to your computer and connect the Bose 201 speakers to the amplifier. One Bose 201 speaker is probably larger than your computer, and you need two speakers for stereo. A decent amplifier is probably larger than your computer. If you have the space for the amplifier and the two speakers, there is nothing that would stop you from using Bose 201 speakers for a computer. But, for a computer, you would probably prefer small speakers with an internal amplifier. I prefer headphones. Good around-the-ear headphones have better bass and overall sound quality than tiny computer speakers, are smaller than speakers, and don't require a power connection for an internal amplifier.

In order for these speakers to connect to a computer, you would first need to have a separate amplifier or receiver to power the speakers. Then you could connect your computer into this receiver or amplifier using the audio output connection from your computer. One method to make this connection would be to plug a 3.5mm stereo male connector into the headphone output of your computer and then the other end of the cable would be a dual male RCA connector that can be plugged into an available input on the back of the receiver or amplifier.

Thank you for the question!

These are passive speakers that must be connected to a receiver or amplifier. This can be a Bose product, or third-party. Be sure that the amplifier/receiver is rated 10-120 W per channel, 8 ohms.

Hello!
The 201 and 301 speakers are designed to work with a variety of stereo receivers and amplifiers as either front or rear channel speakers. Whilst we don't know exactly what subwoofer you're referring to here, as long as this is connected to your receiver/amplifier this should correctly act as the bass module in this system. The bass should be full and natural from the speakers themselves, but are not aimed at being the sole source of bass in a setup.
If you have further questions about this system, please get back to us so we can assist further!

Hi SamB, please contact us for further information. The UB-20 series 2 are not designed for the 201 speakers.
