Product Description

Amazon.com Product Description

The SRS-RF90R wireless speaker is an optional speaker for the SRS-RF90RK. This one-box speaker system provides a fifty-seven millimeter woofer and two, thirty millimeter tweeters. With four watts of output power, this system provides ample sound in a small package. The neodymium magnets in the tweeter provide high magnetic energy per ounce and produce a crisp, clear sound. Meanwhile, the sigma type magnet in the woofer produces deep bass. The built-in Mega Bass system further encourages a solid bass level.

This wireless system uses 900MHz RF technology to transmit the music from sound source to speaker. With a 150 foot range, you should not have any problem in using this system properly. The built-in receiver in the SRS-RF90R has three channels to help with interference. The speaker will automatically choose which channel has the best reception, making the listener's job easy. This receiver is compatible with the transmitters on the MDR-RF915RK, the RF815RK and the RF945RK.

You have two options for powering this speaker system. For unlimited power supply, use the AC adaptor. Or, use the rechargeable battery system for complete wireless listening. The built-in recharger will charge the batteries in twenty hours. A fully-charged battery will yield 3.5 hours of use. This speaker is portable, lightweight and stylish. Sony has even included a blue illumination color should you choose to highlight the speaker's high-tech look.

What's in the Box
Sony SRS-RF90R speaker, user's manual and a ninety day warranty.

2.0 out of 5 stars THIS IS ONLY AN EXTRA SPEAKER, November 22, 2003

Be careful when you order this item. Even though the picture above shows the speaker with the transmitter, this product is just the speaker. If you don't already have a transmitter, you want to get item number SRSRF90RK.

4.0 out of 5 stars Nice item; works great with Apple ipods, March 12, 2004

Not sure why everyone else received the speaker without the transmitter. Mine came with it and overall sounds pretty good in my bedroom. No there's not a whole lot of bass, but visually it looks pretty nice especially at night with the cool illuminating blue light. For my purposes, I hooked this baby up to my new mini ipod and it works fantastic!

1.0 out of 5 stars NOT a happy customer, December 25, 2003

I bought this as a gift for my parents and just found out [Dec. 25th] they need to also purchase a transmitter to get the darn thing to even work. The picture shows the transmitter- there is NO mention of requiring this piece as well. This information is necessary in order for someone to make an educated decision on whether or not to buy. What a slippery marketing tactic.
