Polk Audio RM705 5.1 Speaker package * Affordable Speaker options

If you're searching for a cheap 5.1 compact speaker system easily installed and powered?  This Polk Audio RM705 5.1 Speaker package might be ideal.

Polk Audio RM 705 is  a High performance 6-piece subwoofer/satellite 5.1 Surround Sound System
While most systems require you to buy their speakers separately, the Polk Audio RM705 provides users with 4 RM7 Satellite speakers, 1 RM7C Center Channel, and a powered subwoofer. The fronts and surrounds measure 6-1/8 x 3-4/5 x 3-3/4 inch and are composed of one 2-1/2 inch Midrange, a 1/2 inch tweeter and a dynamic balance composite cone driver. The center speaker measures 3-4/5 x 9-7/16 x 3-3/4 inch and provides a 2-1/2 inch midrange, a 1/2 inch tweeter and a dynamic balance composite cone driver. The subwoofer is an 8 inch with a dynamic balance composite cone driver and measures 13-7/8 x 12-1/2 x 12-1/2 inch . The speakers provide an overall frequency response between 40 Hz and 22 kHz with a nominal impedance of 8 ohms. The recommended amplifier for this setup should provide a power per channel that ranges between 20 and 100 watts.

Before I continue, you must understand.  Satellite speakers with these sized woofers cannot compete with full size bookshelves and towers.  However, the engineering and quality of these Polk Audio speakers will out-perform most home theater in a box speakers.

While most speakers are square, those in the Polk Audio RM705 setup are designed using a unique Reuleaux Triangular Polygon shape. This design was meant for more than just looks. This shape is quite strong and provides a higher level of acoustic quality which is designed to minimize resonances and standing waves inside the speaker. This helps to eliminate the muddiness that its similarly sized competitors can provide.

These speakers size and weight also give them a nice advantage.  Along with the mounting options pitched by Polk Audio as follows:

Put them on the TV stand. Put the Center Channel Speaker right on the TV. Put them on stands next to the TV (use Polk Audio's own custom-designed SA Stands, made to compliment the look of the RM speakers). Hang the speakers on the walls. Use articulating brackets to aim them perfectly. RM Series speakers weigh just 3lbs, so you can put them virtually anywhere and move them easily. But don't be fooled: high-tech lightweight composite materials allow Polk Audio to engineer in the high performance you expect, without the high weight.

 In the end of the day, these are ideal for someone who is looking for bang for your buck and doesn't or cannot deal with big speakers or placement.  These speakers are compact, sound good and clear, and with the 50w powered sub having adjustable phase, this will do everything you need it to.
