What customers say about "Size & Weight"
Polk Audio TSi300 Floorstanding Speaker (Single, Cherry)
  • Very sharp and contemporary design, with awsome sound. Tall but thin. Works very well in a livng room with too much furniture.
  • They are not very heavy. They give a clear sound on high frequencies.
  • Given the sound, size and cost I think it is a great value and would do it again.
  • Great size, not too ungainly in the living room, yet more than adequate bass presence.
  • Considering the compact size of the speakers, they provide suprisingly good sound imaging, projecting a wider sound-field than you'd initially expect,
Polk Audio TSi400 Floorstanding Speaker (Single, Black)
  • The cabinet finish is flawless - typical of Polk. Give them a try - I think you'll be impressed with how good a modestly priced speaker can sound.
  • They are extremely beautiful to look at. They have shiny, black plastic tops that have a mirror-like finish. As a piece of furniture, they are first-class.
  • The shape of these speakers is a rectangular prism measuring seven inches wide, fourteen deep and standing thirty-eight and three-quarters tall. They come in two colors, black and cherry. These speakers are very handsome with a black textured surface on the sides with a glassy solid top.
  • The room where they are installed is approximately 15 by 20 feet with several pieces of upholstered furniture.. My first impression when listening to these speakers was that there was more music.
  • Excellent projection. Very attractive and we didn't have to cut a hole in the wall. Nice size too. Don't need to worry about tipping (good weight). Would definitely recommend.

What customers say about "Audio"
Polk Audio TSi300 Floorstanding Speaker (Single, Cherry)
  • Really nice smooth sounding speakers that are easy on the ears.
  • Highs are very smooth as to be expected from a soft dome tweeter. No harsh ear bleeding screaming here.
  • Glass shattering in movies might be a bit subdued but musically they perform quite well.
  • They give out a nice tight sound from the drums to the vocals.
  • Great sound for the price and size. Full and warm through the mids, clean and balanced in the highs without too much brightness, and lows that transitions smoothly.
Polk Audio TSi400 Floorstanding Speaker (Single, Black)
  • A lot of speaker for the dollar. I like the natural sound - no heavy bass or excessively brilliant highs.
  • The Polk TSi400s are very efficient - this is especially important for those of us with relatively low powered vacuum tube amplifiers. A 30W amplifier will do nicely with these speakers in an average sized room.
  • I've driven them with an older Harman Kardon amp and a newer SMSL amp without any problems.
  • The TSi400 have a one inch tweeter and three five and one-quarter inch mid range/woofers. To my ear, the sound produced was clear and crisp at all ranges.
  • One common complaint of tower speakers is that they require a high power level. The A-V receiver has a rating of 95 watts per channel. This was adequate to create a comfortable listening level using only 20 to 30 percent of power.
  • The overall sound is dead. It is too dry and has no resonance.

What customers say about "Features"
Polk Audio TSi300 Floorstanding Speaker (Single, Cherry)
  • The speakers look very nice (cherry finish) are well made not cheap looking at all and sound fantastic!!
  • The cabinet is quite nice, the veneer is lovely and it is nicely selected and applied. These don't look cheap or sound cheap.
  • The crossover is well designed and is mounted to the back side of the speaker terminals which is the case for most speaker designs.
  • I'll just say if your looking for a beautiful to look at as well to listen to speaker pkg you can't go wrong here.
  • Nice looking tower speakers for the living room. Love the glossy finish on top.
Polk Audio TSi400 Floorstanding Speaker (Single, Black)
  • No grit my teeth steely overtones common to many much more expensive speakers. Very clear voices for choral music too. Just enough bass to matter. - these are not speakers for heavy metal blastophiles.
  • These speakers are perfect for the baroque period of classical music I enjoy. Violins and other bowed string instruments sound like they should (with a good quality recording).
  • I bought a pair of these in late 2013 (when they were priced nearly twice what they are now), and since then, I have been nothing but impressed with them. The sound is awesome, from low-level, morning jazz sounds to full-on cranked 70's rock, and they look great in my living room.
  • The Polk Audio TSi400 is an excellent tower speaker at a very reasonable price which can be used without depending on a sub-woofer. They fit comfortably into small and medium sized rooms and provide a quality listening experience.
  • I'm using these as part of a 5.1 surround system and also for regular music listening. Love them, would buy again.
  • The speakers do not have a bass port. Whether this has any impact on the bass sound they produce is unknown.
