What customers say about "Key Specs"
Kicker KB6000 2-Way Full Range Indoor Outdoor Marine Speakers (Pair)
  • Great powerful speakers, bought 3 sets within 2 months, my parents patio, my deck then added to our boat the sound is awsome!!
  • Very nice speakers and they sound great. The more power the better they sound.
  • They are easy to mount and can handle way more power than I need as they see to have good efficiency.
  • They don't have a high rms rating and do not handle as much power as my old speakers, these do distort when I put the volume up all the way.
  • The music they produced sounded like it came from a pair of headphones dangling around my neck.
Polk Audio Atrium 4 Outdoor Speakers
  • Lots of sound for small speakers. Great quality too. Would definetly recommend to anyone. Great price. Easily powered by a 50W RMS amplifier.
  • 80 watts power handling plenty to spare in volume all you need is a decent receiver and you wont be disappointed
  • These speakers rock! Do not expect to get night club power, but the quality is great for normal level listening. the sound quality is amazing for such a small speakers. I love them!
  • Installed these on my boat with a Dual AMB600w 240 watt receiver and they can't handle the 60 watts going to them. Was pretty surprised considering their 80 watt rating.
  • Not as powerful as I had hoped for an outdoor space but quality is very good and they look great.

What customers say about "Size & Weight"
Kicker KB6000 2-Way Full Range Indoor Outdoor Marine Speakers (Pair)
  • Speakers sound good for there size. If you like to feel the bass then you will need to add a sub.
  • Perfect size for my application. I can't wait to get them installed on my boat to hear the quality of sound.
  • These speakers are a little weak on the bass side, but for their size they're GREAT.
  • These Kickers have a nice solid weight and feel to them.
  • They are made of fairly light steel, and seem a little flimsy for the speakers.
Polk Audio Atrium 4 Outdoor Speakers
  • They are the perfect size and weight for what I needed. They seem very solid and durable.
  • Great speaker for there size. Easy to mount. Overall very good deal.
  • These are a good size. I didn't want to spend the extra money on the bigger Atrium 5/6/8 and I haven't been disappointed. They fit great in the corners of my deck.
  • The sound quality is good and they have good weight, which typically indicates a quality speaker (big magnet).
  • Very easy to install and the construction appears sturdy

What customers say about "Audio"
Kicker KB6000 2-Way Full Range Indoor Outdoor Marine Speakers (Pair)
  • High and low frequency both sound great to my ear, to my wife's ear, and to my rock guitar playing son's ear. I am really happy with this purchase.
  • Much better sound frequency and bass compared to my old speakers. These are well worth the money.
  • The highs were nice and bright, maybe a little too bright, but I attribute that to not having the entire output balanced.
  • They fill the space with great sound and have excellent bass response for a speaker outdoors.
  • I only used them to add around the pool/beach area in the back yard to the barn stereo, works good for what I did but no low frequencies at all.
Polk Audio Atrium 4 Outdoor Speakers
  • Theses speakers reproduce high and low frequencies very nicely. Bass is solid and not boomy.
  • Mounting bracket allows for vertical or horizontal mounting with easy angle adjustment thanks to solid screw on end caps.
  • The volume is excellent, the frequency range is quiet good...and they have no problem pushing all the volume we need to the pool area.
  • Good low frequency. Flexible installation and adjustable positions as advertised.
  • While the sound from these Polk's is good, I was really expecting more from the lows and highs based on the price of these speakers. I had read that the frequency range of these isn't that great, so I should have been better prepared.
  • These speakers despite the name are quite unimpressive. they sound muddy, and do not seem to have a full range.... no real low frequency or high frequency response.
