    • High Performance 15-inch Subwoofer
Style: Subwoofer
Review Image by Rich Lawrence Rich Lawrence
The Klipsch SPL-150 delivers solid bass down to 18 Hz. The Power Switch has OFF, STANDBY, and OFF modes. The Phase switch has 0° and 180° positions. The LOW PASS control controls your crossover frequency. [The LFE setting allows your receiver to control your crossover frequency.] The GAIN control is the subwoofer power level (zero to 400 Watts). The only negative is that the instruction manual does not explain the above-listed controls. ... show more

    • Oh yeah! Feel the action!
Style: Subwoofer
This is a big... and I mean huge sub, it is a fantastic performer and great value. It has amazing responsiveness and snappy low low frequencies. It truly immerses you into the story and makes you feel the action as it shakes the entire house! If you are watching a drama, there is music with deep tones that lead the viewer and creates anticipation. With most subs you don’t perceive this, but with this monster sub, all that extra creativity that the producers put into the movie you can now appreciate. If you are watching Syfi or Action movies, HOLD-ON!! You are in for a ride because it’s like bringing the theater into your living room. I had a 15 inch Velodyne sub that I was replacing, it cost three times (yeah 3x) the Klipsch SPL-150 15 inch. Both are amazing products with small differences that are not perceivable. The Klipsch is a top performer with superior value!! Highly recommend for home theater! I used the wired connection not wireless. One thing to note is, when you calibrate your receiver, set the volume on the Klipsch sub to less than 50% (lower is ok as you can adjust this further later). Then turn up the sub volume on the receiver to your preferred level (or of your system self calibrates with a microphone, let it do it automatically). This will ensure that when you set the Klipsch sub to standby, it will auto sense the signal and turn it self on. If the volume on the receiver is to low then it may not notice (and may not auto turn on). You can play with this to make it ideal for your setup. Also if you want a little more base later, then just turn up the Klipsch to your preference. This gives you a ton of flexibility. Then sit back and feel the excitement! ... show more

    • Died after 3 years of light use.
Style: Subwoofer
Initially this was a great speaker with incredible bass output. However after after 3.5 years, the amplifier blew and the speaker just pulses now. Klipsch support is aware of this problem as several forum users have reported, but only offers a replacement amp for $300. Definitely not worth the money. ... show more

    • Perfection THUMP
Style: Subwoofer
Review Image by Upper Middle Class Upper Middle Class
If you have a high-end receiver and 7 high-end woofers and tweeters (bookshelf, surround etc.), then you should get two of these 15 inch Klipsch subwoofers. You can get the perfect balance of deep, clear, room shaking bass. Crank the subs' volume for music, turn them halfway for movies and games. The auto-off standby power setting is awesome. When I'm playing music my tv room is a night club. When I'm watching movies and something big falls on the ground I feel it like real life. You even get a cool 3DX theater type experience from some LFE effects because the subs make a pressure wave of air. 2 of these is pure audio perfection for any application! Especially if you separate the low bass (under 120 Hz) away from the other speakers and only let the lows pass to the subs (there is a low pass filter on the subs that works very well). If you are used to having powerful subs in the car, you can get the same low frequencies, THUMP and Boooom from these. Sacrifice nothing! And the price is nothing for this kind of ultra-high-end sound. Just make sure you tape down or put padding under anything that can rattle. ... show more

    • Very Musical Subwoofer - A Great Addition to My Cornwall IV's
Style: Subwoofer
When I bought this speaker it was a discontinued line from Klipsch. At one time this was their best subwoofer with an MSRP of $1349.00. So I was very happy to find new, old stock available at a nice discount. The seller, Adorama was very professional with my transaction as the speaker was damaged in shipping. I will not hesitate to purchase from Adorama in the future, I have confidence in their professionalism. I am in the market to extend and enhance the sub-frequencies of my Klipsch Heritage Cornwall IV series speakers. I'm interested for home stereo, turntable setup, not home theater. I read a couple of reviews from others who own Cornwall IV's. They added the SPL 150 sub and had very positive reviews. This subwoofer needs to be tuned to your room and speakers. There are plenty of online videos teaching how to do this. I am extremely happy with the SPL 150SW. My vinyl sounds very different, in a good way. I'm hearing low end and bass guitar, drums, etc., that I never heard before. This was a very good purchase for me and a very enjoyable listening experience. ... show more
