It delivers a strong performance when watching movies or just enjoying the beats of any music. You even get a pretty wide frequency range, offering you high quality low ends all while measuring to be a compact subwoofer with a seemingly simple but elegant design.\r\n\r\n[su_row]\r\n[su_column size="1\/2"][su_box title="Pros" box_color="#4DB227" radius="0"]\r\n[su_list icon="icon: check" icon_color="#4DB227"]\r\n\r\n \tWide frequency range\r\n \tDurable design\r\n \tTuning options are available\r\n\r\n[\/su_list][\/su_box][\/su_column]\r\n[su_column size="1\/2"][su_box title="Cons" box_color="#B2B9C3" radius="0"][su_list icon="icon: ban" icon_color="#B2B9C3"]\r\n\r\n \tPower output is pretty low for the price.\r\n\r\n[\/su_list][\/su_box][\/su_column]\r\n[\/su_row]\r\nPerformance\r\nThe amplifier comes with a 115W peak power output which although moderate, does fall behind with a continuous power output of 34.5W. However, paired with the frequency response range of 28-200Hz and the cone diaphragm of the speaker you still get a powerful low-end sound which is both clear and crisp with a good amount of resonance. Additionally, the bass reflex duct that suppresses any unwanted noise gives the subwoofer a better sound reproduction and therefore a bass that still sounds pretty powerful and deep despite not having that high a power output. Options like the Polk Audio PSW505 BIC America F12 come with a better, greater power output which gives you a much more powerful bass which is neither too boomy nor distorted, so if you have a bit more money to spare, these might be better options worth considering.\r\n\r\nMoreover, due to the Mica Reinforced Cellular (MRC) woofers you get a much better sound quality with deeper bass as the fiber on the woofer holds its shape rigidly even when playing audio, making no compromises on the sound quality. Any form of unwanted noise is also prevented further as the waves of noise are acoustically absorbed while damping the vibrations within the cabinet, thus giving you much more clear and noise-free audio quality from your active subwoofer.\r\n\r\nYou even get a number of additional features with the Sony SACS9 which makes it a much more convenient and easy to use home theater subwoofer. Firstly a tunable crossover lets you tighten up the low-end by varying the frequency response from 50Hz all the way up to 200Hz. And while there\u2019s a phase switch that allows you to make sure that the subwoofer is playing audio in phase with the speakers, you also get an automatic power saving feature that puts the subwoofer into a standby mode until an audio signal is present. Other than that you do get a volume control, making the audio reach as far as it can depending on how loud a sound you need. All in all, even though the Sony SACS9 doesn\u2019t offer as much customizability as some other subwoofers, the overall amazing sound quality of it makes tweaking the audio simply unnecessary.\r\nDesign\r\nMeasuring to be 11.5 x 16 x 13.5 Inches in size and weighing just 25lbs, the Sony SACS9 is much lighter than the Polk Audio PSW505 and much more compact too. This makes it easier to place in your room without taking up much space and with four foot pads it won\u2019t move around even at high volumes. The Sony SACS9 also comes with the traditional back facing ports which range from the standard RCA input to the speaker line outputs, thus making it easy to install and also pretty convenient to place with the 6.5Inch included phono cord.\r\n\r\nThe driver material in it is of woven fibre unlike the more standard paper or cloth in other woofers. Thus, you won\u2019t have to worry much about any form of wear or tear damage over time but the 2-year warranty might raise some brows. If by chance you come across any form of damage when you take off the plain vinyl foam-grill, which is made to be removable, do make sure to make an exchange or repair within the short 2-year warranty time.\r\nHowever, with that being a small compromise to make for such a great subwoofer, the design of it is fairly simple and not really it's selling point. You get a standard smart black finish over the build which along with the solid wood veneer gives you a quality design that won\u2019t affect your overall and bass sound due to changes in temperature or humidity.\r\nValue\r\nPriced at $158, the Sony SACS9 falls within the more affordable options of subwoofers. It offers a pretty deep bass and does live up to its price in terms of both design and functionality. Overall, it will serve you well for a standard desktop speaker system with a greater peak power output than the Polk Audio PSW10, but for a better music quality and more powerful bass, slightly higher priced products like the Polk Audio PSW505 or the BIC America F12 just seem like a better value.\r\nSony SACS9 Wrap Up\r\nWhile it may not have the most powerful bass nor a very aesthetic design, with the price range it comes at, the Sony SACS9 does provide you your money\u2019s worth. It gives you a pretty good home theater system but will fall back in terms of its power output and thus not reaching through to the end of the room, and so if you\u2019re okay with the amazing low-end sounds without the best bass quality, the Sony SACS9 with it\u2019s simple yet durable design might just be your go to. It\u2019s compact and convenient to use, but if you can reach a bit more deep into your pockets, options with a greater power output like the PSW505 are greatly worth considering.
