Klipsch R-101SW II vs Pioneer SW-8MK2
My review consists of a comparison of the two sub-woofers their features, overall performance and which unit I feel provides the best value. The Klipsch is equipped with a 10″ driver, it is a front firing unit and its cabinet is rear ported. The Pioneer is equipped with an 8″ driver, it is a down firing unit and its cabinet is ported in the front. The Klipsch produces a continuous maximum output of 150 watts while the Pioneer’s maximum output is 100 watts. Both units share similar control panels on the rear of their respective cabinets, which include volume, frequency and phase controls. In addition both have a three position toggle power switch. Both units also share two Line In inputs which allow them to be connected to an A/V Receiver utilizing an RCA type sub-woofer cable. The Pioneer also has a feature that the Klipsch does not, which is four Speaker Level inputs which is designed to be used on receivers which do not incorporate any RCA type subwoofer outputs. The power cord on the Klipsch is removable and plugs into the rear of the cabinet, the power cord on the Pioneer is permanently attached to the unit. The Pioneer units is considerable smaller than the Klipsch, as it measures W x H x D 12 1/4″ x 14 1/4″ x 12 1/4″ overall, this may be of importance if space is limited.
The Klipsch has a removable grill which provides one with the choice of leaving the grill off and displaying the 10 ” copper colored driver. The Pioneer weighs 20 pounds 4 oz and the Klipsch weighs 31 pounds. The frequency range of the Pioneer is 38Hz – 150Hz. The Klipsch unit is rated as High Resolution Audio and has a all digital amplifier. Both Units have a led status indicator on the front of their respective cabinets, which works in conjunction with the auto on/off power switch of each unit. Performance wise, I found that the Klipsch was definitely capable of producing more bass and its phase control provided a somewhat smoother introduction and mix of its bass audio than the Pioneer. However, the room that my 7:1 home theater system is set up in has a carpeted floor and the carpet and padding absorbs rather than reflect the bass audio from the down firing driver. That said the Pioneer would perform better on a hardwood or tile floor and the Klipsch functions well on any type of floor. I personally felt that the overall cabinet finish and the application of its wood grain vinyl was superior to that of the Klipsch. The Klipsch currently has a suggested Retail Price of $499.00 and the Pioneer had a retail price of under $200, the Pioneer was designed by Andrew Jones, it is five years old, looks and operates like new. The Klipsch has a five year warranty and time will tell if it lasts the test of time. I would recommend that if you decide to purchase a Klipsch that you wait until the unit is goes on SALE @ Best Buy! The attached photos are of the Pioneer unit for comparison purposes.

I recently added the Klipsch Reference Series 10″ Powered Subwoofer to my home audio setup, and it has completely transformed my listening experience! The black finish is sleek and fits perfectly with my other equipment, but it’s the sound that really stands out.
The 150 watts of power delivers deep, rich bass that you can really feel, making movies and music come to life. Whether I’m watching action-packed films or enjoying my favorite tracks, the subwoofer adds a whole new dimension to the audio. It handles low frequencies beautifully without distortion, even at higher volumes.
Setup was a breeze, thanks to the straightforward connections. I appreciated the adjustable gain and crossover settings, which let me customize the sound to fit my room perfectly. The compact design is also a plus—it doesn’t take up too much space while still delivering powerful performance.
Overall, the Klipsch Reference Series 10″ Powered Subwoofer is an excellent addition for anyone looking to enhance their audio experience. It offers fantastic sound quality and great value for the price. Highly recommended!
