Drivers

One of the fundamental differences between these two speakers is that W280-IDC is a 3-way design whereas the R-5800-W II is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

Driver Setup 3-way 2-way
Tweeter 1-inch 1-inch
Midrange 1 x 4-inch -
Woofer 1 x 8-inch 1 x 8-inch

W280-IDC features a 1" Hard-Dome Tweeter , a 4" Midrange and 1 x 8" C-CAM Woofer . On the other hand, the R-5800-W II features a 1" Horn-loaded dome Tweeter and 1 x 8" Cerametallic Woofer .

Frequency Response

W280-IDC has a frequency range of 45-30kHz whereas R-5800-W II has a frequency range of 40-23kHz. With a minimum frequency of 40Hz, the R-5800-W II can go significantly deeper on the low side and provide stronger bass compared to the W280-IDC's min frequency of 45Hz.

Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the In-wall class in our database.

Power Range

Power range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.

W280-IDC can handle a max power of 120 watts RMS from the amp the whereas R-5800-W II has a max power handling value of 50 watts RMS, 70 watts less than the W280-IDC.

Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters such as Impedance, sensitivity and system efficiencies.

Input Type and Bi-Amping / Bi-Wiring

W280-IDC features Spring post type posts and R-5800-W II has a Spring post type posts. None of these speakers feature bi-amping/bi-wiring.
