Best Subwoofer for Unison Retrospective & Technics Speakers: Top Recommendations

Hello,

I need your help and professional advice. Which subwoofer to buy? I currently have. Unison Retrospective Edition "All-in-One" receiver with walnut amplifier, plus two Technics column loudspeakers, used from my brother. Advised me to buy a subwoofer for this? What do you recommend

Thank you for admitting me to the forum ?

From the instructions:

"The NUMAN brand Unison is also equipped with an effective amplifier providing output power to the connected columns 2 x 40 W RMS . "

Usually, in order for the system to be functional for every sound system, a bass channel with twice as much power as satellites is used. However, this is a very simplified selection scheme. A lot depends on the effectiveness of the used sets and the intended purpose of the whole sound system (size of the sound room, type of music, level of sound required). For home applications certainly a 60-150W subwoofer with an efficiency of over 100dB will suffice.
Examples of such products are:
Tonsil Subwoofer AKTIV 250 (Walnut), KLIPSCH R-10SW, KLIPSCH R-12SW, POLK AUDIO HTS SUB10, JAMO S810, JAMO J10, KODA SW-1000MKII, JBL SW 10.

Don't let the peak power, maximum power, PMPO give you off. The rated power is reliable RMS .

Thank you very much for such professional help ?
