Well, with 4 x 9” Woofers each speaker, which is about 2 x 12” woofers, I can see why they would need 120W in Full Range mode. Each tower is like a subwoofer.\n\nI think any tower with at least 2 x 10” woofers would need 100W+ power in full range, like a subwoofer would.\n\nBut most speakers don’t have dual 10” woofers, so most probably don’t even need more than 100W.\n\n\nThe Blade bass section is nothing like a competent subwoofer, having heard them with familiar material. There’s considerable cone area, but the system tuning, and I’m guessing the driver design, are not like a sub at all. I loved the Blades, but IMO they need subs for the 20-30Hz range. I also think Blades have a high low-distortion output capability, like the Salon2s, so you tend to listen louder than with more modest speakers, which gives people the impression of the speakers needing more power.
