XXLS400 FF
Paired with Rotel RA-1592 and Fyne Audio F501 in 23sq m living room, not adapted. I am satisfied with this magic box - it is adding the base tones to the speakers, not overwhelming them. Plenty of adjust so I can put any level of loudness I prefer. What is even better I find the soundstage is altered for better when sun is active. For me a simple winner. Recommended.

Astounding control and depth of bass
I replaced an aging REL Strata with this 400w forward facing driver sub woofer and connected both LFE AND left/right high level input from the amp with supplied lead. The depth and effortless performance compared to the REL Strata is worlds apart. It makes the sound more even than the REL without the slightest inkling of strain. As an avid filmbuff, I'd highly recommend this sub. Used in a room approx 5x4m maybe slightly bigger. Also great support and advice from the company made the correct choice easy. Quality product from a caring company at a bargain price. What's not to like!

Great coffee table
My 1st active sub, replaced 20yr old kenwood series 21 passive. With new av, wow what a difference. Keeping my old kenwood speakers this just blends in great. Shook the room so turned down to keep 'the boss' happy, she didn't believe my 'plug in coffee table' story. Messed about with the settings for a few days to get levels about right, but until properly worn in...Oh and it fills our 4x4 mtr room just right, definitely not boomy, and very low bass played in movies. but at just over a quarter volume has got plenty of room for extra. Great with 5.1 and 2.1 for music. Worth the money
