The FV25HP has more mid-bass output, as I would have expected from its more sensitive drivers. It also has more infrasonic output below 16Hz since its tuned deeper. In general, the M215 does surpass it in deep bass at 40Hz and below. The M215 also has lower distortion at high output levels, but the distortion of either one is too low to matter. Click to expand... Without measurements, how can you tell that the M215 has lower distortion levels?

You can use the THX 15" Ultra measurements. All the M-215 is that x2. It's easy to extrapolate with that particular sub. Reactions: Hetfield and Danzilla31

I find the group delay measurements especially interesting. The Monolith shows superior group delay despite Rhythmik's much vaunted servo tech. Not that the FV25 is bad. It's more than acceptable. Inaudible for human hearing, but the Mono THX 15" is still just a little bit better through the deepest frequencies, staying below 1 cycle for the entire operating range.

I am not sure how Monolith does it, but they manage to keep group delay under a cycle at port tuning, which almost defies how ports work as I understand them. Port output should always lag at least one cycle behind woofer output. My guess is that they are using DSP to alter the phase of the input signal around port tuning to compensate for the port delay somehow. Obviously, this wouldn't be possible on an analog amplifier.

The much vaunted servo tech is to protect it from being over driven and not to control group delay. And since Rythmik keeps everything in the analog domain, there is no DSP control that can be used to lower it as Shady theorized for the Monolith. I also dont see any value driving the group delay further into inaudbility as long as it remains inaudible. Last edited: Mar 31, 2022 Reactions: panteragstk, Danzilla31 and Pogre

I always thought the servo tech helped reduce group delay too. It's been a while since I've read up on it. Reactions: panteragstk and 3db

The deep bass in my home office that has two smallish Genelec monitors and a smallish ported Genelec 10" subwoofer beats the HT in my living room using two SVS SB-3000 sealed subwoofers. Both systems are calibrated (Genelec GLM "vs" Audyssey XT32) but sometimes one just have to deal with the cards given i.e. possible placements of MLP and the rest. Below is an example of what I tested with.
