Sigberg Audio: Building a "design" subwoofer that actually sounds good

Will there be models with bigger woofers? 15" 18" 21"

Nothing like that planned no. We have some plans (still on the drawing board) for larger subwoofers, but not with this form factor.

Our 10D subwoofer with dual 10" is roughly equivalent to a single 15" performance wise, with some penalty in the lowest frequencies due to its compact size.

@behappybevegan Feel free to share more about your use case / situation so I can understand better what you're looking for.

Thought I'd mention here that we've been in discussions with Trinnov beta testers around the topic of the Trinnov WaveForming technology, and our Inkognito subwoofers. We will explore this particular segment further in the coming months, and may have some demo setups has selected customers coming up.

In summary they find them to basically be a perfect match for this use case, having both decent power, high end sound reproduction and crucially the option of being installed on-wall (which is essentially a requirement to be able to place subwoofers according to the Trinnov placement guide).

Room coupling
A I guess not scientifically proved idea is that having the driver facing close to a wall or floor will reduce the room node problems for that specific plane. I don't have any other proof for this than measurements and listening tests and anecdotal evidence from testers (see below). But my impression is that the fact that both the driver is very close to the floor/wall, and the entire enclosure also is very shallow, somehow reduce issues with room nodes. I get less room interaction with this subwoofer than a regular sealed subwoofer at the same position. It also works very well half way up the wall (even less nodes triggered).

Hi! FWIW, it sounds like you’re observing the Allison Effect, or lack thereof with your designs. Way back when Josh Ricci ran the subwoofer show at Audioholics, he used to advocate for flipping subs to have the driver face the wall to mitigate those effects.

Some pictures from an installation of four(4) Inkognito 12" subwoofers in a pretty massive surround system (various B&W 800-series version for all channels on the floor, and an additional 9 speakers in the ceiling. He also already had four subwoofers, but added these as he's getting ready for the new Trinnov Waveforming technology. He may add an additional four Inkognitos down the road.

Not sure what this adds up to now, 9.8.9 or something.

For sure, but also priorities. Some have fancy houses, boats or cars, others pour all their money into their hobby.

Just ordered 4 additional Sigberg Audio Inkognito 12" subs. They are really that good
Aiming for the existing 4 centered around 3/4 of the room height, and the additional 4 centered around 1/4 of the room height. I will try to combine them with 2x Pardigm Persona Sub, but might end up selling the Paradigm Persona Subs.

Cross posting this from the SBS.1 thread here as well. Shared from a customer with two Inkognito subwoofers. In-room measurement and natural extension (no EQ to lift the bass). Only two EQ points below 100hz, no automatic correction.

Generation 2 has now been introduced (almost exactly four years after the original was launched):

Sigberg Audio Inkognito Generation 2

The original Inkognito subwoofer launched in 2020, and has received awesome feedback from both customers and reviewers! When it ain't broke you don't fix it, so the improvements are mostly practical in nature. Below is the complete list of enhancements in the second generation compared to the...

We measure every single subwoofer we build, and store the measurement with reference to the serial number of the subwoofer. In the measurements below you see the measurements of all three presets of two different subwoofers, also giving an indication of the consistency of response for each individual unit.

Note that these control measurements aren't done in a perfect anechoic chamber, so the peak at 45hz and subsequent dip at 50hz is room induced.
