It's just something I saw advertised when browsing Barefaced bass guitar cabinets. As I am on a mobile phone it is a bit tricky to embed a link.
Anybody have an inkling as to what a Hybrid Resonator Enclosure is? They promise the same rate of roll off as sealed enclosures but with extra output. Anone own a barefaced bass cab? I am not sure whether they have hidden ports behind the area of grille that has no holes or whether they are using the entire front baffle as some sort of passive radiator, using some sort of rubber suspension sealing the edges of the baffle to the sidewalls and maybe some tuned springs inside the cab attached to both the front and back walls. However a passive radiator usually has a 24 dB roll off.

I wasnt sure whether this is better in subwoofers category seeing as it is talking about enclosure design.
They use ports, one on the side, looks like they have a port behind the grill in another enclosure. Might be dampening material in the port but I am just guessing.

I begin thinking about this concept for some time. The British have traditionally used thin wall cabinets but it wasn't until I read this article in Sound on Sound and the research study on which it's based that I began to understand what was going on (link at the bottom).
The study examined the popularity of the Yamaha NS10 in studios around the world. One of its characteristics was its thin wall construction. The article shows a waterfall analysis and it's clear that the cabinets quickly dissipate bass energy. The conclusion reached was that big heavy cabinets release low frequency energy more slowly which results in mostly undesirable effects but at least one fascinating one: that the delay in the release of low frequency sound could be attributed by the listener as the drummer and bass player being positioned behind vocals, lead guitar, keyboards, etc. In others words, some of the "depth" some report in the soundstage could be the result of a heavy speaker cabinet.
The professional sound reinforcement industry has moved to lightweight cabinets with scientific-derived bracing and it appears that the same is true for instrument speaker cabinets. I know that the next sub I build will try to incorporate these principals. The Yamaha NS10 Story |

Sounds like a load of... The speaker does not actually sound bad it is your material. And all the good recording made with 'substandard' speakers before them. When I listen to music I do not get the impression that the bass and bass drum is ten feet behind the rest if the instruments. And to think, there was a time when depth of field was a good thing. I'll pass.
Barefaced seems like a partnership between some serious speaker builders/thinkers and some brilliant promo-material writers. It's luscious prose and I have no idea what they are really doing.
And in any case: speakers are combinations of MANY factors. Even if you knew one "secret" you could not duplicate their product.
The vented alignments allow many intermediate tunings. 1970s E-V described "step-down" tunings which had an octave of low-slope before the final fall-off. It particularly reduced excursion in a useful range and with a modest box. My recollection is that the box was still larger (re: cone area) than the images on Barefaced, but memory dims.

...was based on, ummm, speculation, mostly.

That the NS10 doesn't actually produce much (cough!) low frequency energy (and doesn't rely on bass reflex or acoustimess to fake it) helps no end. It's a mid-bass to treble monitor ferchristake!
Now the comments on thermal compression explain why the few times I heard them (long, long time ago) I was underwhelmed (cough!) . But they were being compared with proper monitors based on Altec 416s. However proper monitors a) interact with the room b) were expensive and c) are too bloody heavy to cart around the globe.
However the MLSSA waterfall is pretty darn good for mass produced speaker, if not really world class*. That coupled with 90db/w (if real) means I need to give them another listening session
*See this image from a ESL for something really good (on Lynn's MLSSA pages )
