Doesn't this geometry suggest very strategic physical time alignment of woofer and widebander voice coils?

Gaul. For once, think widebander not wine. This freethinking country has given us Bernard Salabert of PHY; Supravox revived under Guy Le Cornec; and Fertin by Michel Fertin and Jacques Salette. In 2007, Michel's daughter Catherine or Katy spun off EMS for both ferrite and field-coil drivers. Today is about her LB5, a 4" mini widebander of 91.4dB, 2mm excursion and 50Hz resonant frequency…

Here with stock solid Beech phase plug. Optional gold-plated brass version available.

… and the B12 OB of 94dB, 9mm and 0.617Qts optimized for dipole use hence the OB suffix. Because raw drivers alone won't make music—most need a cab and crossover to work properly—we now move from France to Poland. There the Grodecki brothers Jacek and Andrzej operate Stereopolis and its brand Closer Acoustics. Their Ogy is just one letter shy of orgy; or adds one to the original gangster. Either way is juicy. It is this unfiltered monitor crafted from vertically stacked Ply whose serpentine undamped transmission line exits in a frontal smile. Unlike a constantly expanding rear horn, this back-wave guide narrows across its three switchbacks. Claimed good to ~50Hz solo, for more LF reach and heft the Full stack docks Ogy atop this curved H-frame dipole woofer. Et voilà, a different speaker concept uniquely executed. Its closest brothers from different mothers and fathers would probably be Voxativ's Hagen on the Alberich bass system; and for just a very compact widebander, a MonAcoustic SuperMon Mini or equivalent Lindemann Move Mini. Ogy omits the latters' auxiliary small AMT above 10-15kHz; and Hagen's whizzer. For that we should probably expect ~18kHz.

Given the rear wave's fourfold travel between the cab's front and rear walls, this line should be ~120cm long. 

As someone fond of well-vented headphones which eliminate room, multi-driver and crossover complications—talk about win/win squared—I'm by implication also fond of widebanders. For me, tapping their special qualities is not contingent on eliminating all filters. Go ahead, roll in an auxiliary tweeter above 8kHz purely in the overtone domain. My ears don't hear a problem. Ditto an active ~120Hz or lower high pass to hand off LF to a dedicated bass weapon that's optimized as bass pump rather than do-it-all. It prevents bass from even showing at the widebander's voice coil to reduce excursion-based distortion and thermal compression. Closer Acoustic roll in their woofer with a simple 125Hz/1st-order inductor to still run the monitor wide open¹. This puts naught between our amplifier outputs and LB5 voice coil but speaker cable. Purism pure. Having spotted no Full Ogy review, I wondered. Might team Closer see value in sending a set to Ireland? I had what I suspected were very appreciative ears. With a footprint of 13.2×30.6cm WxD and height of 31.2cm for a 6-litre volume, 8.6kg Ogy's closest size likeness might be Boenicke's W5. Meanwhile I knew nothing like its optional woofer stand. That adds 111.2cm to the profile then expands the footprint to 44×38.5cm WxD. Given 24 years of hard graft on this beat, eluding déjà-vu gets harder with each passing year. Full Ogy really did look like such an elusive outlier. Off my email went. The worst to happen was no response at all. In this information age, that's more common than you'd think. Zut alors or merveilleux?

¹ Maco Sound's Macarena which at this precise juncture of my narrative hit the scene first at the 2026 Toronto Audio Fest then Capitol Audio Fest combines its 4" widebander from Markaudio with an 8" woofer plus rear-firing passive radiator then executes the driver blend with a 600Hz 1st-order hi-low-pass filter for yet another way to have small widebander cake and eat bass, too.

Definitely magnifique is the option to have the outer surfaces finished in black or white synthetic stone i.e. DuPont's Corian. By adding amorphous high mass to the wood build, we'd expect some reduction in resonant cabinet behaviour. And of course surfaces done in hardwearing kitchen synthetics will wear well by not scratching or discolouring like waxed Ply can if not treated with care.

In this video we learn more about the genesis of the optional bass system. With 2×12" and 2×15" folded-dipole aka RiPol subwoofers of stacked Ply builds in my house—plus precision active analog crossovers with zero DSP latency to precede them with—I even had off-brand cosmetically congruent alternatives if Ogy were to sit on conventional stands. "We just returned from the Warsaw Audio Video Show so your timing was perfect. I'd be delighted to have Full Ogy reviewed on 6moons especially knowing your experience with filterless widebanders and open-baffle bass systems. We'll need to build a set specifically for your review as everything we had in stock has sold. We should be able to ship you in about three weeks." Full orgy inbound. Avec plaisir.
