Open baffle speakers

@coltrane1 Thank you for your kind comment. There are several videos of the system on my channel. Regarding the subwoofer topic of this thread, I would recommend watching the video featuring Maggie Rogers "Alaska" - wonderful bass texture on that track.

@mark200mph You were writing about DSP crossovers, and their beneficial capabilities. While some will say DSP flattens the sound (Danny Richie being one), once you have the ability to adjust crossovers, parametric EQ, individual gain and delay on the fly while listening... its hard to imagine not having the capability.  When purchasing pre-manufactured speakers with passive crossovers, you're putting a lot of trust in the mfg that they voiced them to your liking, and that they will do what you want in every room, at all volume levels and across every genre of music you may enjoy. With DSP, you can save presets, and change them at will. I can't imagine a speaker a speaker so perfect that I wouldn't want to adjust it... maybe if it came with its own listening room, had a fixed volume and only played one song? Again, not bashing passive crossover box speakers - my HT system is littered with them. But for critical 2-ch listening, best be able to adjust.

@mwatsme  I still dont understand why the speaker company dont making  a Subs wth open back? Just close box or ported, So stupid ?

40 years in this hobby and owned all styles of designs in that time. New designs of open baffle speakers are like having a Magiee or Quad Electrostatic but with the full bottom end, extended highs, and dynamics on steroids. They work great in all rooms, and like all speakers sound best 2-3 feet from the front wall. No different than box speakers.

So much in the audio is talking about how things were in the past, from Class D amps to digital and DIY OB speakers.

This is 2024 new time and era of new designs that have had years to mature and form.  Open baffles speakers bring the music "live" into the room. Besides my Quad ESL's OB speakers on well-produced recordings sound like they are playing in your room, yes they sound different than box speakers as do the panel and electrostatic speakers and that is not a bad thing music-wise. 

@phillyb, Great take! I could not agree more. But first you’ve got to have an open mind. I’ve owned Electrostats for over 40 years. For years CLSiiz’s were my speakers of choice. I relished in their midrange which I believed was not matched by box speakers. We all listen differently, and prefer different components, so why should loudspeakers be any different? But 15 years ago I met an audiophile who was a professional woodworker. He built his own speakers, using solid woods and no mdf. He began building OB speakers using bass speakers specifically made for OB’s. I was floored by their performance to reproduce authentic sounding bass, which was as natural as I’d ever heard. I purchased several pairs, all while keeping my electrostatic speakers. Enjoy whatever speakers you choose. But to denigrate someone else’s choices, especially when you’ve not heard them, seems a bit harsh and illogical. We each have our biases. Allow others to enjoy and live with their choices. After all, audio is about freedom of choice. 

I heard those OB speakers a year ago or so and they were really good and very small. There are two planar tweeters mounted angled on each side and a midrange. Four 8-inch base drivers (might be sealed, hard to see and I don't remember).
