Accuton speakers 1970
It would be great to obtain feedback from anyone who has made these speakers and their thoughts on the overall results. Thank you considerably, Kris. I think Jon did a design with a similar cabinet for a lot less money. He'll probably come by this thread and post it.

The Shelf Speaker
Not a bad speaker at all in either design. In , I had my first taste of Thiel CS 2. In , I auditioned the CS 2. In each brand the passive radiator Thiel and acoustic coupler Vandy really adds flavor to the musical presentation, IMO. I feel Thiel has the better energy.
It seems to me that if one had a cabinet big enough for the size of many of the passive radiators used, why not just add a cross-over and add another woofer? Or just use a larger woofer to start with? Sure there would be some added expense, but I'd much rather have a proper sealed box than any ported design, passive radiator or not. With DSP and digital EQ having made such strides recently, I wonder why someone has resurrected the eq'd sealed box designs like the earlier Thiel's up to the 3.
With updated DSP and EQ one could adjust the bass so that not only in anechoic chambers but one's actual room, the most troubling frequency range, the bass, could be optimized. LOG IN. Folks, What are your thoughts on Passive Radiators in speaker design?
I've had many different speakers and like many here, have heard countless varieties outside my home , from ported, to sealed, to passive radiator, to transmission line. In my experience by far the best bass has come from the Thiels I've owned - CS6, 3. The bass in these designs are punchy yet as tonally controlled, or more, than any other speaker design I've heard. So I figure the choice of a passive radiator must be involved somehow, and it makes me wonder why more speaker designers don't use this method.
It seems to give some of both worlds: extended bass, no port noise, tonally correct. And yet, it seems a relatively rare design choice for speaker manufacturers. Edit Delete. Everything is a trade-off in speaker design. If there was one "right" way, all speakers would share that design! Each designer weighs the trade-offs to optimize what they think and feel sounds best. Sealed boxes tend to give the best definition and resolution but at the expense of extension and ability to play loudly.
Ported designs, including Thiel's radiators give better extension but at the expense of low bass timing being a bit slow. One "good" source of info is the Audio Perfectionist Journal, archived on the Vandersteen website under Resources, Richard Hardesty memorial. In particular, I suggest Volume 3 for trade-offs of vented and sealed enclosures. I would add hot links but Audiogon's link feature does not work for me.
I've searched in vain for other speakers with as tight, tonally controlled bass as I hear from this passive radiator design. I agree that it is a "successful" trade-off and I am plenty happy with the bass performance of my CS2. But I think you need to directly compare sealed vs. Most designers have much more experience with this than me and, presumably, you.
In the case of Thiel, it could be instructive to compare the bass performance of the sealed box CS3. I have no idea what Thiel's rationale for the change was but, clearly, he thought the trade-off was worth it. The dearth of other models with passive radiators suggests other designers hear it differently. It is a sealed enclosure. I consider the passive radiator a special case of a vented design: 1 Sealed enclosures 2 Vented enclosures 2a Ported 2b Passive radiator Keep in mind I'm just a bozo typing opinions on a forum, not an expert!
Hey man…all bozos are welcome on THIS bus…Well designed passive radiators do fall into the "venting" category although you'd think they imply a sealed box, but the passive radiator is sort of the "unsealed" part part of the thing.
I own a discontinued Mackie HR sub that was designed for home use not the "drag it around to gigs" P. REL does well with their passive radiating little subs my 2 RELs don't have those, but work anyway , as do many others of course, and it's simply another flavor…personally I prefer raw drivers suspended from fishing wire 2 feet from my head, but that's just me.
A bozo. Wait just a minute, you may indeed be a bozo but not as big a bozo as me. I've only been at this umpteen years and I don't know vented from sealed I occupy the front seat on the bus! I only know of the below three factors. You might ask why anyone would choose to make a vented subwoofer.
There is one very good reason—high output. The one advantage that vented enclosure designs offer is a reduction in cone excursion at low frequencies.
Reduced cone excursion allows vented designs to play louder. A side benefit is that reduced excursion will also produce lower steady-state harmonic distortion measurements.
Alignment is unusual and bass is tightly controlled with little evidence that the enclosures are not sealed. So, Hardesty was a big fan of sealed enclosures and even bigger fan of Vandersteens yet he implied that the Thiel's passive radiator sounded not too different from that of a sealed enclosure.
In turn, this implies that Thiel's passive radiator is a "good" trade-off between sealed and ported enclosures. I have a pair of Golden Ear Triiton Reference speakers, each of which have four passive infrasonic radiators. Suffice it to say the bass is incredible, IMO. I used to own the original Sonus Faber Grand Piano which had a passive front radiator.
A small floorstander that was pretty easy to drive but always seemed a bit bass shy to me. Never really fell in love with it and sold it before to long. I know that adds nothing to the conversation and I am at the very back of the bus. Mainly seen in horn drivers, big woofers Klipsch comes to mind. Not very accurate that is why most don't use them. I am almost always impressed by speakers that make good use of passive radiators compared to the competion.
I picked up an 8"front firing Klipsch sub with two side firing passives recently. Was originally looking at much bigger bulkier subs but this little thing competes with the much bigger boys in every way. I vote for more passive radiators!
A passive radiator is expensive compared to a tube. It could be a reason why it is rarely used. With a passive radiator you don't have port noise, but it's not true that there aren't sound at mid frequency that go out from passive radiator. At mid frequency, passive radiator cone interacts with a woofer cone. If you use a low pass filter at low frequency you will not have any problems.
With a passive radiator or port you can choose damping of your system and you can get the same result in the listen experience I don't like passive radiator due to non linearity of the suspension. Speakers is a really complex non linear system, if we add another non linear component you can loose some performace.
I'm on the bus, too. My Vandersteen 2Cs are a 3-way, with an acoustic coupler on the back of the speaker. Are they considered acoustic suspension? Systems utilizing passive radiators ARE, "vented" systems. The Thiele-Small parameters and calculations, are identical for both. Sorry, forgot to ask is an acoustic coupler the same as a passive radiator?
The 2Ce and 3A use sealed enclosures I think the Treo has a downward firing port. From Tom Norton's 3A review in stereophile: A cutaway photo reveals four drivers and three separate sub-enclosures—the bottom of which is the largest, for the rear-facing 10" driver that Vandersteen refers to as an "Active Acoustic Coupler. Since the AAC is designed to cover primarily the range below 35Hz, I would be inclined to call it an integral subwoofer; but perhaps Vandersteen chose to give it another designation to distinguish it from the company's dedicated, outboard subwoofers.
I think the crossover is designed as a 3-way, so not sure how this thing works - and I ran 2Ce Sig IIs for 10 years! Maybe the filter for the woofer has a sub-network for the AAC?
Hi guys, Well, a lot great info, a few minor inaccuracy's Even the Richard Hardesty post is more opinion and not cast in stone. Yes, A passive radiator is more of a vented or ported design.
When we do a ported speaker, Lengthening the port lowers the frequency of air moving through the port so changes the frequency the woofer peaks at. There are many ported speakers out there that are great.
A passive radiator works similarly in that as you add mass to the radiator, it will like a port, change frequency where there is a peak or dip and by how much. Every driver does change spec as it is used over the years and fact is, a sealed box comes much closer in keeping its original sound as it wears and a ported box is the same.
Oddly enough in my own speakers at home right now, I have 3 pair built. A 10 inch 3 way in a sealed box, an 7 inch mtm in a ported box and a 12 inch 2 way big Heil amt in a passive radiator box. All 3 are flat, accurate and fast with the right equipment in front of them. In the technical section of his Rythmik Audio website, designer Peter Ding makes his case against passive radiators in subwoofers.
In the late s I had a pair of Koss passive radiator loudspeakers. The radiator thick plastic passive cone had a weight one could add to further dampen the radiator. I drove them with a Dynaco St Traded them for a dining room set and purchased Genesis old east coast sound passive radiator floor standing speakers.
The cabinets were real oak and the tweeter was a plastic thing in a rectangle faceplate.
Estelon XC standmount loudspeaker
Crossover is external and should not even be considered a preliminary design. It is repurposed from my NT10 design as a stand in while drivers are measured and Fi16 crossovers both passive and active are designed. DSP in JRiver music player software was used to correct the 8. This is the speaker yielding the results for the listening report I will post next. Attached Images Fi16v1 first listen. JPG Find More Posts by Norman Tracy.
8-9 inch Bass Speakers
I first heard a pair of Salk Sound speakers at the California Audio Show a number of years ago and I was impressed with the presentation. The Salk Sound website indicates that several of their models utilize transmission line designs, an approach that can give extended bass of high quality. I have an old pair of ESS Translinear speakers from the s also using a transmission line design, which I refurbished and still occasionally use. The best part of those ESS speakers is their Kef B woofers and the ability of those woofers to take advantage of the extended bass. The worst part is the speakers are very big and very heavy. They also sound dated when you compare them to more modern designs. Salk Sound owner and chief designer Jim Salk keeps its speakers affordable by selling them factory direct. The company offers a very large selection of speaker models.
Scan-Speak
To compliment them, I bought a pair of Bel Canto m monos. Those are good but subdue some treble energy which robs the speakers of a certain excitement. I spoke with Clayton Shaw of Spatial to learn whether he had particular success with any particular amplifier. He said he'd bought himself the LinnenberG Liszt, having been amazed by their sonic qualities.
Innovation In Studio Loudspeaker Technology
For me, trying to capture the essence of any audio component can only be done through musical description. But as I have said in this magazine many times, we listen to systems and not individual components, and the reviewing of anything requires some experience of the various audio alchemies involved. If we are to wring the best possible performance from audio equipment then, this demands paying attention to everything that contributes, including components and system infrastructure, adequate run-in, positioning, and of course patience — sometimes lots of patience. As if I needed reminding, these demands came home with a resounding crash when Kog Audio arrived in the distant past of November to deliver a pair of Estelon XC speakers and install them in my living room. I set my sights on one day securing a pair of high-end ceramic-driven loudspeakers: so the opportunity of a lengthy loan of the Estonian-made Estelons proved hard to resist.
Manufacturers
Monitors are better than they've ever been — but they're still the weakest link in most studios. We trace the technology from its roots in the s, and find out whether there's a DSP revolution on the way. Who'd have thought, 20 years ago, that in we'd be able to create complex music on a small handheld touchscreen device, share it instantly with somebody on the other side of the world and then call them — with video — from the same device to enthuse over just how cool we both are? It is truly extraordinary, and if I think back to when I first started making and recording music with friends back in the early '80s, what we have now would have fallen then into Arthur C Clarke's 'magic' category see Note 1. Can you tell where this is going? Despite the 'magic' we now take for granted, there's one piece of recording hardware that, in comparison to all the DAW, network, and plug-in malarkey, often looks as if it has spent the last 50 years standing still, never mind the last few years. I'm talking about monitor speakers, of course. In the context of extraordinary change elsewhere, doesn't it strike you as odd that the monitor that's still the one most often seen in commercial studios, the Yamaha NS10, was designed in — well before I first slipped an extra high-output chrome cassette tape into my Fostex multitracker?
What's wrong with this picture?
Unconventional to the bone, hand painted objects of art stand out of multitude of deja vu boxes with little of no refreshing rates. This is especially evident with some German cars where it takes generations to morph into something very different. Safe and sound, seems to work for the larger portion of faithful brand customers. Volya Audio Bouquet speakers strikes with completely different impact.
Scan Speak
Scan-Speak is the world-known Scandinavian manufacturer of loudspeaker transducers. Founded in , Scan-Speak still resides at our original address in Videbaek, Denmark. For close to 40 years, Scan-Speak has been on a quest to create loudspeaker drives, which can reveal the finest details in recordings, concealing nothing from the listener. This quest has resulted in many inventions, where distortion in the magnet systems and the moving parts of the speaker are minimised. All Scan-Speak transducers are hand-built in Denmark, with the utmost attention to quality at their core.

Scene: interior Munich High End Show, edition I am in front of the room where the Volya Bouquet loudspeakers are performing. I am puzzled by them and enthralled by the Ukrainian hostesses. I immediately understand that these works are colossal, for sound and design. I fall in love with them and we agree for a visit to the company. As we say in Rome: cotto e mangiato cooked and eaten: in no time flat. Just look at the photo below.
