Scanspeak makes some fairly expensive paper coned woofers. I don't think they think that paper is crap. A local dealer that builds its own custom speakers just finished a pair that utilizes 15" paper coned drivers from Scanspeak. The drivers cost the dealer $2,000 each. The speaker just came in and the crossover has not been mounted so I haven't heard them playing, but, I will get a chance.

Every material for drivers; paper, aluminum, kevlar, carbon fiber, nomex, ceramic, magnesium, beryllium, etc.... all have pros and cons. And incidentally, more people than SEAS and Scanspeak make great drivers. Each material has different characteristics that behave differently in different applications. Paper is not inherently good or bad. Paper cones are not simple card sock cut into a cone. The formula is typically a carefully guarded secret and they can deliver elite level performance. I find the paper drivers I use (Eton's Orchestra) offer a tiny bit of coloration which makes them engaging and incredibly musical. In the right application, paper drivers can simply be extraordinary. In terms of accuracy, I agree that magnesium offers some distinct benefits. I prefer Eton's magnesium driver to SEAS more because it is much easier to work with. The SEAS is very difficult to get the crossover just right while Eton's Arcosia works with simpler crossovers and delivers and incredibly smooth yet accurate sound. I actually prefer Eton's paper drivers compared to Scanspeak as well. But, this is based on my designs and my experience using lightweight but heavily damped cabinet material. The EXACT opposite of say Joseph Audio or Wilson who are producing high mass cabinets. In the end, a speaker is a complete system and you can't take a driver and say it is "the best" without the context of cabinet and crossover. A great driver in a bad cabinet or with a bad crossover will deliver a bad speaker. A modestly priced driver integrated with the right cabinet and the right crossover can be insanely good and in the end, it is the complete design that matters. Individual parts should be taken in the context of that system. |
@larryi -- Scanspeak makes some fairly expensive paper coned woofers. I don't think they think that paper is crap. A local dealer that builds its own custom speakers just finished a pair that utilizes 15" paper coned drivers from Scanspeak. The drivers cost the dealer $2,000 each. The speaker just came in and the crossover has not been mounted so I haven't heard them playing, but, I will get a chance. I wonder what the reason is for their 15" driver to be that expensive, and how the sonic results would ever reflect the price positively. I guess that's up to the individual to decide.. Arguments have been made that high efficiency drivers are more expensive due to the smaller tolerances required in the voice coil gap, but there are many great HE pro drivers that, when looking at their typically vastly bigger magnets, voice coils and overall size, compare favorably here to hifi drivers of smaller size and not least (much) lower efficiency. Go figure. It's telling then that when Scanspeak sets out to make a 15" driver, likely only no more than moderately sensitive at that, the dealer cost is $2,000 (even more for the consumer, I presume). Not to dismiss their efforts prematurely, but that's hifi in a nutshell. |
I don't know what sets the price for this particular driver. It could be that few units are expected to be sold, so the price of developing the driver is being amortized from fewer expected sales. I believe it is a newer offering. It could be a speaker intended to fill a particular niche--vintage speaker designs--and the price might be a reflection of what is available in that arena. I know people who have spent $5,000 to $20,000 each on vintage woofers. I cannot tell you what I would pay for a perfectly match pair of 18" Goodman woofers. The dealer said that it is 95 db/w efficient, so it is not a very high efficiency unit like many vintage woofers. Still, this would work well with modestly powerful tube amps. |

~~~~~~~~~~~~~~~ 95!!!!!! db sens,, in a 15 incher,,WOW, = $2k from a Scanspeak = bargain. One of those guys + a Seas W16 Graphene + a Seas Crescendo = blows anything from Wilson's in all shootouts. I just got the DavidLouis 6.5 wide band. For under $500, this driver looks stunning, The paper is soem sort of composite and has kick to the tap of my finger,,, Waiting for tech to open shop tomorrow so we can get the DL wired up N running/YT vid tomorrow. I am expecting stunning results,, Some tech geek over there in china knows how to make a wide band. This guy is a speaker guru genius. The Vox I had will not stand up in any fq's to this materful designed wide band from ~~China~~ Yeah I know, how often have I emphatically stated here,,~~China can not make a speaker~~, I am eating those words. Beats the Seas wide band in all fq's as well. I've been cking every inch of the driver for 1 hour, and am amazed at the contsruction/design. I do not think there is wide band in current production that will beat it in any shootout in any fq range. The lil 4 incher is extremely accurate in vocals. Has bass puch and highs that do not roll off til say 12k region, FOUR INCH wide band doing it all!!! I'd put this 6.5 up against anything from Feastrex/AER, Voxativ. Let me say this, although the Vox did not get its required horn cabinet, Vox will have to come up with alotttt more than what I heard with their AC1A demo in a 12x12x12 inch /1/4 inch plywood test cabinet. Vox/AER has many models, so i can not say how the shootouts will do down. Then again, @ $450, I could care less if Vox/AER/Feastrex blows away the DL. But again, the shootout might just be close ORRRR The DL6.5 might come out last speaker standing at speaker shootout at ~~The Old OK Corral. https://www.youtube.com/watch?v=YAFNVCXk93Y |
