  1. Geez... stop it with all the technical jargon! ..Way over my head!
  2. Quite a coincidence... I had Vandersteen 3A Sigs driven by a Bryston 3bsst for about 5 years. I used a Bryston BP25 pre-amp. Though they sound great, your Vandersteens are quite inefficient, so require a very powerful amp. ..And because of their 1st Order Cross-over design, they are also a bit fragile. A bit too much power can easily result in a blown driver. For this reason, I was always reluctant to really crank them which is something I'd like to periodically do with my 2-channel system. I now have Cornwall III's and absolutely love them. I use a McIntosh MA6600 to drive them. I love my mac b/c of it's build quality, aesthetics, it has tone controls, a mono switch, and the ability to volume match all the input levels. But the 200 watts/ channel my amp produces is wayyyy more than necessary. If my wattage meters hit 20 watts, the volume is so loud as to risk hearing damage and irritate my neighbors across my yard!. ..My usual loud setting is around 4 watts. So, keep the Bryston if you want, but know for certain that you do NOT need all that power. Heck, Brystons lowest power amp would be overkill. Enjoy the Cornwalls - you won't regret the switch!
  3. Not convinced. 99% of wood speaker cabinets made by top speaker companies are made with MDF, and that includes speakers that are so expensive that the incremental cost of using BB would be inconsequential. Vandersteen, KEF, Dynaudio, Legacy, PSB, Paradigm, etc. etc.. are made w/ MDF. As are the vast majority of Klipsch speakers that are NOT intended for installation in amusement parks, transportation stations, etc.. And even those speakers generally have MDF motorboards. Like I said, if MDF is such garbage, why are you all hanging out on the website of a brand that uses this material extensively throughout it's product lineup? ..Maybe form your own "DIY w/BBP" Forum outside of Klipsch.com.?
  4. Dave, Don’t you feel it’s bad form to endlessly trash MDF when nearly ALL of Klipsch‘s current speakers are made entirely or in part with this material? I mean, if you feel their present day speakers are such junk, then why spend so much time here? ...just sayin’
  5. Well.... It appears SpeakerLab has switched back. Here they comment on their "locally sourced, formaldehyde-free MDF" in their Behind The Scenes Video. Which implies that PWK might have a different opinion on MDF today as well. ..I believe it is even used in the new Klipschorn. http://slspeakers.com/galleries.html#speakers
  6. This thread is in the 2-Channel Home Audio section. And I don’t see why discussing materials is irrelevant to the topic. The title of the thread is "what are the best year model(s) cornwalls?" As a switch was made from plywood to MDF - from ver 2 to 3, I believe - I think my comments are germane. And if not, they certainly are not offensive. You can alway exercise your right to not participate in the thread.
  7. Your distain for people with MBA’s is curious. Do you feel this way about others with advanced degrees? Like doctors, engineers, scientists etc.? We live in a weird time when people with an extensive education are denigrated. And just to be clear it’s not that I dislike plywood 🙂 Its that I dislike it when people make blanket statements, like “MDF is garbage”. Because such a statement impugns the expertise of the great majority of speaker designers who feel MDF is the equal or perhaps better material. Designers like all of those that I listed earlier in the thread. Plus, you discribe a durability issue with MDF that neither I nor any one I know has ever experienced. Which would include dozens and dozens and dozens of speakers.
  8. Because it undermines yours and HDR's narrative that MDF is chosen because of cost rather than engineering considerations, including sonic qualities.
  9. Well I guess every speaker I've ever owned had sufficient adhesive integrity to pass the drop test because not a SINGLE one ever came apart after years and years of ownership. ..And EVERY one was made from MDF. ..Come to think of it, I don't have a single friend who owns an MDF speaker that spontaneously came apart, or suffered water damage for that matter. ..And like me, most have had kept speakers for many many years. My advice to speaker desginers/makers: Use whichever material makes for a better sounding speaker. ..Leave it to the owner to keep the speaker safe from falls or water damage; you know, like the way one treats EVERY appliance in their home. We don't pick our turntables, amplifiers, cd players or flat-screen TV's based on which can best hold up after being dropped, I don't see why we should assess speakers differently.
  10. HDR, I'm not trying to convince you what to do. And It's not for your benefit that I persist in my defense of MDF as at least an equal and perhaps a BETTER material for speakers. As for drop tests... For goodness sake, I don't make my component choices based on what will best endure abuse or accidents. ..As I've pointed out time and again, over the past 30 years I've had speakers from Boston Acoustics, Polk, Spica, KEF, PSB, Vandersteen, Paradigm, and now Klipsch and precisely NONE OF THEM has ever been dropped, or the unfortunate victim of an in-house water catastrophe. And every one was made from MDF - just like pretty much EVERY wood speaker these days. Speakers are not houses.
  11. https://www.svsound.com/blogs/glossary/speaker-baffle "A speaker baffle is the front face of the a speaker...and is often an under-rated aspect of speaker engineering." FWIW, I've only seen the term "motorboard" used by Klipsch. ..Nonetheless, they are the same. And the fact that Klipsch choses MDF for this "under-rated aspect of speaker engineering" for nearly ALL of their currently available speakers is interesting to me.
  12. What don't I have a clue about? Please be specific. Tell me which of the following is incorrect and why: MDF is easier to veneer. (it's surface is more consistent. No knots, etc..); MDF is easier to make precise cuts, to shape, to route for recessed drivers; MDF is more consistent from sheet to sheet; MDF is slightly less expensive, but it's significantly heavier. MDF speakers are probably more expensive to ship due to heavier weight (which challenges the "Bean counters prefer it 'cause it's cheaper" argument); Klipsch Pro Series speakers have MDF baffles. As for my profession? ..Not that it matters but I've been in Sales/ Marketing for 30+ years. 25 in Automotive, 5+ in Pharma. And I too have spent plenty of time working with wood.
  13. No, it is not much more expensive. It is more expensive, yes but not prohibitively so. If the likes of Vandersteen, Dynaudio, KEF, PSB, Paradigm, Legacy, and so on and so on could gain any sort of competitive advantage by using seven ply Birch, they certainly would. But they don’t. Today’s MDF has no voids, It’s easier to cut accurately, can be more easily routed to accommodate recessed drivers, and is easier to apply laminate’s, then PLY. Speakers that are going to be suspended and mounted in bus/ train stations, etc... like Klipsch pro series Can benefit from being ply because of the irregular stress is placed on the cabinet. Apart from that they’re only downside to a ply cabinet. That is, except it gives those who make speakers in their garage something they can seize upon and claim they do better than all of the brand names.
  14. If I had a catastrophic flood in my house my speakers would be the least of my worries as such a flood would likely destroy drywall, every appliance, my hardwood floors, my furniture, etc.. Ugh! And rather than having plywood speakers re-finished - which I'd have neither the time nor energy to do after a flood - I'd likely have them replaced along with everything else under my homeowners insurance policy. ..And my speakers have a 2" riser, so it would have to be an epic flood indeed. Less than an 1" or so I could probably get alway with just replacing the riser. Besides!! The Pro Series Speakers many here praise (partly) because of their plywood construction STILL HAVE MDF BAFFLES, so what then?? ..Seems to me they'd still be destroyed.
