Like I said...you get what you want to get, and I will get what I want to get...some of your points are at least partially valid, while others show a lack of real knowledge or advanced experience in woodworking to include certain tools, techniques, power tools, necessary jigs and such that most people don't have or have never used to make things easier/quicker to do while woodworking. IOW, I AM NOT TELLING YOU what YOU SHOULD DO...so do as YOU PLEASE...just don't attempt to enlighten me on what I already have lots of experience in doing unless you really know something I need to know. Your tirade has NOT shown me that! All I see is your OPINIONS and an attempt to prove it with salesmanship techniques represented as facts to support your OPINION. You apparently don't even understand much about adhesives in woodworking, to include how they actually bond and what materials they work best with! MDF sucks bigtime when adhesives enter the picture! It is the WORST for effective bonding strength of adhesives! It is adhesives that ARE SUPPOSED TO hold things together well..not fasteners. Drop tests also show that MDF sucks...especially in corner or edge drop tests! MDF is almost impossible to repair, too! If MDF is so good, then why isn't it used much in home construction?? Because it has no STRENGTH on its own! It cannot bear loads! SO, do as you want to do...and stop with the continual tirade here to ME! You will never convince me of its "superiority" as a wood-working material! Quote Link to comment Share on other sites More sharing options...

Certain materials can be relatively easily repaired, others NOT! Y'all keep in mind that this entire thread was very old and just brought back to life the other day...I still don't know why, though! I'm guilty of bumping the thread and bringing it back to life. I ended up here after going down a google rabbit hole after recently acquiring my Cornwalls and saw that you may have built mine so I quoted you. Didn't know it was going to start a wood vs MDF fight 😆🤷♂️. And I'm just going to assume you built mine since it seems most likely and it can't be proven otherwise, due to Frances' excellent sanding haha. 1 Quote Link to comment Share on other sites More sharing options...

No worries, I was just thinking that others had not noticed the original thread was from 2003...and were posting to that section...maybe expecting replies from some people who haven't been on the forum in many years and may not even be alive anymore. As for "an MDF fight"...again, no worries...some people like to troll others, but they end up becoming ignored sooner or later, get frustrated, and eventually look for somewhere else to play their games. Otherwise they get banned and are forced to leave! It is what it is. Quote Link to comment Share on other sites More sharing options...

Baffles are little wood thingies that go inside some of the speaker cabinets. 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.

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. Quote Link to comment Share on other sites More sharing options...

HDBRbuilder Posted October 15, 2019 Share Posted October 15, 2019 Lesson 1: DROP TESTS on box-type loudspeaker cabinets are conducted for a number of reasons, ONE of the MOST IMPORTANT REASONS is to test the bonding of the adhesives used in the construction of them and to determine if it is truly bonding well at points of panel joints. It can also be used to determine the superiority of different joinery types in order to make final production changes. The entire concept is to have the box joints come apart, for one reason or another, and to note at what height of drop it finally did so. At this point the strength of the box-build can be used for comparison purposes. As for bonding strength of the adhesives used at the now-broken joints, the breaks are analyzed to determine how well one panel bonded with its adhesive to another. If the break is a clean break, then the bonding was not very good. OTOH, if part of one panel is still stuck to the other panel, then the adhesive was able to make it into the fibers of both panels, prior to the adhesive completely curing....and a much better adhesive bond had been achieved with that particular adhesive and panel material type. SInce the adhesive bonding ability is the goal, it can be compared to other adhesives and or other panel materials and the results of their drop tests. This allows for the ideal material to adhesive combinations to be determined. But, it also allows for determinations of which combinations still bonds well at a lower production cost for adhesives and/or panel materials. Many other things can be determined, but these are considered two of the most important things gleaned from drop tests. Quote Link to comment Share on other sites More sharing options...

They where 1984 vintage, and yes they were made of BB, and smothered in oiled Walnut. 😎 My sublines have been reset a number of times back to zero since I joined the forum in the late 1990's. It has something to do with their making changes to the software on the form on an occasional basis, from what I have read. My post count is fairly accurate, I think...but I have never tracked that stuff closely because it is no big deal to me. I presume your1984 "baltic birch" Cornwalls were not factory built. That wasn't the standard material used for Cornwalls. if they were factory-built and they came from the factory with black walnut veneers finished in oil in 1984, then the substrate would have been poplar lumber-core plywood...and NOT baltic birtch...until they started using MDF, years later. I left Klipsch in October 1983. it was a few years after I left before they went to MDF in the panels. The MITERED CABINETS were still being assembled using chain corner clamps to secure the glued panels tightly while being constructed. The Cornwall side panels were too long in length to use pneumatic-box-clamping methods to build them successfully on a regular basis. They would bow inward too much and a good tight miter-joint would not be achieved. It was a number of years after I left before they went to that kind of clamping for the construction...although they had already moved to using that system for the building of mitered Heresy speakers well-before I departed.

Last I checked, no amplifiers, R2R tape decks, cd players, turntables, tuners, flat-screen TVs, etc... were engineered with water resistance in mind. Why on earth do speakers need to be? i’ve had all of these for many many years and none of them have ever fallen victim to water damage. I find this obsession to be quite hilarious. It's like you're offering a solution that is in search of a problem. I've had probably 20+ pairs of hifi speakers over my lifetime and NONE has ever been water damaged. ..So for me to ever factor that into my selection criteria would seem patently redic. I’ve Notice that some of you have your system set up in your garages. Well, maybe that’s the problem. Set your Wi-Fi systems up in your house and maybe you won’t need to worry about water resisitance. Our place in Arizona was flooded from the unit above it last year. We were not there at the time but were planning on driving down a week after this happened. Everything in the condo was destroyed by water and/or mold... except for my speakers, TV and stereo which was in the living room and it took months to repair and renovate. We were lucky that our place is watched and checked regularly when we are not there so the water leak was found fairly quickly and stopped at the source. Still, I spent weeks and weeks living in hotels while part of the reconstruction work was done. It was so hot there last summer that even my iPhone would shut down from being over heated. Scottsdale in June and July is not for me. Given the choice between Hell and Arizona I'm thinking Hell is likely colder in the summer months.
