Almost 24 hours since a post in this thread so an update. Almost done, a little trim on the back top rake edge and 2 roll up doors and it's done. Well except for electrical and a couple benches then deciding where the tools will go.

Another Happy Birthday for @grasshopper & @MicroMara & many more good ones!

Happy birthday to MicroMara too! Another candle on the cake and a trip around the sun!

@grasshopper I always knew you were a Capricorn and not a grasshopper. Then we have something in common on today's day and date, only that I am 7 years younger than you. Enjoy the day .

went outside for a very brief moment... frig brisk this AM. Weather channel sez 21`. Feels colder than that. They also say it's sposed to hit 70`. I'm quite OK with that. Days like this I can get away with a 5gal bucket of twigs for a fire. Once the suns come up, the drapes get pulled on the east side... and the sun takes over. a fairly typical winter day.

Mornin' all survived another b'day. 99 er..... 66 Was a quiet, uneventful day. .Just what I wanted. "Celebrated" by cracking a bag of Kona coffee... and playing the wife's stereo.... at a near antisocial level. Worked hard Monday so I could do little or nothing yesterday. The extent of my activity was filling my bowl and coffee cup. the R15M's went to their new home. @dtel nice looking shed. good job

Good morning everyone! I hope all is fine by you. I've been busy with the pup & not had a chance to lurk on the site. Please be safe.

In about 3 years @dtel will be wondering WHY he didn't build a bigger place!

Very Nice. Wanna come and help me build a shed?

Some of the Record Heads in this forum may also be movie buffs. New release.

Happy Birthday to you both!

Remember when the calendar for birthdays was easy to find? They're still there, just harder to find. With the average around here most people don't care to be reminded. The good part is almost everything we buy has a lifetime guarantee.

that was quick - wow-------looks really-----really good , waterproof , and no wood to rot , or mold or termites

Haven't seen him lately cool. Yes that was a different club for sure, lol: Pretty good so far. Saw the movie but...

Love this guy too! One of the best and a one man show!

You probably know this, but John Carpenter wasn't just the director of the movies, but also the composer of the score !

Just got shot with Moderna at 10:30 this morning. Called yesterday and upped it 2 weeks earlier. Easy process...

Happy Birthday MicroMara, seems to be a popular date, have a good day today. .

Happy Birthday to you too!

Another Birthday Boy --Happy Birthday George , May you never get Old ,

Eric is still young , checkout the birthday of @Sancho Panza 1918 , aint no way he's 104

Around here they call it a pole barn when there are no sides or cement, usually anyway. Like to store hay or park equipment under, but I don't care what it's called if I can put my stuff in it and work out of the sun. There will be a little wood for a counter and a couple rolling tables, but they will be treated wood, I have had enough termites already, they can do some damage quickly. One corner is all I need, the speakers will be the first thing to go in, even if I have to run it with an extension cord while wiring everything. Thanks everyone, seems like it took forever to have space to work.

HAAAAAPY Birthday BRO-----------------may you stay Young in Spirit

Grasshoppers birthday????

Happy birthday grasshopper. Oh to be 66 again knowing what I know now.

Looks like it might have good corners too.

@grasshopper HBD WillyBob, you'll probably see 99. In the eyes of your life insurance company, when you hit 100, you win and get your policy amount! @dtel that building looks great, and made to last. Probably 90% around here are built with wood, but I know you have a different wind load. We would call that a pole barn, but I like the term garage.

Water skis at Mavericks

Cannon technology was much improved by 1812.

Probably right, it happens to everyone. Going to try to keep it unfilled, I want a place to work, it's the main thing. But your right.

Steve Martin could play the heck out of a banjo! I wasn't aware of that for a long time.

Gotta love Lester & Earl

Found some memories on youtube, the tv sound stinks now so fired up the little polks and it's all good. @billybob ever see these guys back in the day? We'd just get in the car and go find the good sounds, they'd hit town a couple times a year. Talent and varied sounds to their hundreds of tunes it seems like. * Oh I found my dancing shoes in an old foot locker in the shed... HA out the door they went!

(This is a continuation of a deeper look into horn-loaded loudspeakers as a result of an in-depth review of Floyd Toole's book (Sound Reproduction, 3rd edition). Many threads have been about horn (a.k.a., waveguide) loaded loudspeakers on this forum. This isn't the first--nor will be the last. What's different about this thread is that it addresses those readers that are a little more than "just a little curious" about horns/waveguides and why a company like Klipsch produces loudspeakers that effectively 100% have some sort of horn loading of drivers. (Even earbuds are "waveguide loaded": the ear canal is a waveguide). This thread is aimed at those people that would interested or motivated to buy this book and read it, but need just a little help getting up on the technical language. In other words, this thread is a gloss or explanation/exegesis of this text: This book is available from Parts Express (in the US) and elsewhere. Here is the book's website for those living in other countries: https://hornspeakersystems.info/. It's not an inexpensive book, but when you see it, you will understand the price--it's over 1000 pages--large pages and has many thousands of figures, etc. _____________________________________________________________ "Why horns?" That is the subject of this entire thread. Based on another thread that reviews Floyd Toole's book, Sound Reproduction (third ed), it became clear that an in-depth discussion of horn-loaded loudspeakers, and horn/waveguide theory in particular, is needed for those that wish to learn more, and which are not deterred by the technical challenge of learning more about it. Why here? Klipsch has always been about horn-loaded loudspeakers (even when it wasn't cool--which was a lot of years). As such, I consider the Klipsch name synonymous with horns. If that changes, I would be extremely surprised. I feel that an in-depth thread to counterbalance the "frequency response is king" direct radiating monkey coffin enthusiasts...is sorely needed. I've been waiting for someone else to do it. It hasn't happened, however, except for the author of the book that we'll be using (released in late 2019)...Bjorn Kolbrek. (The first part of the book--the history of horn loudspeakers, was mostly written by his co-author, Thomas Dunker). This is as good a time as any to start in this forum. I think PWK would actually be flattered to know his technical legacy survives. I hope that I'm up to the task. I've had a lot of practice of late (tutorial threads) and good familiarity with the subject matter--albeit at an engineering ("educated consumer") level. If anyone in Klipsch engineering wants to take on this task--I'll get out of their way. Perhaps this thread might kick-start that involvement...or perhaps not. Comments from Klipsch design engineering staff are always welcome. As this thread develops, I expect the format to be refined as we go along. Questions are encouraged, but this is not a "social media thread": if you want to talk about the social aspects of owning and listening to horn-loaded loudspeakers...start another thread! You can link to those threads from this thread if you feel it's relevant to do so. If you are still bothered by the technical language even after reading the gloss explanation here, you still have a couple of choices: You can ask questions about those specific horn theory topics here or perhaps the mathematics of horn theory here, or If you are still bewildered by the whole subject, start another thread and talk about it, and you can link back to that thread here for reference. My initial approach is to follow the book's table of contents, starting at chapter 9 (page 413) of the book. If this proves to be too laborious or not useful from the perspective of "why horns?", I reserve the right to change it up to keep the thread moving forward. Here is a table of contents of the book: https://hornspeakersystems.info/images/pdf/TOC.pdf. The contents of chapter 9 are: Title: Horn Loudspeakers - an Introduction 1 Efficiency 2 Impedance Transformation 3 The Horn Loudspeaker 4 Directivity 5 Basic Topologies: 5.1 Front-Loaded Horns 5.2 Rear Loaded Horns 5.3 Full Range Systems 5.4 Multi-Way Systems Since there are 30 chapters (22 chapters to go, that are specifically related to this thread) and three appendices...comprising over 500 pages, this is going to take a while. We're not in a hurry, however: the Klipschorn was designed over 75 years ago and it's still around. 😉 Chris

Sure looks nice! Cousins to mine (which I also bought in 1979)

yea behind not ahead...I almost got named Valentino

Now he tells us ,

Happy B'day Grasshopper. I'm 34 days behind you ...if a six turned out to be nine...I don't mind......

Speed of sound varies with conditions, but generally 1125-1135 feet per second is a good approximation. So 27ms equates to right around 30½ feet.

Voice coil is 8 ohm on this recone kit. Please ask for 4 ohm version.

If it was not for the commute.

Heck Yea! Love `em all! But those guys above.... them and UFO were the only times I danced until I saw Jimmy V and the Fabulous T-Birds at the Palomino Club!

@JohnJ To be sure man but, cannot say that I have at first glance. Will get back at you. One of your forte, think you have seen more than me...lol. Do like some black oak, new riders, outlaws. Atlanta Rythym Section we both dig hard. Little River Band Georgia Satellites... Cool And happy new year !

I decided to try using ferrules on my Speak Ons to keep the strands of wire together. Got me one of those screwdriver sets from harbor freight like @wvu80 suggested.
