Sorry about your buddy - hold on to the memories! I had a put down a seventeen-year old-mutt a few years ago and it was one of the hardest choices in my life.

I have a 15.5 year old shepherd mix that seemed to take a turn for the worse on Tuesday. No doubt the best dog I've ever had. An old girlfriend and I got him from the pound as a just weened puppy. And even though we no longer date, I still go over to see him every day along with our other dog. His back legs and hips are pretty much done.

He seemed a lot better yesterday morning when I stopped by. But she called me last night around 6:00 asking me to come over. He couldn't get up off the floor so I ended up sleeping next to him all night last night. What was rough was seeing him reach out his front paws out and pull himself closer to me and put his head on my arm, he always used to do that. You could just see the look on his face that he knows it's time. Luckily he doesn't appear to be in any type of pain.

After almost 16 years, we just can't expect him to go much longer. He's given us a lot of good times. I've never had to do it, and I know it's going to be horribly difficult, but we decided last night that we should put him down. She took off work today. This morning he looked a little better, so she thinks she'd rather spend an extra day or so with him. We'll probably make the appointment for Saturday. It's going to be very tough.

One thing about Bailey that everyone used to like was that he really did smile a lot. This photo is a little distorted making his snout look bigger than normal, but it did catch his smile.


Oh man.... Yes I quoted the the whole post but we're on on new page.

Had a white Lab(Sammy) that had the same facial expression as you're baby. She went 17 years, fat and happy and loved to death. Hip finally gave out and she became incontinent.

Was a crazy feeling taking her to the Vet with my 18 year old daughter to have her put down realizing my daughter was ONE when Sammy came into our lives.

Seems so unfair, they are built pretty stout, you'd think they'd be good for 30 plus years.

That dog ruined so much stuff for her first 7 years but I would never trade it for anything.

Giant lump in my throat,

Darrell

Thanks guys. Really. I think men get more attached to dogs than women do. Or at least the bigger dogs.

I went to work today after sleeping next to him on the floor. Figured I'd work today while she stayed with him, vice versa tomorrow. Then Saturday would be the day. But she called me around 1:00 crying saying he was doing worse and couldn't bare to watch him struggle anymore. So she made an appointment for today at 4:30.

That was harder than I thought it was going to be. I had to carry him in and it just didn't feel good at all. Last picture is the real tear jerker. Haven't located the "Dingo Years" where the vets actually asked if he was a dingo. These pictures are when he was older and taken at my ex-girlfriends house.

Happier days:



His fake "You wanna piece of me" face:




And towards the end. Still a good looking dog, but 35lbs less than his 105lb muscular days. Can't believe he made it 15.5 years.



Thanks for the good years Bailey.

Haven't seen you post here lately Tack. 17 years from your lab sounds great. That's an amazing amount of time from a bigger dog. Like you said, the way they're built, it's shame they can't go well over 20 years old. Yours got pretty close though.

post #3576 of 9844
My sincere condolences fir your loss Eric! As an animal lover, I find myself sometimes more sympathetic to the loss of such loyal animals then some human beings. I have owned three dogs for 14 plus years and lost them all in the short span of three years. One died at home and the others were taken in to get put down. It was a difficult experience for me that I will never forget. You start thinking about all of the good times and family functions where the dogs would run around looking for someone to give them attention. There was never a time where they weren't happy to see me when I got home from a long days work.
Sorry for rambling but I feel for you in your currrnt situation!!! Cheers to what sounded like a terrific companion.
post #3577 of 9844
Sorry Erich, but I know just how you feel. My best mate of 16 years died in January. he was old and a bit sluggish, but seemed good until just near the end when it was sudden and dramatic. I left him because I couldn't get out of work that day and had booked the vet for that arvo as I wanted him to die in my arms, but when I got home he'd already passed away.

I decided I'd never get another dog as I was so torn up about losing this one. Two weeks later by chance I saw an another poodle advertised locally. She is a beast and a terror now at 20 weeks, full of life and energy and so different from the last boy.

When you're ready get back to the WG and CD work. Leave mine until last if that makes it easier for you as I'm not in a hurry and they'll likely be more work since I'm O/S.
post #3578 of 9844
Really sorry for your dog, Erich. I lost mine a few years ago and still miss them.
post #3579 of 9844
Erich, I'm really sorry for your loss. I got misty eyed just reading your posts, and I can't imagine how I'd react in the same situation if either of my two became ill.

@Rybaudio = www.rjbaudio.com ? very informative site.
Thanks for your feedback. I scaled down to SEOS-18 with Beyma CP380 and 6 Peerless 8" woofers ( Fs 41 Hz, 40-3500 Hz, 92 db, Qts: 0.53 Xmax: 2 mm). Will be used with bi-amping of 2 additional BEYMA 15G450N subwoofers ( bidding right now...). I cant resolve these questions : why is a SEOS 18 judged inferior to the smaller sizes ? Normally a larger horn makes a smoother transition. Where is my error ? I would like to mount the SEOS outside the cabinet to reduce interference - and the look, is this ok ? For the XO, I would prefer a 1.order at 1800 ( simplest setup, but parts from jantzen-audio.com), to exploit the upper frequency of the woofers better. Does this make sense ? How would you cross over with these drivers ? Can I cheat the system into a 3-way design like this ? Thanks to all Marc

Toscano-

I hate to burst your bubble, but I'm usually the guy who does that around here. Designing a crossover is not as simple as picking a frequency and slope and applying the "textbook" crossover using a simple formula. Simply put, you will get terrible results and waste the money you put into the project.

You will need a combination of measurement equipment (frequency and impedance), simulation software, and some design knowledge. It is a bit of an undertaking, but IMO anybody is capable of doing it. Of course, you have to want to learn the process. You will be learning on the fly with a relatively complex first project. It will be quite time consuming. Oh and there aren't any simple "how to" guides either.

In a nutshell, unless you go to the trouble of what I just described, you are far better off simply building a preexisting design such as one that Bwaslo has posted. There will be more designs too.

The other option is active, but that still requires measuring frequency response and some of the same knowledge. It is definitely easier though it will cost more.

I put one of my cats down 2 months ago and had the same feeling, their health degrades very rapidly, as if theyre designed to cling on until they hit a tipping point where exhaustion sets in over just a couple of days.

It is not a gradual thing and thats why it hits us very hard. Maybe its because a week for a dog or cat feels much "longer" as they live a shorter life than we do. I'm not sure.
post #3584 of 9844
Very sorry to hear about your loss Erich. It's so tough to loose a pet, especially because it seems as though so much of what they care about is their human companion, which really drives home the feeling that you've lost a loved one...

My condolences...

Hi Cocostan, Thank you for the statement. I am choosing an existing speaker kit or trying this project for fun. There is a seasoned diy builder around to help designing the crossover, a friend to build the enclosure, plus one to help in soldering. The reason why I dont buy the speaker kit by Eric is that I primarily look for quality, a low budget solution : why waste time for that ? If my endresult is bad, I still have the speakers and can start all over. In contrast with many diy builders this project is not a scope in itself, I want to actually hear music with the boxes and get on with something else. This implies that I am looking for a cookbook over here, not a philosophical or interpersonal debate. I have read this thread for some time and know who is actually delivering factual knowledge, I remember your name for this, and the specialist for 3-D design. In my opinion, seasoned veterans should be able to produce a list of possible speaker and crossover configurations along with a boxdesign, this is the relevant criterion. Recycling old cabinets, sticking to a 2-way design and enganging in year-long debates over how many screws to use in a waveguide or similar stuff is questionable. Thank You.

I'm not exactly certain what your post is referring to, but I'm talking about crossover design not enclosure design. I'm sure you will do fine with the enclosure design and construction (probably better at woodwork than me...its not my forte).

Crossover design is not trivial and your statements like "prefer a 1.order at 1800hz" show that you don't quite understand crossover design. I'm not pointing that out to insult you. It is a common misconception. It is a mistake you do not want to make and I can guarantee you that you will be very disappointed in the results. This isn't opinion, conjecture, chest puffing, etc. This is simply a warning from someone with experience looking out for another forum member.

If you choose to go down the path you seem to be going down, I ask that you not bad mouth any of the parts you choose, specifically the SEOS. The SEOS is well designed but if it is not properly implemented it will sound terrible. Nothing can overcome a hack job of a crossover and with all due respect, what you are describing is a hack job.

mr. c., he is saying that he doesn't want to learn crossover design, but rather he expects somebody here will do it for him. he is essentially looking for somebody to design a kit/cookbook for him that includes cabinet design and crossover design using his choice of drivers.

If you muck it up and have to start again, you'll need to buy more xover parts, as there's no guarantee that your original ones will be correct for another design. If low budget, high quality is the goal, then a known developed solution gets you there in one step, usually for a lower budget.

Marc, I think my knowledge level is somewhere in the middle between you and the experts, so let me try to answer your questions...

I don't think the SEOS-18 is inferior, but I think the SEOS-18 is less popular than the smaller sizes for two main reasons:
1. It is possible to make high performance 2-ways with the smaller SEOS-12 and SEOS-15.
2. The SEOS-18 is physically larger, and smaller sizes are often easier to aesthetically integrate into a room, so people pick the smaller sizes.

However, that doesn't mean that the SEOS-18 isn't good. If you want a speaker where the waveguide holds pattern control even lower than the smaller sizes, the SEOS-18 can do that.

Yes. You can definitely mount the SEOS outside the cabinet.

I don't know. Will you run into audible uglyness or damage the CD with such shallow slopes? Will the direcivity of the waveguide transition smoothly to the midwoofer(s) (as would show up on one of those colorful polar response plots)?

As others are indicating with their responses, I think crossover design is simply more complicated than just picking a frequency and type. For instance, I think I read that the CD in the waveguide has a characteristic response slope that you need to account for in the crossover design. And it seems like many real crossovers are not just the symmetric "low pass, N order @ X Hz" and "high pass, N order @ X Hz" that naive intuition would suggest.

Good chefs go to the market with an open mind and select the best ingredients to make the best food. Mmmm... this thread has 2-ways with a variety of midwoofers (to be used with separate subs) that sure sound delicious!

As a variation on the 2-way + sub(s) design that may better match your desires, Pi Speakers recommends using flanking subs crossed at ~150-200 Hz. Wayne Parham from Pi responds with some info on this thread:
http://audioroundtable.com/forum/ind...71134&th=17058

You can do what Wayne describes with SEOS-based speakers, Pi speakers, etc., but the subs are more specialized than the typical subs intended for HT, since they need to play higher. I suspect that your planned subs would work fine for this arrangement. Handling the crossover between the mains and the subs is another challenge for which you may need to think ahead and buy or build specialized hardware, since an HT AV receiver won't do this.

Thanks for the comments about my dog. It will be different for a while, but it will get better. My ex-girlfriend and I were looking back through photos and comparing to the past 6 months, it's surprising to see just how much he had aged. You don't really see it because it happens over such a long time frame. What bothers me that I didn't mention is that we've been feeding him really good food since he was young (eukanuba then Bill Jack). 4 weeks ago her brother brought his dog over for about an hour and some of his dog's food. I guess Bailey liked it. So without me knowing, my ex-girlfriend bought some of that dog food. It was Purina Senior 7 or something like that.

She gave him some the day before he had major problems. She said he really liked it and seemed excited to be eating it. I was aggravated that she gave him a different food. I didn't know this until the following afternoon when I went over I saw that he threw up about 4 times and went to the bathroom about 5-6 times in the house.....which he NEVER does. He was laying on the floor and could barely move. I carried him outside and thought he was going to die at that point. He then actually went to the bathroom while laying on his side. I assumed he was completely exhausted and dehydrated after everything due to his age. Over the course of 3 hours I was able to get him to drink fluids and eat a very small amount of other foods. I called my ex to come home from work. The next morning he seemed a little better, but not great, and I assumed he would get back to normal. I wish I hadn't, but I told my ex that she shouldn't have given him different food and that she was lucky it didn't cause problems. It was the following day he really took a turn for the worst.

My first thought was the abrupt change in dog food. But different foods never bothered him much in the past, plus, it wasn't all vomit and there was no diarrhea which you would expect. Obviously my ex-girlfriend started to feel extremely bad as if she had brought on our dogs death. You can imagine how bad you would feel after this. I wish I hadn't said anything about the new food causing problems, but I really did think he'd pull through.


2 days ago I remembered reading something about Purina causing dog deaths and it seems the stories number well into the hundreds in the past year or so. Food laced with bad chicken from China that causes the exact thing Bailey went through in his last 3 days. That really bugs me.... a lot. But garbage day was Thursday and I tossed the remaining food so she didn't have to see it again and get upset. I guess we'll never know how long Bailey might have went for. I truly believe there was something wrong with that food and not just the change in food itself that dehydrated and exhausted him from throwing up.

Now back to the waveguides.

As mentioned, I picked up the pallet that was shipped from Poland and spent the day packaging up 95% of it. I've got 3 larger horns that I must get boxes for, but the rest are done.


The SEOS-10 one piece baffle is much nicer than the pictures show. I'm really glad I asked them to make these. I showed a few of my friends, some that don't even know what it is. The first word from most of them was "Wow", even from each woman I asked too. Definitely super high WAF. They really are that nice. I've got to start working on an equally nice box for them.

They can be ordered on the next pallet, but I'm still not 100% sure on price yet due to their weight. They're not going to be very cheap though and they might be better used in a full speaker kit.

I'm debating on another color for them as well as black. Black looks great, but that will show all dust and fingerprints. And there will be finger prints because everyone that looked at them immediately reached their hands out to touch them.

My official flyby since baby is now here and the sleep deprivation of taking care of him and freaked out mom is making me a little loopy...

SEOS-12 plastic waveguides and CDs were supposed to ship by now, correct (to Erich on one shipment not out to customers)? Update?

Thanks.... I'll try to check back in sometime in the next couple days... if I don't fall over or lose my mind from lack of sleep

Everything shipped 5 days after it was suppose to. One of the companies that makes parts was going to ship directly to me, but I asked them to ship their stuff to another company so we could combine shipping. There was a slight customs issue with some paper work. But the 2nd company confirmed that they received the parts and all was taken care of.


I've got some other interesting things coming as well. I think I went a little overboard......imagine that


Looking at my schedule, I should be done with the main landscaping stuff in about 2 weeks. Then I can step back from the employees a little bit more and ease up on 'slave driver' mode. After that, I'm going to put more of my time towards audio stuff.

GROUP BUY UPDATE:

I received an email from Paypal today. Someone that preordered in March filed a dispute with Paypal that I failed to ship their waveguides for this preorder. I think Paypal charges me $20 when there's a dispute and I'm sure something goes on record that I didn't ship something that was paid for. I knew I shouldn't have done that preorder. I should have just handled it on my own as originally planned. I think around 200 were preordered, I'm handling over 800 more by myself and the compression drivers.

I contacted him and asked if he knows this is a preorder and he does.

Quote:


I don't know you from Adam and while your pursuit may be admirable....It is not that I do not want the items ordered it is that there has been really no proper updating as to the whereabouts of items ordered. This leaves me uneasy as to what the status is on the SEOS waveguides. At best you leave vague messages with no real information. More time is spent talking about compression drivers which is a separate issue entirely. Using their delay in completion as a reason for the delay in shipping the SEOS waveguides is not valid. I find this disconcerting to say the least and not the way I run my business when dealing with my customers.

......... Just know that if the SEOS-12 waveguides are not to me before the Paypal May 9 deadline to file a claim I have no other choice than to proceed with a claim.



So I just want to make sure everyone knows that I can't ship until I actually get them. Not really sure what I can do differently. I'm sorry if I've caused anyone problems or worry. From what I've read, I think this injection mold process is actually going faster than normal.


UPDATE


The SEOS-12 waveguides and compression drivers have been shipped and should be arriving in about 35 days depending on customs. I'm not going to take people's preorders and then leave. I've also put a lot of my own money up to get these made along with compression drivers. All I can do is promise that it's done and that they are coming.


IMPORTANT


If anyone changes their mind about preordering the waveguides, just let me know. I have zero problems refunding your preorder. But please don't file a claim or complaint with Paypal saying you paid for something that I didn't ship.....when they haven't even arrived yet.
post #3597 of 9844
Erich, you were very clear about how this was to work. If I were you, I'd just refund that guy's money and ignore future orders from him, let him contract with China to make some waveguides all by himself.
post #3598 of 9844
He should have contacted you first than go through paypal... You're always going to have that one guy out of the bunch, maybe two.

Anyways, can't wait to get my share of items. Thanks again.

Agreed.
It's not even that much for the pre-order of the SEOS waveguides

Not to mention everything was listed in this thread, and you update it quite often and thoroughly. Vague? Hardly.
Seriously I would be offended as well, hope everything works out and you don't lose any paypal cash. Regardless of how much it is, it's the principle.
You still have my business when the time comes.

Did he not see the Deltalite II 2512 and 12a crossover?


Just wondering as I never sold anything through paypal, how does a paypal complaint affect you?
