Henry, the "know it all" did not seem to realize that just because you xover the tweeter stupidly high you might have done it to keep the output below say 5-10k from being exaggerated all the while extending the top end above 10k out to inaudibility. I do not believe in "supertweeters". The T-90's job was to extend and flatten the response[/b] of The Horns above 14-15K where the 126 actually starts to roll off.

Numbers are funny things.............xover at 30K and 6db will be down 6db at 15k.......and the T90's are >100db efficient. I cross them high to lower the output in the audible range, not because I think I can hear to 30K!

Steve, hope your foot is better. Steve is correct as to my thinking........the efficiency of the pair also is damn near perfect. Another factor is the "bass driver" is a full range unit. This allows the series xover because of the extreme overlap the drivers have. A lot of stars aligned for the pairing to work as well as it does.

Well, this has been a tough one. As the years have gone by HFest has degenerated (not a complete bad thing) into a party among friends. We just were not sure if we should do it again. Now, keep in mind, it was never about "selling stuff" but rather we just wanted to see the folks who have supported us and as an opportunity for some stupidity and fun.

So with that is mind...........yea, the house  will be open. The 1st weekend in May as it has always been (2-4th).

We'd love to see all of you who have come in the past and of course anyone else who would like to participate in a little audio and lots of stupidity and maybe a little fun.

I just got 8 tubes for The Beasts, have new Heils, and of course the best line stage on the planet and that is The Truth (pun intended)! Bring anything you want and we'll hook it up but keep in mind this year will be all about seeing folks and less about audio.............I would guess.

Ok guys, many of you have come to the Hornfest over the years and gotten to know others that show up. Our member friend and my friend for decades, Tony  ( he is Tina's brother) is brother in law to Larry. There's video of Larry playing one night at Hfest.

Larry was married to my friend Tina for like 40 years and I've known her since I was 15-16. She was a very nice woman, kind, and  both smart and witty.

Tina passed away Sat. morning from a battle with pancreatic cancer. She fought hard and did what was told she should do but she lost the fight.

For those of you that do such things, a prayer for Larry and Tony in their time of grief would be welcome I'm sure.

I can not  imagine the pain they are going through and I hope it gets less as time goes on.

Victor, on old Magnavox TV's the Yoke (an xformer on the tube) would rattle. It was a common problem and drove people crazy. We fixed most by wedging toothpicks and shit in them. Stuff like hot glue and silicone had no effect.

I spoke with Don and he said it is possible something in the p/s is dying and could be causing them to hum. He doubts this is the case but it could be. He said if you can put pressure on them or squeeze them and the hum stops then it's probably just mechanical. If not he said you may want to have them checked out or just wait and see what happens.

VRod, yes, the windings and laminates can vibrate inside the case. It does not mean it will fail. Can be a bitch if even possible to eliminate,

7  General Category / Music / DAMN, I can hear it on my stereo!!!! Can you? on: January 28, 2019, 10:39:42 PM
I saw this at a manufacturers site tonight. I was astonished. It's there, plain as day!! Why have  I (we) never heard it? Well, you need to be at a very loud level. This what I read....

"One of the tests we use to gauge our audio quality is if we can hear Lindsey Buckingham's f-bomb, whispered almost inaudibly just before the first note on 'The Chain' on the Rumors album. (Betcha didn't know that's been there since the '70's!) It's normally only audible through a set of good headphones on a good system turned way up loud."

Am I the only one here who did not know this and is your system good enough? I can easily hear it on a copy made 10 years ago. Have not tried vinyl yet...waiting on IC's...all mine died! WTF?

Vrod, From your post it seems that it must be mechanical hum from inside the unit if the speakers are silent. That may or may not be hard to "fix". If it is coming from the amp itself and not the speakers then pull the top and listen.......

Sonic, please, for God's sake, please, tell me you know Tony was being sarcastic! He was and you are correct in your statements. Smiley

Tod, there is nothing to check out and politicians have nothing to do with this. It's like worrying if you can shoot a semiautomatic. They are completely legal anywhere in SC, at any range and for hunting in SC. There are no restrictions in SC. No one will even notice unless you want to show it off. They are not "shady" and there is simply nothing to think about or consider in SC. The range officer will think you are "polite".

Unless you are hunting on private land and the owner is some kind of idiot that does not like less noise you are good to go anywhere in the State, in this case (private land) he may say you can't hunt on his property with it, which of course would be absolutely stupid and I'd not be around that kind of idiot in the first place. Every day you wait is just another day gone. I won't shoot a rifle without one. Why would I? I like my hearing and a can and muffs pretty much insure it's not being damaged at all. The muffs are overkill but I like overkill.

The xover will work with any amp except digital. It too is a non issue! Smiley

Order the damn things!

Tod, boy are you thinking too hard! Allow them? They will welcome it. Tracers and Tannerite are NOT allowed at any range I know of! A can is the exact opposite of those things. They will THANK you for having it. No issues using one for hunting either. No one is against noise reduction and increased accuracy!

I built all mine using a "form 1". I had some hiccups and baffle strikes but it's all sorted out now. The only advantage was the cost. They are NOT as good as a commercial one but "good enough"

I worked out the xover years ago. It works for any amp except digital amps.

Get a spare pair while they are almost free!

Tod, spend the money, wait the time and get a can for the M&P. You'll kick your self in the ass for not doing it sooner. Get a .30 cal. Then you can use it on anything. All of mine are .30 cal and work on all the MSR's (.556 & 300BLK) that I have as well as the .22's. When on the .22's they are Hollywood quiet. Less noise is a good thing!

I sure hope all of you that have The Horns snagged a pair of Heils. They were almost free.

Xover is easy and I'll tell you what you need and where to get it.

Thanks guys, it does seem like a short time ago she was fetching us beers at Hornfest for tips. She made a fortune that year. Many of you have actually seen her grow up. She thinks of all the Hornfest people as family BTW.

Merry Christmas everyone!
