Replacing the K's woofers!!

[pennysdad]

Thanks George!!

No voice coil is bullet proof. You thrash 'em, they overheat.
Think of electric radiators. The more volts, the more they WILL glow...
It usually happens just as you're thinking ".... that's the best I've ever heard them." That's when they die.
You just have to back off that 10%.
Once you've done it a few times, you'll start to recognise that point.

I'm curious as to what the meters on your amp were telling you? Were they on their second way around????? LOL.

George they were as loud as I've ever had em. Things were uncomfortable physically anyway...if I had to guess 250 continuous 450 peak .

Well there ya go then!
Lucky you didn't implode. [it happens...]

Woofers are like racing, you don't know how fast you can go until you are not going anymore. (I don't like the word crash)
My JBL 252-8 woofers are rated at 600W RMS continuous. There is a story at West LA Music about a guy who connected a quad JBL woofer cabinet to 120VAC for a second and the woofers hummed at 60Hz and didn't blow, that is 1800W RMS.

Too damn busy at work..,.tired of having a target on my back for providing what folks need so they dont starve or freeze to death. Other than that Darc../...waiting for the circus to come to town!!

No target for me Lee, we love you guys...

The feeling is mutual Sir Joe!!!!!

Will those Crites woofs sound weird crossed at 1200hz?

 

[laatsch55]

Don't know if you can. They're crossed at 400 due to the cabinet. You can check TS parameters by checking for a Klipsch K-33 woof.

 

[mlucitt]

They're crossed at 400 due to the cabinet.

Horns are wonderfully different animals.

Horns are wonderfully different animals.

Yes they are.....,bless they're hearts..

 

[mr_rye89]

Yeah the woofs are direct radiators on the Altecs so I can go a little higher.

Consensus seems to show the k33s roll off after 2000hz. That'll do.

Those Crites woofs look real nice for the price. My Altec 422-8z woofs are technically guitar speakers.......

 

[Skratch]

I have 515B Altec in my Voice of the Theaters, I also have a pair of 416A that I swapped out for the 515's. They are both rated less than 50 watt and are from the old tube amp era

I love hearing stories like that. Makes me go all squishy inside.

A childhood friends father had a pair of VOTTs hanging from chains in a vaulted ceiling great room.
I always admired them and they're probably one of the reasons I chose this as a hobby.
He had some little tube receiver to drive them.

I was screwed after I went to my first concert. Been chasing that rush the rest of my life...

 

[J!m]

Saw Rush many times.

Including R30 and R40.

 

[pennysdad]

I was screwed after I went to my first concert. Been chasing that rush the rest of my life...

... and that's why I became a Sound guy. That 'rush' almost every day of the week. Some of the biggest and best systems on the planet. Doesn't get better than that!

 

[laatsch55]

Amen George....I now I pay a lot more attention to the sound board folks and how soon they tame the venue. Pretty impressive...

I treat venues like giant pool tables.
The reflections are the same...
