The BLACK HOLE Subwoofer (2 Viewers)

[ChrisA]

Your not intruding on my thread at all. Any driver or product which can push the envelope of performance is what we are here for...

I have to admit I am quite content with the performance of the Black Hole Subwoofers until I can actually build a room/house from the ground up.

More later...

No Doubt!

You've got probably the baddest ported bass setup in known space! Extremely impressive. I doubt you'll be yawning over it any time soon.

I've been giving some thought to room structure, too. To cancel the significant newtonian forces my drivers will doubtlessly create, I'll probably recommend a force-cancelling bipole config, equaling about 1 cubic foot of displacment per cycle in a two-driver sealed alignment. With that kind of displacement, you'd better think twice about your home before you have your friends over for a demo of 8 Hz sine waves. The drivers will certainly have to come with an appropriate disclaimer of liability for damage to home and belongings.

Or, at the very least, to your pants.

For the sake of thoroughness, I guess I'll have the lawyer pencil that in too. Puts me in mind of a name for the driver. Big power names are a dime a dozen, and mostly taken anyway. How about Mr. Poopy Pants?

 

[Jack Gilvey]

Maybe something sophisticated like "La Manure", or a little alliteration to entertain the car crowd: "Fagal's Fecal Fountain".

Thanks, I'll be here all week.

 

[Bill Fagal]

Jack,
You've obviously given this some thought (and I appreciate it) but I'm not sure I'm too keen on a product that juxtaposes my surname with "fecal fountain."
Unless it would REALLY sell, that is.

 

[Jack Gilvey]

I'm here for you.

 

[Bill Fagal]

By the way, since I'm already talking about my projects here, I'll also mention that I'm planning a passive radiator. Since this suspension topology is so scalable, (motor Xmag is the limiting factor), I'm thinking of prototyping a PR with perhaps 100mm of one-way Xsus. It will share components with the active driver, so its Sd will be the same at about 1090 cm^2. It should also be mass-loadable up to maybe 6+ pounds--I'll have to see what kind of a beating it can take.

Now you're talking, Bill. God help the cat that wanders by during the pod race. Whack.

 

[Bill Fagal]

Jack,

You've cut to the quick of a real concern of mine: How do you keep walking furniture, passing cats, and curious fingers away from the *WHACK* zone? Trying to avoid an ugly mesh box, I've thought of putting a couple bars over the excursion zone, but if you get a finger caught between the bar and diaphragm during a 10Hz transient, that could be even worse.

Don't know exactly what to do...

Ah, just let them get whacked once. Won't happend again after that :p)

Don't worry about anything, making an appropriate
grill guard is certainly the easy part...

Isn't it just too cool when a sub designer's biggest concern is how to protect people, animals and furniture from the effects of his driver's performance?
