Model for fun: Revamped PC 'Bass-Toaster'!!!

[Wolf]

I wondered when PE would get these in stock, and I thought I'd model for fun... http://www.parts-express.com/pe/show...number=264-909

If you'll look closely, it's a 'dual-surround' driver. There is no actual spider, and the second surround does that preempted duty.



Now for some fun. There was a sales flyer a few years back with a 'bass-toaster' advertised. Thought it'd be fun to try something in that vein.

The driver exceeds Xmax at 43 Hz in the Vented design, and 48 Hz in the BP design, both at 25W input power. (The '-BP' Att#3 attachment has a dual-flared port.)

Just thought I'd share!

Cool. What about four of them?

Then you might as well buy the W6-1139 for the reduced price of ~$100. You get more performance, and the same size box as a quad of the little guys.

The Toasters really only apply to the PC 2.1 system, as anywhere else they may overload trying to dig lower and louder.

The 2 foot long port in the vented model might be interesting to incorporate

Dude, it's only 1 foot... not 2. ;)

I see... Then it is time to coil it up in a 6 liter enclosure

In all seriousness, for $30 I think I would buy a Dayton DVC instead. Even in a small, sealed enclosure it will match this little guy.

For $22, i'd get a 12" Car Audio Sub:

I'd then measure it, and build a box for it. Chances are you'll get better output with this 12. And its cheaper than the 3" tb driver.

Yeah, thats right, a car audio subwoofer.
Because it will have higher power handling, you can EQ the hell out of it, using the PC as the EQ.
P.S - The 12 has a spider.

Also, The Dayton 7" Reference Driver is only $37 right now.

Same FS range,more xmax, More Sensitivity, Better power handling, More surface Area, A phase plug, and a spider.

But if one needs a SMALL enclosure for bass extension (small office) then this is the way to go. My Stormy's need to have the bass filled in (per comments from the judges at 2011 MWAF) and building a matching enclosure (3 liters) will be no problem.

Aww c'mon people its called nostalgia, think outside the box a little! This thing is COOL!! Dual powered subs on your desktop would be sweet...

Re: Model for fun: Revamped PC 'Bass-Toaster'!!!

According to everything I've read about spiders, the design of the TB driver (which uses another half-roll surround at the back instead of a spider, so it's not like the coil is un-supported) should be superior, because spiders are subject to more manufacturing variation than surrounds typically are.

Thanks, George- Does that mean you're building one? ;)

Matt- Yeah- I knew this would be beat about a bit in regard to price, but you can't beat the form-factor. I agree that it would be very cool on your desktop. Maybe this is a job for the KEMO amps from MCM? Small form factor, and 18W...

Tater- Yep- I think you have a point there.

Re: Model for fun: Revamped PC 'Bass-Toaster'!!!

So the ported version comes to about a 12" long port about 1 1/4" Inner Diameter?

I'm having trouble converting the liters to cu. in. It looks like about a 6" cube?

My calculator skills is a little rusty! :o

Maybe the SA25 sub amp would work well with this. It's about 6 1/4" x 6 1/4" I think it's only running $34 right now. That plus the $30 for the driver... $64 for a mini powered sub sounds like a fun project to use up some scrap wood!

Re: Model for fun: Revamped PC 'Bass-Toaster'!!!

Wolf - Yes oh great alpha pack leader. 3 liters is the EXACT volume of the spheres I built for the Stormy's. Even have an idea on placing the 12 inch port tube. Now they will have the bass extension they lacked. May even change the Stormys to sealed instead of vented.

It is added to the project list behind the Sophomores, a MTM with Peerless buyouts that is to be yet designed and a center channel design for one of my daughters. So little to do, so much time. NO, strike that. So much to do, so little time.:eek:

May try to get it built for the CKYDIY this fall as it should be a quick build except for turning the wood spacer ring that goes between the Ikea bowls.

Re: Model for fun: Revamped PC 'Bass-Toaster'!!!

You guys crack me up!!! :D:D

Yes- that 3 ltrs would be about an internal 6" cube.
Once you place the driver and the damping in there, the 5.7" internal cube will/should equal a 6" cube. 12 1/8" long by 1.25" diameter port.

I'm curious what you guys will come up with visually....
Let me remind you the 25W amp is a little much I would presume for this driver going all-out, but it should be usable for that project. I would isolate the amp in the ideal situation, but you may be able to get away from that.

I did the bandpass model because more output potential in a minimal box could prove acceptable in more applications.

What version you building, George?
