Music My Tapped Rear Loaded Band Pass Horn! (A subwoofer!)

Just though I would share this, I've just finished glueing my first horn project together and I am testing it before it gets the sanding and paint treatment! I have to say it's awesome! Just testing with a 25W amp and not going full whack and it shakes the house and you can hear it a couple of houses away! This driver whould be handle 100W no problem in this enclosure. The enclosure is a bit longer than 19" cubed.

THIS is where I got the design.

Here's a few pics.

The driver used. Eminence Delta 12LF.

The internals.



Glued.







It sounds great too. Excuse the bad pic qualtiy good old iphone!

 

That's pretty dang cool!

Your keyboard however.. Unforgivable.

 

Those keyboards are awesome. Much better than those piano sized "gamer" keyboards.

 

Agreed I love this keyboard much better than others that are 20miles long like the G11!

 

Nifty box! I'm about to dive into my own box-building project (single 8" driver in a ported box), so it's rather encouraging to see someone else doing similar.

 

It's a nice little folded horn woofer

Although it looks very different, I agree Techno-Dann that a horn enclosure is similar to a typical ported box, where you can boost the output, but the response and power handling drop off sharply below the tuning frequency. Horns can boost the gain more than simple ports, but as with any enclosure, you trade off delay for gain.

Are you planning on using a single 8" as a subby Techno-Dann? If using a single driver, I'd much rather go for at least a 10" with an fs at least close to 30hz. Tt would be twice as good as an 8" with the important deep sub bass rumbles under ~40hz at any given power level, all for just a slightly larger size... but then again, you can say the same thing about moving up from 10" to 12"... and 12" is still pretty cheap

 

That is incredibly cool. I want one.

Actually with all the custom speaker projects going on around here lately, I've added a full set of custom cinema speakers and an amp to my "to build" list for 2011. One of these would compliment them quite nicely

 

Weirdly shaped buttons throw me off, and the one I have developed sticky keys.. My usual keyboard is perfectly sensible!

 

I use those keyboards for work. It annoys me, I like my G15 a lot more. Keystrokes are smooth and comfortable though.

I love subs, my car doesn't however, split my rear window and cracked a seal in the roof. Has continually leaked ever since.

Nice job on the enclosure.

 

Damn

Is the subby box so big that you had to cut metal out of the car so it would fit

 

I could make you for you at a good price!!

And thanks for all your other comments!

 

I'd love to hear that baby booming. I've got a couple old 10" sub speakers and they used to shake the house too. Not used em since I went bi-wired though.

 

Hmm... Now that you mention it, I've worked with some dual 15" subs that were absolutely beautiful - dead flat down to 20 hz...

The design as it sits (Single 8") has an fs of 42 and a -3 point of 32. Could be better, I agree, but kinda hard to find anything that'd go lower and not take up a huge amount of space. The box will be about the size of my case, it'd be a lot harder to hide 5 cubic feet of sub somewhere.

(edit) I suppose I should explain what I'm doing with the sub. I've got a pair of Tapco (Mackie's generic brand) studio monitors for my PC's mains, and they're great down to about 100 hz, where they start to fall off. I'm building this sub to fill in the gap below that and give me closer to full-range response for my PC, not for massive house-shaking bass for movies. One day, when I have a big-screen TV and space for subs, I plan on building something much bigger and much lower. (/edit)

 

You made a little scoop! Thats well nice. Dont think i have ever seen such a small scoop, what is the response like?

Which Tapco's? I used to have some S8's but then i switched from active monitors back to amp + speakers. I have a wharfedale powercube, 12" downfiring sub. is great, but doesnt play all that flat in the lows.

 

S5's, here - little bit more portable than the big S8.

 

Ahhh, they'll be pretty good for games, but seeing that you've enjoyed a pair of super smooth 15", you'll have a big itch that needs scratching when you play songs! If it's a small to medium room, at least get a pair of 8"...

or one 10".... you know you want to

 

Those are awesome when you hit concrete pillars with them. Button rain mayhem!!!



There is a video on youtube of a coworker smashing one, but I can't find it...

 

I used one of those keyboards to assault someone in school once. It's actually quite a sad story because that was around the time I got into a state of mental health that needed counselling, but damn, that guy wanted to use the computer I was logged into and kept turning the power switch off at the wall. There was a computer the other side of the room that kept crashing every 10 minutes that he said I could use, so I said he should use it if it's that frickin' good. And hit him with a keyboard.

It survived. There's worse keyboards around.

 

I wasn't a very big fan of all the keyboard hijacks in this thread, but your story is totally awesome

 

Oh but that would totally spoil the experience for me! I'd much rather have the awesome experience of making them myself
