You're gonna love this.... Greek Column Sonosub!

[chasw98]

Nope just thinking you could revolutionize the SAF/WAF issue with the concept (it is a very clever idea.... :T ). So just trying to help you get your 15 min of fame....:wink:

I've already had my 15 minutes, long time ago, far, far, away. But you do raise the idea of the possibility of putting these subs into designer components that would normally be found in a home. I mean, I have seen them built into coffee tables, end tables, chest of drawers, etc. If we really thought about it there are probably some other "home" items that could be disguised as a sub and yet pleasing to the SAF/WAF side. Think about a brick outdoor BBQ with 4 18 inch drivers and a few thousand watts in the back yard.... No problem with reflections :T

[steve nn]

I've read that poor self esteem causes this issue.

Oh dear, I'm in trouble for sure.. that's a 12.5' ceiling. I made a few calls and no counselor that I got in touch with would take on a bass head (no hope)..of course I was searching for you Chuck. :P

[SteveCallas]

Giggity giggity giggity :lol:

[chasw98]

We may be good people, but we have a little bit of sickness. She has decided to go with the fancy capital I posted a few answers back. She was very excited and jumping up and down over it.

Steve nn, you're welcome to lay down on the virtual couch and spill your problems anytime!

SteveC, giggity giggity giggity. I don't know. You need to get that house and those other monsters built.

What is it about "Steve" and bass. Is there a correlation? I need a government grant to explore this phenomenon.

[SteveCallas]

You need to get that house and those other monsters built.

Getting the monsters built is no problem - getting a decent house....a bit tougher :B Back in Lafayette, you could get a good house for $175. Here in St. Louis, I'm looking at $210 minimum just for something decent. I think I'm making good money for my age, but the idea of taking a big loan and paying so much in interest over the years doesn't interest me too much. I'm patient though - the Three Amigos will unite one day to form a trifecta of limitless bass capability.

Try it down here in Florida. Mine was 275, has risen to 350, and is really just a 150! Go figure real estate.

[BobEllis]

Aww, Qwitcherwhining! 350 might get you into a single family house near here, but do you want decent schools with that? 210 won't get you a 900 square foot condo. There are lots of places worse, too. There seems to be a pretty direct correlation between where you might like to live and cost of housing. Go figure.

[soho54]

$210?!? A month? With A/C and no roaches? Where was that again? Here $450 will get you A/C, and $600 will get rid of the roaches. My 900 sqft duplex is $750! You've got to be talking weekly, right?

[soho54]

maybe $210,000 ?

[joecarrow]

well, if we're talking about real estate...

I think they're leaving off about three zeros. I just moved out of a 600 square foot condo in Berkeley, CA that the owner was trying to sell for $375,000. You want a back yard in the San Francisco bay area? The average price of a house in SF county is $875,000, and the cheapest county in the area (Solano, I believe) averages $450,000.

I can't wait to get out of this area and get a garage! I envy you guys with your $200,000 houses.

Lol, my apartment is $750 as well, but I was talking $210,000, and that is at the southern outskirts of the city for 15+ year old homes. If I moved closer in or looked to west of St. Louis, which is the more upscale area, things really start getting ridiculous. 210 is the bare minimum I'm looking at paying, and being one year out of college, it's not too enticing.

No offense, but someone would have to be paying me to get me to live in California :B

Ditto for Vancouver. In the past 10 years prices have doubled, tripled, and quadrupled in some cases. :E Doesn't help that we're hosting the 2010 Winter Olympics in four years. Not a good time for potential first time home owners such as myself. Definately a seller's market these days.

I don't know. Firt time home owners in the states can get some incredible financing. Then you turn the house in 3 or 4 years and walk away with a healthy down payment for the place you really want and can afford.

Yes, a garage is nirvana! 3 & 4 car garages are really heaven sent! A barn out back would be incredible, too.

About 10 years ago, when I lived in Aspen, CO. the bottom line price of a home was at 1 million dollars. Then the city realized that no one who had to work could live near their so they started employee housing projects where you could get a 2 bedroom condo for around 300,000. Try being a waiter or waitress and making those payments. Why it would be hard to afford a sonosub at those prices!

[JoshK]

Here $400K will get you a 400-500sqft 1 bedroom condo at the very most. Houses start around $600K and that is in a dicey neighborhood.

[SteveCallas]

Geez, I hope you guys are all making 150+ a year.

[chasw98]

And on the subject of Greek columns..... This capital will cost $440.70, take a 3 week lead time, shipping is extra, and ,get this, weigh 170 pounds. The good news is that there is a 9 inch diameter hole in the center. The measurement at the top is approx. 30 3/4" square. They recommend a 27" square base.



I hope a 16 inch sonotube will hold up a 170 pound load on top of it. Needs some more investigation, I think.

Cast plaster is heavy. Might continue shopping to see if you can find some made with structural foam. Much lower weigh and significantly lower cost.

Remember the ID/OD thing with regard to the tube and the opening in the capitals

[JonW]

Chuck-

Interesting project. For what it's worth...


I'm going to guess that having one column sub is going to look a bit odd, when actually placed in the room. These things tend to look _much_ better in pairs. So that leads to the idea of either making one column sub and one dummy sub to match. OR: Two smaller, matching subs to get the same output as one big one. That could help with the weight of some of the tops you're finding, if there are smaller versions available.



And I have to say: This is now officially the most mature discussion board on the entire web. Chuck posts a picture of this lady and not a single comment in response. :T

Thats why I think she will end up with a second full size column in her room. She already has 2 columns in the room.
Either the most mature or we all just hide out and gaze.....

I agree. I need to find a lighter weight solution. Money is not really the object here. She was very happy to pay for what I found so far here, but I just have this price/performance thing in my genes that makes me search all possibilities. I did learn that when you buy a capital that says 16 inch for a tapered column, it is really 14 inches at the base. I was told I needed an 18 inch capital to fit on top of a 16 inch sonotube. The goods news is that they have a 9 inch circle cut in the center that will accomadate a 6 inch port quite nicely. Thanks, Thomas

[w8liftr]

Chuck, I have seen those made of cast foam before, like ThomasW said, much lower weight and cost. I'll check a few sources around here and let you know if anything turns up.

Oh, yeah!!!! Check this out (picture me dancing!).

And guess where they are located?

3510 N.W. 53rd Street

Fort Lauderdale, Florida 33309

They are less than 5 miles from house!

[w8liftr]

Cool.

[SteveCallas]

They are less than 5 miles from house!

It's a small world

[JonW]

Sounds good. One lone column would look odd. Having that second one should help the asthetics, I'd think.

They are less than 5 miles from house!

And they say that Florida has no culture. Hah! Foam reproductions of ancient Greece. How can that not be called culture?! :P

Either the most mature or we all just hide out and gaze.....

Yeah, or we're just getting too old and slow for such things... :unsure: :P

[chasw98]

Florida has culture. Their biggest request is to paint faux columns in a coral color!

I will be too old when I get too slow for such things 8O

[JonW]

I guess it would be a "fusion" culture combining the local Florida coral with a nod to the ancient Greeks, then sprinkled atop with good ol' American synthetic, petroleum-based materials. :B



And thinking more about the broader implications of your project here...
This could work for so many more clients and audiences... I see subs for many different people:

-Make it a square column, with a pointy top, like the Washington Monument, for history buffs.

-A rounded top sonosub with aluminum sheeting around, looking like a grain silo, for the farmers in need of deep bass.

-Put fins around the lower part of a sonosub and a cone on top, for the NASA rockets scientists.

-Cover one in bark, have branches sticking out the sides, for the more eco-minded bass lovers. Or just people who like large house plants.

You get the idea.

[chasw98]

Here is what FedEx did to my RL-p15 driver. It went from SS outside of Los Angeles to Orlando, Florida, then back to Los Angeles, and finally to South Florida. It took approx. 10 days for all this. Then I open it up........ 8O 8O

[WillyD]

Oh the HORROR! :E

And people complain about UPS.

[derekbannatyne]

Wow how does that even happen?

[ThomasW]

Yikes, looks like it was dropped off the conveyer belt at the sorting facility. Or thrown out of the back of the delivery truck.

Over the years I've had more significantly problems with FedEx than UPS ...FedEx Ground consists primarily of subcontractors and isn't nearly as good as regular FedEx.

[BigJim_inFLA]

That's enough to make a grown man cry...and smack the FedEx guy on his next trip.

[palmtree]

Yep, I'm gonna use the tried and true classic of the moment. RL-p15 D2, EP2500, BFD. Can you check my modeling for 7.75 cu feet in a 16 inch tube and 35 inch port length, 6 inch diameter for a 16 Hz tune? Thanks.

will you wire the EP2500 so it sees 2 Ohms on each channel? That is a lot of power.

[chasw98]

Unfortunantly, Mike was out of D2's so I got a D4. I will run 4 ohms on each channel. I currently run my D4 wired in parallel so that the amp sees a single channel of 2 ohms and have had no problems. The other channel on the amp drives a pair of rear surround speakers in parallel for an impedance to the amp of 4 ohms (2 8 ohm speakers). HTH

Chuck

[Carl V]

how was it pkg'd from the mfg'r? I've had a few Tumults
shipped from around the country...bolted to a wood baffle
and then 4-2x2 braces connecting to another 18" baffles.
The boxes take some abuse but damn the drivers are always
fine. Two Aurasound-18s were likewise well boxed yet mishandled
by Fed-ex. Bax Global is the way to go for big items or heavy
expensive items.

Sorry to hear about your misadventure. 8O

[chasw98]

It came in a heavy duty cardboard box with a cardboard ring around the magnet structure and a cardboard ring around the "throat" where the magnet structure meets the frame. That cardboard ring is reinforced against the edges of the box. It seems flimsy now that I had one that broke, but it got thrown around a lot.

Chuck

So the EP2500 has no problems continuously running a 2 Ohm load? I am trying to decide if I should get the dual 2 or the dual 4 RL-p15 to run off an EP1500.

[ThomasW]

A 4 ohm load is a always a better idea than a 2 ohm load.

[palmtree]

Maybe I should start a new thread so I don't clutter up this one with my OT questions.
Thanks

[chasw98]

Here is the beginning of the end. I have "mocked" up the base of the column to see how it will appear visually.


My first thoughts are to remake the doughnut around the sonotube and make it 1 1/2" tall with a 3/4 roundover on it as opposed to the 3/4" tall with a 3/8 roundover as shown. There will be a base plate that is 24" square for the bottom. The square angled section is 22" square. I should be getting the capitol on Friday.

[nick77]

That looks great Chas, I think you can go to production with this one. Hehe :B

[BobEllis]

Chas, I agree that the ring around the base should be more substantial. I also think that the corner posts (providing the air space) should be at least 2-3 times as thick as those in your mock up to provide visual balance. The big heavy looking column should have substantial "feet".

I'm just a big heavy guy that likes big heavy things, so what do I know? Very Cool idea.

[SteveCallas]

I agree with what has been said so far, and I think it would look nice to make the legs fancy, maybe something like this Q-leg 1?

Image not available

Also, I'd bet that small air space (3"?) between the driver and base plate will at least partially load the driver.

[chasw98]

Actually, in the end the legs will not be visible. I am going to make velcro removable grilles that will go on all 4 sides to give the impression that the base is solid. The legs are 4 1/2 inches tall and will be sitting on a removable base (driver access) that will be 24 inches square. The grilles will be covered with cloth that will match the paint job the lady is going to have put on the column. BTW, the capitol is ready for me to pick up and I should get it today.

I do agree with Bob's comment that the "doughnut" needs to be beefier. More work!

[SteveCallas]

I gotcha. On a hunch, let me know if the air displacement by the driver can "un velcro" any of the velco connection with demanding material when its done :B Probably won't, but that would be something if it did.
