Open baffle subwoofer

[StimpyWan]

And I don't think you understand.

I am a full time college student, who works 30 hours a week.

I make $700 a month, pay $620/month for college, $100 a month for insurance, and $100 for gas.

The only way I'm able to pay the difference that I otherwise would not be able to afford is because I had some money from my High school graduation party. I have no time, or money. Im luck if I get to listen to my speakers 3 times a week.

I will have no time, or money for the next 2 months. After that I can buy some wood and tools.

After I finish my guitar build of course.

Until late october I will be barley scraping by. and any spare money is saved in case of any unforeseen expenses.

Hey, I know how you feel. Money can be very tight at times. The important things come first. Toys second. But, it's nice to dream about what could be, because when circumstances change for the better, in the near future, the dreams can then become reality.

For now, you've received a lot of good advise. Study what's been provided. Also, do a Google Image search on OB Speakers, and OB Subs, and you'll find many, many projects that you could emulate, if desired. Plan what you want to try, when you can. Try multiple designs, and narrow down the better versions to a final speaker, that suits your needs. Then enjoy what you have, regardless of other opinions. And you don't have to defend that to anyone, because it's what you like. It's as simple as that.

Check around your locale to see if there are any recycling centers such as HABITAT FOR HUMANITY, they sell all kinds of building scrap for dirt cheap. It would be perfect for prototypes and temporary baffles until you can afford some fine baltic birch plywood, also consider trying MDF aka medium density fiberboard, it's pretty inexpensive and easy to paint. Habitat For Humanity also sells used tools and some nice deals can be found there. If your college has any kind of vocational program or arts program you may be able to find some help there with the woodwork.

got one right here in elgin. Fantastic!

Ill check them out once Im done paying back my dad for the the last pair of the Zenith 49cz852 drivers. I found another pair on eBay that were absolutely flawless all-around but they are $230 with shipping, ouch. I didn't have the money and my dad loves these as well so he said he'd buy them and I pay him back.

Hey, they'd only be $225 for me! I should go for it. Seriously, after hearing your descriptions of their sound quality, I am curious. So, if I can find a pair at a decent price, I'll definitely give 'em a try.

Thanks for the tip on these too.

There is one on eBay right now but there is some weird stain running down the speaker. I was able to snatch my last pair for $120. the price just keeps going up. Occasionally there is one person who sells a pair and does not do their research and has no idea how much they are worth. They are all worth the money though and pair well with a $5 tweeter from parts express.

I stopped reading here. Do you want to learn about science and fact, or do you want to speak about voodoo? If you want to talk about voodoo, there is a special forum for that.

I really doubt (but just a guess), if he is talking about cables, that he understand what hifi actually is. Which is ok.

Lots of high end gear sounds. As in, its not "flat", but sounded so audiophile people like the "air", the "revealing", the "black", the body. Its all .... Fuel magnets and chrome exhaust tips.


Why don't you build your OBs first, then wory about sub? And no, you don't need an OB sub. Infinity baffle? Yes, if you have the room. But then you could build a bass horn.

Tube amp and subwoofer. It simply doesn't make sense man. I understand some people like tube distortion. Its cool, I like dreamy movies too. It certainly isn't "hifi".


If you want the science side, as in building speakers and measuring stuff ... start here:

Watch the first presentation from the woman.

Completely off-topic but I went to High School with that girl (Poppy). Small world.

Have you tried listening to headfones while using a subwoofer? Epic.

Sounds interesting.

The headphones I posted about will make you swear there is a subwoofer in the room. They really are amazing. For the price, I am sure you all don't believe me, but seriously they blew me away.

BTW, a jigsaw can cut circles, and do it well. Just drill a hole to start it with and be careful. If we are talking about doing a cheap test baffle, scrap wood is good, OSB is good, even cardboard is OK. If you have vibration issues with the cardboard, you can even dampen it.

Whether or not you like tubes or not is your opinion, and guess what? theres a separate thread for that. I don't know what tube amps you have listened to but the ones I listened to sound incredible. It adds texture to sound in a good way. What erwin has taught me is that you shouldn't listen to anyone else. Just try it, and if it sounds better to you then do it. No one over the internet can tell you how your system sounds.

YEAH... take that.

Open baffle? If you`re after clean strong bass..

I've been following the exploits of our young Mr. Parkin off and on of late. I, for one admire his enthusiasm. Granted at times this enthusiasm may cloud some of his reasoning but so what? I can't understand some of the rather rude comments thrown his way. Give the kid a break. I remember being a young college student full of grand ideas, convinced I was on the right track to solving every problem that presented itself. I was also dead broke most times. Just a part of being a student. So cut Nick some slack. Help him learn instead of chastising him for his naïve mistakes. Part of what, in the past anyway, made AK a cut above other audio forums was that everyone was welcomed to their own ideas. Reading some of Nicks threads make me wonder what has happened around here.

I wish someone would have talked to me in realistic tones about how I have no clue, am not the smartest dude in the world, and so on and so forth.

He can't cut a hole for a tweeter unless he has baltic birch wood and a makita router...

"Extended spatial sound field" sounds like advertising speak to me. I'm willing to give those Senn's a listen. As for now I'll stick with what I posted.

I've gotten used to hearing a soundstage. It started in 1976 when I bought my first pair of planars (Magnepan MG-1's).

At least Senny is honest enough to call it an "extended sound field", not soundstage.

Ahh ok, Lots of reviews on headphones use that term.

Wouldn't headphones just have a much closer soundstage, like having your speakers right infant of your ears?

It makes sense though. Speakers have a soundstage since they are quite literally "over there" whereas headphones are right next to your ears.

I told myself to let you be, but once again you shoot yourself into your foot. Reviews. Don't read reviews. They all just repeat themselves, calling things grand and awesome and reciting worthless specs like "frequency response from 5 to 22 KHz" Of course they use words like soundstage and "air" "fullness" and all of the other virtual "credentials" they place on things using words that don't make any sense unles one is young, dumb, or doesn't care.

A soundstage has height and depth and "wideness". In headphones height and depth are simply missing.

Yea really, surprises me sometimes too. Cool!!!

You could always mount the woofer in a wall with the rear output directed at the neighbors. A true infinite baffle with no loading on the cone. but with those long wavelengths the destructive interference between the rear wave and the front wave will be horrendous, if the rear wave is kept in the same room.

These Zenith drivers have been quite the rage for some time now. Hence the supply is going down as demand goes up. Not a good thing for hobbyists. I should have bought some when they were cheap because I won't spend anywhere close to $200 for them. That's not to say they're not worth it. By all reports they really are excellent sounding speakers. I'm moving away from OBs and will be selling mine. Probably a mistake but I want to try some other things. Being retired sucks as far as having extra money for audio toys. So I sell in order to buy. Good luck finding a pair, I'll let you know if I see a good pair.

Thanks for the advise. I figured that demand was increasing for these, with ever escalating pricing. That's how it always works. But, I have enough spare drivers to build an OB toy, if I want. Though, that would be well down the line of waiting projects! My AR90 recap and refurb is most pressing, then maybe a custom AR90C center speaker, then maybe a line array, and a few other recaps, then...we'll see...!
