reloading some speaker cabinets

That's correct...you don't need to have a fundamental knowledge of how something works to enjoy it. However, not having that fundamental knowledge prevents you from making informed statements about it //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Just because I'm curious...what did you listen to? Did you find out what tubes it used? Push pull or single ended? With what speakers?

now now boys....

Heh. Why not talk about things you actually know something about?

That's an example of a line array. A whole bunch of speakers connected together - so it's extremely efficient and has a ton of displacement. Very good vertical dispersion, but the off-axis response to the sides isn't that great. Doesn't take much power to get one of these loud...

this looks like it would be way out of my price range, unless i can get speakers to put in it for 10$ apeice i think its a bit much. but if i had money growing on trees then i would be all about messing with that. it looks very interesting...and impressive:yumyum:

line array perhaps?

these are my kind of price range.

20 of them maybye?

i realise that they are very crappy speakers...but would it be a fun thing to experment with or a waste of my 20$

i scetched this in autocad: 20-4 inchers and a horn tweeter

do you have any links about wiring/building line arrays? youve got me fascinated.

What do you know of harmonics, solid-state boy...

Umm I'll take a blend and compromise between Harmonics/price/convenience.

Unless I win the lottery, then it will just be balls to the wall //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

theres some links around. thylantr has a tutorial on making a phase plug. blows away regular NSBs in tests (NSB is that driver u specified, they are used tor lots of shit). i also clear lacquered the cones on mine (just bought 10) and they walk over the stock coned ones.

which driver? this one:

http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=269-570

is that a "yes" they would be cool to make a line array with, especially if you laquer the cones: i think i might buy a grip of them and then spend a while building some/a cabinet(s) for em' if so-- especially at .49 per speak

At that price, they are definitely worth it just for experimenting and learning with. 16 of those in each cabinet in a combination of series/paralell arrangments would yield 8ohm with 80 watt theoretic power handling. hmmmm

my thoughts exactally.... but i need help with wiring. i was going to do 20 speaks, but that wouldent allow the proper load right?

what about a tweeter? what about the bass frequencies?

im physced about this!!

For a tweeter, just use a normal one...run a simple crossover to it. People generally use ribbons in line arrays because of the improved vertical dispersion, but like those Bottlehead Straight 8's I showed earlier, regular tweets work as well.

Subbass is the job of an external subwoofer //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

cool.if i dont have a sub at the moment, will it sound noticibly bass-less?

two tweets or one? could i still go horn if i wanted or is it still advised against? what should the power handling on the tweet(s) be?

It'll probably lack a lot of low bass response, yes...

If you want to talk to someone that's put a ton of time into making a setup like this sound good, thylantyr is the guy you want to talk to //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

He's on here sometimes, as well as CAF...

 

[brandontw 10+ year member]

hmm ok ...but before i let you go should i use 16 instead of 20? it would make the wiring a bit easier.

How about building this line array and using a PR downfiring or rear firing attached to the cabinet to extend the low end? Would that help out or just add too much complexity?

Also, where would you add the ribbon tweeter? Middle? Top? More than one?

As far as wiring 16, you just make 4 groups of 4. The 4 drivers in each group will be wired paralell. Then you attach each group in series to get a final 8ohm load. I think 16 in each cabinet will be easier than 20.

good stuff. yes i would do 16 in a huge series parallel setup as well
