Hello!

It seems our DIY gurus are reluctant to share their expertise and provide a diy speaker project as I've requested in my previous post.

Anyway, thanks guys!

guys can you help me out from where can I find a "quality" adhesive vinyl for my speaker project.
(other than "ACE hardware")

Hi!

It's not that DIYers (including me) here don't want to share info but building a speaker project is a bit complicated (tampo ka naman agad eh

). Choices of drivers, box configs, and even materials differes from one constructor to another.

I myself only use local drivers (dai-ichi, crown, etc) and make the most out of them. But if you have access to better sounding drivers then that's better. Tell what you have and maybe I can help you.

hi DIY Gurus---

Ive seen speaker boxes of different sizes on sale in DEECO... but m just wondering because these are plain boxes-- should i try a DIY speaker, should I still need to put some FOAM or damping materials inside these boxes ?

timn8ter · « **Reply #75 on:** Aug 09, 2004 at 02:22 PM »

It's not a good idea to start with the box and try to find drivers to match. You should always start with the driver first then design the box (and crossover if necessary) to accomodate the driver.

getafix · « **Reply #76 on:** Aug 09, 2004 at 02:48 PM »

I agree with timn8ter... better start with the driver and not the other way around

Haven't read all of it through, but seems like some insights on system building can be had from here:

I completely agree with those who agree on what they agree on.

better start from the ground up, obtain some drivers and start from there, it sure helps if you have their specs.

all seem to agree with tim and thnks for the comments -- so does it mean that i have to ask first from the store the appropriate set of drivers and tweeters for a particular box that i want there?

what ihave in mind kasi is to buy a box, a set of 50 w 6" mid bass and a tweeter that would fit on my desired box and a crossover and ill just be the one to solder the connections==

more advise please---

and thnks again

The problem with that is you wouldn't know how the drivers will respond for the said enclosure. Its really not easy as getting an enclosure and get drivers that fit it..it might work but it might not. I am just speaking from personal experience so your mileage may vary

Your lucky if the sales person knows the recommended drivers for the box.

JojoD818 · « **Reply #84 on:** Aug 10, 2004 at 04:14 PM »

Sorry, too quick on the trigger...

Even if you do find the correct drivers for a particular box, how sure are you that the available crossovers have the correct crossover points for the drivers? Answer is no. So it would be a painful trial and error for you if you go this route.

timn8ter · « **Reply #85 on:** Aug 10, 2004 at 04:21 PM »

If you have never designed a speaker before I highly recommend that you use someone else's proven design. If you can acquire a complete kit that's even better. The typical process for designing a speaker involves setting a budget, deciding what the best basic application would be (bookshelf, floorstanding, etc.), choosing the appropriate drivers, designing an enclosure based on the mechanical and electrical measurements (Theil/Small parameters) of the drivers, designing a crossover, building a prototype, then measuring and adjusting before building the final product.

jerix · « **Reply #86 on:** Aug 10, 2004 at 04:43 PM »

At this early, it seems that good reactions are pouring in -- i appreciate all the insights AMIGOS!! --;) but others can still share...

for an uninitiated but very curious and adventurous individual like me, i really could go this painful direction and face the possible consequences of the dangerous trial and error -- I wish the experts here can supply this thread more accounts of their speaker project--

Sometimes making your own speaker might cost heavy...more expensive than branded ones. We have shelled out a lot of money and frustrations for experimentation but no amount can replace a good and rewarding outcome.

Cheers!

A fellow I know shared this with me.
"A friend was visiting my wife and asked about the speakers I build. She answered, "Yes, Ed has spent thousands of dollars to build cheap speakers."
