Building my first set of speakers.

[Feebz]

Hello there,

I've been following the forum for a bit. I'm interested in making some Loud speakers, mainly for listening to music in my basement den (probably 10'x 20'). I'd like to keep the cost around $200. I listen to a lot of stuff, anything from jazz, to old r&b/soul, drum and bass, that kind of stuff. Size of the speaker is not an issue, will be driven by a denon avr-1802 (80 watts/channel). I don't have a subwoofer.

Any ideas on what kind of speaker would best suit me? Any plans out there? Any help would be greatly appreciated...if there's a 'recipe' out there for me please let me know.

Hope you can help,
Feebz

Take a look at this:

$67.00 total for parts, before shipping, and not including cabinets.

Hmm......

something that sounds half decent might be an idea :

Size of speakers is an issue. You trade off the bass you can get
withy big cabinets against the better midrange of smaller boxes.

i would have to give a second vote to this project.

if this is your first speaker building project, i feel its best to just get something under your belt before you try and accomplish anything really great. these speakers will sound alright. they will play music, and they just might have a decent amount of bass to them.

when i first saw the project, i thought "this would be perfect for the first-time speaker builder just looking for a cheap pair of speakers".

chances are, the speaker will cost much beyond the basic "bill of materials". so if you find a project that all the bits and parts cost $180 or whatever, you will spend $300 just on other miscellaneous parts to finish them.

start out with something simple and cheap, and see how it goes. if you like it, and like the results, then you can start moving on to something bigger and better with your new-found knowledge.

Thanks for the replies guys.
The partsexpress kit looks a bit too simple...I have couple sets of 'nice' speakers that I enjoy...Wharfdale, Speakercraft, some Polks....The speakercrafts are my favorite...I don't know the model, but I just enjoy their sound.
Would this kit be comparable, better? To be honest, I want to WOW myself with the speakers I build. Would the partsexpress do this?

I don't mind spending a little time and money for something that I'll really enjoy. The Lyra design looks interesting....looks like something I could do. i've also been considering these t-lines http://www.geocities.com/bunkie21/frontview.html

Would this be suitable for the type of music i listen to?

Sorry, I'm a total freshie when it comes to speaker design, just looking for the best possible design, if it works out well who knows what this'll lead to.


Any ideas?

Hmmm......

The goldenboys seem to have no baffle step and a massive bass peak.

The alternative bass driver should be a better idea, but this still
has a high Qts of 1.44 compared to the almost joke value of 2.1
for the Buyout driver.

The SPL level for the speaker (85dB/W) is pathetic for its size.

The treble quality of piezo's is a joke compared to a decent dome.



I stand by my original post, the GB is not a hifi speaker.
(but with the other bass unit, better than most lash-ups)

I built the Murphy vifa tower, mentioned above, over Christmas for a friend of mine. I must say that I was very pleasantly surprised with the result. I was very tempted to keep them for myself!

Hi,

the T-line cabinet looks OK but there not much design in the rest
of the speaker. Always go for something that the designer has
measured and can show works well. The Bunkie21 for a start
has no baffle step compensation, enough reason to discount it.

Hi,

note the Lyra could be converted into a reflex floorstander,
or with some help from this forum a floorstanding T-line.

Hmm, what exactly does that graph mean?
Looks like I'll try and go with the Vifa design.
Thanks for all the input guys!
