Full-range for dummies...

[Francesco]

Hi all, I'd like to build a couple of loudspeakers (or try, at least) and I was thinking about fullrange, they seem the simplest way to enter the DIY world.

I'd like to have a floorstander loudspeaker, with some decent bass extension, so I guess that a vented box is the way to go.

Can I use more than one driver?

Can you guys help me to start?

Thanks!

Ciao

I would start with Cyburgs Needle...not expensive and you can see, what's possible

Cyburgs-Needle for Tangband W3-871S

[Francesco]

Is there something... ehm... bigger?
With 80mm ø - 82db SPL - low freq @ 130hz it seems a little small to me... maybe I'm missing something

[larkinrulez]

Would be just to get into it....with the Tangbands you get 50hz.
Of course it's not a very loud box but you will love them and build then something bigger, with the Needle as reference!

Can you build more complicated box? And as the size is no problem ... 6.5 or 8" fullrange driver would do it for you.

Check out Fostex FE-166/167e and FE-206/207e

Hi,

the easiest way is a well designed and documented system :

How about starting with some basics: system, listening habits, budget. What amplifier do you plan to use? What sort of music do you listen to? How much space do you have, and how much money do you have to spend? MLTL's, folded pipes and the like pose some real advantages over simple BR's (especially with fullrangers) and they are no harder to build. Here are some sites to get you thinking.

Many here advocate MLTL's like this:

Dave's site has a ton of ideas, some very simple:

One of the BIB's may fit you (especially if you want bass from a fullranger):

I'm very partial to the Hemp Acoustics drivers, but it'll be a month at least before you can get the new line. Patience is required.

There are a multitude of options that will be difficult to sort through unless you can nail down some criterea. I'm a firm believer that you should also pick a speaker and enclosure that you like the idea of. If everybody tells you (meaningless example, both would be great) that a BIB with the Fostex FF165K is absolutely perfect for you but you really really like the look and idea of the CSS FR125 in a Fonken, you should build the latter. You'll be happier with something you truly want. If you are completely open to all suggestions, then your requirements can dictate the best solution. And finally, there are strong advantages to going with the largest thing you can tolerate.


good luck,

pj

would the cyburg's needle also work with the RS 40=1197? i am trying to come up with a plan that a total neophyte wood chopper would be able to handle. not looking for the last word, just something to 'see if i can do it' and run with a little tripath amp or small tube amp. but, as much bass as can be develped. i already have the drivers...

[pjanda1]

Why not do something designed for the 40-1197? For "as much bass as can be developed" and an easy build, do the BIBs. Also look at the ZigmaHornet ML-TL and GM's ML-Voigt on Planet10's site. Click on the link from my previos post, then click on Fostex. Unlike the BIB's, I think they'll require some BSC, which will hurt efficiency wiht your little amp. You'll see 'em when you scroll down.
