Any project starts by putting down on paper your requirements and goals. At a minimum, you want to start with:

1. Frequency range
2. SPL required
3. Mono or stereo
4. Desired size and weight
5. Cost
6. Location with respect to "main" speakers
7. Passive or active crossover

The requirements are:

1. Frequency range___20-120Hz
2. SPL required____???(I'm roockie)
3. Mono or stereo_____ Stereo
4. Desired size and weight___ no problem about that
5. Cost_____ less then $1000
6. Location with respect to "main" speakers___any
7. Passive or active crossover____ACTIVE

Thanks,
Cristiano

You may want to check out the Shiva woofers at Avatar Audio. Their white paper is a good introduction and provides a lot of design options. I'd recommend, for a rookie, sticking with closed-box systems; tuning ported and PR systems without the use of good quality impedance measuring equipment and a firm handle on what you're doing is dicey at best.

And use built-in plate amps. For this frequency range, you don't need anything fancy, just lots of power and reasonably low distortion.

They now are called Adire Audio.

Navin, TG3 and Ppfred,

I visited the 3 sites and I have now a lot of information to study.
I think I will do everything on my own.

Many, Many thanks,

Cristiano
