PC Fullrange Speaker - Any ideas? (Off Topic)

by soundcheck @, Germany, Monday, October 30, 2006, 15:17 (4101 days ago)

Hi Bert and others.

It has been a long time that I am starting a speaker thread.
The last one were my Ripoles if I recall it right.

Now -- the subject:

I plan to build a nice fullrange speaker for my office.

I'll use the T-Amp, directly connected to my soundcard (for the time being)


The frequency range should go down to 60-70Hz and up to lets say 15khz. (or better)

SPL should be around 90db/W/m. (or higher)

4-6 liters should be sufficiant.

Does anybody have an idea, how a potential solution could look like ?

Hi Klaus,

The Fostex FE87E migth be a nice one (with soft EQ to lower the midrange and thus creating more bandwidth if you like...)

A bit lower tuning for the port (more shallow roll-off) and placed on a shelf or table will boost the deeper bass a bit.

Ciao,

Bert

Thanx. It looks promising. I just looked up a proposal in a DIY magazine.
They put the reflex port down to the surface to extent the low-end. They
just lifted the speaker a bit up to get some air underneath. They were using
an Aurasound NS3-193 8R. The Fostex looks more promising to me, though.
Much better upper range. Higher sensivity.

I'll dig a bit more into it.

Klaus,

In other words (practical) this means that the port is tuned lower (longer path...). Even if you put the port on top (same real total length) then it does not make any difference except for boosting less the lower midrange...

Ciao,

Bert
