D'Appolito with Visaton Drivers. No BASS!!

D_GR8_1 · 10th November 2004, 01:06 AM

Hi,

I made two speakers in a D'appolito config using the Visaton W130S & DW72 drivers.

The Woofers W130S are 4Ohm each & the DW72 is 8 Ohm.

My plan was two 4 Ohm in series to give me 8Ohm which in turn is paralleled with 8Ohm Woofer.

Woofers are bandpassed at 90Hz & 5Khz.

Tweeter is HP at 5Khz.

When I play them, I have Pioneer Amp, tried it with Gainclone, and various other amps, unless I use an equaliser or tone control, the speakers produce very little bass.

Does anyone know what the problem is?

Most of the "bass" I hear in music happens between 40hz and 80hz.

If you roll off your woofers at 90hz you are cutting out all the bass.
