Hello all,

I decided to upgrade my 3 way Yamaha 8 inch bookshelf speakers with better components but am having problems. I lost most of my bass and the original speakers sound much more bassy. How can I get getting the bass like the original speaker. What am I doing wrong.

The Yamaha speaker has the following components:
Tweeter 8 ohms
Mid 3 inch back sealed 7 Ohms
Woofer 8 inch 6.5 ohms
It has a two capacitors going to the mid and tweeter. The woofer had direct connection to plus and minus. The specs say ist s 90dbs speaker. It sound very nice but I wanted to use it in a home theater application with better mids and better clarity.

Here is what I put in it.
Tweeter 8 ohms

Dome Midrange 6 ohms 90 dbs
Dayton Audio DC50F-8 2"

Woofer is 8 inch 8 ohms 85 dbs
GRS 8PR-8 8" Poly Cone Rubber Surround Woofer

3 way crossover
Crossover 3-Way 8 Ohm 800/5,000 Hz 100W

also a Adjustable L-Pad on Midrange to adjust sound level.

Speaker dimensions:
high : 14 inches
Width: 10 inches
Depth : 11 inches
Sealed box
I did a calculator to get the cubic feet it cam out to be 0.98.

Why am I loosing all my bass. Is there something I can do to improve the base. I love the mid and tweeter sounds but dont know why the bass is not there.

Do I need to find a better woofer with higher Dbs value like 90 dbs?
Do I need to get speaker damping material to increase bass output? Will that increase my speaker cabinet volume from 0.60 cubic feet to 0.89 cubic feet?
Should I use LPad's to lower the Dbs values to 85 dbs which is the woofer and see what happens?

Any help would be greatly appreciated.
Many thanks
