Let us help you find the RIGHT replacement speaker for your cabinet.
You can't just put any replacement speaker in your cabinet and expect it to sound good.
Every speaker system (worth it's weight) was engineered with a specific woofer in mind.
So, it is usually best to try and replace your woofer with an original when possible.
But many times finding the original woofer is impossible (or very expensive).
This is where the Parts Express Speaker Wizard comes to the rescue.
By using Thiel/Small parameters and reverse engineering, the Wizard will find a woofer
that will sound as close to the original as possible. All you have to do is answer a few
questions about your speaker cabinet (internal volume, ported or sealed, impedance, etc)
and the Wizard will do the math. It's that easy. (more info)
