Sub Car
Can I hook up a Car Sub to my floor standing speakers?
I have a 4 ohm reciever and 4 ohm floor standing speakers. The speakers need replacement woofers. Can I just hook up some 4 Ohm Car subs (with low RMS rating) and be good to go?
Anyone that tells you yes that's all you gotta do doesn't know shit about speakers. Unfortunately it's not that simple. You could do that but it's not gonna sound the way it's suppose to. In other words it's not going to sound identical to the original set up. UNLESS the Thiele/Small parameters of the replacement woofer are identical to the original woofers. Too many variables are involved. Impedance of course must match but the sensitivity rating should also match so that it plays just as loud as before. You don't want the bass overpowering or sounding too thin. The woofer's frequency response must also be the same or at least VERY close to the original. If the cabinets are ported then it's a shot in the dark because the cabinets were designed to a specific internal volume with the port being a specific diameter and length for that particular woofer. Of course the woofer must be one suitable for ported enclosures. The original woofer's Thiele/Small parameters are used to calculate all of that. You don't just build a box and put any port in it and install any woofer. There's a science to it. By the same token, if the cabinets are sealed then the replacement woofer must be designed for a Sealed Enclosure and must be compatible with the cabinet's internal volume. In order to get the same type of bass response the woofer's "Qts" parameter must be the same. To make a long story short, yes you could just replace the woofers and it will work but if you want it to sound good then you need to read this. And this information just scratches the surface about speakers.
