I love these woofers!Summary:- Used in Pioneer CS-G303 cabinet (replaced original woofer, but still using original midrange and tweeter) - see photo- A Sony STRDH130 2 Channel Stereo Receiver is being used to drive themI bought these woofers to replace my aging and deteriorating Pioneer ones, which were approaching 30 years old. Not a bad run, but they were showing their age. These GRS (Parts Express) woofers didn't exactly fit in the Pioneer cabinets due to the inner bevel - the cut-out needed to be enlarged about 1/16th of an inch. Once that was set, they fit perfectly.These speakers are used in my garage, so they're purely for casual listening. With that said, I was kind of shocked at just how good they sounded. They have a tighter feel along with a slight bump in the low end compared to the old ones. Using a sample tone album I found on Spotify (search for the album Audio Test Tones) I was able to get a great response down to 40Hz, but once I got below that it drops off quickly. 30Hz barely registered. Your mileage may vary depending on the enclosure you install these in and the amp you use. I use these speakers only for music, so this is more than good enough. I've listened to these for about 10 hours and they had no issue playing loud for long periods (3 or 4 straight hours).Spending a little money on these woofers I'm hopeful I've extended the lifespan of these old Pioneer speakers for many more years to come. Highly recommended!
