Review: GNS 8” subwoofer - I replaced my outdoor deck system sub with speaker and am very pleased, listening to my jazz on Spotify, I have a hodgepodge system consisting of a Pyle Bluetooth amp some goodwill akai 3ways and an old Optimus r50 home sub amp, this speaker for the money sounds ridiculously good! Nice full punch and very little flab! Great subwoofer for an affordable price

## Questions & Answers

**Q: Wattage? Kind of important info to leave out....**
A: I push 125w PC through crossover in speakers I built with no trouble or distortion. The magnet is heavy enough to make it a strong driver. GRS does not list any kind of wattage ability or limits in the box they came in.

**Q: Hi guys. i have a energy e:xl-s8 8" 100 watts sub woofer and i need to replace the cone,but not sure winch one to use. any recommendation. thanks**
A: You need dual voice coil 4 or 8 ohm 8 inch driver. A "sub woofer" driver. They have longer cone excursion abilities than regular woofer drivers.

**Q: I need to replace a Bose 601 8" 4 ohm speaker, I don't know the specs of it but will this "subwoofer" substitute for it if it is a regular woofer?**
A: The 4-ohm version should work.  I replaced an 8" driver in an Infinity speaker, and it compares well (subtle differences) side-by-side with the other speaker.   May work but cannot assure the quality will match the existing speaker.

**Q: what is the measurement across the front of speaker or top of speaker.**
A: Diameter is 8 1/4th inches from top of basket top edge to edge.
