Review: Excelente
Review: This is a replacement subwoofer for my Klipsch Promedia 2.1 speaker system that is connected to my desktop computer. I find that this replacement model is superior to the original Klipsch subwoofer that came with the 3-way system. It is very resonant, and handles all the sub-bass notes with ease. This subwoofer adds a whole new dimension to all of my online music. I'm glad to have it.

## Questions & Answers

**Q: what is the outer diameter of the outer most edge of this woofer? please be exact. I'm designing a box.**
A: I know some 6.5" speakers are not 6.5", but these are. Replaced the woofers in my Dayton B652's (which are  6.5" outside diameter) and they went right in.

**Q: Could I use this as a car subwoofer if I put it in a box?**
A: This will give you better bass than most car 6.5's, but it's a replacement woofer for bpokshelf speakers mainly, but home stereo component 6.5's definitely perform better than car ones, some are even 4ohm.

**Q: For those who purchased the speaker as a replacement sub for the Klipsch Promedia, how is the fit and does the amp power the sub as well as the OEM?**
A: They fit perfect except the grill covers do not "push" back into place. Also you have to change the leads on the wiring because the connectors on these speakers are smaller. Really easy to do and they sound great. And yes the amp powers the sub and the OEM.. Super cheap fix, highly recommend.

**Q: What is the frequency of the speaker?**
A: 60-8000Hz

A pesar de ser de fabricación china, cosa que no hay que tener mucho en cuenta, pues muchas marcas de prestigio ya se fabrican en China, con la diferencia de que son mucho más caras y además no hay practicamente diferencia en la calidad de sonido y son mucho más baratas, estos altavoces GRS tienen un sonido bastante aceptable por el precio que tienen, yo los he comprado para sustituir unos Beyma y a mi me gusta mas el sonido que dan estos GRS, que los que tenia de Beyma que se me estropearon, yo llevo mucho tiempo en esto del mundo de la Hi fi, y he aprendido que no siempre hay que fiarse de las marcas sino de tus oidos.
