These speakers sound great, i put them into a custom build i did with a portable box. They’re super compact and 30 watts each, which seems like a lot for how small they are. They also came with wires too that came in handy for my custom build. Highly recommend

I put these in my Porsche Boxster to replace door speakers, and they are fantastic! They slotted right into the previous wiring and it was all ready to go! They replaced my previous speakers which were rattling and solved that problem. The sound quality for the size is impressive! Would recommend.

I. Bought these speakers to teplace the midrange speakers in my 1978 Pioneer CS 407 speakers. They are a perfect fit, and my 407s sound great again.
