Make the Dayton Audio line of metallized polypropylene capacitors your standard choice for all of your loudspeaker projects! The same high quality as the competing brands ... but at a much lower price. They are suitable for a wide range of applications. They are ideal for use in loudspeaker crossover networks, or for by-passing large value non-polarized electrolytics. Also a good choice as coupling capacitors in the signal path of audio power amplifiers and preamplifiers. Large values are great for 3-way speaker designs.
