25 Ohm Speaker Loading Resistors

25 Ohm Speaker Loading Resistors


NOTE: We had a massive number of these sell over the weekend and are sold out. Ohmite is making another run for us and we’ll have them ready to ship the first week in February. Orders coming in between now and then will still receive free shipping.

2x matched 25 ohm loudspeaker loading resistors.

Take your 16 ohm Zu loudspeakers to 8 ohms with this simple and effective plug and play solution. Druid, Soul Superfly and Soul Supreme (all versions).

Some amplifiers prefer seeing a heavier load, and one that is more linear. First Watt SIT amps are top of mind, but there are plenty of others. So, here’s an easy plug and play solution for such matchups.

  • Reduce the nominal Z-weighted impedance from 16 ohms to 8 ohms.

  • Reduces the z-weighted dynamic impedance ratio from 5:1 to 3:1.

  • Matched tolerance is equal to or better than 0.5%.

To install simply unscrew the 5-way binding post, slide over the posts, screw the nuts back on. No tools, takes about a minute.

Price is for a matched pair.
