DINAS Passive – Do I Need a Subwoofer
This is the build plans for the newest version of the famous DINAS speakers. These utilize a side firing passive radiator to increase sound quality. In addition, I listened to you guys wanting the ability to use your favorite amplifier. With this is mind, these use passive crossovers, so that you can now use whatever amplifier you want, allowing these to become more versatile for you. For those who aren’t familiar with the original Dinas. Dinas is short for Do I Need a Subwoofer. This is due to each speaker having it’s own subwoofer that goes down to an impressive 32hz. These are the new and improved version of the originals that you saw on Toids DIY Audio from YouTube build and JoeNTell Review. This updated version uses a side firing passive radiator instead of ports, making it even easier to build the cabinet. They also use a custom passive crossover, which allows you to use your favorite amplifier that can handle 4ohm speakers. These are very powerful set of speakers that uses these components:

For a pair of speakers the component cost is around $250-$300.

About The DINAS
Each speaker has it’s own redesigned voxel subwoofer. It is redesigned with a Passive Radiator that removes port noise and increases sound quality. They feature a full range driver in it’s own sealed enclosure and a tweeter to help give the speaker a full frequency range to 20khz.
The projected Frequency response is around 32hz-20khz, making these a true full range speaker.
The final speakers are a nominal 4 ohm speaker and will run off any of your favorite amplifiers that are rated for 4 ohm speakers.
