Box-fit finder · Beta

Find a driver for the box you already have.

Your box, your amp. Every candidate is simulated under identical conditions — drag the power and watch response, excursion and port limits react.

Your box & amp

Every candidate is simulated in this exact box at the same power.

Port length works out to 288 mm.

See every candidate working in your box.

Describe the enclosure and your amplifier. Bits simulates the live shortlist in that exact box under the same power and assumptions, then charts response and excursion with the limits marked, so you can drag the power and watch what breaks first.

  1. 1Describe the box you own, or the one you plan to build.
  2. 2Set the power you’ll actually run.
  3. 3Compare curves, prices and real power handling.

Simulations are comparative estimates, not guarantees. Check the source data and validate thermal, excursion, port and construction limits before building.
