Comparable 5.25" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Peerless HDS-P835024 does not fit your target box volume or tuning. Each entry links to its full enclosure design and Thiele/Small parameters.
⚠️ Engineering Notice for Builders
- Limited linear excursion (Xmax: 3.5 mm); set a high-pass subsonic filter at 25–30 Hz when driven with high power.

Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for Peerless HDS-P835024?
Load Forge's calculated alignment puts Peerless HDS-P835024 in a 4.3 liter vented enclosure tuned to 61.2 Hz, reaching an F3 cutoff of approximately 86.6 Hz.
Can Peerless HDS-P835024 be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 5.4 liters with a Qtc of 0.919 (above Butterworth), the system exhibits an F3 of 87.6 Hz.
What port dimensions should be used for Peerless HDS-P835024 to avoid port chuffing?
Sized from cone displacement (Sd × Xmax), a minimum port diameter of 5.0 cm with a length of 33.0 cm is suggested; check the port air velocity at your drive level in the Load Forge Studio.
