Overview

Enclosure limits have been made much more generous so sub-liter enclosures, small ports, and very large systems (e.g. multi-driver arrays) are supported. Graph Y-axis controls have been added for manual or auto-scaling of each graph.

Changes

• Box volume: Minimum reduced from 1 L to 0.01 L (10 mL); maximum increased from 1,000 L to 100,000 L.
• Port diameter/width and height: Minimum reduced from 25 mm to 1 mm; maximum increased from 500 mm to 10,000 mm.
• Driver displacement and bracing: Maximum increased from 50 L to 1,000 L.
• Effective volume floor: Lowered so sub-liter effective volumes are allowed while still avoiding zero/negative values.
• Sealed box Qtc: Now displays system Q factor (Qtc) for sealed enclosures, helping users understand damping characteristics (overdamped, critically damped, underdamped).
• Graph Y-axis settings: Each graph now has a settings cog that allows switching between Auto (lenient bounds-checking that adjusts to data) and Manual mode (user-defined min/max range). Settings are persisted per graph in local storage.
• Improved auto-scaling: Auto mode uses lenient thresholds to avoid jarring visual changes while still adapting when data approaches limits. SPL graphs have a 70dB lower limit in auto mode to avoid showing deep bass roll-off.
• Dynamic axis labels: Y-axis labels now always cover the full range, including when custom manual bounds are set.
• Checkbox visibility: Improved contrast of unchecked checkboxes in light mode.
• EQ panel redesign: Unified filter list with single "Add Filter" dropdown. High-pass, low-pass, and parametric EQ filters now share one compact list instead of separate category cards.
• Advanced power options: New "Advanced" panel in the bottom bar exposes series resistance (cable/amp output resistance, default 0.1Ω) and displays calculated driver voltage based on power and DC resistance (Re).
• Results moved to sidebar: Simulation results (F3, F10, Max SPL, sensitivity, excursion, etc.) are now in a collapsible "Results" accordion in the right panel instead of the bottom bar.
• Driver count limit increased: Maximum drivers per enclosure raised from 10 to 50 to support large multi-driver arrays.
