ResoNix Recommended Tuning & Measurement Kit

This is our go-to measurement bundle at ResoNix, built specifically for accurate DSP tuning, acoustic measurement, and system calibration while following our ResoNix DSP Tuning Tracks & Guide. It includes the two pieces of gear we trust every day: the Earthworks M23 G2 precision measurement mic and the Focusrite Scarlet 2i2 USB measurement interface. You also get a free 6-foot XLR cable to connect them directly—no guesswork or missing links.

You can find the Earthworks M23 G2 90 Degree Calibration file here.

The Earthworks M23 G2 is one of the most trusted reference microphones in the audio world, with flat frequency response from 5 Hz to 23 kHz and max SPL handling of 140 dB at full phantom power. Each one is individually calibrated and built from stainless steel with an IP54 rating.

The Focusrite Scarlett 2i2 is a compact USB audio interface widely used for measurement and general audio tasks, offering two high-quality mic or line inputs with phantom power and low-noise preamps. It connects easily to Windows and macOS systems and provides reliable, predictable performance for signal capture and playback during tuning and measurement work.

This is the exact kit we use for tuning work at ResoNix, and it’s the one we recommend to anyone serious about doing clean, reliable measurement and analysis.

Your questions answered.

Every vehicle and goal set is different. Start with our sound deadening buyer’s guide to understand what each material does and where to use it. If you want a tailored plan, book our sound system design and installation consultation.


To help offset the cost, up to 40% of the consultation fee can be credited toward ResoNix product purchases made within 30 days.

Most people ask this because they are not sure what physically fits. Fitment varies by vehicle, trim, and where you plan to install it. Check available depth carefully and avoid interfering with moving parts, window tracks, airbags, and service access. As a general rule, choose the thickest that comfortably fits the space. See the product page for details.

We are building an ongoing fitment sheet from customer confirmations. If you can share what fit in your vehicle, please let us know to help others.

If an item is on backorder, the estimated restock date appears on its product page and is updated as we get new information.

Domestic orders that include a backordered item will ship in two parts: in‑stock items ship immediately, and the backordered items ship as soon as they arrive. For international orders, we currently ship when all items are in stock.

You will receive an order confirmation by email, then a tracking email once your order ships. If you need an update or anything looks off contact us with your order number.

We recommend high‑quality, proven DSPs matched to your system design and goals. If you want a custom recommendation, book our sound system design and installation consultation.
