Dynaudio Esotan MKII MF 171 Midrange Speakers | Previous Display
Professionally Maintained Demo Units
Every demo unit has been carefully maintained by our certified technicians. These aren't customer returns or damaged goods - they're the same high-quality equipment we've used to demonstrate premium sound to our customers for years.
Pre-Tested & Verified
Unlike typical clearance sales, every item has been tested and verified by our technical team. We stand behind the quality of our relocation inventory.
Everything Must Go Pricing
These aren't regular sale prices - this is genuine "moving warehouse" pricing. Discounts you simply won't find under normal retail circumstances.
Trade Show Display Models
Many items are pristine display models from major audio trade shows - equipment that's been seen but never installed. These pieces often include special editions or limited releases not available through regular retail channels.
Dynaudio Esotan MKII
MF 171 Midrange Speakers
Hand-Crafted Danish Precision for Uncompromising In-Car Audio Truth
Danish Sound Engineering Excellence Since 1977
Designed in Denmark
Every Dynaudio driver embodies nearly five decades of uncompromising Danish engineering. Founded by Wilfried Ehrenholz in 1977, Dynaudio was born from a simple truth: off-the-shelf speakers weren't telling the whole story.
The Musical Truth
From world-class recording studios to premium home audio, Dynaudio's obsession with accuracy has made them the reference choice for professionals who demand nothing less than sonic perfection.
Vertical Integration
Unlike brands that source components externally, Dynaudio designs and manufactures every driver in-house at their Skanderborg headquarters, ensuring absolute quality control and acoustic coherence.
Why Serious Audiophiles Choose Dynaudio Midrange Drivers
The midrange is where music lives—vocals, guitars, pianos, brass, and the emotional core of every recording. Dynaudio's MF 171 MKII delivers this critical frequency band with studio-grade transparency.
MSP Cone Technology
Magnesium Silicate Polymer delivers the ideal balance of rigidity, damping, and low mass. This proprietary material eliminates cone breakup and resonance, ensuring midrange clarity without coloration—the same technology used in Dynaudio's $50,000+ studio monitors.
19.38mm Aluminum Voice Coil
Precision-wound on a lightweight aluminum former, the voice coil delivers exceptional power handling (120W RMS) with lightning-fast transient response. Aluminum's superior thermal conductivity prevents power compression during extended listening.
Optimized Frequency Range
Engineered for 120Hz–10kHz reproduction (recommended 160Hz–14kHz crossover points), the MF 171 handles the entire vocal spectrum with studio-reference accuracy. Perfectly complements tweeters and woofers in 3-way active systems.
SBR Rubber Surround
Styrene-Butadiene Rubber provides consistent performance across temperature extremes and decades of use. Unlike foam surrounds that deteriorate, SBR maintains its compliance and linearity for the life of your system.
High-Power Magnet System
60x24x10mm neodymium magnet assembly generates powerful magnetic flux (2.973 Tm) for precise cone control and exceptional dynamics. Compact footprint allows shallow 57mm mounting depth for versatile installation.
Precision Tuning Parameters
Carefully engineered Thiele-Small parameters (Qts: 1.012, Fs: 150Hz) ensure predictable acoustic behavior in sealed or vented enclosures. Design your system with confidence using real measured data, not estimates.
Technical Specifications
💡 Installation Note: These midrange drivers are designed for use with Rennspec 76mm mounting adapters (sold separately) for precise fitment in OEM locations. Optimized for active 3-way systems with dedicated amplification and DSP time alignment.
Professional Installation Considerations
Optimal System Integration
🎛️ Active 3-Way Configuration
The MF 171 excels in active 3-way systems (like the Esotan 372 MKII) where dedicated amplifier channels and DSP crossovers provide precise frequency division and time alignment.
- Tweeter: Frequencies above 3.6kHz
- Midrange (MF 171): 160Hz – 3.6kHz
- Woofer: Frequencies below 500Hz
⚡ Amplification Requirements
Minimum: 40W RMS @ 4Ω per channel
Recommended: 60-120W RMS @ 4Ω per channel
Amplifier Quality: Clean, low-distortion amplification is critical—these drivers reveal amplifier deficiencies instantly.
📍 Mounting Adapter Required
These drivers require Rennspec 76mm mounting adapters (sold separately) for secure installation in OEM door panel or dashboard locations. The shallow 57mm mounting depth allows installation in space-constrained applications.
Crossover Recommendations
For optimal performance in active 3-way systems using DSP processors:
High-Pass Filter
160Hz @ 24dB/octave (Linkwitz-Riley)
Protects driver from excessive low-frequency excursion
Low-Pass Filter
3.6kHz @ 24dB/octave (Linkwitz-Riley)
Seamless transition to tweeter
Time Alignment
Essential for phase coherence
Compensate for different acoustic arrival times
Perfect Applications for MF 171 Midrange Drivers
High-End 3-Way Active Systems
The ultimate configuration for audiophile car audio. Pair with dedicated tweeters and woofers, powered by multi-channel amplification with active DSP crossovers and time alignment. Perfect for enthusiasts building no-compromise systems.
Vocal-Centric Listening
If you listen to jazz vocals, acoustic music, classical chamber works, or singer-songwriter material, the MF 171's midrange transparency reveals every nuance—breathiness, vibrato, emotional inflection—with studio-monitor accuracy.
European Luxury Vehicle Upgrades
Originally developed for premium automotive OEM applications, these drivers are ideal for upgrading factory systems in Porsche, BMW, Mercedes-Benz, and Audi vehicles where space is limited but sound quality cannot be compromised.

What types of items are included in the relocation sale?
Our relocation sale includes demo units we've used for customer demonstrations, new old stock from discontinued product lines, and display models from trade shows.

Items range from amplifiers and speakers to processors and accessories accumulated over nearly 10 years at this location.
Do sale items come with manufacturer warranties?
Warranty coverage varies by item and condition. New old stock items typically include full manufacturer warranty if still valid. Demo and display items may have limited or no manufacturer warranty remaining. We clearly state warranty status in each product description. All sales are final on relocation sale items.
How does shipping work for relocation sale items?
We ship relocation sale items using the same careful packaging methods as our regular inventory. Shipping costs are calculated at checkout based on size and weight. For multiple item purchases, we'll combine shipping where possible to save you money. Large items like subwoofer boxes may require freight shipping with additional costs.
Can I return or exchange relocation sale items?
All relocation sale items are sold as-is with no returns or exchanges. We encourage local pickup customers to inspect items before purchasing. For shipped items, we provide detailed descriptions and photos. Since we're relocating, we cannot accommodate returns or warranty service after the sale period ends.
