My Buying Guides on Definitive Technology Demand D17
When I decided to upgrade my home audio setup, the Definitive Technology Demand D17 caught my eye. After spending some time researching and testing, I wanted to share my insights to help you decide if these speakers are the right fit for you. Here’s my comprehensive buying guide based on my experience with the Demand D17.
Design and Build Quality
One of the first things that impressed me about the Demand D17 was its sleek, modern design. The compact, bookshelf size made it easy to fit into my living room without dominating the space. The black ash wood veneer finish gave it a premium look that matched well with my other audio gear. The build quality felt solid and durable — definitely made to last.
Sound Performance
For me, sound quality is the most crucial factor, and the Demand D17 didn’t disappoint. The speakers deliver clear, detailed highs and a surprisingly rich bass for their size. The 1-inch aluminum dome tweeter and dual 5.25-inch mid/bass drivers work together to provide a full range of sound. I found the soundstage wide and immersive, making music, movies, and even gaming more enjoyable.
Power Handling and Compatibility
The Demand D17 is rated for 20-150 watts RMS, which worked perfectly with my mid-range AV receiver. If you have a powerful amplifier, these speakers can handle it well without distortion. I also appreciated their 4-ohm impedance, which meant I needed to ensure my receiver could handle that load — something to keep in mind when pairing.
Placement and Room Considerations
Because these are bookshelf speakers, placement is key. I placed mine on sturdy stands about ear level when seated, which significantly improved the sound clarity and bass response. They also work well on shelves or furniture but avoid placing them too close to walls to prevent sound reflections that muddle the audio.
Connectivity and Setup
The Demand D17 uses traditional speaker wire connections, which is standard but worth noting if you’re used to wireless or powered speakers. Setup was straightforward — just connect to your receiver, position them properly, and start enjoying. I also recommend experimenting with toe-in angles to find the best sound for your listening position.
Value for Money
In my opinion, the Definitive Technology Demand D17 offers excellent value. You get high-end sound performance and quality materials at a price point that is reasonable compared to other speakers in this class. Whether you’re upgrading from basic bookshelf speakers or building a home theater system, these are worth considering.
Final Thoughts
After using the Definitive Technology Demand D17 for several weeks, I can confidently say they are a fantastic choice for anyone looking for compact, high-performance bookshelf speakers. Just make sure your amplifier or receiver matches their specs, and take some time to place them thoughtfully. If you want detailed, dynamic sound without breaking the bank, these speakers are definitely worth checking out.
