Setting Up Your BP20s

Alright, you've got your hands on a pair of Definitive Technology BP20s. Awesome! But now comes the crucial part: setting them up correctly. Don't worry, it's not rocket science, but a few key considerations can make a huge difference in how they sound. Let's walk through the essential steps to get your BP20s singing their best.

First and foremost, placement is king. Because the BP20s are bipolar speakers, meaning they radiate sound from both the front and the back, their placement is more critical than with traditional front-firing speakers. The goal is to create a balanced and immersive soundstage, and that starts with finding the right spot for each speaker. Generally, you'll want to position them a few feet away from the rear wall to allow the sound from the rear drivers to reflect and create that spacious soundstage. Experiment with different distances to find what sounds best in your room. Also, ensure they are equidistant from your primary listening position to maintain proper stereo imaging.

Toe-in is another important factor. Toe-in refers to the angle at which the speakers are pointed towards your listening position. Some people prefer to have the speakers pointed directly at them (full toe-in), while others prefer to have them angled slightly outwards (no toe-in). The best approach is to experiment and see what sounds best to your ears. A good starting point is to angle the speakers so that they intersect a point just behind your head. This can help to create a wider soundstage without sacrificing focus.

Speaker height is also something to consider. Ideally, you want the tweeters to be at ear level when you're seated in your listening position. If your BP20s are sitting on the floor, you might want to consider using speaker stands to raise them to the proper height. This will ensure that you're getting the best possible high-frequency response and clarity.

Next, let's talk about connections. Make sure you're using high-quality speaker cables to connect your BP20s to your amplifier. While expensive cables aren't always necessary, it's worth investing in cables that are properly shielded and have good quality connectors. Also, double-check that you've connected the positive and negative terminals correctly on both the speakers and the amplifier. Getting this wrong can result in phase cancellation and a significant degradation in sound quality.

Room acoustics play a significant role in how your BP20s will sound. Hard surfaces like walls and floors can reflect sound waves, creating echoes and resonances that can muddy the sound. Soft surfaces like carpets, curtains, and upholstered furniture can absorb sound waves, helping to reduce these unwanted reflections. Consider adding some acoustic treatments to your room to improve the overall sound quality. This could include things like bass traps, acoustic panels, or diffusers.

Finally, take your time and experiment. Don't be afraid to move the speakers around, adjust the toe-in, and try different settings on your amplifier. The goal is to find the setup that sounds best to your ears in your room. It might take some time and effort, but the end result will be well worth it. Once you've got your BP20s dialed in, you'll be able to sit back, relax, and enjoy your favorite music and movies like never before.
