Details Review

Design:

Polk Audio Signature Elite ES15 is available in three different color options. The cabinet is made of Medite MDF and is acoustically inert resulting in reduced standing waves. It is designed to minimize any resonance that might color the sound. It comes with anti-diffraction removable magnetic grille. So, you can either show off the driver design or protect them if you have pets or kids. It has self-adhesive rubber feet to put the speaker firmly in one place.

Performance:

Polk Audio Signature Elite ES15 has 1” tweeter and 5.25” woofer. The drivers use Dynamic Balance technology resulting in minimized resonance, lower distortion and improved efficiency. It has phase-optimized two-way crossover array so that the transition is accurate and smooth. Vocals and instruments sound loud, clean and clear. The higher frequency goes as high as 40kHz and the speaker is known to support Hi-Res Audio Certification.

Mids are precise and detailed which we believe is a result of well-designed drivers. It has Polk’s patented Power Port design for smoother airflow throughout a bigger surface area. Low ends from a 5.25” driver is deep and tight. However, adding a subwoofer enhances the sound even more. It has wide sweet spot that engages the user in the sound.

The speakers are compatible with Dolby Atmos or DTS:X surround sound AVRs. If the receiver has bass management feature, set the speaker to small. Polk ensured you receive audiophile grade sound. While placing the speakers keep an equal distance between the speakers and between speaker and user. Toe-in and adjust them in order to find the suitable spot. They can also be used as rear or surround speakers. Allow the speakers to go through burn-in period to get optimum performance.

Connect a matching amplifier with Polk Audio Signature Elite ES15. Use the available ports on the amplifier to connect audio sources (TV, turntable, PC, laptop) to the speaker. Use control options like remote, voice control available on the amp to control the speaker.

Use case:

The Polk ES15 is great for music and movies. That said, we suggest a sub for music lovers and a 3.1 system for movie freaks. If you want a bigger model, check the Polk ES20.

Compatible Device:

Connect the ES15 to Yamaha A-S501, Aiyma A07 Pro or choose one as per your own preference. The Polk ES15 is easy to drive so finding a compatible amplifier is easy.

FAQ: 

 

Is room acoustics important in Polk Audio Signature Elite ES15’s performance?

Room acoustics or layout plays vital role in a speaker’s performance. While we can’t create a perfect room, we can definitely improve the acoustics with different materials. Some amplifiers also come with room calibration software that optimizes the sound as per the layout.

How many subwoofers should I add with Polk Audio Signature Elite ES15?

A single subwoofer is enough for general users and will boost the overall performance. However, if you want accuracy and consider yourself an audio enthusiast, then you can also pair two of them. Make sure the amplifier has dual sub out port.

Debut 2.0 B6.2

Design: Elac Debut 2.0 B6.2 is a modern looking bookshelf speaker that has black ash vinyl finish. The enclosure is made of MDF and the speaker has internal bracing to minimize vibration while improving stiffness. Since it has a port on the front side, placement near walls is flexible. It has a removable cloth grille. Build quality is good and feels durable. Performance: The soft dome tweeter ensures the highs are realistic and lively. It minimizes any diffraction and enhances directivity. It has dual flared port and the 6.5” aramid woofer is much better than polypropylene used in other speakers. With higher stiffness and damping, it can deliver smoother low ends. Since the speakers can get as low as 44Hz, low ends are cleaner and deeper to suit most users. Music, movies, shows or games, you name it. The speaker can be used for any type of content with ease. That said it is better to add additional equipment for specific purpose. Like, create a 5.1 system for movie theater, add a center channel with TV or sub for music listening purpose. Sensitivity and impedance of the speaker is chosen such that it is easy to drive even with a center channel. Allow the speakers to go through long hours of break-in and make sure you give attention to room acoustics. These additional features affect the performance more than we think. For placing the speakers on the front side, create an equilateral triangle between speakers and speaker to user. Alter the position by ‘toe-in’ and like other speakers, it should be at the ear level. If you use them as rear speakers, place them far away compared to front side placement. Keep the speakers at a height that is a bit higher than ear level. Connectivity: Connectivity will depend on the amplifier you choose. Make sure it has your preferred ports like HDMI for TV or built-in preamp for turntable. Use case: Use the Elac Debut B6.2 speaker as a stereo speaker, as front or rear speakers. Or, include them in a home theater. The Debut B6.2 is great for playing music and movies. For audiophiles, we suggest a powered subwoofer. It is best for medium sizes rooms but you can also use it in large spaces. However we suggest to expand it to 3.1 or 5.1 in large spaces. Compatible device: Connect the speaker with a matching amplifier by using high quality speaker wires. You can use Amazon Basics speaker wire. You can use Marantz PM 8006, Peachtree Nova 300, Yamaha r-n303, Onkyo tx-8140, Marantz PM-6007, Yamaha A-S501, Yamaha R-S202, Denon PMA-600NE. Simply choose one that matches your budget and have your desired features. Pair the Debut B6.2 with floorstanding loudspeakers (DF52/DF62), bookshelf loudspeakers (DB52/DB62), center-channel loudspeakers (DC52/DC62), a Dolby Atmos enabled loudspeaker (DA42), and powered subs (S10EQ/S12EQ). Ease of use: This will depend on the amplifier. Most of them are easy to use with good controls. Cost: Elac Debut 2.0 B6.2 sounds bigger than its cost. The price is reasonable and budget-friendly. However, if you add an amp and sub, the total price will increase. FAQ: How to connect a center channel with Elac Debut 2.0 B6.2? In order to pair a center channel with Elac Debut 2.0 B6.2, you need to look for ports on the rear side of your amplifier. You can’t connect them directly as they are passive speakers.

ELAC Debut Reference DBR62 Bookshelf Speakers

Instead of usual black, we love the white color and blends with our décor easily. It has ‘full perimeter brace’ for top and side panels. This is done to minimize any cabinet vibration. Build quality is good and it comes with a removable acoustically transparent cloth grille. Performance: ELAC Debut Reference DBR62 has one tweeter and one woofer in each cabinet.

Trebles and mids are good, low ends pack a punch. Mids are clean, clear and gives you a sweet listening experience. Compared to its compact size, bass is full and impressive. If you want to go lower than 44Hz, easily pair an 8” subwoofer via the amp. Allow the bass to open up by connecting an Elac Sub 1010. While 2200Hz crossover is listed for the speaker, keep it to 70 to 80 Hz for the subwoofer given that you are creating a 2.1 system. Allow the speakers to go through break-in period so that you can listen to rich and warm sound. For placement, Elac wants users to follow basic rule where you need to place the speaker 1 to 2 feet away from walls and corners. Place them, then toe-in to get the best position for optimum performance. Instrumental sounds are clear and accurate. Use it for music and movies or connect it to your PC via an amp to play games.

If you can compromise the sound, you can also place it in large spaces, then expand when you have the budget. It can handle music very well; we suggest pairing a sub for audiophiles.

Some compatible subs are Elac powered subwoofer (SUB310 or SUB312). Cost: Going above $500, Elac Debut Reference DBR62 isn’t the cheapest speaker in the market. Consider this a mid-priced model. We suggest going for it if you already have a sub, otherwise the total cost will increase further. FAQ: How to improve Elac Debut Refernce DBR62 performance? In order to improve Elac Debut Refernce DBR62 sound quality, you can use damping pads under the speaker. Allow the speakers to go through long hours of break-in. Lastly be aware of the fact that room acoustics play important role in audio performance. Use EQ options or room calibration in the amp. For home theaters, make sure to use materials to improve room acoustics. Is it mandatory to use a speaker stand with Elac Debut Reference DBR62? Speaker stands are not mandatory at all.
