What's unique about the brand

Coastal Source is an American maker of outdoor speakers and lighting, founded by Franco D'Ascanio. It grew out of his family's design-build firm in the Florida Keys, which could not find outdoor products that would last. Every product is built around the patented Coastal Connector, which plugs together and twists shut to make an airtight, watertight joint with no splicing in the field. A speaker system can be installed entirely outside, without drilling through the walls of the house. The lighting fixtures are solid cast brass, and the company sells through trained dealers and contractors.

Products overview

Every Razor model pairs ultra-shallow drivers in a slim enclosure with the Acoustic Fractal Waveguide tweeter bridge, which improves clarity and efficiency outdoors. The RZ110 Satellite is the entry model and keeps the footprint small. The RZ220 3-Way adds a third driver range, so voices and bass get their own drivers in a larger space. The Line Source at the top uses a line array to hold high volume and fidelity over long distances across a big property.

  • Start here. If you are on a tight budget, the RZ110 Satellite is the lowest priced way into the Coastal Source sound, in a slim enclosure.
  • Sweet spot. The RZ220 3-Way gives you a third driver range, so bass and voices come from their own drivers and music stays clean at higher volume than the RZ110 Satellite in a bigger space.
  • All in. The Line Source is a separate, much more expensive design rather than an extension of the Razor line, and its variable waveguide narrows dispersion so listeners far across a large yard still hear clear, loud sound.

About the brand

Aerial Acoustics is an American loudspeaker maker founded in 1991 by Michael Kelly and David Marshall. Its first speaker, the Model 10T, was Stereophile's Speaker of the Year in 1996, and every Aerial product is designed and assembled at its factory in Massachusetts. The cabinets are curved, laminated, thick-walled and heavily braced, and almost all the drivers are custom-made to Aerial's specifications, including modified ScanSpeak ring-dome tweeters. Among the floorstanders, the 5T suits small to moderate rooms, the 6T adds a dedicated midrange driver, and the 7T extends the bass for larger spaces.

About the brand

Zu Audio is an American speaker maker that builds around full-range drivers. A full-range driver covers much of the frequency band without a crossover in its path, and many models add a super-tweeter. The speakers are highly efficient, so they pair well with low-powered tube amplifiers. Some models use ZuGriewe and scatter plate internals to improve bass and midrange. The compact DWX has a front-firing port that suits confined spaces, and it is on our Best Speakers for Tube Amps list. The Definition 6 pairs two full-range drivers with a powered subwoofer section.

About the brand

Perlisten is an American speaker and subwoofer maker, founded in 2016. Its speakers are built around the DPC (Directivity Pattern Control) array, a computer-modeled waveguide and driver arrangement that controls how sound spreads into the room, which reviewers credit for precise imaging. S-Series models pair a beryllium dome tweeter with thin-ply carbon diaphragm drivers. In 2020 Perlisten had the first products certified to THX Dominus, a standard for high output at low distortion in large rooms. The S5t is the tower for slightly smaller rooms, and the S7t is on our Best Floorstanding Speakers list.

Our interview with the brand

What are two key technological innovations or strong opinions that differ you from other brands?

As for as tech breakthroughs, we have our patented DPC array: a tweeter inside two midranges. This improves sensitivity and dynamics through such light drivers (3g or less).

Across our entire line, you’re getting 3D soundstaging, detail, dynamics, and low distortion. Most noticeable to the listener is the way sound propagates throughout the room: we focus on a wide dispersion left and right, and slightly limit it top to bottom to minimize first reflections on the floor and ceiling. This makes the speakers easier to place.

As you move up price in our line, the extent to which we do this passive beamforming on the vertical axis descends into a lower and lower frequency.

What's your approach to customer support?

What are your favorite tracks for showcasing the strength of your products?

What other products pair best with yours?

Perlistens are generally not difficult to run. Take the S7t for example: High 80s, low 90s sensitivity. That can run with anything. But, because Perlistens can play so loud, they do like a lot of power to fully show off.

Two brands we generally pair Perlisten with: On the upper end is Audioflight from Italy. On the budget friendly end, Primare. But they've been paired with so much—we haven't come across a pairing they don't work with unless it's a 3W triode tube amp due to insufficient power.

About the brand

Bowers & Wilkins develops many of its own components in pursuit of a speaker that adds nothing to a recording and takes nothing away. The British company, founded in 1966 by John Bowers, pioneered Kevlar cones and developed the Matrix cabinet to cut resonance. The flagship Nautilus, built for dedicated listening rooms, uses tapered damping tubes to lower distortion. The 606 S3 and 603 S3 open the range with a Titanium Dome tweeter, and the 700 Series adds a Carbon Dome tweeter and Continuum cones. The Zeppelin is on our Best Wireless Speakers list.

About the brand

Dynaudio's idea is to make its own drive units, from diaphragm to magnet, even for its entry-level speakers. The Danish company was founded in 1976 and builds its Heritage Special and Contour Legacy by hand in Skanderborg. The flagship Confidence range uses the Esotar 3 tweeter, whose Hexis inner dome damps resonance. Reviewers hear a smooth sound that suits long listening sessions. The Core and LYD ranges are studio monitors. The Emit range shares MSP cones with Evoke and suits smaller rooms, and the Special Forty is on our Best Bookshelf Speakers list.

About the brand

Larsen HiFi is a Swedish maker of Ortho Acoustic speakers, an approach created by sound engineer Stig Carlsson. John Larsen built Carlsson's speakers in Skillingaryd before launching the Larsen range with partner Anders Eriksson. The speakers are designed to integrate almost completely with the front wall, so they become a discreet part of the room. They use reflections from the room's surfaces as part of the sound, which the company says adds timbre and fullness. The Larsen 6 is the mid-priced model, and the Larsen 9 flagship has two upward-facing ambience tweeters.
