Klipsch RSM-400 Indoor/Outdoor Residential Surface Mount Loudspeaker at Vinyl Sound Toronto Canada

The RSM-400 is a two-way, full-range residential surface mount loudspeaker from Klipsch (Indianapolis, USA), available at Vinyl Sound in Toronto, Canada. Designed for homeowners who want authentic Klipsch sound quality in outdoor and indoor settings, the RSM-400 pairs a 4" injection-molded polypropylene woofer with a 3/4" titanium compression driver mounted on a 90x90 degree Modified Tractrix Horn for effortless, wide-dispersion audio. The sealed ABS enclosure carries an IPX5 weather resistance rating, making it suitable for patios, decks, porches, pool areas, sunrooms, and covered outdoor spaces. Dual 5-way binding posts support flexible wiring configurations, and the included adjustable C-style bracket allows mounting in both horizontal and vertical orientations. Available in black or white, the RSM-400 is sold as a pair for complete residential installations.

Tractrix Horn Technology: Wide, Even Coverage Across Your Outdoor Space

Klipsch has built its reputation on horn-loaded speaker technology, and the RSM-400 brings that legacy to residential outdoor audio. The 3/4" titanium dome tweeter is mounted on a 90x90 degree Modified Tractrix Horn, a geometry engineered to distribute high-frequency energy evenly across a wide listening area without the harshness or beaming typical of conventional dome tweeters. The 90-degree horizontal and vertical dispersion pattern means listeners positioned off-axis still hear clear, detailed sound rather than a narrow, directional beam. This makes the RSM-400 particularly effective for open decks, poolside areas, and gardens where listeners move freely rather than sitting in a fixed sweet spot.

Sealed Enclosure Design for Outdoor Durability and Clean Bass

Unlike many outdoor speakers that use ported enclosures prone to moisture ingress and port noise in extreme conditions, the RSM-400 uses a fully sealed ABS cabinet tuned for clean, accurate bass reproduction down to 79Hz. The sealed design minimizes harmonic distortion at higher playback levels and eliminates the chuffing and coloration associated with exposed ports in outdoor environments. The all-weather ABS plastic cabinet is paintable to match any exterior color scheme, and the rust-proof aluminum grille is secured with set screws on each side to stay firmly in place regardless of wind, vibration, or handling. The IPX5 rating confirms protection against water jets from any direction, covering everything from rain and sprinkler overspray to poolside splash.

Key Features

  • 4" Polypropylene Cone Woofer: Injection-molded polypropylene cone resists moisture absorption and maintains consistent performance in humid outdoor environments, delivering balanced mid-bass reproduction.
  • 3/4" Titanium Compression Driver on Modified Tractrix Horn: Titanium dome tweeter mounted on a 90x90 degree Tractrix Horn provides wide, even high-frequency dispersion across the listening area with minimal distortion.
  • IPX5 Weather Rating: Certified resistant to water jets from any direction, making the RSM-400 suitable for outdoor residential installations including patios, decks, pool surrounds, and covered porches.
  • Sealed Cabinet Tuning: Fully sealed ABS enclosure minimizes distortion at higher output levels and resists moisture infiltration better than ported designs in outdoor environments.
  • Dual 5-Way Binding Posts: Accepts banana plugs, spade lugs, bare wire, and pin connectors, supporting flexible speaker wire routing and simplified connection for residential installations.
  • Set Screws on Grille: Rust-proof aluminum grille is secured with set screws to prevent accidental removal in windy or high-traffic outdoor environments.
  • Adjustable C-Style Mounting Bracket: Corrosion-resistant aluminum bracket supports wall and ceiling mounting in both horizontal and vertical orientations, with angle adjustment for precise sound direction.
  • Rotating Logo: The Klipsch logo badge rotates to remain correctly oriented whether the speaker is installed horizontally or vertically.
  • Paintable ABS Enclosure: All-weather UV-resistant ABS plastic cabinet can be painted to blend with any exterior wall color or architectural finish without affecting acoustic performance.
  • Sold as a Pair: Each package includes two RSM-400 loudspeakers with pre-installed grilles, mounting brackets, bracket knobs, and hardware.

Frequently Asked Questions

What is the Klipsch RSM-400?

The Klipsch RSM-400 is a two-way, sealed residential surface mount loudspeaker featuring a 4" polypropylene woofer, a 3/4" titanium compression driver on a 90x90 Modified Tractrix Horn, and an IPX5 weather rating. It is sold as a stereo pair and designed for residential indoor and outdoor installations including patios, decks, pool areas, and porches. The RSM-400 handles up to 40W RMS per speaker and delivers a maximum continuous output of 98 dB.

How does the Klipsch RSM-400 compare to the Polk Audio Atrium 4 or Bose 151 SE?

The Klipsch RSM-400 delivers a measurably wider and more consistent dispersion pattern than the Polk Audio Atrium 4 and Bose 151 SE, thanks to its Tractrix Horn-loaded titanium tweeter with a 90x90 degree coverage angle. The Atrium 4 uses a conventional dome tweeter with narrower off-axis response, while the Bose 151 SE relies on a full-range driver configuration that can compress at higher output levels. The RSM-400's sealed enclosure also produces cleaner, lower-distortion bass compared to the ported designs of many competing outdoor speakers, though its bass extension (79Hz) is comparable to similarly sized alternatives in its class.

Can the Klipsch RSM-400 be mounted horizontally and vertically?

Yes, the RSM-400 supports both horizontal and vertical mounting orientations. The included C-style aluminum bracket accommodates both positions, and the Klipsch logo badge rotates so it remains correctly oriented in either configuration. The bracket also provides angular adjustment after mounting so the speaker can be precisely aimed toward the listening area.

What is the Tractrix Horn on the RSM-400 and why does it matter?

The Modified Tractrix Horn on the RSM-400 is a mathematically derived horn geometry that controls how high-frequency sound expands as it leaves the tweeter. Klipsch's 90x90 degree configuration means the horn distributes energy equally across a 90-degree horizontal and 90-degree vertical field, rather than concentrating it in a narrow beam. This produces a larger, more even listening area compared to conventional dome tweeters, and the horn loading improves tweeter efficiency so the driver requires less power to achieve the same output level, reducing distortion at typical listening volumes.

Where can I buy the Klipsch RSM-400 in Toronto or Canada?

The Klipsch RSM-400 is available at Vinyl Sound, an authorised Klipsch dealer in Toronto, Canada. Vinyl Sound carries the full Klipsch residential speaker lineup and ships across Canada. Buying from an authorised Canadian dealer ensures manufacturer warranty coverage and access to knowledgeable installation support for your home audio project.

Is the Klipsch RSM-400 suitable for year-round outdoor use in Canada?

The RSM-400 carries an IPX5 rating, meaning it is certified to withstand sustained water jets from any direction, covering rain, sprinkler exposure, and poolside splashing. The UV-resistant ABS enclosure and rust-proof aluminum grille are engineered for prolonged outdoor exposure. For Canadian winters with sub-zero temperatures, it is advisable to mount the speakers in a sheltered or covered location and to use outdoor-rated speaker wire rated for direct burial or low-temperature flexibility to ensure long-term reliability.

What amplifier or receiver do I need to drive the Klipsch RSM-400?

The RSM-400 operates at a nominal impedance of 8 ohms and handles up to 40W RMS per speaker, making it compatible with a wide range of standard stereo receivers, AV receivers, and outdoor amplifiers. Its sensitivity of 85 dB means a modest 10 to 40 watt per channel amplifier delivers ample volume for typical residential outdoor settings. The dual 5-way binding posts accept banana plugs, spade lugs, or bare wire, so connection to virtually any amplifier output is straightforward without adapters.

Can the RSM-400 be painted to match my home exterior?

Yes, both the ABS plastic enclosure and the aluminum grille of the RSM-400 are fully paintable. Klipsch designed the cabinet and grille to accept standard spray paint without requiring a special primer in most cases, allowing the speakers to be color-matched to any exterior wall, trim, or architectural finish. Available in black or white from the factory, most homeowners find that one of the standard finishes or a custom paint application blends the speakers seamlessly into the surrounding environment.

Great product if you know what you’re getting.
Size: 4-tier, Style: wall mount&floor mount, Size: 4-tier, Style: wall mount&floor mount
It’s a great product if you know some details before you purchase. Specifically, for how much it cost it’s a great product. After assembly it is sturdy and will hold anything you’ll be displaying on it within reason. Speaking of assembly, it’s straight forward and intuitive if you’ve assembled other things such as a basic end table. What you should know: it does not come with instructions. It’s not hard to figure out but if you’re someone that needs instructions this product isn’t for you. That being said, if you see what you bought it’s not hard to look at the picture and assemble it. It does not come with the shelves. If you can’t buy them premise or make them then this product is not for you. Lastly, and this part is important to me, not all the pieces are straight after assembly. I used a level to mount the product on the wall and make each shelve straight. However, due to the factory produced screw grooves it is not perfectly straight. If you need it perfectly level looking this product is not for you. Refer to my pictures and you’ll see how the left bar looks crooked even though I mounted it level in every way. However, it gives it a more rustic, modern farmhouse feel that we wanted. Otherwise, a great product. I am still very happy for what we paid for. I would recommend the product and buy it again.

Great product!
Size: 4-tier, Style: wall mount&floor mount, Size: 4-tier, Style: wall mount&floor mount
This is my second time purchasing these shelves. They are easy to set up, come with all the screws, brackets, and drywall anchors (if needed). I definitely love the quality, look and versatility. Being that my ceiling is slanted I couldn’t mount them from there but easily mount them to the surface beneath the shelving. My husband loved my idea and how they turned out! Highly recommend!

No Instructions - Easy to build and study
Size: 4-tier, Style: wall mount&floor mount
I ordered 3, and my wife loves the look of them. They seem to support a decent amount of weight. I supervised my 7 year old (55 lbs) as she scaled a single shelf bracket up the wall after it was mounted, without the planks. You do need to have some amount of handiness to be looking at buying as it does not come assembled, and does not have the wood planks with it. A little learning curve I had. Keep the rods only hand snug, not tight, snug, and then as you put it up to the wall adjust as needed to get the heights and widths right to the opposing shelf. There is also only 8 pipe brackets to hold the shelves down (2 per shelf) and I did not realize this at first and assumed I had 16 (4 per shelf). I had to go back and fix.

Game changing storage!
Size: 4-tier, Style: wall mount&floor mount
I love the shelves. I got to use my own wood which was a reclaimed piece that I found and sanded and then stained. I'm so proud to see them on the shelves. It got so much clutter corralled from around the room and put in one place where it all looks good displayed together. The support pieces are very good quality and I found this to be very good value for the price. I'm very happy with this item.

Good all around, some imperfections on threads difficult to screw together
Size: 4-tier, Style: wall mount&floor mount
I received a complete product as advertised, it's a solid steel design with everything you need to mounted included. One small issue I encountered is that the pieces screw together but they wouldn't screw all the way it felt difficult and possibly if forced the steel might crack. Unfairly enough other pieces did completely screw in. So it's probably because of imperfections on the threads.
