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.

Excellent Warmer and the Rubber Pad is a very nice extra...
Color: 301 Black
... This really fits my cups perfectly... Just like it was made for these very cups. I wish I had found this one a long time ago and I am considering purchasing another one! Not Sure why they call it a "Coffee Cup Warmer", it would better known as a Beverage Warmer... but either way, it is a great unit and works great. Heat is great, I don't drink coffee, but it works equally well on Tea... This is an Excellent Value for the money.... Not throwing away cold tea and it stays HOT and mostly fresh! I wish I had found this a long time ago, much better than my older units. I will be purchasing another one in the near future! I think this unit is built well and will last a long time and I will... "Coffee Flavor" - No Thanks.... But it works great on HOT TEA! - Excellent Warmer and the Rubber Pad is a very nice extra... (It will help in not getting burned when I accidentally touch the heating surface by mistake! Excellent thought from the designer! You can adjust how hot to keep it and has a digital display to show the Temp that it is keeping the temperature of. I really like this item and I do highly recommend for Hot Tea and Coffee Drinkers, Works great for Hot Chocholate as well!... Doesn't let your drink get cold!

It's exactly what I was looking for!!
Color: 301 Pink, Color: 301 Pink
This one beats all the other mug warmers I researched on Amazon! That circular pad around the mug can come up and it's flat to the edges so I can sit my whole little flat bottom glass pot of tea directly on it and it keeps it hot, and I mean HOT all day! It also has 6 settings. The 130 barely keeps things warm for me but it goes up to 180 degrees! At 180 You can put your completely cold cup of tea that you left out all night and forgot about, turn this thing on and it will reheat your stale tea (that you probably shouldn't be drinking now) back up to pipping hot, steam coming off, you need to blow on it to take a sip levels! (Yes, I know you shouldn't drink tea that you left out all night but I'm just being real). If you want your hot drink to stay actually HOOOT but also have the option for it to be just lukewarm if that's you're thing, then this thing is for you! It also has a timer for shut off which is neat. The $20 spent on this has changed my life haha!

Upgrade from our last one, nice box, easy to read and adjust. Standard plug
Color: 301 Black, Color: 301 Black
One of our old coffee mug warmers finally died and we were looking for a replacement - this is way better than the old one. It comes in a nice printed box - so great for a gift. Standard AC plug and really easy to see button on front. This one shows the temperature and that's handy. It's just the right size for a good sized coffee mug and keeps it warm for hours - if the coffee lasts that long. It's easy to see that it's on so I can turn it off, but it also has auto off if you forget. I'm not really sure what the silicon topper is for, but it sure does look nice. Easy to clean when turned off and I have to say it's pretty professional looking. It's a 30 watt model so it draws enough energy to keep that coffee warm and can heat up to 180 - that's too hot for my use but I'm sure you can warm something else with it. Overall: A huge upgrade from our last one. Easier to read, use and clean.

Good mug warmer
Color: 301 Black
I like this mug warmer a lot. You can choose your temp and it keeps my tea very hot. I also like the auto shut off so I don't have the panic of "did I turn it off? My two minor complaints: 1. The rubber pad that comes with it doesn't stay in place and gets very hot. I just don't use it. 2. The controls are very sensitive. There are so many times that I pick up my mug and I change the temp or I change the timer because my finger brushed up against it. But, otherwise, it's a good value for the money.
