Klipsch KI-396-SMA-II Black 15" Commercial Loudspeaker at Vinyl Sound Toronto Canada

The KI-396-SMA-II is a high-output 15" 2-way commercial loudspeaker from Klipsch (Hope, Arkansas, USA), available at Vinyl Sound in Toronto, Canada. Part of the Klipsch KI Series Professional Installation line, this black-finish model features a 15" K-48-ST cast-frame woofer, a 3" K-691 titanium diaphragm compression driver mounted on a 90°x60° Tractrix "Mumps" Horn, and delivers a sensitivity of 101 dB with up to 127 dB maximum continuous SPL. Designed and manufactured in the USA using domestic and imported components, the KI-396-SMA-II is built for permanent installation in auditoriums, houses of worship, bars, music clubs, sports facilities, theme parks, and transportation hubs.

Tractrix "Mumps" Horn Technology and Pattern Control

The KI-396-SMA-II uses Klipsch's advanced Tractrix "Mumps" Horn, an evolved version of the original Tractrix geometry that adds controlled flare extensions at the horn mouth to improve coverage consistency across the operating bandwidth. Compared to earlier generations of Tractrix horns, the Mumps design exhibits tighter, more uniform pattern control, reducing the high-frequency beaming and coverage irregularities that occur as wavelengths become small relative to the horn aperture. The K-510 horn delivers 90° horizontal coverage (+/- 30°) from 400 Hz to 13 kHz and 60° vertical coverage (+/- 20°) from 1.6 kHz to 20 kHz. A Directivity Index of 8 dB (+/- 2 dB) and a Directivity Factor (Q) of 6.3 confirm disciplined high-frequency dispersion in demanding reverberant environments. Klipsch's modified Tractrix equation also allows the sound wave to exit the horn mouth with minimal back-reflections into the throat, directly lowering distortion and extending the flat response region beyond what conventional exponential or conical horns achieve.

High-Excursion 15" Woofer and Large-Format Compression Driver

The low-frequency section is driven by the K-48-ST, a 15" heavy-duty cast-frame woofer with a 3" (76.2 mm) voice coil and a 104-ounce (2.95 kg) magnet and motor assembly. The high-excursion design allows the woofer to maintain low distortion at sustained high-power inputs, producing deep, articulate bass reproduction from the compact trapezoidal enclosure. The high-frequency section uses the K-691 compression driver, featuring a 3" (76.2 mm) titanium diaphragm and a 64-ounce (1.82 kg) magnet structure, providing the headroom and thermal capacity required for continuous high-level output without driver fatigue or tonal compression. The two drivers are integrated via an internal high-current passive crossover operating at 1 kHz, with 12 dB/octave slopes on the low-frequency side and 18 dB/octave on the high-frequency side. The enclosure is CNC-fabricated from 3/4" 7-ply birch plywood with rabbet and dado joinery and a 1" MDF motorboard, ensuring structural rigidity and low cabinet resonance over the life of the installation.

Frequently Asked Questions

What is the Klipsch KI-396-SMA-II?

The Klipsch KI-396-SMA-II is a high-output 15" 2-way commercial loudspeaker from the Klipsch KI Series Professional Installation line, available in a black lacquer finish. It delivers 101 dB sensitivity, a 127 dB continuous maximum SPL, and a frequency response of 60 Hz to 18 kHz (+/- 3 dB), placing it among the most capable passive commercial loudspeakers in its enclosure class. The SMA-II designation indicates the multi-angle symmetrical trapezoidal cabinet format, which is optimised for permanent fixed installation, speaker clustering, and rigging in venues requiring sustained high output and precise coverage control.

How does the Klipsch KI-396-SMA-II compare to the JBL SRX835P?

The Klipsch KI-396-SMA-II is a passive permanent-installation loudspeaker, while the JBL SRX835P is a self-powered portable system. The KI-396-SMA-II achieves a higher sensitivity of 101 dB versus the SRX835P's 99 dB, and its Tractrix "Mumps" Horn delivers a measured Directivity Index of 8 dB, providing more consistent and predictable pattern control across the high-frequency range. The KI-396-SMA-II's 7-ply birch plywood enclosure and 16-point rigging system are engineered specifically for long-term fixed commercial use, offering greater installation flexibility and durability compared to the plastic cabinet of the SRX835P. For system designers working within an existing amplification and DSP infrastructure, the passive KI-396-SMA-II offers greater configurability, higher peak headroom at 133 dB, and more precise integration with professional signal chains.

Can the Klipsch KI-396-SMA-II be used as a full-range system without a subwoofer?

Yes, the KI-396-SMA-II operates effectively as a full-range loudspeaker without a subwoofer in most commercial installation contexts. Its frequency response extends to 60 Hz at +/- 3 dB, with usable output reaching -10 dB at 35 Hz, which covers speech intelligibility, background music, and live music program content in venues such as houses of worship, auditoriums, and performing arts spaces. For applications with heavy low-frequency demands, such as nightclub DJ systems or live rock music with sustained sub-60 Hz content, pairing with a Klipsch KI-Series subwoofer is recommended to maximise output and protect the woofer from thermal stress at high playback levels.

What is the Tractrix "Mumps" Horn in the Klipsch KI-396-SMA-II?

The Tractrix "Mumps" Horn is an evolved version of Klipsch's proprietary Tractrix horn geometry, incorporating controlled flare extensions at the horn mouth that improve coverage uniformity at higher frequencies compared to earlier Tractrix designs. In the KI-396-SMA-II, the K-510 Mumps Horn maintains a 90°x60° coverage pattern with greater consistency across the crossover region and upper frequency range, reducing the narrowing of dispersion that occurs in standard horns as frequency increases. The modified Tractrix equation simultaneously allows the compression driver's sound wave to exit the horn with minimal back-reflections, lowering distortion and maintaining flat frequency response characteristics even at high continuous output levels.

Where can I buy the Klipsch KI-396-SMA-II in Toronto or Canada?

The Klipsch KI-396-SMA-II is available at Vinyl Sound, an authorised Klipsch dealer located in Toronto, Canada. Vinyl Sound serves customers across the Greater Toronto Area and ships throughout Canada, providing access to Klipsch's complete KI Series professional installation loudspeaker range. Purchasing from an authorised Canadian dealer ensures full manufacturer warranty coverage and access to professional system design and installation support.

What amplifier power does the Klipsch KI-396-SMA-II require?

Klipsch recommends pairing the KI-396-SMA-II with an amplifier providing headroom of approximately twice the speaker's continuous power rating, meaning at least 1200 watts into 8 ohms for optimal dynamic performance. The nominal impedance is 8 ohms, with a minimum of 5.1 ohms at 112 Hz, making the speaker compatible with standard 2-channel or 4-channel professional amplifiers from brands such as Crown, QSC, and Lab.gruppen. Klipsch cautions that both overpowering beyond 3 dB above rated handling and underpowering with a clipping amplifier can cause driver damage, and recommends amplifier headroom be calculated based on twice the published numerical power rating of the speaker.

What types of venues is the Klipsch KI-396-SMA-II designed for?

The Klipsch KI-396-SMA-II is engineered for demanding permanent-installation environments that require sustained high SPL and controlled dispersion. Klipsch identifies the primary applications as performing spaces, auditoriums, houses of worship, bars and music clubs, small to medium sports facilities, theme parks and leisure venues, and transportation facilities. The 22.5° symmetrical trapezoidal cabinet enables tight horizontal clustering and left-right mirror-image configurations, making the KI-396-SMA-II particularly well suited to above-stage flown arrays, corner clusters, and distributed coverage systems where precise pattern control across multiple units is critical to system performance.

Can the Klipsch KI-396-SMA-II be rigged or flown overhead?

Yes, the KI-396-SMA-II is purpose-built for overhead rigging and flying applications. The enclosure includes sixteen 3/8"-16 threaded flypoints, four per top, bottom, and each side panel, providing comprehensive rigging attachment options compatible with standard rigging bars, array hardware, and truss systems. C-bracket mounting points on the top and bottom panels accommodate standard commercial speaker bracket hardware for wall or ceiling surface mounting. All rigging and flying installations must be performed by qualified professionals in accordance with applicable load ratings, rigging standards, and local building codes.

Slow, sorry but good
Format: Kindle
This was a slow moving book. Lots of character pov chapters, lots of superfluous descriptions and endless courtly appearances stalled this book to start. Once you get into the heart of the story, it takes off. Before you know it the book is done. My favorite character is Reyna. She is so strong. She is true to herself. She gets into a lot of trouble with her headstrong ways but it's entertaining. I have high hopes for Lorcan. He is honorable to a fault. Thane had turned out to be better than I thought but i still don't like him. Eislin is useless. Great plot twists at the end. I'm looking forward too book 2.

Very detailed! Beautiful world building! Strong Heroine!
Format: Kindle
Starts off a little slow and confusing with different POV’s, but starts to all come together towards the middle to make an elaborate plot line and makes it all worth it. Beautiful world building and attention to detail as well as great writing. The cliffhanger was gut wrenching! Can’t wait for the next book!

Interesting
Format: Kindle
This was a very captivating book once you got into it thoroughly. But the third person perspective was a bit hard to get used to. But as you got into it and followed the different characters, it was interesting and filled with intrigue, conflict and forbidden love. I can’t wait to read the next one and to complete the series.

OUTSTANDING
Format: Kindle
This was very, very good. The world is vast and characters are complex. There is a good plot with a whole lot going on. This is well written. Good twists and turns and some heart breaking moments. You will love these characters, they have heart and loyalty. I am hoping that there will be several more books. We've yet to see anything from the Sea Court but only a mention of them here and there. The Wood Court was given a quick couple of scenes, and only as far as some warriors, we've yet to enter their court and the Shadow Court, I'm not sure if they will be a force for good or bad, but they definitely will play a much bigger role moving forward. This is primarily the Ice and Air Courts. Told in multiple views, which I loved, it gives you a chance to see things from different eyes. There's alot of political maneuvering and deception. I loved it and will pick up the next book as it becomes available. If you like The Fae and the courts, you should love this. I think the author has mucn in store for us.

Definitely worth the read!
Format: Kindle
After taking a deep breath and taking in that wicked twist of an ending, I have finally composed myself. My first thought when I started this book was that I love Reyna's character. I was intrigued by her connection with her familiar and the Ruin that is plaguing her land. It came as no surprise that she took her sister's place in an attempt to protect her. When they reach the Air Court everything slows down. This is where it was iffy for me. First of all, I like multiple POV's in books however 7 is a bit much. It starts to interrupt the story line. I felt like I was finally making progress connecting with one character, then it was switched to another person. I felt they all had necessary or pertinent information but not necessarily were they all POV worthy. The only other thing that annoyed me was that Reyna constantly was " trapped." She would rush off without thinking, only to need rescuing. She is brilliant in a fight, but she really doesn't think through anything. Lorcan is amazing. I know he might be on the "bad" list, but his background is so interesting. Eislyn(Reyna's sister) is really so sweet, but calculating. I enjoyed her and Thane's dialogue. The author did an amazing job with the imagery in this book. Everything was so detailed it was easy to fall into the scene. I love unexpected twists and while part of the ending I expected, I wasn't expecting how it took place. All in all, I found it very entertaining and I am very invested in continuing this series. Favorite quotes: "The truth may be twisted but never false." "Who was she if she was not the enemy of the Air Court? What was her purpose of she no longer has that?" "In a war-torn land, love was always a lie."
