Living Sounds Audio (The LSA Group)

Underwood Hifi owns LSA and we are selling LSA exclusively factory direct. This allows us to dramatically lower the selling prices of our excellent speakers and electronics.
 
Our new LSA Signature 50 is NOW SHIPPING. We think it sets a new standard in a high performance affordable monitor. Below is a first shot of the finished speakers. Our competitors offer 6-8 pound speakers in cheap vinyl boxes. This is a 23 pound, rear ported, beautiful real wood enclosure with leather top and fronts. It features superb drivers and custom crossovers.
These speakers retail at $599.00 Internet Direct and are being introduced at $499.00 + freight for a pair.

The intro price will run thru May and then orders placed after June 1st go to $599.00
We are currently sold out but orders placed this month will get the $499.00 deal & not be charged until they ship in early July
Even we are shocked at the 38Hz in room bass response

“wow, just wow.”

What does that really mean anyway? It leads to so many more questions. In all seriousness,
the new Signature 50 speakers from LSA (available only online from Underwood Hifi) offer
tremendous value, performance, and build quality for $599/pair.

Here is an initial user feedback:

"I know you’re a busy man, so will keep this review of your LSA 50 brief: 
 
Not even broken in yet, the LSA 50’s easily meet, and in many respects surpass, $2000-3000 floorstanding towers I’ve heard. (I’ve heard a lot of them). An incredible feat. 
 
Key features: 
 
-A natural, tonally correct, authentic sounds. Violins sound fleshy and real, not thin. Cellos sound resonant and organic. Percussion sounds like it’s in the room 
 
-Noticeably Dynamic. The speakers have presence, “slam”, immediacy, pop. This makes music sound real, alive, dynamic and lively. 
 
-Details: I can hear deeper into my favorite test tracks, but the detail never comes at the expense of sounding natural, real, and non-fatiguing. Never harsh, but all the details come out with 3D realism. 
 
-Imaging. Even without ideal placement, the imaging is top notch. Spacious, airy, yet the voice is grounded and centered in the middle. 
 
-Bass. Have to keep checking that the sub is not turned on!  The bass is that good. Quick, clean, focused, and deep. Sounds like a much larger speaker and without roominess. I understand this will only improve with break-in, which has not yet happened."

The LSA Signature 50 speaker is a compact stand mount 2-way bass reflex speaker with a 6.5 inch treated paper cone woofer and a low distortion high-resolution 28mm silk dome tweeter integrated with a unique quasi-transient perfect passive crossover that provides a realistic sense of rhythm and dynamics for percussion and drums. 

In the first review Tone Audio said:

"Because the Signatures accomplish so much, it’s truly tough to find fault – remember this is a $600 pair of speakers. In 40 years, only the Magnepan SMG and Vandersteen 1 (back when they were only about $900 a pair) have offered this much sheer musical enjoyment for such a modest investment. Putting the LSA 50 Signatures in the same sentence with these two classic speakers is the highest compliment I can give them."

The crossover components used feature high quality film capacitors as well as utilizing pure copper, large-gauge inductors and premium audio grade wire wound resistors (not white “cement” type resistors). 

The unique quasi-transient perfect crossover means that both the woofer and tweeter are in the same absolute phase (both push out at the same time on a sharp pulse) and time-aligned, and thus render acoustic peaks and crescendos with a minimum of time-smear for crisp and clear cymbals, guitar plucks, piano key strikes, drum rimshots, and standup bass plucks with precision and lifelike realism. 

The time-alignment also provides a wide soundstage and accurate placement of the stereo image.  The quasi-anechoic bass extension is 38Hz at -3dB.  In-room bass extension will likely be deeper with room modes. 

The top end response exceeds 22kHz with a crossover situated at 3.8kHz to provide the required time alignment and phase integration for a 60 degree wide polar response that varies by less than 2dB.  Amazing results for a loudspeaker in this price class – or far above.

 The natural and lifelike voicing has been extensively optimized over countless hours of critical listening sessions provides an enjoyable and fatigue free experience. Our Voicing Team has decades of experience and they have applied sound practices and results in this loudspeaker.

 The LSA Signature 50 is a speaker that you will want to re-listen to your entire music collection again because it is that good and just plain fun to listen to.

LSA 20 Statements with grills on

Read the Dec 2020 Stereotimes review of the LSA-20 Signatures. Terry London sums with:


"The LSA 20 Signature offers a superlative level of quality in both appearance and performance.  It is a small footprint floor-stander that is elegant visually and gorgeously clad in a chocolate Rosewood matched veneer that will create the appearance of a much more expensive/upscale speaker.
It creates the reference level spatiality of the finest two-way monitors. The quality of the tweeter and midrange drivers offers pristine, natural tonality/colors and see-through transparency that allows all the micro-details to be easily heard. Yet, the overall transient speed and dynamics with taut, powerful, and harmonically accurate bottom end extension give this speaker the ultimate ability to anchor any music to a rock-solid foundation that realistically supports the upper frequencies. And to sell this speaker for $2,299 (for a limited time only) makes the LSA 20 Signature one of the great bargains going in today’s high-end audio market. If for some reason, after you purchase a pair of the LSA 20 Signature speakers, you are not satisfied with them, the very fair return policy is a 10% restocking fee and shipping costs back to Underwood Hi-fi, Inc., After all, I shared in this review regarding the virtues of the LSA 20 Signature it will make sense that I will be purchasing the review pair to have in my stable of speakers for my different systems."

In their year end "Best of" 2020 edition Part Time Audiophile named the LSA-20 Statements one of their best of 2020 speakers. They said:
"Living Sounds Audio, now owned by Underwood Hi-Fi, is really impressing the staff here over the last year with its growing stable of excellent products, and the Statement 20 is a prime example of why.
For a mere $6K you get a big, beautiful speaker (BBS?) that is equally adept at playing all sorts of music. “They are beautiful to behold, and also possess a sonic ‘rightness’ that both excites and soothes [our] spirit.”
The LSA-20 Statement is on sale thru the end of the year at only $3299.00 delivered for the pair.

In the July 2020 review in Parttime Audiophile they sum with:
"They are beautiful to behold, and also possess a sonic “rightness” that both excites and soothes my spirit. I have no doubt that Walter Liederman has achieved his goal of offering a highly satisfying, if not near perfectionist, product to a price level within reach of many regular, hard-working audio enthusiasts."

"That such a lovely and accomplished full-range tower speaker can be offered at a price just shy of $6k is a testament to what can be achieved in today’s high-end marketplace. What a balm in today’s troubled world!"

2019 Axpona show award as one of the best sounds at the show on the LSA speaker introduction

The LSA speakers are amazingly good values at the new Direct prices. The original line received superb reviews. The new 2019 line is a dramatic upgrade with all custom drivers, upgraded cabinets and better crossovers.

The new 2019 line uses the patented XBL2 drivers. These drivers allow for more linearity and lower distortion at all levels. The new products were designed to compete with high end speakers that sell for 3 times their price thru retail dealers. They offer serious value at our Internet Direct pricing. The original line had Standard, Signature and Statement models. This new line has only 20 Signature and Statement versions. The Signatures are a step up over the original Statement versions and the Statements offer untouched performance & value at our selling prices. Target models were 2-3 times our prices.


The LSA-20 Statements have a beautiful upgraded Chocolate Rosewood lacquer gloss finish.

XBL is a patented technology that is well proven with tens of millions of drivers worldwide.  The dual gap architecture used in our transducers provides extremely high output, very wide bandwidth, and exceptionally low THD. And by using aluminum drivers and formers we get additional cooling that allows for much longer throw giving us more output with lower bass frequency capability and along with lower distortion.


The LSA-10 Signature are sold out. The new LSA Signature 80 below at $1499.00 a pair retail is due in late April. They will be introduced at $1299.00 for the pair.

Signature 80

$1499.00 pair

First photo of Signature 80

The Signature 80 uses a 7" metal cone woofer and a new 3" planar ribbon tweeter with custom wave guide. Our custom crossover is superb.

The Living Sounds Audio (LSA) Signature 80 speaker is a ported 2-way reference monitor designed to provide an accurate and natural sounding presentation with superb resolution and low distortion. We utilize a state of the art planar tweeter in a custom CNC’d aluminum waveguide. We couple the tweeter to a low distortion 7" aluminum cone woofer. These drivers are all housed in a beautiful rosewood veneer cabinet with deep front bevels to reduce diffraction effects.  The waveguide and crossover provide a wide angle sweet spot of over 60 degrees with essentially a uniform response and only down -5dB over 90 deg. The bespoke crossover is voiced to provide a smooth and natural transition at 3.5kHz and utilizes a custom PCB with high quality film caps and pure copper wire inductors for resolving high resolution details and to maximize bass impact. The attention to detail and high quality components are further evidenced by a custom CNC’d binding post plate fitted with premium Viborg 5-way gold plated copper binding posts.

Preliminary specs
Frequency response: 35Hz-25KHz
Sensitivity: 86.5dB
Impedance: 8 ohms

Crossover: 3500Hz
Recommended power: 30-150 watts

15.75" high
