The LSA-10 Signature is an amazing value competing with any monitors that we have heard under $5000.00 a pair. It offers compelling value at our Internet Direct price.

Kemper Holt   "The LSA 10 Signatures and Emerald Physics electronics which were plugged into Core Power Technologies balanced power 1800 conditioner combined for an outstanding system. One of the few systems with substantial front to back depth, it also demonstrated a wide stage with pinpoint imaging, the speakers completely disappeared, vocals were wonderful, but the most stunning surprise about the system was the low bass extension, power, impact, and ability to pressurize the room, it rivalled many small floorstanders with extension down to 35 Hz, a passive radiator on the rear of the monitor is the secret ingredient to the bass proficiency. Every person who came in and sat down to listen when I was there asked if the floorstanders were playing, and everyone was astounded that only the monitors were making such full range music."

The LSA-10 Signature monitor uses a custom LSA 1” silk dome tweeter with a compact neodymium XBL2 magnet structure and a shallow waveguide to better integrate with the woofer, a single black anodized LSA custom aluminum 6.5” XBL2  woofer, and a single rear mounted 5” x 7” sub bass radiator.  It uses a computer designed 4th order Linkwitz Riley acoustic crossover with an easy 12 ohm impedance rating (see note below). The LSA-10 Signature has an in-room response from 38Hz to 20 kHz +/-3dB. The LSA-10 Signatures are available in a chocolate Rosewood Satin wood veneer with magnetically attached grille.

The LSA-10

The LSA-10 Signature was awarded Best in Class at their Axpona intro by Audio Bacon. They said:

"With so many rooms to cover, when a reviewer revisits a room – there’s something special in the air. The Underwood HiFi room was one of two of my revisits at AXPONA (the other being Verity Audio). I just had to reaffirm what I was hearing – as the pricing was extremely attractive. This entire system clocks in under $3,500."

"As far as sheer musical enjoyment, this room made it in my top 3. First, the imaging capabilities of these LSA-10 loudspeakers are astounding. You get perfectly positioned instruments and confidently grounded vocals. Secondly, a lifelike body and tone encompass all the listening sessions. Everything was believably present. In essence, it sounded like warmblooded performers were molded and placed three-dimensionally into the room."

"Usually, this would mean softer highs and veiled details – but this isn’t the case. Cymbals and violins still have a sufficient amount of vibrancy while percussions are pronounced with weight and gravitas. It was difficult to imagine anyone not enjoying this sound."

"Best in class and probably a best-kept secret in HiFi. You really don’t need to spend a lot of money for really good sound. If you ever have a chance to listen to this setup at future shows – it’ll be worth your time."

"Needless to say, I’ve requested a review unit and will be taking a closer look in the upcoming months."

A note about speaker sensitivity

The design philosophy on our monitors was to make a speaker with amazing bass output. Bass that outperforms many much larger floor speakers. As in any speaker the design trade offs are low bass output versus box size and efficiency. Given that we have a monitor with a moderate sized box and decided to offer far better bass than any other speaker that we know of in the price and size range we had to compromise on the efficiency. However, unlike other small inefficient speakers our impedance is a super easy 12 ohm load that allows even smaller amps at 40 watts to play the speakers very loud. Most monitors have far lower impedances that places a strain on your amp and limits ultimate output. Our monitors rock, even with smaller amps.

"Overwhelmingly full sound, the new speakers from LSA were assembled only one day before the show. Breaking in wasn’t even option, yet the crowds were set back in their seats with mouths agape. Prodigious was the bass and scale of these little wonders."
