These SONICS Electronix Alegria's (German Hifi AudioPhysic) are sincerely barely used...The cabinets are a gorgeous Birdseye Maple. I have owned the Sonics for the last 3 years. I personally bought them new in the box and still have the original packing and boxes...I had 2 REL "Sho 3" subs (sold) so they were never abused and the bass was always at a minimum. I personally guarantee that these come to you as "Brand New" in the original box and there is NOT a scratch/mark/issue with either one. I am 56, no kids at home, no pets or smoking!  They were over $20,000 with the Birdseye maple wood upgrade and were a big hit overseas as the Designer/Engineer "Joachim Gerhard" was originally from Germany and as I have heard a very well known Engineer. The sounds of piano and guitar/voice is insane, low end is def there but subs def help. I also have a pair of 10' "MIT 3.5s Magnum" cables and one 8'(brand new) center cable bought last year and MINT/new condition as well. Separate AudiogoN ad for those but will do a "package deal" and you can come over if nearby and listen anytime!  I also have the original floor spikes (pictured) they were never used as you can see they are on a really nice (rug) bath carpet...They are not Yellow, it is just the pic they are natural wood tone. The following is the stats on these to the best of my knowledge, all I know is that they sound absolutely amazing!!! To upgrade from these speakers would be anything but ridiculous, very few speakers out there that will compete for the $$ I am asking :) I am running 400 watts class "D" amp (Arcam) and can't imagine what these would sound like with Monoblocks...Make an offer, this is NOT a fire sale just don't use enough to value the past purchase :( We watch movies prob once a week listening to these in the living room when we get a chance to chillout!

This speaker is very easy to drive and sounds great ! 

These speakers sold at $20,000.00+ in the birds-eye maple!


Pure listening pleasure.... 
The Allegria is a 3-way floor standing bass reflex speaker using modular cabinet technology and new drivers developed for low distortion and flat frequency response. The cabinets employ a very intricate internal construction and each module is decoupled with resonance control devices.

Sound Quality: 
Sonics puts high emphasis on spatial presentation, neutrality, resolution and dynamics. The Alegria's bass reproduction is clearly defined, the mid-range is exceptionally open and natural, while the high frequency range reveals new details, without any indication of sharpness. Outstanding reproduction of micro details gives the Allegria a warm, 3-dimensional presentation.

The Ribbon Tweeter: 
The high resolution capacity for ribbon tweeter's has been acknowledged for decades. However, ribbons could not match the dynamics and low distortion of highly developed coil tweeter technology. New developments in the field of materials and construction have overcome these disadvantages. Its moving mass is only 35 mG, a tenth of the mass of a 25mm dome tweeter, yet, the increased surface area over a conventional tweeter results in an output of 98dB. The result is increased output capacity while distortions are reduced to an un-measurable level. This ribbon's output is so high that, unlike dome tweeters, it is not the limiting component in the overall output of the speaker.

Mid Range Driver: 
Historically, listening trials and measurements show paper to be the optimal material for mid-range drivers when transparency, dynamics and neutrality are the goal. While similar results are obtainable with specialized metal alloys, those drivers are less efficient and require complicated crossovers. The Allegria mid range contains the latest developments in paper cone technology. A damping coating is applied to the back of the cone and Nextel, a ceramic based coating, is applied to the front. This driver is linear up to 12 kHz but is crossed over at 2.35 kHz. so it operates in its most linear and distortion free region. The result is a particularly fast mid-range with a distortion factor reduced to an unmeasured level.

The bass region is handled by a metal cone woofer developed specifically for the Allegria. Designed to be exceptionally stable, it easily withstands high acceleration forces and has a cone shape that eliminates resonance in its frequency range. This driver is capable of enormous acoustic pressure without compression or distortion and delivers well defined bass with exceptional clarity. Its speed and low mass ensure high resolution even at low volumes.

Due to its low price and easy machine-ability, MDF (medium density fiberboard) has established itself as the primary material for speaker enclosures. As for performance however, due to its weight and flexibility, internal sound pressure turns the entire cabinet into a high distortion speaker. To avoid this the Allegria is built from a mix of 30mm birch plywood and 30mm HDF with elaborate dovetail joints at optimal places. The unpleasant sound associated with MDF is avoided. Woofer, mid-range and tweeter housings are decoupled to prevent bleed-through. To maximize stereo imaging all cabinets have a minimal front surface area. Up to 6 spikes can be mounted into the base offering various coupling options.

Sonics possesses special know-how in the area of crossover design. As part of a two-year research program all critical parameters were computer simulated and measured. The best components (condensers, coils, resistors, wiring, and plugs) were also tested and auditioned. An optimal algorithm was developed for the Allegria and the final configuration was determined through listening. Like other Sonics models, we used our DC module, transitional filter and back EMF damping. The technical advantages of our crossover are: linear frequency, phase-locked coupling with the cabinet, high slope between mid-range and tweeter for minimal acoustical interference and exceptional slew rate. All this results in exemplary sound quality with impressive rendition of soundstage width, depth and height, focus and transparency. The speaker also presents a friendly load to enjoy with both tube and low-wattage Class A amplifiers.

Al Writes: 


I use the same ribbon in my speakers that I build and sell is a very good tweeter and a very good alternative...

I responded: Yes, It sounds amazing! Never heard piano like that before and voice is spot on!!!
