Andromeda Design XPE loudspeakers

Andromeda design currently makes one loudspeaker model

This is  a real full range soundmachine, with virtually no loss of output at 20  HZ and extending to well above 20 kHz, no subwoofers needed with this model, it will play at very high SPL s without noticeable distortion, which was/is a design goal

This model can be ordered with 2 different types of tweeters, one is a softdome and one is a ringradiator soft dome tweeter

The previous has a straight output on axxis of well over 20 kHz, and the latter has a gradual downslope to about -3 db at 20 kHz

We prefer a -3 db downslope

Freq response is +- 1,5 db 400 hz 13 kHz, measured at 1/6 oct and this is a average room response not measured in an anechoic situation  in which we dont listen anyway

Bass extension/tuning is largely done by wooferspecs/volume and expirience, the woofers fire sideways in mirror image

There are 2 finishes, one is the finish shown in the picture, the other one is a model which has beautiful thin wooden inlays in the side of the speaker, virtually any colour can be implemented

The first is 2 times spraypainted/polished, the second is 7 times spraypainted/polished to a mirror finish

Dimensions are incl footers: height 1345 mm  wide 300 mm deep 670 mm , with sloping front front for improved dispersion

The speakers come with professional wooden packaging and can be wheeled out of the crate

Price is 49.900 euro a pair and the luxury version is 53.200 euro a pair these are consumer prices incl VAT

Those who are after a natural,highly accurate, real full range soundexpirience will enjoy the XPE loudspeakerdesign

Designed to compete with anything on the market regardless of price ( comparable systemsize/membranesurface )

This design is a ultra stiff /non resonant monocoque, 4 way loudspeaker in MTM configuration

Its made from 40 mm HPL solid plates (phenolic resin composite) over 250 kg a piece , braced inside with HPL as well

The mid- unit  membranes are made of stiff propietary natural  fibers which have a  natural presentation

The woofers are made in Germany and  are 11 inch, 12 inch respectively,  stiff non resonant membranes with a natural presentation, and a very low resonance freq

Tweeters used are multiple in this design as described elsewhere , but as with all other components are chosen for their excellent specs and  natural  presentation never harsh, always without any listening fatigue

The speakers stand on top of the line finite element cerabase classic devices, 70 mm wide at the bottom so they will not leave an imprint  on solid wooden floors, distortion through speaker resonance has become a thing of the past with the XPE design at whatever SPL

Regarding basstuning for different environments /rooms , the bassreflex system consists of 2 pipes which can be used as a whole or used seperately, one can either use the short or long version, for difficult environments the system can function as a closed system in which the reflex opening can be closed all together

The bassreflex pipes are machined out of high grade aluminium alloy and then clear anodized

Another design feature what we practice is aiming at a high overall efficiency +- 93 db and high impedance X over design

The XPE ls is therefore easy to drive and  will show its full potential with 18-20 watts minimum , making it a good partner for lamm set amps 18 watt

Or any 18 watt amp  or higher rated power/integrated amplifier, be it tube or solid state, we currently use Convergent pre /poweramp with KT 120 tubes

It is has been tested with 300 B(8 watts) amplification but feel just a little short on control/dynamics
