The Alumina System is the perfect mid-priced, but high performance, home theater speaker system. It truly produces "large" sound without consuming the room...or your wallet.
And you don't need to add a subwoofer to this setup - it comes with two of them built in!
This is a five-cabinet surround sound system that was used as a demo in our studio. It uses two(2) AlumiFront speakers with built-in subwoofers and three(3) AlumiSat speakers for center channel and L/R surround sound. It is in excellent condition and in perfect working order. There are some minor scuffs on one of the AlumiSat units.
The AlumiFront is a surprisingly strong, full-range,
three chamber minitower. Its smooth upper frequency response
comes from a 1" pure aluminum cone tweeter with a gently rounded,
horn loaded face plate. This tweeter also uses a high energy
neodymium magnet that is 20 times stronger than ceramic magnets.
Ferrofluid cooling adds high dynamics and stronger power handling.
The 6-1/2" woofer is also quite remarkable. Its aluminum cone is
very stiff and light producing excellent transient response in
the upper midrange. And its huge 20oz. double magnet system
coupled with an "Omniflex" rubber surround produce a bass response
that rivals most 10" woofers.
But that's not all! The AlumiFront hides a secret
weapon inside.....a very powerful 8" subwoofer. This dual
chamber forth-order band pass design produces room shaking bass
which is vented out the back of the cabinet through a computer
optimized flared port. And since the AlumiFront is
biampable, its subwoofer can be driven by a separate amplifier
for even greater control and impact.
At only 9-1/2" wide the AlumiFront will definitely
The AlumiSat may fit on a bookshelf, but don't call
it a bookshelf speaker. It is a full-range mighty mite capable of
sounding very clean at high volumes. All the sophistication used
in D+S's large systems is still used in this compact gem.
The AlumiSat uses the same outstanding 1" tweeter
and 6-1/2" midbass driver as the AlumiFront above
and is also vented with a computer optimized flared port. Using
identical drivers in all the speakers of a home theater eliminates
any timber matching problems. In other words, when an airplane
flys overhead in a movie scene, it sounds the same behind you as
is did in front of you.
