Scan-Speak Discovery 30W 12" Subwoofer Kit

Scan-Speak 30W/4558T 12" Subwoofer + 30W/0-00 12" Passive Radiator + SpeakerPower Amp with a 10% discount

Audiophile performance at an affordable price! Scan-Speak Discovery drivers are produced and engineered in Denmark, but at much more attractive prices. 

This system uses the long stroke 12" subwoofer 30W/4558T. This woofer features a rigid aluminum cone with rubber surround. The 12.5mm linear excursion ensures good control at very low frequencies. A 2" diameter voice coil provides good power handling and fast response. The large magnet provides good efficiency and tight control.

Scan-Speak subwoofers make great replacements for old drivers in a variety of audio gear and are also fantastic for new designs. Hi-tech fiberglass/ paper cones combine natural warmth and sound quality with superb detail. Large vented magnet assemblies and extended voice coils enable long-throw performance and strong bass. These versatile subs are also rugged enough to be used in dipole and automotive infinite baffle applications.

Instead of a port, a passive radiator is used to tune the enclosure. The passive adds output and eliminates noises associated with using a port. For low frequencies in smaller boxes, a proper sized port would be too long to fit in the enclosure. The passive radiator eliminates many undesirable effects of a port.

Blending the 30W Kit into your stereo system is a breeze thanks to the Speaker Power line of subwoofer plate amplifiers.

Why use SpeakerPower?

There are many unique benefits to working with SpeakerPower:

• Designed, assembled and tested in Santa Ana California. The 2400W-6000W amplifiers are made entirely with local vendors and qualify for MADE IN USA.
• Lead times are short. Amplifiers are built to order as you need them. Quantity commitments are small.
• Custom faceplates, silkscreens and other features are easily accommodated.
• Some models have UL/CSA approval as a standalone product. This means you don't have to pay for an expensive UL investigation, quarterly inspections of your manufacturing, calibration of test equipment etc etc. The combination cUL mark is already screened on the faceplate.
• SpeakerPower has over 30 years experience designing and manufacturing loudspeakers and amplifiers for some of the biggest names in the business.

So while piecing together your own amp may appear to be less expensive, when you consider the total cost of time to market, UL/CSA, inventory, engineering etc you will find the SpeakerPower turnkey solution to be very competitive.
