RE Audio SRI10D2

10" Dual 2 ohm SRi Series Subwoofer


We apologize

SRX Performance for a Fraction of the Price
Getting high performance doesn't always have to be difficult and expensive. The RE Audio SRI10D2 is a Sonic Exclusive item that brings subwoofer performance to the next level. At it's core, the SRi is a SRX subwoofer from RE Audio. That means big bass and solid power, even if the RMS only 300 watts. While RE Audio specifically rates this woofer at 300 watts, there are many applications in which this woofer is capable of handling far over 300 watts. Being an SRX woofer at its center, the RE Audio SRi has a different basket and a slightly different look than that SRX sub. However, the performance is the same. SRX performance with money left over. Thats what the SRi is all about.

Subwoofer Specifications

Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
300 watts
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
2 ohms
Xmax (millimeters)
Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.
18 mm
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Round / Circle
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Kraft Pulp
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Subwoofer Grille
Most subwoofers are able to accommodate a universal grille; however, some subs include a grille and others have a specific, optional grille available for purchase separately. If "yes", then the subwoofer includes a grille. If "optional (sold separately)" the matching grille will need to be purchased in addition to the sub.
Re-Cone Kit Available
Some higher end subwoofers have replaceable cone assemblies. In case of a blown woofer, a recone kit allows for a simple replacement, as opposed to purchasing an entire new subwoofer.

Recommended Enclosure Specifications

Recommended Enclosure Type
This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Ported / Vented
Minimum Sealed Box Volume
This value indicates the minimum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
0.35 cubic feet
Maximum Sealed Box Volume
This value indicates the maximum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
0.5 cubic feet
Minimum Ported Box Volume
This value indicates the minimum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
0.65 cubic feet
Maximum Ported Box Volume
This value indicates the maximum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.0 cubic feet
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
Cutout Diameter
The actual diameter of the hole you will need to cut out if you are creating a new mounting location for this speaker, or if you are mounting a subwoofer in a box.
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

Awesome subwoofer for the price!

This subwoofer is an awesome subwoofer to have for the price. For another subwoofer with the same specs and quality will easily be twice the price! Looks like the price is slowly going back up so you all better get one soon.

Best bang for your buck period!!!!

November 30, 2010

Just got these today and stuck them in a ported box 2 cubes ported to 33 hz. Had em turned down to break them in but the sound quality was great. Very crisp clean tone and they definitely showed potential to get low. Running two of these together to reach a 2 ohm load to amp. Re-makes a good product and these won't stay cheap very long so get yours while they last.

amazing sound, amazing power handling, amazing price.

December 7, 2010

For 57 bucks, you cannot find and equivalent sub. i owned two Cerwin Vega vmax 15s (500 RMS each in a 5 cubic feet ported box), had to sell them since they wouldnt fit in my truck (old car was bigger). So I went with RE since I heard good things. Now its very hard for 2 10s in a sealed box to compare to even 1 15, but I don't miss much. That's a huge statement for something so small and so cheap. I wish I could put 50 stars on the value. If your thinkin about it, get em! PS- the only reason i gave 3 in look/design is because of the made in china sticker, and the pressed steel basket. my old cv's had a very nice quality basket, this one just looks cheap. but its got it where it counts.

This is the most BANG for your buck hands down

December 3, 2010

I have a Alpine Type R and now this RE sub in my truck, I figured it would complement my awesome Type R, but it is actually just as loud if not louder than my Type R which I could not believe. A type R is over twice as much as the RE and this sounds just as good. I HIGHLY RECOMMEND THIS to any 1 wanting a awesome sub on a low budget. And I ran it at 300 watts 4 ohm load off a alpine amp i did not over power it to make it sound loud so im amazed.
