Overview
Velocity Overdrive Speakers Are the Absolute Top of the Line With Both the Highest Output as Well as the Best Sound Quality
These speakers deliver on a true live concert experience that just can not be found in any other speaker set. Velocity OverDrive is as good as it gets. This full 4 speaker system has all of the best components and is tuned for you and ready to rock.
Velocity R65 Neo 6.5” Midranges
The snap of the midbass is sharp and authoritative. The fairing mids (R65 Neo) are perfectly matched for the available air space in fairing speaker pods of ‘14 and later Street Glides and Road Glides. The upper frequency response is smooth and warm sounding thanks to the light weight yet rigid impregnated cone material. The cone geometry of these speakers is far superior to other pro audio type midranges on the market. The R65 Neo has a very unusual upper mid-range and high-frequency efficiency that makes it much louder when paired with horn-loaded tweeters than all other mid-range speakers. This is because the mid-range can couple to the tweeters output without shifts and gaps in phase or frequency response.
Velocity RZ75H Compression Horn Tweeters
The first thing that you will notice about this speaker system is that the compression horn tweeters are silky smooth sounding and do not have that typical harsh horn sound at all. They are sparkly and lively sounding. These horns are very much capable of playing louder than all of the other speakers on the bike but they are also level matched, phase matched, and tuned to perfectly compliment the Velocity mid-ranges, making the combination of the two speakers as loud and beautiful sounding as can be.
Velocity RZA1000.4 amplifier
The RZA1000.4 is the very best-sounding amplifier made specifically for Harley use. This amplifier has better speaker cone control at high volumes for better bass, and far better high frequency fidelity than other amplifiers. Natively compatible with factory Harley radios and aftermarket radios alike, the RZA1000.4 has a super wide range input (.41 to 10 volts) that is balanced so that it can accept anything from a standard line level RCA to a high voltage speaker level input directly from a factory radio. And it does this without the need for any noisy line levelers. This amplifier uses a far superior internal power supply to other amplifiers and can sustain extreme performance where other amplifiers just run out of gas and clip or drop in volume. This is a beast of an amplifier in a small footprint. This amplifier features a full chassis heat sink for more performance in a much smaller size package. The full chassis heat sink also allows for the amplifier to be mounted in any position and to keep cool even on the hottest summer days.
Maestro DSR1 DSP
This kit uses the awesome Maestro DSR1 digital sound processor to seamlessly integrate the aftermarket amplifiers and speakers with your factory or aftermarket Harely radio. Is is industry standard to use this sound processor to make the factory Harley radio perform and integrate with aftermarket speakers and amplifiers, but i also plays a critical role in systems with aftermarket radios as well.
Optional Plug & Play Connections and Harnesses
All of the wire harnesses and connections that you will need to install this system. This includes a fully loomed OFC 8 gauge power harness, waterproof fuse holder (pre-installed), an amplifier mounting pad, a fairing speaker output harness with service disconnects, a rear speaker output harness for the saddlebags with service disconnects in the fainting and at both bags as well as at each lid inside the bags, Plug and play crossovers (front and rear), plug and play 4 channel signal input from the radio, accessory power, and remote output expansion harness for external amplifiers.
Note: It is important to add details of your bike in the order notes such as any factory amplifiers or if your bike is an ultra model so that we can customize the wire harnesses for your specific bike. Feel free to give us a call for clarification. 1(888)311-0016
