While subsonic frequencies are heavily implemented in some musical genres, all studios benefit from the use of a sub to monitor this low frequency content. With the prevalent use of home theater systems, as well as commercial systems in clubs and cinemas - production studios require the capability to identify and correct problems such as unwanted low frequency components, exterior noise, microphone rumble and vibrations. The increase of home and project mastering means many potentially great pieces of music are being poorly represented when played back on a larger system. When dealing with subsonic frequencies if they cannot be heard accurately they cannot be mixed accurately.
Having an incredibly capable subwoofer is critical when it is combined with powerful near-field monitors, such as the Expos or a VXT8 driven to high sound pressure levels. In a stereo configuration the subwoofer will have to produce the bass that would normally be generated by the monitors -- that alone can exceed the headroom of an ordinary sub. In a surround sound configuration the subwoofer has to reproduce all of the low-frequency information from five or more channels as well as the demanding bass content of the LFE channel. These challenging applications can place demands far exceeding the capabilities of normal low frequency drivers and power amplifiers. This is where the performance of the KRK12sHO shines.

Protect your investment with the Long & McQuade Performance Warranty
A warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.
Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.
How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?
- Performance Guarantee: Normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage. Band and Orchestral Performance Warranty does not include replacing pads or cleaning for woodwind instruments, unless deemed necessary by our repair staff. Ultrasonic cleaning for brass instruments will be provided if deemed necessary by our repair staff, but is not routinely offered under the Performance Warranty.
- Product Replacement: If your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.
- No Lemon Policy: Your product will be replaced should the same problem occur multiple times.
- Convenient: Easy drop off and pick up of the product at any Long & McQuade location.
- Guitar Setup: Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.
- Loaners Available: A loaner product may be given while the product is being repaired.
- Power Surge Protection: Your product is covered even if damaged from a power surge.
- Accessory Coverage: Any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.
- Commercial Use Coverage: Music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.
Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty. Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Cosmetic Damage, Accidental Damage, or problems caused by Humidity or Temperature Issues are not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.
Purchasing additional years of coverage
Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.
If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:
- NEW products: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
- USED products: 4% of the current new selling price to increase the warranty from 3 months to 1 year. 4% for each additional year.
- GUITARS: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.
- BAND and ORCHESTRAL instruments: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
