Dynaudio Subwoofer

It is extremely well-suited for that extra punch to the bottom end in setups where space is limited. The BM9S delivers a clear, crisp and surprisingly powerful punch, when you take its almost diminutive size into account.
The BM9S will complement stereo and multichannel monitoring equally well and, when daisy-chaining of subwoofers is needed, it sports a low level LFE input/output.
For significant control and enhancement of the general performance, the BM9S is a closed cabinet type. This creates an internal pressure by which the woofer gains a considerable amount of precision when it comes to the reproduction of low frequency signals. This precision is easily audible and it augments the feeling of reality that the listener experiences.
The BM9S is very suitable for the following production environments:
Post Production
Music Recording and Mixing
Film Editing (smaller rooms)
DVD authoring and Mastering
Multichannel Production (Audio or Audio for pictures)
Broadcast
Edit suites
OB vans
The BM9S is designed according to the strict, BM series specifications. With a 10 inch woofer, 200 Watts of power and virtually minute dimensions, this sub is tailor-made to take care of even the most comprehensive challenges where space is scarce. Being every bit as versatile as the rest of the BM series, the BM9S is a very competent partner for smaller stereo and multichannel setups, giving a very powerful system for even the most demanding users across the globe.
The Auto On/Off function provides a minimized idle energy usage by shutting off after minutes of no input signal. The auto sensing circuit also enables BM9S to automatically come to life when input signal is detected.
The satellite filters that this sub sports provide high-pass filtering of the monitor source signal, allowing 60Hz or 80Hz corner frequencies. This is a huge advantage for the monitor performance, as the satellites do not need to deal with power-consuming lower frequencies. This leaves all the satellite power to greatly accelerate performance and precision.

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: Starting at 4% of the current new selling price to double the warranty from 1 year to 2 years. Starting at 4% for each additional year.
- USED products: Starting at 4% of the current new selling price to increase the warranty from 3 months to 1 year. Starting at 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.
