BM Series – Subsonic Solutions For Today’s Demanding Environments
When devising subsonic solutions for modern vehicles one of the biggest challenges faced is in-car real estate, or lack thereof. Everybody wants a decent amount of subbass but sadly many just cannot afford to sacrifice titanic amounts of space. This is where the superb BM subwoofers from Stereo Integrity come to the rescue. Constantly improved and enhanced to suit modern cars and featuring extremely powerful motor structures; the BM subwoofers present an extremely thin design that’re easily able to fit behind the seats of just about everything ranging from sedans and wagons right through to the most austere tradie truck! If space is your problem; the BM series subwoofers are your solution.

Design Ideologies
World renowned and highly praised; the BM series shallow subwoofers are back! Stereo Integrity’s latest BM-11 puts a refreshing spin on the high-performance shallow subwoofer concept. The latest version is tooled up with a new basket, a new Carbon fiber flat diaphragm and an all-new low profile S-surround to maximize ease of installation. The result is an 11″ subwoofer with only a 3″ / 76.2 mm mounting depth while still having 14 mm one-way Xmax.

A Motor Most Serious
Getting proper bass out of a shallow subwoofer is challenging, but the BM range possesses the right recipe with its dual-gap 10 piece neodymium column shallow design. The multi-piece neodymium column motor drives an eight layer copper voice coil through two magnetic gaps with a brass shorting ring directly in the middle to lower and linearize inductance for quick bass response. Linear piston movement of 14 mm one-way makes sure your bass is distortion-free during the most demanding program material.

Superior Suspension
Engineers optimised the custom tooled S surround to have the highest surface area possible while still allowing enough mechanical travel past the linear limits of the motor.

Beauty Atop
Upon the front side of the driver is a beautiful gloss carbon fiber flat piston. A careful balance of motor strength and moving mass allows our BM-11 subwoofer to play a broader bandwidth than any other shallow subwoofer on the market. Mounting depth is only 3″ / 76.2 mm and physical weight is light at only 7.3 kg.

Design Features
The rich heritage of this astute and masterful designer, together with its ever-increasing technical acumen; is conducive to these components featuring a vast array of impressive design ideologies and latest technological advancements. Some of these include:
– Flat carbon fiber sandwich diaphragm for superior strength and light weight.
– Custom tooled cast aluminum frame. Aerodynamically minimal and magnetically inert.
– Custom engineered S surround with integrated gasket.
– 3″ / 76.2 mm diameter eight-layer solid copper voice coil.
– Ten piece neodymium column motor structure.
– XBL^2 topology for reduced inductance and high Xmax.
– 14 mm one-way linear excursion.
– 500 Watts continuous power handling.
– Dual voice coil configuration.
– Small sealed enclosure size of 0.30 to 0.60 foot cubed or infinite baffle.
– Shallow mounting depth of 3″ / 76.2 mm.

A Note About The Pricing
We’re sometimes asked why Australian prices are higher than those listed overseas. Allow us to explain how we stores arrive at the price for these components.
– You first take the US price and run it through an exchange website to covert it to Australian dollars.
– You then have to add ten percent for GST tax. The Australian government stipulates that this tax is compulsory, therefore it must be added.
– You then add the cost of air-freighting to Australia. Now products can be shipped via surface freight but the wait can sometimes drag out many months. For a weighty product like this the cost is quite a few hundred.

Put succinctly; between our dollar not being so strong against the US dollar, European euro or British pound, in addition to us being far away geographically; this is conducive to products costing more here in Australia.
