the how and why of bass in your BMW / Mini

Fully 1/3rd of all recorded music is below 80Hz (this is called bass!) Almost no interior component speaker can reproduce sound below 80Hz without high levels of distortion (some CAN reach to around 60Hz, but that's really the lower limit). The cheap drivers BMW and Mini use in their audio systems are no certainly no exception to this rule.

Why? High output bass production requires that a speaker physically moves a great deal of air relative to what's required for higher frequencies. This air movement is accomplished in either or both of the following two ways:

• High Excursion: Excursion refers to how far a speaker can move in or out from its resting state. The smaller the speaker, the larger the amount of excursion required to produce bass output -- and vice versa. However, a small driver with high excursion is far less efficient than a larger driver with lower excursion (require TONS of power from the amplifier) and is very impractical in a car audio situation due to the space required in front of such a driver to accomodate the movement. (It's also difficult to design a very high excursion driver that remains accurate at the limits of its movement).
  
  
• Large Cone Surface: As the cone surface area of a speaker increases, the more air the driver can move -- and the more efficient a driver becomes relative to a speaker with smaller cone surface area. However, the additional mass of such a driver requires more power and a more stout motor structure (the components that control the speakers) to keep the driver controlled and accurate.

Both solutions do require substantial power output from the amplifier driving them, but power can be expensive. For cost savings reasons, manufacturers will produce a larger coned driver out of lightweight material (i.e. paper) to minimize power requirements. Unfortunately, the resulting lightweight subwoofer is flimsy, and when combined with low power yields muddy, fuzzy bass at moderate volumes and distortion at high volumes. This is PRECISELY the case in BMW and Mini premium sound systems.

And if you don't have the premium system, because your stock amp and speakers (and even high quality component speakers and an aftermarket amp) are small in size, share the same lightweight construction, and are low in power, you'll get the same fuzzy bass, just less of it.

And so, an effective, high power subwoofer solution is needed. But with the BSW f110, it doesn't have to come with sacrifices.

absolutely everything you need is included!

The BSW f110 subwoofer system is a 100% complete kit. All you need is basic tools!

BSW f110 Subwoofer Enclosure	BSW by Alumapro 10" Alusonic MX Aluminum Cone Subwoofer
Rockford Fosgate P200-2 Amplifier (230W @ 4 Ohms)	All required installation hardware, wiring, and accessories
Detailed step-by-step instructions with photos	Performance Guaranteed Unconditionally guaranteed to exceed all your expectations or your money back.

Is this EVERYTHING I need?

Yes, we include absolutely every single component you need! There is absolutely nothing else you need to purchase outside of the BSW f110 Subwoofer System to install and enjoy our system.

Can I install the f110 Subwoofer System in my BMW myself?

Yes, you can! We ship every BSW f110 Subwoofer System with extremely detailed installation instructions with photos and provide telephone support for the process as well. Because it's a simple installation (you're basically just tapping one audio signal and getting power from the battery - that's it!) with only the most basic of skills required, you can probably do it. However, if you feel unsure, we always recommend professional installation. Fortunately, because the installation instructions are so good and everything you need is included, if you don't feel comfortable with the installation process, any decent car audio shop can perform the installation for you without any difficulty whatsoever - probably for about $150 or less.

Will this work with my Standard or Harman-Kardon equipped BMW or Mini? Will it make a big difference?

Yes, absolutely! In your audio system, even the Harman-Kardon systems, bass response is terrible; output may be there, but accuracy just isn't. Because our f110 Subwoofer System provides as little or as much additional bass response as you want, you'll see a VERY nice improvement in sound quality and low-end frequency response in your BMW or Mini, regardless of whether you have the most basic audio system or the nicest.

My trunk is completely sealed. Will I really be able to hear the bass in the cabin?

Yes, definitely. Because we specialize in BMW's, we understand that the trunk areas are very frequently 100% sealed from the interior of the car, and as a result, this important consideration was taken in mind during every step of the design process. This means that our f110 Subwoofer Systems are high-output and will absolutely produce enough output (volume) to really hear, feel, and truly enjoy!

What components are included in your f110 Subwoofer System?

Click the "What's Included" tab above for an itemized list of the components used in this subwoofer system.

Why don't you use more common name brands like JL, Infinity, etc.?

We haven't used more commonly known "name brand" components in our subwoofer systems because we wanted to provide the absolute best system possible for the most reasonable price to our customers. Frankly, much of what you pay for when you go "name brand" is just that - the name. Our testing revealed that the components from the smaller companies that we're using in our subwoofer systems provide a MUCH better value because you aren't paying for a name. You're paying for the quality of the components and engineering, and as such, for the same amount of money you get so much more performance, output, and clarity. So, in short, we use the components we've selected because they give you, the customer, the very best "bang for the buck."

Do I need to replace my factory amplifier or head unit?

No, you don't. We include a new amplifier to power the subwoofer included in the f110 Subwoofer System. If you have your factory head unit, we also include all the necessary wiring you need to integrate this system with your factory head unit. This system also works with all aftermarket head units as well!

Will the f110 Subwoofer System be visible from within the car or require any permanent modifications?

No, our f110 Subwoofer System is completely invisible within the cabin. Only you and your fellow listeners will know that you've upgraded your stereo since your car will maintain a 100% factory appearance within the vehicle. And in the trunk or cargo area, because the BSW f110 Subwoofer Enclosure used has a stealth, clean look, it's hard to tell there's a sub system in your trunk, either!

No permanent modifications are required.

Does the BSW f110 Subwoofer System come with a warranty?

Yes, it sure does! The warranty is 1 year, parts only, on all components of the f110 Subwoofer System. If you ever have any issues, we're just a phone call away. Please note that this warranty DOES NOT cover subwoofers blown due to excessive volumes or abuse.

Author: Hung Tran, VA, USA I got this package with the premium woofer and I love it. Coby was very very helpful. Great customer service guys ... Keep it up !!!!
Author: R. & J. Goldstein Jason , My son and I just wanted to thank you for your help and the subwoofer system is incredible. What a difference it makes!
Author: HeavyD I had the Stage 1 and 10 inch subwoofer package installed last week. So after a weekend listening to it, here is my thought about the products. Overall I am happy with the result. My Xs audio system comes alive. I particularly like the sub. Its deep, accurate and powerful. The speakers are clear especially the tweeters. All of my friends listen to it and said it sounds awesome. I feel a 10\ sub is definitely enough for a X5 but its just my personal opinion. I listen mostly to Trance and Hip-hop. Now even though the speakers and subs are good on their own, I do feel there there is a gap between them. I believe the reason is that the sub is powered by an ED amps while the speakers are powered by the factory amp. As good as it sounds right now, I feel I can get more details out of those MB Quartz by adding an aftermarket amp. And thats what I am going to do.
Author: rob just install this unit yesterday and it is probably one of the easiest installs ive ever done. this sub absolutely pounds. i used to run a 12\ kicker solobaric in my old car and this 10 hits harder and sounds better than that 12 ever could.
