Showcasing the Best in the Mobile Enhancement Industry
We’re now into our fourth speaker in our series about understanding speaker quality. For this article, we will analyze the performance of an old-school premium speaker, the MB Quart PWE-160. If you were into car audio in the ’80s and ’90s, then the MB Quart brand was a name you’d know well. This brand was famous for its performance in car audio competitions. So let’s see how Read more
Pickup truck sales per year have more than tripled in the last three decades. With millions of these vehicles on the road, it’s no wonder that the popularity of shallow-mount subwoofers has increased dramatically. Hertz has recently introduced 10- and 12-inch shallow subwoofers in their top-of-the-line Mille series. These subwoofers are rated to handle 500 watts of power Read more
As you may know, the product development team at Sony has been busy over the last few years creating an entirely new line of premium car audio products. Their efforts have rewarded the industry with the amazing XAV-9500ES multimedia receiver, as well as six speaker solutions, three amplifiers and three subwoofer offerings. In this Test Drive Review, we’ll inspect and evaluate Read more
Expert installation technicians in the car audio industry are fortunate to have several options to simulate speaker and subwoofer response in different applications. Whether it’s modeling a bass reflex enclosure for a pair of 12-inch subwoofers or ensuring that an A-pillar speaker pod is large enough for a 4-inch midrange, computer simulations are crucial to delivering car Read more
Dual voice coil subwoofers exist to provide installers with three options to connect the driver to an amplifier. The coils can be wired in series or parallel to double or half the impedance of a single coil. Alternatively, each coil can be connected to separate amplifier channels to add power from non-bridgeable configurations. A question that often arises is, what happens if Read more
I purchased a pair of MTX 6.5-inch woofers around 1992 or 1993, and they were installed in my 1991 Mazda 323 hatchback as midbass and rear-fill drivers. Later, they migrated to a set of “home speakers” with an Audax tweeter, though I don’t think I spent much time listening to them after I finished building them. Unfortunately, those speaker enclosures were thrown out after they Read more
A short while back, we published an article headlined “What Does it Mean When a Subwoofer Claims to Work in a Small Enclosure?” One of our readers, Eric T., asked some great questions on our Facebook page, and we told him we’d be happy to answer them. The original article explained the physics of what happens when you try to stuff a subwoofer in an enclosure that’s too Read more
Who wouldn’t want to buy the loudest, most efficient speaker possible to upgrade their car audio system? A speaker that does a better job converting electrical energy into sound reduces the load on the vehicle’s electrical system, right? Well, efficiency is just a single parameter in the myriad values that describe how a speaker works. Let’s take a super-techy look at how Read more
A while back, we looked at how some car audio speakers and subwoofers change in performance after they’ve been broken in. We analyzed how the Thiele/Small parameters of a sample subwoofer changed after being played for many hours. What we didn’t clarify adequately in that article was whether or not speakers had to be broken in before use. Parts of a Speaker or Subwoofer Let’s Read more
For car audio enthusiasts who’ve invested time studying the Thiele/Small parameters of speakers and subwoofers, you’ll know there is a specification called Xmax. This variable, typically expressed in millimeters or inches, is intended to describe the one-way excursion capability of the driver. Put another way, it’s the distance the cone can move forward or rearward from its Read more
When it comes to correlating how the parameters of a speaker translate into music reproduction, well, the details are often somewhat sparse. One speaker characteristic that’s often overlooked when searching for new subwoofers or woofers is Q. This unitless number is a key component in describing how the suspension and motor work to control and damp cone oscillation at its Read more
