Product Details

Eminence Beta-6A 6-1/2" High Power Midbass Midrange Woofer Speaker

The Beta-6A 6-1/2" midbass/midrange from Eminence is the evolution of the vaunted Alpha-6 driver series. With the Beta-6A, Eminence has increased the voice coil from 1.5" to 2" for increased power handling, while a strong magnet and motor system keeps the sensitivity high. 

In addition to a larger diameter voice coil, Xmax has been increased to 4.5 mm and allows for lower usable frequency response. Additionally, a vented pole piece allows heat to escape for reduced power compression. The paper cone and dust cap have been treated for water-resistance, which is perfect for when the Beta-6A is used outdoors for live sound and in high SPL car audio systems.

Eminence designed the Beta-6A to work well in small sealed or vented enclosures, and in infinite baffles too. See the Manuals/Resources section for Eminence's cabinet design recommendations.

Eminence Beta-6A 6-1/2" High Power Midbass Midrange Woofer Speaker
Eminence Beta-6A 6-1/2" High Power Midbass Midrange Woofer Speaker is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Beta 6-A - IMPRESSIVE!I bought 2 of these to put into 15"Hx9W"x6D" ported boxes I built out of 3/4" mdf and built into the walls for L/R Fronts for my HTS. I paired with the APT-80 Super Tweeter and I couldn't be happier. Using WIN-ISD, response shows flat line from 85Hz up which is great since I'm crossing them to my sub-woofer at 90Hz. These speakers are very efficient and clean. Although they are not broken in just yet, I would definitely recommend them for anyone thinking of using them the way I have. I play in a band and have used other Eminence drivers in the past for pro-sound applications and have come to really love this company and their products.

Rated 5 out of 5 by from Great compact mid/bass wooferI don't usually write reviews, but I couldn't find any reviews for this woofer before buying it, and I feel it deserves one.In short, this woofer packs a surprising amount of punch for a 6.5" speaker, while still maintaining clear mids. My particular application is in my car doors. I paired it with Dayton Audio PT2C-8 Planar Tweeters (awesome tweeters, btw) to provide hifi and high SPL audio in my car. I built 2nd-order crossovers at 3,500 Hz. It's tricky getting enough power into an 8-ohm speaker using a car amp, but it turns out these don't need much. I estimate the max power being used at 55W RMS per speaker, and it easily gets to painful loudness levels before distorting.What's great about this speaker is that, regardless of the enclosure size, according to calculations based on the T/S parameters, the excursion limit will not be exceeded at its rated power at any frequency in its response range. Even below its response range, it is only barely exceeded at full power. This translates to avoiding distortion with heavy bass. You can drive these things hard, and they maintain clear mids. That's mainly why I chose these, since I needed them to get down to at least 100 Hz where the subwoofer will take over, without knowing the effective volume of the doors or even if they would act well as a sealed enclosure.The only cons are: The magnet on this thing is massive! I had to cut the opening in my car doors bigger to accommodate it. The magnet is almost as big in diameter as the required mounting hole. I consider this an expected trade-off, so no star docked; just keep this in mind. It would also be nice to have a 4-ohm version.So, in conclusion, I'd recommend these for any application where size is a constraint, and you need a speaker that can handle midrange and bass frequencies. If you only need midrange, I think it would be a waste of this speaker's low-end potential, and there are probably better options out there. But as far as a 6.5" mid/bass woofer goes, it's hard to beat!

Eminence Beta-6A 6-1/2" High Power Midbass Midrange Woofer Speaker

I play bass guitar - onstage I have difficulty hearing my notes clearly and a mic stand type monitor would be a perfect solution. I don't need great bass tone, just clarity of notes being played - would this spkr do the job - also alpha 6a?

Asked by: Quinny 2
This driver will work well for an application like that. I would recommend an enclosure volume of 0.3 cubic feet with a 2.5" diameter, 3" long port for a tuning frequency of 90 Hz. A high pass filter may be required above 80 Hz if you want this to handle full RMS power.

What is exact mounting depth of this speaker? Planning on using four of these in my truck doors with baffles, will speaker reach 100hz because it is not being using in an exact sealed enclosure.

Asked by: adam1
The mounting depth of this speaker is 2.7".

I am once again submitting a request:  I would appreciate specs for a correction filter which provides a smooth response for this driver.  I aim to employ the driver in a 2-way (with a tweeter), in a sealed enclosure, crossed over at 2.5kHz.

Asked by: Azymov
Unfortunately there is no such fixed filter for this type of thing. The frequency response of this driver is relatively smooth as is but will be affected by baffle step. This frequency will depend on the dimensions of the baffle, and the best way to create a filter will be to measure in the cabinet to see where the baffle step starts, and design a filter based on that.

Will these drivers fit into a 1997 acura integra, in the front low-freq speakers positions?

Asked by: randalfo
According to my reference the vehicle has 6-1/2" stock speakers, although the depth is limited to 2". These are 2.7" deep, so extensions may be required for the install.

What tweeter would work well with an Eminence Beta-6A 6-1/2" High Power Midbass Midrange Woofer Speaker?

This is going in a boat, in an open enviroment The speaker will be mounted on the side of the interior. The wall opens up right below the speaker so the isn't any enclosure. So my next question is should I enclose it? and how much air space does it need?Thanks to all
Asked by: hoser0354
Any super tweeter will be a good match to this mid-bass. It does not have to be in an enclosure although you will get slightly more upper bass in a small vented enclosure. 0.35 cubic feet with a 3" diameter, 3.5" long port will tune the enclosure to about 100 Hz. I would recommend a high pass filter at 80 Hz to prevent over excursion at high power levels.
