Big bass that's easy to replace

Soft Part System Boston's G5 subs combine high performance and outstanding sound quality in a woofer with some unique features. Bass competitors, check out Boston's pioneering Soft Part System (SPS™) — it lets you swap out the defective parts of a blown sub so your system is back in action a lot faster.


Extra protection, cool technology

SureSet terminals

The SureSet™ terminals come equipped with two fuses to help protect the voice coil during momentary overdrive, and allow you to change the woofer out quickly in case a fuse is blown. Also, G5 subs are compatible with Boston GTR TunableRadiators™ — a cool technology that can significantly boost the sound output of your G5 sub with no extra power or space required.


Advanced materials and engineering

But most importantly, the G510-4 10" subwoofer will really pound out the bass. The woofer's thick foam surround allows three inches of cone excursion, so it'll move lots of air — that means lots of deep bass. Boston's innovative RadialVent® system uses that same woofer cone motion to expel hot air that can damage the sub. Combine that with heavy-duty internal parts, and this sub will hang tough when you turn up the volume.

This subwoofer is optimized for small, sealed enclosures but also works in larger ported enclosures. Whatever type of box you choose, you can count on the high-end audio performance of a Boston Acoustics speaker.

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Features

Chassis: The Boston Acoustics G5 series high-performance subwoofers are built upon a rigid cast aluminum chassis. It features the patented RadialVent cooling technology which directs airflow around the 2-3/4-inch voice coil for increased power handling.

Materials: The G510-4 woofer has a co-polymer woofer cone with a raised polypropylene dustcap and a large foam surround. The wrap-around gasket gives you a good seal whether you top-mount or bottom-mount the woofer.

SPS (Soft Part System): The woofer has a removable assembly which allows you to swap interchangeable parts to make a different configuration, or service the woofer in the field. A 2.5mm hex key is included for disassembly. Note: The replacement single voice coil SPS assembly for this woofer is SPS-G5104 (item # 065SPSG510). You can also use the SPS-G51044 assembly (item # 065SPSG514) to change the woofer into a dual voice coil configuration.

SureSet: The speaker terminals are equipped with two 7.5-amp ATC fuses providing voice coil protection under transient conditions such as accidental momentary overdrive. Use of the standard automotive style fuses allows you to quickly service the woofer in case a fuse is blown during usage. Note: The fuses do not protect against voice-coil failure resulting from long term high power abuse.

Terminals: The woofer has rugged spring post terminals that accept up to 8-gauge bare wire or pin connectors.

Long Excursion: The woofer has a 3-inch peak-to-peak excursion for accurate deep bass output from a small sealed enclosure.

GTR TunableRadiators: The G510-4 is compatible with the Boston Acoustic GTR TunableRadiator (item # 065GTR10). These passive radiators, when mounted in an enclosure with the G5 woofer, can produce increased bass output without added enclosure volume. Note: The manual provides several enclosure shape examples for mounting a G5 woofer with a GTR TunableRadiator.

Enclosure Recommendations

Sealed Enclosure: The G510-4 woofer is optimized for use in a small sealed enclosure with a 0.5 cu. ft. internal volume.

Ported Enclosure: The woofer can also be used in a 1.3 cu. ft. ported enclosure with a 3" diameter, 11" long port.

Boston Acoustics G510-4

Written By fire120ball, Cali on Friday, September 11, 2009

This sub hits. period, sounds fantastic i found that when i was looking for a sub i wanted it to hit when i wanted it to, to really shake, but at other times i just wanted it to sound crisp, and clean not messy. This sub blew my expectations i have two in a divided/ported box and it hits when the bass is up and sounds clean when i just want good nice quality even sounds

sweet

Crutchfield Customer Review (What's this?)

I bought these to replace a single JL audio 10w7. The w7 was a excellent sounding speaker, but couldnt put out the output I wanted. Musically they sound up to par with the 10w7. But in the recomended ported box i have all the dynamic range i want. From Country to rock to rap, these flat out perform. I am powering them with 500 watts RMS to each. They seem to have a deeper and more authoritative punch then the w7. My rear vew mirror wont stay in position now unless i turn the bass knob WAAAY down because of that super deep powerful thump.The box for the G5's is tuned to 30 hz were as the box for the w7 was tuned to 38 hz. So that may account for the deeper extension. These are very pleasing at low leveles as well at high. They play very clean at the extream limits indicating that they are well matched at my current power levels. Needless to say i am very pleased with the purchase and recomend the ported 1.2 cu. ft box per woofer tuned to 30 hz. This is the first time i have purchased a non JL audio woofer in 15 years and not regretted it. In size, heavyness and build quality this is an even match for for my w7. I also like how I can convert them to dual voice coil in the future or just plain old overhaul them if they get damaged. Two thumbs up from me!

Best Subs I've Ever Owned

Written By Nick, Atlanta, GA on Monday, November 24, 2008

I put two of these in my wife's car and I am immediately jealous! One would have been plenty. They get loud and are amazingly clean. Each sub weighs 35-40 lbs/piece so you know it is gonna be loud, forceful bass, even in a small, sealed box. I own a JL Audio W3 12" sub and my wife use to have two Polk Audio MOMO 10" subs. Both are great subs also but are nothing compared to these Boston G510's.

If you are looking to build your dream car audio system and don't want to spend more than $400-$800/sub then buy one or two of these. You'll need to build or have a box built according to Boston's specs (0.50 cubic feet/sub) because it's almost impossible to find one already built.

This sub bumps period. I've got it in a 1/2 cubic foot enclosure with the GTR and w/ 200rms. It is by far the most bass for the least amount of volume. Highly recommended.
