Boston Acoustics G215-4

I bought this sub off here and it shipped fast (as usual) great deal. I found that it is really easy to blow the fuses though. I have g1's and don't blow fuses on those. But if you have it wired to under 200 it still really pounds. Good in a large 3 cubic foot ported box .

I did 3 Boston g2 15 s in my dodge RAM. Excellent mix of spl and sq . Been installing for 20 years now. I am sad to see Boston leave the car audio market . I've been a fan since beginning. I guess plastic parts and shinny prices are more important that good speakers :(

Ok, these are simple, require very little power, high sound quality I cannot think why you would not buy this sub. Boston knowledge behind sound.

I decided to purchase a pair of these subs due to the fact that while on clearance, they were one of the most inexpensive 15" subwoofers I recall coming across from a reputable company. I had read a review on a forum that was very negative that almost detoured me from purchasing. Having used several Boston subs, I found this surprising. The claim was that the woofer did not perform well in a 1.5 cu ft box.



Upon receiving the woofers, I did in fact install them in a 1.5 cu ft / sealed sub enclosure. The review was accurate. The subs lacked low end and needed a ton of power to get loud. The subs also do require a break in period. They got better after about 4 hours of play, but still pretty lackluster all in all. I was not sure that half a cubic foot per chamber would make much of a difference. Even looking at my enclosure design software, it showed little difference. Regardless I decided to build a new sealed box anyways.



The subs are running off a Rockford Power series 1000.1bdcp. In a 2 cu ft enclosure, these subs get impressively loud and sound exceptional. Sound quality (my own subjective definition) at the $300 price point is well above average. The competition gets pretty elite at 300 bucks per sub. When you factor in the output available with very moderate power levels, the sub sets itself apart from almost any other driver at that price point.. They are also very efficient in the 2 cu ft / chamber sealed box and I would say a 600 watt amp is more than adequate. I dropped the low end output on my Pioneer DEX-P99 to -9db per sub from where they were at in the 1.5 cu ft sealed box.

The boston G215 is tied for 1st with the JBL w10GTI in my opinion. The JBL is the best sound quality sub I have heard. The JBL is not very efficient and requires a ton of power to get the volume I desire. The Bostons fulfill that thirst for output while the sacrifice in sound quality is there, its well worth the trade for my setup.



The only negatives are that the speaker terminals seem like they are upside down and can be tight to fit your fingers in to press depending on the length of speaker wire your dealing with. The other is that these subs want 2 cu. ft or more sealed. Many 15's on the market can work in less space, these lose a lot of performance from even a slightly smaller enclosure. The included screws have a very small head and strip easily. For these reasons 3 stars on ease of use.



If you have the room for a 4 cu ft enclosure and want a pair of great sound quality subs that can bounce large items off your roof at will, these should put a smile on your face.

Im "Anal" about my sound. When it comes to Trance, Slope Hiphop, Post-Hardcore Rock (repetitive double kicks) You need a responsive woofer. Most run over towards 10's for response but i like the Deep thump that comes from a 15" woofer cone. The G2s are made with light weight materials, perfect motor for moving air, and built phenominal. I couldve spent 2-3 hundred dollars on a woofer from some one else but why do that when Boston makes car audio? They kick hard, and thump out some serious spl from sealed enclosures. I'll probably buy another, and keep this for life..
