Posted January 4, 201114 yr Does anyone know any information on the Boston Acoustics SPG555? Is it a good performing woofer or just another mainstream average sub?http://www.bostonacoustics.com/SPG555-P567.aspx555 cm2 of surface area3¾ inches of peak-to-peak excursion3½ voice-coilRadialvent® cooling technologyOnly 26 Lbs! Thanks to Neodymium Lightweight designRVC™ (Removable Voice Coil) allows coil to be exchanged without removing the woofer from the enclosureSPS™ (Soft Part System) removable assembly enables field repair of the cone/surround/spider assemblyCan be field-stripped and custom painted, powder-coated, or platedWork in multiple enclosures, both sealed and portedIntegral sealing gaskets simplify both standard and inverted mountingAvailable in 4-ohm and 2-ohm versions Reason I ask is because my brother is thinking about buying one.Thanks guys.On a side note, removable voice coil seems pretty user friendly
January 4, 201114 yr Link is bad dude. i dont know anything about the sub and never heard it. i can see that the oval design is just to increase surface area, like the kicker square subs. i assume it probably has the same problems, given that the cone is not circular, there is added stress to the cone which can cause failure. i dont know if this sub has a problem with this.. regardless it still is just a gimmick. the replaceable coil is just another gimmick imo. buy a sub from Fi or other company and get a recone if it fails..
January 4, 201114 yr Author Link works for me?Thanks for the thoughts though, much appreciated! I'll let him know.
January 4, 201114 yr those SPL lane in field repair features are just plain stupid since the tracetrack design makes it not usable in the lanes ,racetrack designs do not suffer the same problems square woofers do , at least to my knowledge .they sound good , but no better than to be expected ,a nice feature is the passive radiator that is available , something you don't see very often anymore .in that regard , Fi wouldnt mind making a passive eighter though Edited January 4, 201114 yr by BASSmaster
January 4, 201114 yr Some local car audio company had that in a ported enclosure, he said it was the "true W7 killer".It sounded okay, better then the other equipment he had in all pre-fab boxes, even the 15's.But the box looked rather more designed for the BA and the others were all too small for them
January 4, 201114 yr I have never personally owned one so I don't know how they perform long term. I have heard the SPG555PS package in a SUV and it did pretty well, can't remember what amp was powering it. I have owned Boston Acoustic products before (comps, amps, subs-g2 and g3) and I have always been impressed. I would not touch that sub for $650, maybe you can get it for a better price?
January 12, 201114 yr has a brutal low end not to great on higher notes and had a few problems.....blew once then spider detached from frame but i liked the way it sounded good sub for 300
January 17, 201114 yr Boston Acoustics is a quality car audio company and their equipment can definitely be trusted. However, for 650-700 dollars I would not buy one of their products. Im sure, with 700 dollars, you could purchase a driver that gets louder and sounds better than this particular driver.
January 18, 201114 yr 700 bucks for a driver with no T/S specs? No thanks...2nd page of the manual lists T/S parameters: http://www.bostonaco...s/SPG555Man.pdf
January 18, 201114 yr its only worth 350 tops but if u can get it in ported enclosure ba makes for it this thing will wang had it in trunk of 2005 mustang off a t1500-1bd it was the 2 ohm version of the spg just make sure you dont clip signal at all or this sub will blow i would actually under power it burns coil if more than 1200 watts goes to it
