Need Opinions on a Sunfire True Subwoofer MK II

Post by EndersShadow » Tue Jul 03, 2012 12:13 pm

Whats this sub go for used in decent, and what is the consensus on it? Does it have any inherent problems I need to be aware of? I read a couple places about the amps going bad and whatnot, but I tend to trust the input here more than that.

I currently am rocking a Polk PSW125 and know I have lots of room for improvement.

My options are get this sub or look into getting the M1.0t I purchase refurbished, or try and score another M1.0t for my center channel as wel. I dont think the M1.0t that I just got needs refurbing just yet given the pictures I got from the seller, but I figured I might as well just do it and get it out of the way, unless I pick up this sub.

So I am hoping folks here might be able to help me make up my mind.

Look forward to your thoughts....

Sunfire subs were ahead of their time & fantastic for tiny package & big sound, but because of those facts, they shake themselves to pieces. One of the BEST sub values around are the ones offered by Epik:

They typically sell for around $450-$650 shipped on eBay. The plates do require service a lot of times, too much internal force breaks the caps lose which causes buzzing and a host of other problems. Refurb on the plates cost $270 at Rita's. As far as performance, you better make sure shits nailed down tight!! They will literally walk themselves across the floor in a jack-hammer type motion when pushed to the max. Not the greatest though from about 50hz and up but below that down to 20hz look out!!

This one is quite a bit less than that, so its good to know its a bargain. The question then becomes is that because there ARE issues with it, or because the seller doesn't know what he has, etc. I am waiting to hear back from him to see if I could demo it before purchasing as thats an almost guaranteed dealbreaker.

Yeah it would be on a Auralex subdude HD and honestly wouldn't be pushed to the max too much. Since they will be paired with my Polk LSi setup which is currently all set at 60 hz I think it would pair well with them. The only problem I see is that my receiver wont let me set the crossover for the sub lower than 80 I think, but they will have the Polks to help out above 60 hz.

I am running Polk LSi 15's and a LSiC center. The 15's are going to be run off a M1.0t I just bought and the LSiC is off the Carver 705x I currently own.

The Truesub has a built in crossover and should work great if paired with a set of full range (or close to) front mains. One option that has not been mentioned is either build your own sub, or what I like to do is find a sub with a bad plate for cheap then add your own. I'm running a Velodyne FSR-15 with a new Bash 300 plate. The origianl plate was 250 watts so the new plate is perfect, I actually think it hits harder now then it ever did before! :D :D

Yeah I know that's a cheaper option but I found this one for under 200. It's hard to find something better than my PSW125 that's DIY and under that.

I like the Dayton 18" and could technically use a channel off my 705x to drive it. I really like the sub I linked to above and will get one eventually. I think for now I will probably pass on it and either pic up another M1.0t or get mine refurbished.

The Sunfire True series subs can easily be repaired and replacement drivers are still around. I like them and own several. However, The JL Fathom subs are bad ass. F U James.

Had one, liked it all right, but wound up selling it to a buddy and have a pair of HsuTN1220's instead (stereo subs, FTW!). I liked it better after *hard-mounting it to a 12x12x2" chunk of black granite (32lbs of deadweight) with 5/8" spiked feet. If unmounted, it moves around, and not just a little bit. Even mounted to a stone block with a wider footprint and spikes, it still fucking moves under certain conditions. Movement of a sub = robbed output, since instead of imparting movement to the air with the drivers it's shaking it's heavy ass back and forth, wasting gobs of power in the process and all you get for your troubles is muddier bass since it starts eating into phase alignment. Honestly it would probably perform best mounted to something like my granite base, with that heavy driver facing up or down, since that is the only axis it's mass can travel without dramatically affecting it's balance. If it electronically hums, try tightening the nut on the volume knob with a socket wrench before panicking. It's grounded to the plate and shakes itself loose easily. That and what everyone else said....

-p

*drilling four 1/4" through-holes and four blind-holes, a total of 12 linear inches, through solid granite was an adventure all in itself... stainless hex bolts into T-nuts in the sub, spiked feet were epoxy potted into their holes... looks killer though

I purchased a Sunfire True Subwoofer Mk II brand new in 1997 and the only reason I'm not using it currently is because I 'upgraded' to a Sunfire True Subwoofer TS-EQ10. Though I was always happy with the Mk II, after purchasing and installing the TS-EQ10 I was blown away by the difference the built-in equalizer had on the sound quality in my listening room! The same results could probably have been achieved with the Mk II using external components and/or room treatments.

Other than a bad ground on the plate of the Mk II I never had any problems with it. Mk II units typically go for around $500-$600, in my experience.
