![]() ![]() If there is a pretty clear blackened ring around ONE end of the coil, where it is blackened etc, then I would tend to suspect DC that pushed the coil out of the magnet "gap" on that side. If there is a blackened ring around both ends of the coil, it likely got a lot of lows, and was over-powered. If the coil is over-heated or burned-looking, possibly has shed some wires that are now loose, it was probably over-powered. Now, look at the voice coil, the coil of wire that was sticking into the magnet. Snip the two wires and lift out the cone (if it will come out, it may be stuck in the magnet). Cut around the outside of the cone, and also cut around the threated cloth "spider" that is cemented to the front of the magnet. ![]() If you still have one of the dead speakers (the actual driver) you might look at it. In a gig situation, you'd not notice anything until the speakers fail.Īs I recall, some Hartke amps had an odd protection scheme that could potentially produce DC if it was not working right. That leaves part of the coil un-cooled allowing it to overheat. That would be within say 2x the speaker rating, maybe 3x.ĭC certainly can be an issue for speakers, as it pushes the voice coil out of the magnet gap. "If the head is rated anywhere within reason of the speaker power rating, there should be no problem. Here's some good info from Jerrold Tiers (ex-Ampeg engineer) to help you diagnose what went wrong: Will the resale on the Backline even justify that cost? Dubious, methinks. The speakers in the Backline are unlikely to be as good as even Eminence Alpha 10s (their cheapest 10" woofer) which cost about £25 each from Blue Aran. It wasn't really an issue of too much power for your cab so much as an issue of not enough SPL (power x speaker sensitivity) capability from your rig resulting in pushing it too hard - like driving a car permanently in the red. As you were using a single 2x10" with a 200W head for what looks like a fairly rocking covers gig, both problems probably happened. That would be unlikely to blow the speakers unless you were constantly clipping the amp (causing increased average power and thus thermal damage) or expecting too much bottom from a small cab (causing overexcursion and thus mechanical damage). The cab is an 8 ohm cab rated at 160w and I think, using it with my Hartke on it's own, I was putting more like 200w into it! Looking forward to the 15th - how's it going with the Sub 5? Anyway, it sounded brilliant - even made me like my Hartke head again? The combination of the DJ5, bit of compression and that old 1x15 was just great.So, apart from changing the Hartke for a GK 700, I might just have found a sound I really like that is also fairly compact for carrying around. It's the cheap rig I used to get started with after I decided to start playing again after my 12 year sabbatical.Īnyway, the cabinet is tatty as anything but inside is a really good 1x15 driver with the aluminum center cone (is that a black widow?). No problem - family comes first! Good luck with Plan C.exciting stuff.įunny enough, because I had this problem, for a gig on Sunday night and instead of my GK Backline 1x15, I decided to take out my old hand-made 1x15, which I bought along with an old Peavey Mk IV amp for £100 about 18 months ago from someone on Bassworld. If you do not get it sorted my sound guy certainly used to have a good reasonably priced contact for recones & I could check with him for you Of course none of that is of any use in your speaker problem. I nearly came over myself on Saturday, but #1 son was home for the first time in 7 weeks so family duties & a curry took over.īTW Plan C may come to fruition over the weekend Excelent tone for whatever you play! Seriously needs a quality speaker upgrade to handle deep tones and lower registers, but that would defeat its budget price.Sorry to hear of your problems Nik. It might be ok for a jazz band or recording, but nothing with any volume. Don't think you'll be getting anything else. Good amp, quality hardware and controls, poor speaker quality though. Also, my particular amp shuts down while I,m playing! Sometimes I can't even get the amp to turn on! The amp is only a year old. Speaker and cabinet cannot handle the lower registers of a 5 string well at all, and even though its 100 watts it could never sit beside a drum kit and try to play rock music. Great looks, easy to transport, loud enough to hear with my music turned up, total control over an awesome sound. Looking for a practice amp, I went to my local Guitar Center and foud the Backline 112 to sound great and was loud enough for personal practice. I'm currently looking for a band needing a bass player. I've owned quite a bit of gear over the years and have played in 3 different bands. I'm 38, and started playing bass and guitar at 15 years old.
