![]() ![]() ![]() Nor they will show the impact of different quality cross-over components. However. They will not tell us anything about speakers ability to resolve micro-details, the level of transparency, picture dimensionality and specific sonic signature. ![]() Without this clean bill of health all further subjective discussions are meaningless and pointless. Sensitivity graphs combined with a real speaker impedance reveals how easy particulate speaker will be to drive for an amp and etc. Box simulations and in-room far-field measurements will give us a good feel of bass extension. #Super sonic space pioneer driversLarge cancellations, sharp distortion peaks and funky CSD graph will instantly give away serious flaws with drivers and filters. We can easily see energy distribution in certain areas and have a good clue about tonal balance. When it comes to speakers – it’s a very efficient tool to get the basic stuff right. ![]() There is so much more to good sound reproduction and it’s way more subjective then any graph can tell us. They don’t tell us anything about how good or bad particular peace of gear will sound, unless it’s seriously flawed. I see people to often emphasizing on numbers and graphs and I strongly advice against this over-interpretation. Measurements are just that – measurements. Anyway, it was about time to unpack my measuring mic and look at what was going on. Capable of causing uncontrolled headaches? Could be the case. This made me laugh quite hard actually and I kid you not, these were his exact words.Īnd sure enough, after hooking them up for the first time and listening for a couple of minutes I could tell that something was seriously wrong here. Headaches – after listening to these speakers for a prolonged period of time.But wait, what’s that ? Oh look, it’s a hole ! Crackling sounds – bass units were main suspects but it was hard to pin point exactly as you needed higher SPL’s to reproduce the effect.I’m sure something similar happened here. And then you can have a beer or two with him and say look, remember when you were six and beat the crap out of that pioneer mid-range of mine? And have a good laugh right there. Basically it’s more then enough to raise a kid. Trashed mid driver – 25 years is a lot of time.Round plate and water marks were visible on all sides. Cosmetics – remember ladies and gents, speakers are not meant to be used as flower tables.Sorry, I didn’t made any hi-res before pictures, but main complains were: It was a nice score considering price paid, but sure enough they had seen better days. With all the buzz and controversy on “HPM sound” that surrounded these speakers all these years, I couldn’t say no to a friend of mine who brought me this particular pair for restoration. #Super sonic space pioneer driverJBL influence can be felt throughout all aspects of this speaker and I will look into driver similarities and crossover performance a little bit later. I would have a hard time naming any other mass produced speaker that came with 50mm face-plate. In contrast to other “paper” boxed Japanese speakers of that era it’s quite remarkable craftsmanship at a mass production scale. Beyond any doubt these are quality build speakers and you feel it right away, at whooping 26.7kg of weight your back is first to notice this. ![]()
