That should sort the neighbours out
 I am fortunate enough to have the luxury of a PA in a soundproof studio and a separate HI FI system in my house.

ultra-low distortion bass reproduction is over-rated. our ears are so bad at hearing bass that it is the higher order harmonics induced in the ear that we are really detecting and interpreting as the fundamental frequency. search for 'missing fundamental'. it's not perfect because the otolith organs do detect very low frequencies and are more sensitive than the cochlea. it is possible to completely replace the fundamental with second and third order harmonics at lower volume and the resulting perception is almost indistinguishable from the full volume fundamental - in this case the system is producing 100% distortion and it sounds okay.
all drivers will produce 3rd order harmonics as they approach xmax, if they can also be designed to produce significant 2nd order harmonic from asymetry as they approach high excursion the resulting distortion consisting of 2nd and 3rd will sound quite musical and compensate for the effects of power compression. also no one has mentioned dispersion. unless the speaker has constant directivity - at least over the vocal range - it won't sound natural because there will be a difference between the response of the direct and reflected sounds reaching the ear. there is no way to record and reproduce all live music perfectly as many musical instruments have significant directivity.

Yes it's a difficult one bass,we feel it and hear it but there is a whole array of differing perceptions, personally I prefer as close as clean , undistorted as possible, I think my HiFi comes as close to that as I am going to get when ime listening to material that has say a double bass in it recorded live and being 35 feet or so away from the speakers....then I can hear the instrument Crystal clear, on the other hand, if I am cranking up my PA in the studio then it's as you say, it has a lot more distortion but does what it says on the tin.
On another note, I was working for a studio engineer a couple of weeks back who is right in to his Hi Fi, can't remember what his speakers were but he swore by his ribbons, seemed to know a lot about it all but I didn't get to hear em....the other thing he was in to was the input side of things, he used an Apple Mac to store his no loss music but said the Apple was rubbish at music due to the internal clock and sampling rate, anyhow, he had an external clock gizmo wired to a battery which was custom made in Denmark which he reckoned made all the difference to the quality of the sound..... Just thought I would run that past anyone interested. |

EV HR90 with DH7, it sounds better as is. Has since been replaced by JBL 2384 with 2435 Be (unbelievable upgrade) JBL 4508 cabinet with one port blocked is tuned to about 28hz. Eminence Magnum drivers with the aluminum phase-plug (sound better than the 2226 the cabinets came with). |

It(EV HR90) looks similar to the TAD 4003. Yep have to agree the 2435 Be(I use them on the vertical SAM1 horns)is very nice-Can imagine it sounding sweet on that screen array horn..

If thats how easy it is to make you buy crap then you will always get mugged
Plus 3" mids last indefinitely, 2" titanium cd diaphragms breakup after a couple of years and are fiddly and expensive to replace. 16 3" per side will cost you less and smash out 135db+, less phase problems and no standing waves from the horn. If hifi is what you really want. And yes minimum 4 way Edited by Steve20131 - 07 September 2016 at 9:56pm |
