Velodyne prav fajn zgleda. Minimalističen in nič okrašen.
Pridi pogledat. |

Saj, ravno zato, ker me neprestano voayerstvo dizajna v audiu trolla napišem tako pripombo.
Torej, kdo koga trolla ?

Nisem neobčutljiv na lepoto dizajna.
Če bi zmogel, bi takoj posvojil Final Sound 1000 elektrostate. Zame eden viškov lepote združene z 'dobroto'.

| ambasador je napisal/a: | | vojcb je napisal/a: | Leta 79-80, ne vem točno, sem si naredil zvočnike po zagrebški reviji SAM, z zvočniškimi enotami RCF in S.I.P.E. visokotoncem, to je bilo namenjeno bolj klasični glasbi. Sistem je bil zaprt-kompresijski.
Pri poslušanju glasbe z nizkimi frekvencami, jih nisem samo slišal ampak tudi čutil, notri v črevah, kavč pod mano je kar drhtel.
Imel sem Velodyne SPL 1000 Ultra, vse se je treslo, luster je skoraj dol padel, ampak tistega v črevih pa ni bilo... je pa res, da se z nastavitvijo suba nisem nič ukvarjal.
Trenutno imam BR., ampak, ko bo, če bo, pride nazaj kompresija. 
PS. imam občutek, da so si proizvajalci zvočnikov z BR., samo prihranili stroške, ne bom pa trdil, da BR igra slabo, so ga dobro doterali... |
Ta tvoj PS (post scriptum, pripis) pove bistvo ! |
Tako zadeva deluje na mojem sistemu.

Ko sem kupoval svoje floorstanderje, sem jih zato, ker je avtor testa posebej pohvalil moč, globino in preciznost basa, predvsem pa je bil fasciniran nad tem, koliko signala prenesejo brez klipanja, tako da opravljajo ti floori vlogo subov, medtem ko pol metra za njimi ob steni stojijo boxi, ki samo spominjajo na sube, dejansko pa sem jih naredil tako, da v zelo majhnem ohišju, obdelanem in narejenem tako, da je praktično imuno za resonance, z luknjo, brez porta in z 3db manjšo občutjivostjo od floorov, proizvajajo suh in za razliko od floorov, ki grejo nižje od teh, zelo direkten bas, ki mu bližina stene doda pravi šut in šele kombinacija obeh parov bas kišt, da tisto pravo.
Vse to kontrolira Yamaha končna z 2X500W sinusa na 4ohm, ki je v globokih basih(die, Rotel končna, you cant handle this) v tako veliki sobi kot je moja, prava prasička, ožičenje je domače, solid core DIY Kimber kopija, v kištah in do kišt enako, licne in razne parice in podobno, zvok pri tako visokih nivojih signala zmažejo, poskusil vse možno in je delovalo napram Kimber DIY bolj mlahavo kot ne.
Od tega je boljša srebrna 1,4-1,6mm žica, žal, je tudi krepko dražja.
Tako sem našel svoj Silan za vedno čiste base in od takrat naprej so moji notranji organi vedno optimalno zmasirani, enako tudi notranji organi mojih domačih do dva štuka višje, zato najraje teram, ko grejo tamladi zdoma.
Edini stranski učinek je, da po slabi uri uživanja v masaži pristnih at stage basov, človeku rata malce slabo, zato pa Metallica, live, Nothing else matters, konkretno, ne samo slišiš, ampak čutiš, kot bi s fanti bil na odru in to kristalno jasno, z mikrodetajli, brez kaj dosti ferciranja.

Hja kaj čmo zdej, dober glas seže v deveto vas. 
Mi je prišlo na uho, da so na arhitekturi v redni program že vključili kolokvij o načrtovanju in izgradnji temeljnih subwooferjev ...  |

Linkwitz pravi, da bi morala bit 3rd harmonic distortion nižja od 1%, da bi dejansko slišal 20Hz in ne popačenja pri 60Hz. Kateri sub ima potem 3 harmonično distorzijo nižjo od 1%? |

Ko ze...pravi tudi tole:
The best loudspeakers ...
The best loudspeakers for stereo sound reproduction are those that disappear chameleon-like from the listening room and simultaneously withdraw attention from the room. What remains is an acoustic scene of phantom sources and spaces in front of the listener; an illusion that the brain creates from the naturalness of the sonic cues imbedded in the recording, which the two loudspeakers reproduce. Output volume and dynamic range of the loudspeakers has to mimic the live event for the illusion to be believable.
Few loudspeakers are capable of this magician trick. A single driver, full range loudspeaker adds too many distortion cues to disappear from the scene. A 2-way loudspeaker may come close, except for struggling in the bass and with output volume. 3-way or 4-way loudspeakers can be practical solutions to the output volume and frequency range requirements. Since they become physically large they usually suffer from a non-uniform radiation pattern with changing frequency. Next to a flat on-axis frequency response in free-space, a frequency-independent off-axis or constant power response is the most important loudspeaker parameter. If a loudspeaker is directional, then it should be directional in the same way for all frequencies and at least in the horizontal plane.
Few loudspeakers are capable of this magician trick
Except for omni-directional loudspeakers few are designed with a uniform off-axis response in mind. Electrostatic or magnetic panel loudspeakers meet the polar response requirement at low frequencies, but become multi-directional at high frequencies and suffer from insufficient dynamic range. Loudspeakers that use electro-dynamic drivers on an open baffle overcome these shortcomings. Compared to omni-directional loudspeakers such dipolar loudspeakers cause fewer room modes and wall reflections, which helps them in hiding the room at greater listening distances. The absence of an enclosure to retain the rear radiation is a major advantage. It avoids frequency selective and resonant re-radiation of acoustical and mechanical energy that is transmitted into the enclosure walls and not converted into heat. Instead the rear radiation is productively used to establish the sound field in the room.
The typical box loudspeakers with a vent for low frequency extension suffer from resonant bass, delayed panel radiation and non-uniform polar response to varying degrees, but they can be built to meet the acoustic output volume needs. They are not suited to realize the full imaging and illusion potential that is inherent in stereo, because they create sonic artifacts which are distracting. Many audiophiles listen for the presence or absence of such artifacts and use them as differentiators between loudspeakers.
The best loudspeakers are able to deliver in a normal living room a believable illusion of a live acoustic event.
in se tole:
The best crossovers ...
The best electrical crossover filter is one that maintains the acoustic polar response of a loudspeaker throughout the crossover frequency range as output shifts from one driver to the next. The sum of acoustic lowpass and highpass outputs must have allpass behavior without high Q peaks in the group delay. The highpass filter section must attenuate out-of-band driver terminal voltages at a sufficiently high rate so that cone excursion decreases with decreasing frequency and nonlinear distortion is minimized.
The crossover must be inaudible
The crossover must be inaudible on program material. This also implies that the power response of the two drivers must be similar in the crossover region, and that requires special attention during the loudspeaker's concept and design phases.
Crossovers may be implemented either as passive RLC networks, as active filters with operational amplifier circuits or with DSP engines and software. The only excuse for passive crossovers is their low cost. Their behavior changes with the signal level dependent dynamics of the drivers. They block the power amplifier from taking maximum control over the voice coil motion. They are a waste of time, if accuracy of reproduction is the goal.
