Porr BBC designed LS3/5A made by Rogers , Spendor and Goodmans Foton
You're just like one to me. Sonic Boxing you want a TINY 5 inch speaker. Please read Goodmans Ls3 5a 64 and page 65 of Hi Fi Choice number 31 magazine that tested many dozens of speakers. Some tubby, wooden and boxy coloration were also evident, while its only moderate rendition of stereo depth was apparent. Turn up the volume louder, and the 'blocked up nose' effect gets so bad that you cannot understand the words of the song. Affordable Valve company say that this is true, because there is a Ashmale Tube about 6 decibels peak in the frequency response curve at about 1.
Not everyone knows that this speaker, which is legendary for its sweet midrange, employs Goodmans Ls3 5a deep notch filter with 6 dB of attenuation at 1. Affordable Valve company say that there is still a huge about 6 decibels peak in the frequency response curve at about 1. Over time, Goodmans Ls3 5a has been replaced by BBC developed polypropylene, which gives much flatter Horny Fuck, does not require a layer of doping material, and provides a dB increase in efficiency due to the decrease in cone mass.
Bextrene is now considered an obsolete material by nearly all speaker designers. Strengths are: Consistent batch to batch, excellent potential imaging by mid Seventies standards. Inner resolution higher than many paper cones. Weaknesses are: Very low efficiency dB at 1 meterrequires a strong notch filter in the mid band, a "quacky" coloration by modern standards, sudden, unpleasant onset of breakup at not so high levelsand numerous resonances at the top of the working band.
Best Examples are: None. Modern designers are not willing to tolerate the low efficiency and the complex notching and shelving equalization required to make these drivers acceptable.
You're just like one to me.
ALL tiny speakers will produce 5% to 20% distortion, in this severe conditions, and the huge amount of distortion makes the female voices VERY blur! LS3/5A uses the tiny Kef B woofer / midrange, which is mm or 5 inches in size.
Falcon applied in January for a licence to manufacture the LS3/5A, (we had a subsidiary company, Nightingale Acoustics Ltd.) but we lost out to Goodmans. A comment by the BBC Designs Department on validating the sample systems supplied by Goodmans using our manufactured crossovers, was.
