Main response done wrongly AGAIN at 'super tweeter' axis. Nobody asked the factory which tweeter to use it seems and enough fuss was made before about this I remember.
As for the directivity, I'd like to play devils advocate again. Just how important is it in the scheme of a nice sound at home? Take a tweeter down too low in crossover frequency and it can 'bark' (I've had this demonstrated to me), so careful choice of tweeter is vital. Add a waveguide and it can do funny things at the top end of its range it seems - mind you, most of us can't hear that high, so maybe a moot point. I'd conform though that my Spendor BC2's (in this instance similar to the famous and highly collectable BC1) with the slightly narrower baffle, do 'image' better and stronger, but the dispersion is an even bigger mess I think...
Nah, despite currently owning SHL5's with their sweet 'nice' tones and originally selling for half the current UK price in the late noughties, the current model is aimed squarely at the lucrative lower tier of 'audiophile' people now, too many (along with a newer wave of dealers) totally ignorant of how their valve/tube amp is going to mangle the frequency response as it tracks the massive impedance rise at 1.5kHz or so (I remember intensely disliking the 5+ at first, when used with an amp with 2.5 ohms or so output impedance, little more than half that of a Line magnetic or PrimaLuna confection). Some of the 'new owner' systems I read about on the HUG alarm me greatly,
-SO - nothing really here for ASR followers to be honest.
Anyone reading this and still remotely interested, should wait patiently till 2025, when the DSP active 'D' range is proposed to be launched. THEN you may have a KH420 alternative for comparison - but not this one (the 5_+ XD is five grand here and the 420 well over eight at current prices). I still like my older models, but am well aware of their excessively 'genteel' qualities which current issue models have tamed hugely. Remember that neumann and genelec aren't generally available from dealers with dem rooms, retail 'shop' overheads and the extra profit margin needed to service that need. I suspect KH420's sold through a retail dealer network would be over 50% more expensive and ciost more than ATC 50ASL's...
