Copenhagen Hi-Fi Club

Demo of DCN28 and Power Amplifiers; 8 March 2013

I was invited by the Copenhagen HiFi Club member Peter Hasselriis Sandberg to do a demo of some of my electronics.


Poor Man's Strad
SB Acoustics SB29RDC
Sonus Faber Stradivari




GGGGGGGGGGG



GGGGGGGGGGGGGG


PPPPPPPPPPPPPPP


FFFFFFFFFFFF

This is the measurement of the SB Acoustics SB29RDC at 1m on axis in the box
Notice the realitive flat response already form 600Hz - the wide baffle does the trick

The measurement of the Seas MCA15RCY midrange - notice the response at higher frequencies no visible break-up
and the low end suffers a bit from the relativly small enclosure

The response and impulse of the Seas CA22RNX without / with reflex-port
Notice the very small changes in response below 60Hz with / without port - in this room / placement there was very
little to gain by a ported design and the effect of stuffing the port was remarkable - much better difinition at no cost...

The measured total response "in room" at 1m on axis
as allways the response is very much affect of the placement of the microphone in the room below 500Hz


In the break the setup was discussed and some had a beer to flush down the many impressions


Intensive listening of the various setup options and presets

Thank you, Peter, for the invitation to this small Friday evening event
