delta 12LF/KSN 1038 experiment a success!


I was not sure whether the Delta 12LF would go high enough to be
used with the KSN 1038 tweeter using no cross over. Well I bought the
parts and put them in a pair of floor monitors boxes. The sound is
amazing. I like it almost better than the 2pi studio. There seems to
be less of a 'shout' in the midrange. A look in the Eminence sensitivity
charts gives the explanation. The Delta 12LF rolls off sooner
than the Alpha 10 so it integrates with the KSN1038 much better
since there is almost no overlapping of frequency response. I was
afraid that there would be a hole in the response at around 4k, but
there does not seem to be any. The floor monitor is only a 1 cubic
foot box, so the bass suffered, but not that much. In room response
starts to roll off around 70Hz. These will have excellent bass if
the box is the size of the Theater 3pi or about 3 cubic feet.
The KSN 1038 high end is not as good as the PSD2002 so these cannot
match the Theater 3pi but for $160 a pair (not counting the wood)
since I already have the boxes, the price/performance ratio is
excellent.
