Panasonic pack a lot of value and versatility into its SC-HT400K Home Theater System . the quality and feature of this system make it worth every penny of the manufacturer 's suggest retail price and a genuine bargain at the discounted price find at retailer .  setup be reasonably straightforward , although the spacing of speaker terminal be tight even for small finger . a built-in white noise generator make balance the output of the speaker a snap .  most of the half dozen sound field that can be impose on the output -- range from a intimate club venue to a stadium - while more pleasingly understate than other I have hear , will , I suspect , find little use by most listener . one of those field , however , be very effective and clever . the `` party '' mode allow the listener to walk about the room without perceive the source of sound to shift from speaker to speaker .  the sound from the speaker be unforced and transparent-at least at level that the dog and the neighbor will tolerate . the rear speaker do not make themselves obvious as a source of sound -lrb- except when the source material deliberately place the sound at those speaker -rrb- . the general effect of the rear speaker be subtly to pull sound from the plane of the front speaker into three dimension .  last year the leading consumer magazine rate Panasonic 's stand alone receiver , sa-he100k , a best buy . a comparison of the sc-ht400k 's receiver with the sa-he100k receiver do on Panasonic 's website show the two receiver to be substantially the same , with the sc-ht400k lack a few feature that its brother have . -lrb- for example , the sa-he100k be a 6.1 channel receiver ; it have a output for a rear center speaker . -rrb- if the price difference between the sa-he100k plus a set of speaker and the sc-ht400k package narrow enough , the purchaser might want to consider buy the former separate rather than the latter system .  after the foregoing kudos , why give the sc-ht400k a rating of only four star ? the subwoofer that I get with this system be defective . fortunately , there be a authorized Panasonic repair shop within ten mile of my house and the defective part be replace in a week at no charge under the manufacturer 's warranty . nevertheless , the defect be a inconvenience and should not have get past quality control .
