The original Legacy 1's had a switch that controlled the upper bass region. This came into play at about 180 Hz if i remember, which was too high to do any good. Most of the larger Legacy's have a big peak centered at appr 100 - 110 Hz, save the Whisper. It is this huge peak centered quite high in frequency that makes them sound bloated. Then again, without that big peak, the speakers would not have anywhere near the extension ( -3 dB point ) that they claim.
Out of curiosity, what did you use to plug the ports?
As to the treble response, it isn't all that great either. Most of them have a large peak ranging from somewhere around 8 KHz to 12 KHz or so. The thing is, without this peak, the speakers wouldn't sound balanced due to the tremendous bottom end bloat. In effect, Legacy has built in somewhat of a "flying V" type equalization i.e. boosted bass and treble without having to use tone controls or equalization devices. This keeps the "audiophiles" happy because they aren't using "tone controls", yet they get all the boom and sizzle that they desire without having to resort to Cerwin-Vega's. If you doubt this, look at the Stereophile review of the Focus 20/20's and you'll see both the bass and treble peaks that i speak of. The Classic's, Legacy 1's and Signature's also share a similar bass peak with the Classic's and Legacy 1's sharing a similar treble peak. The Signature's are noticeably softer on top.
Some of the "sizzle" comes from their choice of drivers, oher parts come from how the drivers are mounted on the baffle. What i could never figure out is why Legacy would countersink ( "flush-mount" ) the woofers and lower mids but not the upper mids and tweeters, where it really counts. As such, one can typically help reduce the "shouty" treble response of these speakers by covering the upper baffle area with felt and double sided "hem" tape. Both the felt and hem tape, which can be found at any local fabric store. Simply cut the felt to shape around the drivers and tape it in place on the baffle. The improvements in treble clarity, imaging and focus should be instantly noticeable. Sean
