CELESTION TSQ1545

こっちの方は、スペックが変更されています。

以前から気づいていたけれど。

写真の具合か、外観の印象が変わったね。

相変わらずの男前。

ともあれMms 260gから187.8gになり、いやぁ、これなら普通に使えるな。

スペックの記録は大切だね。

CELESTION TSQ2160

いつの間にかTSQ2160が発表されてる、というか、当初のTSQシリーズのリストには記載されていなかった。

でもまあやはり、6インチボイスコイルの21インチ出ちゃったか。

2145は早まったとも言えるが、こういうのは巡りあわせだからどうしようもない。

とりあえずスペックを記録しておこう。
