Hey all, I am going to have a go at building a Celestion CKT-S-TF1530e 400W compact subwoofer and was wondering if anyone else has had sucess building this guy? They recommend using a suitable active crossover at around 90Hz low pass and a high pass filter around 25-30Hz. Here is photo, the plans, and a link to the Celestion website.

Looks like fun. It won't go low for home theatre, in case that's your desire, but it will offer high sensitivity and depending on room placement, boundary gain will boost the 30 Hz levels. For music, it should offer a punchy, loud, bass. But then, I like pro drivers for audio. (You probably know this, but Qcomponents sells Celestion drivers in Canada)
