I disagree with some of the above comments! Vibe subs are very good, and when bought alone the £80-£100 prices are fair, BUT the secret in Vibes loaded enclosures is almost entirely with the box design! this is what they specialise in, nobody does it better, and theyve spent vast amounts of time investing in this area, and always test dozens of box types for every sub combination. Their bandpass boxes in particular are astonishing and their 8" setup hits lows like a 12", the 12"s like a 15", etc. The frequency response from Vibes equipment is always exceptional.
Now other sugestions people made:
I think that buying Vibe subs to put in a different box is ok if your budgets tight, cos youre still getting good value subs without paying for the box, although its nowhere as good as a Vibe in the custom box.
But buying a Vibe enclosure and putting different subs in?!?!?!? Thats frankly mad! The boxes were designed with perfect internal resonance frequencies, cubic volumes and shapes to accomodate the Vibe subs, so using another sub in them would be a bad plan.
All IMHO.
And by the way lets all go buy Sony.
