Hi, I want to sell the REL QUAKE SUBWOOFER for sell. REL is a British Speaker Company who only made audiophile grade subs.For more information about the brand please visit www.rel.net.With its downward-firing 8" drive unit and sealed-box enclosure, the REL is not fussy about positioning than some models using forward-firing drivers and ported bass loading.When you consider how little space this subwoofer occupies — it really could be hidden away under a coffee-table or beside a sofa. It is in perfect condition & without an any functional problem. Made in UK and also purchased from UK. For any information sms - call but visit its web site first.Thank you for your interest.
