Reggie on 09/09/2020 3 star rating

ok sub, would be nice if it sounded a bit deeper and louder

Andy on 08/09/2020 1 star rating

this died after a month. Not built for decent bass output

Adam Philips on 02/09/2020 1 star rating

Bought this unit, went faulty after 8 days. Sending back for an exchange. Might opt for another sub
