Hi everybody, This is my first post here at TalkBass so here goes... I play in a rock band playing original material. I am looking to replace my two 8 ohm cabinets for a single 4 ohm cabinet. My rig consists of an active 5 string bass and Ashdown 400w head. I need a lot of punch in the mid range with good treble and plenty of lows. Do I go for 10's or 12's or maybe even cabinets with a combination of speakers. My band uses a 600w PA with a separate powered sub cabinet which I DI through (nice!). I've spent the last week trawling through all the manufacturer sites and my brain is aching!! I will definitely be trying before buying but I was wondering if any of you had any suggestions - I'm open to all suggestions. Thanks.
