Default cerwin vega at-15s tips on repair and remodel

i'm looking to bia mp my cerwin vega at-15s.
looking to keep the active x over network to feed the mids and highs for front right and front left and looking to run a separate amp straight to the subs with no passive xover just fed from the "sub" or "ulf" rcas from my receiver

i was going to add a "biamp terminal cup, pull out the bars and use one terminal pair as crossover sub out and the other as sub in, so by repalcing the bars the operation returns to normal.

Secondly, my cabinet started rattling. I have repaired it in the past with wood glue and large wood clamps only for the vibration to return a year later. any recommendation or repairing thes particle board/laminate cabinets, the corners are mortised at the rear and front and mitered an tops and bottoms

Lastly, i would like to change the color from walnut to semi flat, semi-gloss or gloss black and would like the finish to be durable and id liek to allpl right over the laminate or apply new laminate. any suggestions? anyone reface or remodel lamiante enclosures?
any help would be apprecated.

Ahh...AT 15s. The Pinnacle of huge *** Cerwin Vega cabs. I really wish I had a pair and somewhere to let them stretch their legs. Maybe one day I will have a big enough game room or something to have a new par.

I like your idea of bi-amping the speakers but I was wondering if you may be better with a big *** amp (something like a Crest CA4) and EQ them to sound however you want? IF you want to bi-amp them then let us know how that works out and your idea should work.

As for refinishing and fixing:
1. You will have to strip off the vinyl covering. If I remember correctly the AT line had a vinyl wood grain covering.
2. I had to run screws from the outside of the cabinet to the braces inside to "pull it together". If you are going to refinish them then you can do this and use wood filler over the screw holes that you used to screw into the internal braces.

I had a pair of VS 120s that sounded like the trunk on a ghetto mobile and I had put screws/glue in them to get the rattles down. I have been known to use big power on my big CV cabs before though. (cough cough PV 1500, Carver PM 1.5...etc) and I am sure this is part of the cause.

Default Cerwin Vega

I have a mint condition (demonstrated use only) pair of ex AT/15 bass drivers for sale -- I bought them from a dealer some years ago and they have been carefully boxed and stored in my spare bedroom.
They were taken from new but damaged cabinets (scratched veneer)
Their Fs is around 28Hz/power is 400Watt/4ohms -- have huge magnets and would be expensive for me to post outside the UK.

I was going to use them in a back to back subwoofer -- but now my room is smaller and my wife is bigger!
