Loudspeaker Repair

Dear All,
my go to chap for loudspeaker and hifi repairs has moved back to Scotland, and he is sadly not able to do any repairs, I live North of Harlow (near Bishops Stortford) and I wondered if anyone knows of a good reliable HiFi man / woman !!

I have two subwoofers that I need someone to check over for me, and two other subs that need attention.

can anyone think of someone, I travel a fair deal, so 50 miles in any direction is not impossible to drop things off.

thank you
Peter
