Many years ago I bought a pair of HUGE JBL speakers with glass tops from Smiths is Edgware road London. I remember my friend and I struggling to get them home in a bus, each of us lugging one of these behemoths a piece.
Got them home 2 hours later and plugged them in. They nearly blew the glass out of the window frames (102db @ 1W / 1M) at high volumes but sounded absolutely awful at lower levels.
Next day, back on the bus with these coffins and back into the shop for a change of speaker. To cut a LONG story short, the owner of the shop "point blank" refused to either exchange them or refund the money telling me I spent 2 hours auditioning them and that I was happy when I left the shop with them.
We remained in the shop for over 3 hours and even told other customers in the shop not to buy anything from this bandit as he didn't give refunds. It was at about this time I kicked one of His B&W speakers in the cone and my foot went right through it!
Needless to say the next people to appear in the shop were dressed in black and had large truncheons!
To save going to court I had to pay for a new cone (about £50) and had to live with these awful JBL things until some tone deaf bloke bought them off me for a quarter of the price I paid for them. The only consolation was the police Van gave us a lift home with the speakers which saved on a bus fare.
£500 for the JBL's and £50 for a cone and that was 20 years ago! A lot of money. Thankfully Hi-Fi shops are more concerned with customer satisfaction as oppossed to profit and will gladly exchange something if it doesn't suit.
Tell you something though... it was Fu*kin great booting that miserable b*stards speaker to bits! Always meant to go back and chuck the coffins through his window display but couldn't be arsed lugging them around London on a bus
Always remember... buy in haste repent at leisure
