I purchased the EssAmt1A speakers new in 1976 and I still have not found a speaker to replace the quality and sound of these superb speakers. I had them in storage in my HOT attic for 12 yrs. and found the the cone suspension rings deteriorated, I ordered a new replacement 12" woofer, installed it and the speaker sound just as good now as it did when new. Thank you, Thank you

I have had the cabinets for about 20 years with some cheap replacement speakers. I found that the quality of the customer service and the woofer to be of top quality! The price was most reasonable (less than I expected for kind of speaker)! Thanks to the staff at simply speakers for your help and advice. Greg Blalock
