[QUOTE="skip, post: 864293, member: 1088"] Thanks for the replies. I have poured a lot of time into finding replacement parts but this is proving somewhat difficult. My only other alternative is to replace the drivers with something similar. I have found T/S parameters for the (similar) JA-3060: Thiele Small Parameter Fs (Hz) 19.6 Qms 4.91 Qes 0.29 Qts 0.27 Vas (Liter) 228 RMS (ohm) 2.6 Mms (kg) 105 SPL (dB) 89.59999999999999 Bl 15 Re (ohm) 4.4 1st prize would be to find something similar so I don't have to modify crossovers or the box. Where do I even start looking? As a last resort I would have to find the closest match and fall on the expert knowledge of the forum members to assist with a new crossover design. The latter 2 suggestions fall way beyond my knowledge. [/QUOTE]
