Moin already in a different topic here I wrote that I want to renew a part of my system So I have a power amplifier now! And that’s a impulse SD 500 for 100 Euro at E-Bay! But now I still lack a suitable sub to have read what should be good about a Sony XS L 121… what do you say? so I would like to have a 10 inch so 25 cm with RMS power in direction 300 – 400 Watt or what to the SD 500 should have the 400 Watt RMS…. would also go a good bass box…. Preisrich 60 – 80 Euro Bin Grateful for every tip or suggestion Greeting MoD1985
