I have an old SWR Bassic Black 120watt combo w 15". I just pulled the trigger for about $120 to replace the woofer/tweeter*. Used combos now sell for around $300. Did I do the right thing??? Electronics seem to work fine and I remember I liked the sound when it was working years back. I was looking for some extra bottom with the 15" for a disco club gig. Will run in parallel to with 2 Aquilar 2x10 cabinets with a GK 700RB or a Mark Bass Little Mark II. * Eminence American Standard Beta 15A 15" replacement speaker , 300 Watts at 8 Ohms plus Pyle PDBT28 1" Heavy Duty Titanium Super Tweeter.
