I have extremely high recommendations for Low Down Sound's cabinet builder Don. He spent a tremendous amount of time with me working through what I was looking for and the alternatives. What I ended up with is a pair of 2x8's at 4 ohms, one with a tweeter upgrade and one without. The cabinets are built solid and flawlessly. They're punchy yet project an unbelievable amount of bottom end for such a small footprint. For my needs, playing in an 8 piece horn band at medium sized rooms (seating 150 +-), there's nothing that it can't handle. The upgraded tweeter is sweet sounding not brittle and gives the cabs just that pinch of extra clarity I need to play finger style yet isn't abrasive when I occasionally pop the g string. Together they handle the low b very well. Now for the good news for us old farts...these cabs weigh in at a total of under 65 pounds for the both of 'em together. They're extremely portable. Here's more good news....they're a fairly cheap date. I got them delivered for under $700.00 delivered...with the upgrade. I think the base price would have been around $600+ delivery. He used Eminence (I think) long throw woofers in this cab but can get you Neo's, "normal" ceramic mag speakers or whatever ohmage and wattage you want. The one without the tweeter is excellent for my Rob Allen fretless 5(probably for you upright doublers too). They remind me soundwise of the Aguilar 112 I used to own but with a little quicker response. They're smooth and punchy, I feel they're slightly scooped mids wise and need a slight boost of my mid preamp on the bass to make it happen best for me. For the person that wanted a rectangular 212 cab, maybe you should be calling Don at LowDownSound for a price? THANKS FOR LISTENING.
