I very, very rarely write a post like this, but here it goes... I ordered a 15x8 cab from Jorg at Schroeder, approx 8 months ago. Initially, I wanted an 8 ohm cab, as to potentially utilize with a second cabinet. Jorg encouraged me to go with a 4ohm cabinet. He claimed he had a "box" that would enable me to run both 4ohm cabinets at a 4ohm load. He said he would include the box for free. I ordered the 15x8. After receiving the 15x8 and feeling that I really did need more on the top end, I ordered a 12x10. 4 ohm, as well, per his recommendation. As of this date, approx 9 months in to the deal, I STILL have yet to receive a functional "box." He sent me a "box" with speakon jacks, but two of the jacks won't receive cables whatsoever. The cabinet configuration has been utterly useless to me, seeing that my bass rig won't run at 2ohms. I have reached out to Jorg many times. He continues to promise me to get me a functional "box", but, it never materializes. After so much back and forth, I finally emailed him, yet again, telling him to please send me the promised "box", so I can sell the damned cabinets and be done with this... His response? "My engineer had surgery and is in the hospital. Sorry for the delay. Things happen." I would HIGHLY encourage anyone looking for custom cabs to go elsewhere. Jorg was somewhat helpful in taking my cabinet order and my money, but, when it came to helping actually utilize the product they built for me, Jorg has failed. I'm sticking with my Berg NV 15x6's, which my band prefers anyhow. Low end is much tighter, than the Schroeders. Sorry for the negativity, but, that's my Schroeder experience.
