As their name implies, they got started making really cost-effective speaker stands, not so much audio racks. They will make anything you want if you submit a drawing and/or dimensions, etc. and can even suggest modifications to your request as necessary. But it will have to be power-coated black steel, welded together in one configuration. OTOH, I am a fan
of adjustable racks, and to ME, Mapleshade racks are the best ones i have seen and they too will make what you want to order. They can get
expensive, although not as much as the real esoteric companies.
They will last just about forever...
