Ohm Walsh Micro Talls: who's actually heard 'em?

How do i make sure the "output is variable level?" And until I can afford a second pair of good quality speaker cables I'm going to have to go with the preamp out on the Nova as opposed to in-line anyway. I appreciate all the help, I'm slowly coming to understand how all of this works!

It should be specified in the owner's manual. Sometimes, preamp outputs are fixed-level, like a tape-out output, so that the sugnal is at a constant setting. The variable level output will be affected by adjustments to the Nova's volume control. If you are not sure, connect the preamp output to the subwoofer, lower the subwoofer's volume to zero. Put on some music, then gradually increase the subwoofer's volume control. Once you can hear the subwoofer putting out a signal (audible bass), lower the Nova's volume slowly until it is at zero. If you still hear the subwoofer, but the main speakers are silent, you are connected to a fixed-level preamp output. If the subwoofer also goes silent, you have variable level. BTW, some preamps and amps allow you to select variable or fixed output via a switch or set up program.

Anyone seen or tried the sub that John @ Ohm offers? I do not believe it is an in house design, but seems pretty inexpensive at $250 in black and OHM will re-veneer to match existing walsh models

I'm also curious about the Ohm sub. Anyone know anything about it? A picture, even? It'd be half the price I paid for the Velodyne, so maybe I'd consider swapping.

If i recall my conversation with john, the sub is approximately 16 cube, goes for 250 in black or another $150 for optional matching ohm veneer

Its a little large for my needs but the matching veneer may make up for it. If its covered by the generous ohm return policy i may take a shot...

would like to know a little more detail re amp/driver/port(??) and general performance but given that there are some decent subs coming out of china these days (REL) it sounds interesting.
