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

Foster 9:

The DNA-500 has more than enough power and current to drive the Walsh 5000s. This must be a placement issue, I have measured (and heard) substantial differences in the bass output of my Walsh 5s in the main power band (~40-60 hz) with movement of the speaker a mere 3 inchs. You need to pick up a Radio Shack sound meter and a test CD with tones from 20 -100 Hz and run scans for different loudspeaker positions. Believe me, a mere few inch adjustment can do wonders for sorting out the bass.

Yes, the exact placement can make a significant difference in the bass levels I have found also as Mamboni points out.

That solid brick rear wall I recall could also be working against you...not sure anything can be done about that.

Foster, you are heavily armed well beyond most at this point with that McCormack amp I would think. I doubt that is the problem.

Could something in the hookup be out of phase?

Foster, also I do not recall if you are using any power conditioning device? If so, try running without it and see if that makes a difference in the bass impact level.

Foster,

The other thing that comes to mind is to make sure the driver is tightly secured to the cabinet. With my F-5s, there are 4 wing nuts that must be tight to secure the driver else the bass levels suffer. These worked slightly loose after some initial playing time and I found that a tight fit is key to good bass.

How are your drivers secured to the base? Is there anything that might need tightening?

I don't know the 5000s as I own the 100/S3. I think this is a a GREAT design,but my one issue with this speaker is that macro-dynamics aren't great - you need higher SPLs to get satisfying dynamic impact (vis a vis my other preferred high end designs). IMHO, if you like to listen at lowish SPLs, it's entirely possible that Ohms just won't be your cup of tea. I do, however, have a simple solution - just listen louder!
