Post Subject: Cheating from belowPosted by jessie.dazzle on: 5/4/2010

You and I now have what seems to be very similar situations; similar MF and HF channels, in a room of similar size.

However, I still have no operational dedicated mid-bass channels; you do. I have dedicated lower-bass channels; you do not.

As is now your case, my upper-bass is strong down to around 115Hz, maybe a bit lower.

While my 40Hz horns are under construction, I run the lower-bass channels up to meet the lower end of the upper-bass channels. Yes this is higher than I should, nevertheless, the result is good, allowing me to really use the system. Without the lower-bass channels, the sound is THIN and DRY.

The pair of lower-bass channels is more than enough to completely load the room; they are very lightly solicited. These channels consist of a single 18" driver per channel, in very large, sealed enclosures, driven by a pair of 100W amps.

Obviously, lower-bass channels should not take the place of, or be relied on to augment mid-bass, but if my mid-bass horns have been sitting there waiting for over one year now, it is in part because the lack of mid-bass is not that evident; the cheating is more successful than I would have thought.

What am I saying? You might consider building a pair of "end of life" lower-bass channels now, while waiting to get on with construction of the mid-bass horns. This would be a good investment of your time and money, as you will need them in any case, and it would allow you to really use your system again.
