Two weeks ago I built two boxes for my Jordan JX-92S drivers based on GM"s 40" MLTL design. The boxes have a triangular cross section. One additional twist I put in was to use a relatively wide and tall front baffle, about 17.5" wide and 60” tall.
The result was surprisingly good. The bass, although a bit shy and not too deep, is really not bad considering the size of the drivers and that the speakers are far away from the walls. The imaging is very good, and the soundstage is wide and deep. The tonal balance is quite pleasing. I did not use any baffle-step correction.
Before I tried GM's MLTL design, I was not too happy with what I got from the Jordans on open baffles or sealed boxes. I was about to give up on them. I decided to try the MLTL design mainly because it was such a simple project, and I did not expect much from the design. Somehow the MLTL design works, and I need to figure out why, but I am surely glad that I did not give the Jordans away.
As testament to the good sound of the Jordans in the MLTL boxes, my wife was listening to two Pink Martini CD's she just bought through the Jordans, and she was very impressed by what she heard. She commented on how clear the sound was, and how she could sense that the music was performed in a hall. She is not an audiophile and is normally very picky and was rarely impressed by the many speaker projects I tried, and I was surprised that she talked about the “hall” sound like an audiophile would do. She thought that the Pink Martini CD’s sounded better through the Jordans than through my big system using B&G RD75 drivers and eight 18” woofers for dipolar bass, although (apparently to avoid hurting my feelings) she emphasized that her preference was limited to the two particular CD’s. I have to say that listening to the Jordans in the MLTL gave me the urge to go back to tweaking the B&G system, and perhaps with some digital EQ the B&G system will leap-frog over the Jordans to be again the clear winner. We shall see.
A big thank-you to GM.
