A better L112 ??

[mbottz]

I purchased a very nice set of L-112's about a year ago and have never been quite satisfied with the sound. IMO they sounded kind of Tinny, shallow and lacked depth. So I sold all the guts and replaced the drivers with components of an L65, including crossover. I think it made a world of difference. When I A-B compare them to my L-300's they are very similar. Good dispersion, good sounding mids, except they could use a bit more bass.

My question is, to one of the cabinet tuning experts out there is, could I benefit by changing the port size or port depth for the installed driver? Or should I search for a different LF driver?

Also Do you think the new 112 config would benefit from an LE-85 horn as a midrange?

I power these with a 250 watt Pioneer Spec 2 & Spec 1 preamp with a Technics Sl-p1300 professional CD player.

Thanks for any help you can give. Here is a pic of them setting next to my 300's

Thanks

We need cabinet interior dimensions, driver model #, and present port dimensions, i.e., diameter and depth....

[mbottz]

It may be optomistic to expect L300 bass from the current cabinet config, but I would like to see if it is possible to get a bit more from tuning.

Interior cabinet dimensions are 23"H X 12.75 "W X 10"D Port 3" dia 6" deep.

I think the driver is the 126A

Thanks in advance for any help.

Your going to have a problem simply because you dropped the 126 into a smaller box than you started with. As far as I know there are no published T/S paramaters for that woofer. If you are near someone with a Woofer Tester 2 you could measure them to get the T/S. You need the measurements to be able to model the drivers in a box program to see what you can do with the volume you have.

Techbot to the rescue?? Anyone have the TS on a 126A???

Stumbling upon this thread nearly 20-years later as I renew my acquaintance with the L112s I've owned since new for 40-years—having just given them new surrounds—I understand the fallacy of the Original Poster's premise. He should have taken the speaker complement of the L112 and put it in the cabinet of the L65. He did it backwards! The 128H has always needed a bit more box volume but it is a far better woofer than whichever of the three versions available mbotz has in his L65. And for normal use, the 077 really isn't all that compared to the silky 044! Show me that I'm wrong.

I just completed the L112 and they are happily playing atop the 240ti I recently "restored", too. Sitting in front of both of these is the L150A I'm working on next. Looking forward to another data point for comparison. Oh what fun I'm having just two-weeks into retirement.

Yah, if he wanted a better L112, he should've just opted for a set of 120ti's. Not that I've ever heard a pair, but the midrange and 044ti tweeter are supposed to be pretty darn good.

Although I rather liked the 044 tweeter in my 150A's. If only JBL mirrored those cabinets like they did with the L112's. Yours look great, BMWCCA. Glad you're enjoying retirement! Keep posting.
