1hiep0,PA, live band, been using Community SLS920 for years love the SPL only problem it's weight 70 Lbs, hard to lift on stand by myself.
I am looking to build something similar but on a diet <60lbs. SPL and weight are the main criteria. Thanks
I was thinking about doing a MEH project but don't have the time because of its complexity and hard to get it to work right .1hiep0,
You could reduce weight below 60 pounds, gain some coherency and equal or increase output using either a multiple entry or coaxial horn design using neodymium drivers.
It would be an expensive and time consuming project to complete, though could improve sound quality if well executed.
I was trying to do that, being an old guy (low 60) it's tough, at the end of the gig it's feel like it's not 70lbs.Or you could put the SLS920 on the stand while laying on it's side, then stand it up- much easier than lifting on to the stand by yourself.
And use this as a guide?I love the weight of your SynTripP could it be modified to add 4 celestion mids while keeping the same dimension?
I'd just use the same dimensions that Danley uses:
Midrange taps are 3/4" in diam, 3.5" from throat
Woofer taps are 2.5" in diam, 10.5" from throat
Woofer ports are 2.5" in diam, 14.5" from throat
The SynTripP is a two way design, using 10" lows and a 1.4" exit, 3" diaphragm high driver. Free space peak output is around 122 dB at one meter in the 80-160Hz range, with more headroom above that range.I love the weight of your SynTripP could it be modified to add 4 celestion mids while keeping the same dimension?
A simpler and lighter approach to reach the ballpark output of the Community SLS920 would be to to use a good neodymium 12"/3" diaphragm coaxial driver with a short bass horn, like the DSL SM80. Port the cabinet if more output is needed below around 200 Hz.
