  7. 15 inch build - TC LMS vs Dayton Mk4

    DIY Subwoofers - General Discussion
    Hi All, Looking for some feedback in terms of which build makes sense. I already have the flat pack for a 100L box. I also have the option of using a iNuke 6k or LG clone. Would running the LMS at double the 'datasheet' RMS be a major issue?

    Hi Folks, I wondered if you could give me some advice here. I decided to build 2 x sealed enclosures for 2 LMS ultras that I brought. I used 50mm mdf to give me the least hassle building two layers and due to lack of tools/clamps etc. The boxes are around 3.5 cubic ft but (taking the...

    DIY Subwoofers - General Discussion
    I have killed one of my SDX15 again. This would be the 3rd time, so I have realized that I cannot run ported subs for my HT because I am asking for too much sound - 2 15s won't do it, and their demise is either thermal or mech. So I have found 2 used LMS-Ultras from trusted guys for $1500. OR...

    I've been reading through this forum and I apologize in advance for beating a dead horse. But none of the threads I found answered all my questions. I'm VERY new to all this stuff and I kind of jumped in head first. I have a LMS 5400 Ultra in a 21" cube enclosure that I have yet to see as it is...

    I have bottomed this subwoofer out already and you will be happy to know that the cone dents on the 11" spider box before the coil hits the back plate, which is a good thing IMO (bottom less design, check!) :R I'm finding that the iTech-8000 likes to produce more current than voltage, and...
