Stereo integrity ht18. A little cheaper and almost the same as an ultimax. Hundreds of builds on here using stereo integrity stuff. Look em up!

Both subs are good. Depends what box type you're looking for.
Ultimax has 22mm excursion, but suited to sealed box. High BL and MMS.
Reference HO has 12mm excursion and will work in sealed or vented boxes. Lower BL and MMS.
If I had this choice, I would do some modelling in winisd first, but ultimately go with the ultimax.

Ultimax 18 in big ported box has heaps of bottom end. I built 1 few months ago and with movies it is super strong. I have it running on 4ohm bridged to crown xls2000 and it can take nearly all 2000watts. It needs lots of power to get it really going.

I was suprised that it blends well with my klipsch rf82 mains. Music is very good.

Re: Dayton Audio UM18-22 18" Ultimax vs Dayton Audio 18" Reference Series HO

I recently built left and right subs using the DIY sound group Stonehenge flat packs and Dayton RSS460HO-4 drivers as I was primarily searching for good midbass rather than extreme ultra low bass output. Before any eq, the bass between 20 and 45 Hz was way too much in my large 25' x 20' space, which surprised me. Using my Emotiva XMC-1, I used two of the eleven available PEQ filters on each sub channel to eq the bass at 20Hz down by 15dB and down by 10dB at 35Hz. This produced a flat response at the main listening position. Now for the first time, I have mid bass punch in the chest at comfortable volumes. Wife and I are absolutely loving it.

I'm very glad I went with the 460HO drivers.

I have ordered both and plan to try them sealed and ported and see which is better. I have inuke 6000 and will run all 4 in either sealed or ported. I am starting with the knock down ultimax 4cuft sealed and then building full marty's. If neither of these designs fullfill need going the folded horn gjallarhorn design.
