Room will be approx 2500 cuFt.

Budget will be around 2000$ CAN.

200% for HT use only

Choices:

Chase HT:
2 x SS.18.1
2 x VS.18.1

DIY :
2 x Mach 5 UXL-18
http://istonline.ca/mach5_uxl_18.html

2 x Mach 5 FTW-21
http://istonline.ca/mach5_ftw_21.html

Is there anything that would suggest that 2 UXLs in a sealed box of 34x31x22 would outperform the SS or VS?
Would the 21" subs besides the awe of being 21" bring something more to the table?

The costs involved (boxes,design, woodwork) would bring the Chase and DIYs to about the same price point. I've taken the price of amps into consideration.

I've owned SVS, don't want ED or Epik or HSU. No one else I know of makes affordable 18", wouldn't want to go smaller.

I'm basically looking for the cleanest, hardest hitting bass in my price range.

Give me your thoughts, opinions, links ...whatever you got..I'm all ears.

Yes, the UXL-18 is a monster of a driver: http://www.data-bass.com/data?page=driver&id=37. Based on this testing it behaves nicely up to and beyond its listed xmax of 34mm. I don't know much about the driver in the CHT subs but I don't believe it's even a close comparison. They do list the xmax as 19mm on their product page though: https://www.chasehometheater.com/index.php?option=com_virtuemart&Itemid=143&vmcchk=1&Itemid=143&redirected=1&Itemid=143 (1.5 inches peak-peak = 38mm peak-peak = 19mm xmax).

Yes, more displacement. Same 34mm xmax but with 1640cm^2 of cone area vs 1029cm^2 on the UXL. A pair of the 21 would provide the same displacement as 3 of the 18's. That said the UXL-18 is a much sexier driver. Also I'm not sure how they compare for your intended use (enclosure size, intended tuning, etc.).

I would go with the DIY without hesitation - it's not even a close decision. That's just my opinion though, I've built several subs/speakers. Some considerations on going DIY - do you have the tools/ability to build the enclosures? Have you played with any modeling software yet (WinISD, Unibox, etc)?

The enclosures is I went the 18" route would be built by a carpenter. Looking at 450$ for 4 boxes just about. Actually more expensive if I have him build only two lol

I haven't played with any modelling. Was planning on using NEO DAN's easy 24" CUBE...

Being able to get my hands on 4 boxes also opens up the door to 2 x UXL vs 4 x IXL.

If you do go the DIY route open a thread in the DIY forum for suggestions on box size rather than choosing something arbitrarily smile.gif
