for teaching purposes.
Box size--- width 22----Height 45.5 ----depth 24 external 11 cubic ft. after driver bracing and slot port 9 cubic ft +- a few
The box has a tune of 17 hz.
This is one example of what I've read from different posst on avs plus talking to guys on the phone about this driver and hearing both in person the the HT18 and the Dayton RS460HO. When I talked to Rob on the phone it sounded like he was torn between three drivers the UM18-22, Stereo Integrity HT18 and the DAyton Audio RS460HO. The problem was the only driver he could buy today was the HT18. Rob could of bought both of mine which I would of gave him a 20$ off what I paid for them so 40 under cost today or he could buy Phil's Dayton Audio RS460's. I feel the Dayton Audio RS460ho is a better driver with a lot less distortion than the HT18 from what I've been told and has more mid bass from what John LDT02 has said. One of those drivers that Phil was selling was currently shipped to him new for warranty so at 370$ I felt that was a good deal and so did Rob. So he got in touch with Phil and I picked it up for him to save Rob a 2 hour driver each way. I eq'ed Phil's room with these subs and built the box for Phil that these drivers where used in so I have a history with them. I hope he's happy with them I really think these are some really nice drivers and well worth the money. Databass tested these driver and said that 20 mm xmax is more realistic vs what parts express has them listed at. This helped make the decision as well along with what databass said about this driver.
I pulled this from a another thread below.......
Has anyone built a cyclops with the SI HT18v2 yet?
Is that driver a good match?
My buddy is building one, and didn't know if it was worth the extra $100 for the um18 (which I just now noticed is out of stock, heh)
edit: or if it's worth the $85 for the RSS460HO over the ht18
the um18 has a little stronger motor very low end output.
the 460ho has a little better at the midbass region.
the ht18 has a little less motor and little more inductance effects, so may need a little more eq than the other ones.
if $85 is a lot of money for your buddy, the ht18 will work. otherwise, go for the 460ho.
Here’s some parts express coupons for anyone wanting the codes. I just got a shipment of parts in today from them.
