I don't know my actual timeline as I switch out stuff so often but I'll just make a list of some of what I had. 1999-Present
First sub was a quest 8" - at the time, I though it was a monster lol
Paradigm ps1000 - was completely blown away at the time
Paradigm pw2200 - was pretty happy but had heard a servo 15 as a meet and fell in love
Paradigm servo 15v1 ( Then 5 months later, a second servo 15) - was pretty happy until I heard a V2 lol
Paradigm servo 15v2 ( then 3 months later a second. Ended up with 4 within a year) - Was very VERY happy until I wanted more and went to a DIY build and never bought another B&M again.
I then switched to DIY and have done over 80 builds now ( I don't post much stuff because it's for my enjoyment and I really don't care to answer a million questions about every build to be honest lol)
2 x IXL ported 14cf monster ported subs ( awesome but wanted something smaller)
2 x IXL sealed 4.5cf boxes ( not nearly enough spl vs the ported ones)
2 x LMS ultras in 4CF boxes ( great drivers, not enough spl)
4 x Mal-x 18's in 2 ported boxes, 2 sealed ( had a great time with them, 2 were ruined in a flood and couldn't get anymore, so I sold off the other 2)
2 x Mal-x 21's in 6cf sealed ( enough output at the time, grew into MUCH more)
4 x XXX 18's ( Still sealed in crates) ( to be used in new home)
4 x IXL's in IB when basement was being fixed from the flood ( then switched for UXL's 3 months later) ( were awesome until I got a projector and had to move seating position)
2 x FTW 21's (added to the MAL-x 21's) had used them for a good year.
2 x THT's ( used them for a while but moved one to work and sold the other) great sub but didn't go low enough (dayton DVC)
4 x G-horns ( sold 2 to a friend but likely going to be buying them back for my new house)
2 x JBL 2242H to be used as stands for my Noesis speakers.
4 more FTW -21's to be added to my current 4 x 21's and single G-horn, UXL-IB and 2242's
There are lots more subs thrown in the mix that i built for fun and gave away to friends and family. I've used pretty much any driver worth using from most companys, though not all were used in my HT room, They were all tested in my living room and garage. I've got 4 more builds on the go at the moment and another 8 planned. Doing a paradigm sub 2 clone with AE 18's for a friend in the next 2 months or so.
So I should be over 100 builds by this year I'd think.
When Not came out with the clone info, it changed the way DIY was done. We now had the power to do any build, with any driver and easily power everything for under $1000. I've had over 30 different pro amps and still have 8 in storage not including my 6 x FP14 clones, 2 x ipr 7500, inuke 6000 and 2 x ep4000's.
My only advise is, never go listen to something better that what you have, it will never end
( I've since stockpiled 12 more 2242H's, will be getting 8 more FTW 21's and am in the planning stages of my new HT room. It's gonna be epic hahahaha. I will never stop, I love this hobby.
