It only takes once. My cats stay out of the subs afterwards. Of course, each new box needs to be explored when I first drag it in, but it only takes once. Their tails get really big.

Does anyone know of any alternate cheap(er) drivers than the Dayton Audio RSS390HF-4 which has increased in price quite a bit?
post #123 of 155
Dayton DVC15

or

MFW15 (if you can find one)
post #124 of 155
Thanks Scott!
I had forgotten about the MFW, but like you said they may be a tough find now.

I should have never sold my THT, I now need an outdoor party sub. A THT and some bedliner would fit the bill nicely.

I have a pair of Tuba 30's I'm looking to sell.

Sounds great, but that would be a tough shipping endeavor.
If you were closer I might take you up on that.

AND I might want to keep the THT around for dual purpose HT duty where the extra extension would help.

But the Tuba 30 would be ideal for my party sub idea! I may have to reconsider the THT thing.

I have a THT collecting dust in the garage, are you anywhere near rochester ny?

It would be about 5 1/2 hours. Unfortunately, it would cost more in gas than to build the THT. Damn, these gas prices suck.

I appreciate it though!

Pfft! You got that right! Been paying ~$4.30 a gallon for the past month.

It is painful to say the least. Used to not even consider the cost when running around, now its a major factor in everything.

I'm heading to Michigan in a week, Detroit, Lansing, and Spring Lake. Then continuing to Chicago. Is that any closer?

Unfortunately not.

I am in Johnstown, PA which is 60 miles east of Pittsburgh.
Detroit and Chicago are about 6-7 hours away...

I'll be in Warren PA next weekend before I head to MI. Could maybe meet in between.

That's closer for sure, but still the better part of 175 miles.
Hmmm, at least that would only be ~$50 in gas if we met halfway.

I am not sure if I am going to be available next weekend to make the trip.
If I am, I may hit you up on that offer!

PM me with what you might want for it and any details and the like.

The only problem I see is that it will have to be pretty cheap to justify the purchase/sale. I can build one for the cost of driver $159.29 and two sheets of ply $50. So, when I factor in the price of gas ~$50 (I have all the other crap like wire and terminal cup, PL, brads, screws, time, etc.), you might be further ahead to hang onto it unless you want to dump it cheaply.

I had almost $600 in my F20 when I built by the time I added up speaker, wood ($150), and "other crap" ($200+). I would guess the cost of the THT would run about the same. And that's not including something for his time invested in the build.

$600? That's the highest I've seen for an F20 and/or a THT. Did you put a nice finish on it? Maybe you're factoring in the amp?

Whoa! $600!
We built several of them for just under $300! (the driver was under $150 then and I just spray painted them)
Damn! Unless other "crap" means amp and EQ....

I guess it depends on what type of wood you are using as well. I usually found some sanded ~1/2" ply for around $25 a sheet before coupons.

Plus, I don't want exotic finishes, just semi-water resistant, ala bedliner.
post #138 of 155
Oh yeah, I forgot about the amp.

My bad.
post #139 of 155
More than the cost of materials is the cost of time it takes to build the THT. I think were forgetting the added value a completed box is worth when factoring in the time it takes to build. For me, my time is worth much more than money. It's my greatest asset and I value it highly and use it frugally.

i have about the same in mine - i know lilmike's original plan was for a cheap sub, built primarily out of stuff he already had. I splurged on an oAudio 500w amp, higher grade 3/4" mdf, heavy duty rubber feet, nice terminal cups and wire + cable pants/techflexx to make it fancy, and the more expensive dayton driver.

then i spent another $150 in gas to go pick it up from my friend who built it 6 hours away.

it's still about 25% of the cost of a commercial offering with the same level of performance, which is how i gauge my cost savings in the build.

Ya, no doubt. Some people have more or less or it, just like money.
I enjoy the builds and they go typically quickly for me since I was using my friend's wood shop with the right equipment.

I have plenty of time and typically have some disposable cash too. But, sometimes it is a matter of priorities as well. There is definitely a time value of money, at for those of us that work for a living.

You can definitely make it cost as much as you want to spend. You definitely built a heavy duty version. I was hoping more for as light as possible so it can be moved around relatively easily.
I did build one with casters and skirt and higher end terminals, etc that did run close to $400.
post #143 of 155
I think mine cost around $500, probably a bit less, I never added up the receipts. But I did use my build as a reason to invest in tools to be able to build it better than I would have been able to otherwise - and faster. I'm not great at woodworking, but using lumber as a medium for building things is a hobby of mine so I welcomed the build with open arms.

Mine was probably around the $400 mark including an extra sheet of ply and other materials.

This THT has me wondering what else is out there that could perform on this level and might be in a smaller package. Would a single sealed LMS-Ultra 5400 in a 4 ft^3 box powered by an EP4000 be able to keep up with a THT? I saw Edogg's build and am thinking about building one of those to try it out.

Yes, the LMS is a monster. I also have two of those in my system.
The kick as and will go as low as you want and will take just about all the power you can give them.
The THT is a great budget solution, but much larger and doesn't plumb the depths like a sealed setup.

How high can you crossover a THT? I'm wondering if I can get a more powerful soundstage above 80hz. Right now my relatively anemic 6.5" mids seem weak with a THT filling up the bottom. To my ears at least, this leaves that 100-300hz range lacking in power and fullness.

The highest crossover would depend on the amp for the sub, I think my Dayton 240 is 180 Hz, but depending on setup it may depend on the AVR setting too if you use pre out.

No direct radiating top loaded with 6.5s is going to keep up with a THT, not unless it's loaded with at least four of them, if not six or eight.

I have Def Tech BP30s so I have eight 6.5" drivers and two in my CLR3000 center.

I'm using the pre-out from my 3808ci though I haven't checked how high the AVR will let me set the crossover. The amp is an EP4000 so that shouldn't be a hangup as far as crossover is concerned I don't think.

I guess I'll go home tonight and experiment a little bit to see how it sounds.

the 3808 gives you a lot of flexibility in tweaking your channel crossovers, independent of one another - I believe you can go up to 250Hz.
