That "10inch" looks exactly like a DPL12.

Well, for now, it seam to be fine. I think bass is like horsepower, more is always better. I had one DPL already and wanted to experiment with IB. I had other options for two dpl if that didn't work. I am starting to really like IB, so when I move, or atleast move my HT room, I will look a # of...

"It’s academic if the driver has already ripped itself apart." Yeah, that's what I'm scared of. How do you know before reaching that limit? I watched the drives through a heavy base piece, I could see it move through some really low sections. Could 70-75 watts/driver drive it to the point of damage?

OK, Things are looking(sounding) up. I noticed that the box didn't line up properly and tore down the box. I eventually found the addition of the second driver was holding the box from seating in position properly, so I had to do little trimming. Also, since I had it down, I made a gasket out of...

throat dimensions ~ 14"x14" - the vent dimensions ~14"x15" or 16 http://www.geocities.com/toswells/75.../IB3_small.jpg http://www.geocities.com/toswells/75.../IB2_small.jpg These are old photos taken when I was experimenting using only one dpl12. I am using the same cab now, but with two...

well, I didn't mean to be insulting. to me, there seams to be a peak in a freq range and yes I have to locate that freq and watch what mods do to it. But I thought that I could start reading up a little on room mod techniques and see what can be accomplished. I am also looking at som...

driving them with a NAD3150. Might have ~75 watts per driver @ 3.6 ohm.

Just setup an IB using two DPL12. Sounds pretty good. I know that I need a BDF, but I am now wondering if I need to look at some room mod. As I said, it sounds good, but after listening for a couple of hours there is a constant and annoying freq. Almost boomy. I didn't have this with a single...

Ok, Thanks for the help guys. Thomas, I thought that the drivers had to be in pairs and facing each other. Expanding to three sounds like a great idea, but I that will have to wait. I am thinking that an EQ might be money well spent. I had to set the driver/s down ~ 12in to clear the floor joist...

thanks, I am going to do a search on BDF. What unit are most people using and do they have one with an active crossover?

Thanks for the FAQ link Thomas. We had 40cm of snow and 80km/hr winds the other day, so I decided to experiment. I built this IB with my one DPL12 to see how it sounds. Because of the concrete wall the box is only expandable to two. For music it sounds great, it does take a little more power...

Ok, how about two DPL12 in an IB. I know the output wouldn’t be the same as two Tempest, but I have enough output from the one sealed DPL. I would just like to reach a little lower and cleaner. A vented DPL 12 would go lower, but I don’t think it would be a quick and clean as the sealed box...

Hi Thomas, do you think that two tempest would do a fair job. Remember that I am running only a single sealed DPL12 and I have adequate base, I just would like to clean it up a little and expand the usable frequency range. It does fairly well down to low 30’s and starts dropping by 27 and falls...

Ok, I need some input. I built a sealed 75lt DPL12 last Feb. It has been working great, but I would like to make, it or something else, better. My goal, to get cleaner lower base. I have a couple of thoughts. Either an infinite baffle with at least two tempest, a phoenix type dipole using two...

$119 sounds good, but I am concerned with shipping cost, exchange and duty. I seam to be limited in what I can find here in Canada. I may have to brake down, but when your looking at 45 -60% increase.:thumbsdown: I have heard of the 15" I.B. Dayton, how do they work compaired to the Tempest. I...

15", ok I'll watch for a sale. I guess i was thinking 12 because of the location that I want to put the IB. it's 12"x15" with the 15" side hard against the wall. would it cause a problem if the mouth/opening was slightly maller than the sub box.

Thanks for the reply, I am running a 75l sealed DPL12 with my nad 3150 (~65 watts/coil) I find that this setup has no problem producing enough spl for me and I might add that it also sound great. But, I think I caught the DIY bug, I want to try my hand at another project. I have the perfect...

How much power would be required to run a pair of shiva's in an IB setup. How much power before the reach x-max in an IB setup?

The Original Heresy (1957-1985), 96db spl, 50 to 17,000hz The Heresy II (1985 - ), 96db spl, 63 to the Heresy is sealed, but has a 12" woofer not 15. The Cornwall, it's bigger brother has a 15" woofer, although the Cornwall is a ported. (stats 98db spl, 38 to 17,000hz). The rest of the...

I was just considering doing the same thing. I already have one 75L dpl12 build and was considering the possible advantages or disadvantages of having two and using them as stands for my Heresy’s. As far as bass, would a second sub add more volume, punch or detail? I have been running the dpl...

has anyone tried a driver from this company. maxspeakers.net

Are there benifis/advantages between the RS digital meter 33-2055 and the analog 33-4050 besides price? The analog requires a conversion table, is the same true for the Digital one as well?

I'll see if I can pick up some rg-58 or rg-6 and give it a try, thanks.

I don't know if this has been answered or not, but I would like to make a long run interconnect to run from my computer to the receiver. The length, I'm not sure, maybe 20 feet. has anyone done this before?

I would have done the back, but the veneer that I bought came in a rolled 24"x96". This didn't leave me enough material to cover the back, another $50 + tax for another strip of veneer. I don't think that it will be out from the wall in normal use, besides I am already thinking of another sub...

I quickly through some photos on an old web page that I had, If anyone’s interested check; geocities.com/toswells/75l_DPL12 dot html jeez, I can't post a photo ar html, try this.

Well, I finally made a decision on my sub design. I figured for my needs a 75l DPL12 should fit the bill, at least for now. I am a virgin when it comes to subwoofers, or DIY projects as far as that goes. I figured that I could take the money for a plate amp and put it towards a new Denon 1603...

Hey thanks, I'll check those out. The svs list is the one that I remembered see, just couldn’t place it.

I am not sure if anyone can help, but about one year ago, I saw a listing of movies and music which hade a notable amount of low bass frequency in them. has anyone else seen a similar list?

Ok, I've stuffed my box ~1 lb/ft2. What are the effects of adding more or less dampening material or are the effects minimal in a sealed box. It sounds pretty good, however my exposure to subwoofers are minimal. I have my crossover set @ 80hz, the sub seams to mate fairly well to my speakers...
