Let me guess ... the tweeters are blown? If that's the case then I suggest a 1" dome tweeter as a replacement. They are quite cheap and you just have to match the efficiency and come up with a highpass filter that will work with the existing crossover. You might need to add an Lpad to the...

I can only suggest building your own with grille cloth and thin MDF say 3 or 6mm. Can you make a recess in your pillars so it all sits flush?

Hmmm, I wonder if you actually really really mean that! (This reply will test it out .... ) You want to build your own? Do you like the sound of cinema speakers? Start with a digital active crossover - Behringer Ultracurve DCX2496 and we'll go with a 3 way using pro drivers and amps. Start with...

G'day Michael! I found your thread while looking up the Nad receiver! Not sure if you are still looking for responses, but here are my thoughts. I'd stick with your receiver, but consider some of these upgrade options. 1. Active crossover - 3 x 2 way to cover the 3 front speakers - eg...

Peerless XLS 12" is a good one to consider. It's not the latest thing, but it's distortion is very good. It's quite happy with a small box. I also hear good things about the Dayton Reference subs, although I can't say I've had experience with them.

Well, both Robert and I agree that 2 is better than one if you can get away with it. If you can't get away with it, then 1 will have to be enough. On the question of whether 1 is enough or not, that's a personal decision, and we can't answer it any more than we could answer if you prefer to...

He already has two subs, and two are better than one in many ways. Why just use one? Even if one gives enough output, better to have two operating with less power to each, lower excursion, lower distortion. Also placement can give a better room integration. Another option with the surrounds...

Walt, I would avoid using those unless practical considerations override performance. Is in-wall an option for you? I think you will find it more realistic. In-wall has quite a few advantages. Efficiency is one of them, as well as integrating them into the room without boxes on the walls...

Brian, my thinking was similar when I first tried the idea - it was like subwoofer headphones - more bass for me, less for everyone else. I actually set up my two subs in different positions for a few weeks, all of them near the couch (either side, behind, a little in front, etc). The reality...

I'll tell you something I wish someone had told me before I bought those AV12s. They are really only home theater sub drivers, and I suspect that driver you are looking at is the same. I've tried many different things to try to get them to sound accurate for music, nothing worked. I've tried...

My guess is that it's not going to be a great option from a performance point of view. I've experimented with many different placement options. At one stage, I favoured the idea of placing subs either side of the couch, mainly as a way of increasing output and overcoming room modes. In sims it...

I don't have experience with that driver and can't find parameters for it but I have a pair of older drivers that are probably similar in terms of amp requirements - AE speakers AV12 - 2 of them with 23mm xmax and manufactured by TC sounds. Mine have dual 2 ohm coils which I wire in series to...

Robert is right - you can't make a vented subwoofer that small and get a good result. If you want to stick with that box, your options are: 1. vented with an 8" driver such as a Tang Band - you would need to simulate it to see if you can get decent performance, but this isn't a great option...

Yes, I'm sure I have the right power supply. I have bought three of these things. One for a purpose it's clearly not suited for (component video switching) and two for audio. Only one was used in my system. I had a problem with some very ugly distortion on female vocals in particular. I...

Well it turns out they are messing up my audio as well, it seems they are clipping on vocals! These things are a bad idea!

There are no trimpots at all. Could I put a dual gang pot on the video outputs to get it back to unity if this is the case? Say try a 10k pot?

I purchased two AV swithboxes for my brother in law for audio and component video switching. They are remote controlled units to replace his el cheapo manual slide switches. The cheapies worked fine, but the remote units stuff up component video! The image is ultra saturated. We tried all 3...

Jim, thanks for the response. I've had a look at projector central already and found it helpful. What I'm looking for is a "real world perspective" from users, the kind of advice you can't generally get on websites. I don't think I'll have a problem with rainbow effect, I've seen the Infocus...

Hi guys, I'm looking for my first projector and its a bit of a challenge! The room is less than ideal - a semi dedicated room with curtains that don't block out all light and a room layout that allows a screen with 1.5 - 1.8m as a maximum ie 5' or 6'. For DVDs mostly although I may use it for...

Steve, if your goal is to match a comercial cinema at home, ie serious home theatre, you will find most hifi speakers tend to fall short of the goal, unless your room is very small. Let's consider a typical hifi floorstander with a pair of 6.5" midbass drivers, dome tweeter in a vented box...

I think you will find your mains will not keep up. I have a pair of 12" sealed AV12s and my 6.5" MTM mains really can't keep up with them, even though I use a 4th order active xo on them at 80/2.4k. I get about 6db more out of them than the passive version, still the subs go further. While it's...

I have the Adire paper (PDF) which has the calculations for how much sag you will get, if anyone is interested shoot me an email. Regarding storage, I find putting things you don't need easy access to in the roof space (Australian version of attic) is a good way to free up space. I'm not...

Steve, it is an unavoidable fact. Adire used to have a paper to calculate if the sag was acceptable, however, even in that case there will be some sag over time and compromises in performance. It's up to the individual to consider how much compromise is acceptable. The Adire paper suggested 5%...

Very impressive set up you have there! :emoji_thumbsup: Do you have more space behind your screen? My first choice would be IB given such extreme VD. If not IB then a sealed box as big as you can get as this will. reduce the damping effect of the sealed air spring. This gives the best...

Randy, the hardest part with WinISD pro is entering the parameters as it won't allow parameters it thinks are wrong! This means it almost never accepts all of them being entered. What you do is enter the most critical ones, and let it calculate some of them automatically, just check they are...

Randy, I downloaded the Adire plans probably 2 yrs ago, but you really want to model them with your drivers applying max amp power that you have. "Worst case scenario" refers to the point where the vent velocity peaks. There is a point where this occurs and the velocity falls off rapidly above...

Randy, keep in mind that you should ideally allow for worst case scenario. I currently have one of my subs with a 4" vent with no flare and I have never heard turbulence in use. However, when I run test tones I find when the driver really starts to move there is a LOT of turbulent noise. There...

Whenever I have looked into Denon HT receivers, they have been specified as stable down to 6 ohms. I would be wary of using one of them for 4 ohm speakers, since HT can place great demands on an amp. Unless used by someone who is going to be moderate with the volume control, I'd be wary.

Randy, I would model it to see how it looks. I would also check the vent velocity. How many flared vents do you have? I would expect a 15" driver such as that would prefer 2 x 4" flared vents of 1 x 6" flared, but a lot depends on the design as you can reduce vent turbulence by: * using a...
