Thanks, I think I'll try the Peerless and see how it goes. As long as I know where to start tweaking I'm not afraid to unwind a coil or swap out resistors. The Emotiva has plenty of PEQ so if all...

Re: Surrounds on a (semi)budget

Thanks for the responses. I had actually looked at the NHT Peerless MT, although the clearance prices are gone. I estimate $100+ per pair, but still well within the range I was looking at. I may also...

Surrounds on a (semi)budget

Now that I have built Zaph ZDT3.5s for my fronts, I am looking to upgrade and replace my side and back surrounds (little Onkyo HTIB speakers). My main constraint is that the sides need to be...

Re: Need advice for my corner traps!!

I'm about to start my own superchunks with mineral wool and was curious whether the intermediate support was necessary. Just wondering whether the weight of the entire stack would compress the bottom...

Re: Critique my Treatment Plan

SPL graphs of the L and sub taken with no panels, flush to the wall and with a 3" air gap behind.
Black is no panel, red is flush, and green is 3" air gap. There is not much effect below 200, but...

Im no expert, but Ive done a few builds. Access to the right tools make the job much easier: a good router, bits, circle jig and a table saw or circular saw with straightedge clamp help. Dont rush...

Re: How do you trim veneer edges on chamfered cabinets?

I will also add the snap-off knife works better for me than a regular utility knife. You can keep a sharp blade easier, and being thinner you can keep it flatter against the work surface. I also hold...

I've only done it on a 90, but I use a fresh razor knife to trim most of the excess and then sand flush. Don't see why that wouldn't work in this case.

Re: If I Win the GIK $600 Shopping Spree...

If I win I will buy a bunch of OC703 fiberglass panels, throw them on the bed, and roll around in them to glory in my good fortune. After that, I will make some more panels to treat the back wall of...

Re: Critique my Treatment Plan

Next up is testing. Just for my own education, I will test flush to the wall and with a 3" air gap.

Re: Critique my Treatment Plan

The front panels are done. They are 2)2'x7'x4" and 1)1'x12'x4" panel. I used 2 layers of OC703 and drywall corner bead for the frame. I suspect wood would have been much quicker and easier, but I had...

They must have grabbed #189 from the top of the stack as the "reference mic". :D I'm certainly glad I went with the UMM-6 from CSL

Re: Critique my Treatment Plan

The listening position is a quandary, since it is in conflict with the ideal viewing position. I may experiment with moving the mic a few feet up.

The base graph is without smoothing as noted and...

Re: Critique my Treatment Plan

Critique my Treatment Plan

Since I've upgraded my speakers I might as well do something with two boxes of 2" OC703 sitting in the garage for the past few years. What's the point of good speakers in a bad room, right?

So...

Re: Zaph ZDT3.5 Build

Build is complete. Thanks to everyone who answered my questions (especially fusseli). I am pretty happy with my 2nd speaker build.

Re: Zaph ZDT3.5 Build

I've spent the last few days listening and tweaking. This is a really good sounding design/drivers, although I don't have much frame of reference.

I don't have another three-way to compare it to,...

Re: Zaph ZDT3.5 Build

The (unfinished) LR boxes are done.

Also finished the crossovers. I put woofers on one board and mid and tweeters on another. They aren't a thing of beauty, but I kept the inductors as far apart...

Thanks, I did a fair amount of researching and couldn't find any direct references. I assume the RC part of the circuit referenced above has the resistor on the signal side as well?

Re: Zaph ZDT3.5 Build

Here was my first (and hopefully last) major screw-up. Cutting the vents for the backs of the towers, I accidentally grabbed the center and cut it, too :rant:. Choice words were thought. Sometimes I...
