Hello All,
I am relatively new to DIY speaker building. I say relatively because I have tinkered with audio some 20 years ago (boy, how things have changed!!). Additionally, I have been lurking around forums such as this for quite sometime ( I don't just jump into things) and have learned a bunch. My thoughts were to read, search, read, read, read, and read about DIY before I attempt to knock the rust off.
Now that I am through rambling, I have an idea for a project and need honest (but kind) input. I am planning to build the Cynosure for a center channel. I am confident that I can accomplish this fairly easily ( I can read schematics and plans). Where the question comes in is........ What mains mate up to the TangBand 3" drivers?
I thought about building 3 of these (2 in a version such as here...
and 1 per the PE Project showcase design)
I thought I would take the 2 boxes with front ports, turn them up on their side, then add a trapezoidal enclosure to the bottom and top to use as mains. In the new compartments I would add a TangBand 4" subwoofer crossed over at 80hz (To the 12" sub) and ported (1 in bottom and 1 in top) for a WMMMTMMMW design.
WinISd (if I'm reading it correctly) tells me that I need a .15 cu/ft enclosure for each speaker with a 1"x3.75" (in each enclosure) port to tune around 62Hz.
I realize I can build a larger base (for stability) at the bottom and still keep the .15 cu/ft parameter by using bulk-heads and false walls.
My humble request IF THIS IS REALISTICALLY DOABLE is I will need help designing a crossover for these speakers. My Yamaha HT Receiver is rated to be 6 ohm stable. I plan to use the settings on small so as to not cook the drivers, but I have yet to master the art of crossover design (actually, I have only built them from kits). If I add (2) 4" subwoofers, once they are wired in to the channel, what woud I have to do to preserve the 6 ohms required by my amp? Is this something I can do with only the crossover for the 4's? Or, will the crossover designed to drive the 3's have to be scrapped and a new one designed for the whole kit-n-kabootle? As stated earlier, I plan to place the 4's in SEPARATE enclosures to preserve the integrity of the original Cynosure design.
I have read the LSD cookbook 6th ed. (I own it). And have researched the topic of DIY since early December. I want to get it right when I pull the trigger, or at least be reasonably confident that it will work.
I feel I have learned much, but, without feedback, I do not know where I am in the learning curve.
Before you ask why I am bent on building a design such as this, I am a sucker for multiple drivers ( I like the concept of spreading out the surface area.... and it looks cool (at least to me). In addition, the Cynosure is also a cost-effective design for me. a little over $600 (for 3 units) plus the cost of (2) 4's and crossover parts and I can have my HT LCR complete.
I realize this post is rather lengthy, but I am tyring to answer most questions about what I am attempting without sounding like a fool. However, I am sure I have left something out.
This is a wonderful site! You guys know your stuff; any help I can get would be greatly appreciated.
