As I anticipated last week, two of my three 228HTRs arrived yesterday. External box appearance would indicate no gouging, piercing, or crushing trauma, so... I'm leaving them in the box till next week when my son arrives, and we set about re-fitting the theater. I wanna open 'em so bad, but I'll wait, so both of us can experience that Christmas in August feeling. Jeff said that a replacement compression driver was in stock, stateside, so we're just waiting on that, and then the 3rd one will be on its way. If I had had my wits about me, I would have asked Jeff to have them overnight
that driver to him, and I would have paid the shipping. Oh, well, opportunity missed. Now, I may end up expediting a much heavier package!
The 8 Volt-6s
(surrounds, back surrounds, Atmos) are almost all finished, and the HST-12 driver retrofit
of my 12" Titanic subwoofers, is halfway there (the other two HST-12 drivers will probably ship tomorrow... hope you're reading this Nick!)
The new (to me) QSC CX168 (8 channels for surrounds+Atmos - 90W/channel@8ohms) is here, its quiet fan is installed, it's checked out, and all its special little connectors have been received. The new (to me) QSC PLX1602 (to run bridged for the 228HTR Center channel - ~1600W@4ohms) is here, its quiet fan is installed, and it's all checked out.
I will be feeding the L+R 228HTRs one stereo channel each from one of the existing PLX3402s (~1100W@4ohms per speaker). So, I will go from bridged PLX3402s for each of the LCRs to a single PLX3402 for L+R, and a single PLX1602 for C. Are these adequate wattages for the 228HTRs? (4ohms, 98dB sensitivity, 2m from MLP, 70hz-24khz, rated at 1200W RMS)
By the way, given my overall setup (see the subwoofer portion below) do I specify the 228HTRs as Small or Large to the Marantz 8802A? I'll be crossing over the bass management at 80hz.
That amp shuffling frees up 2 PLX3402s and 2 Crown D75s (that I have been using for surround duty). I will, almost surely, sell the Crowns (although, having said that, they don't take up too much space, and it is
handy to have a test amp just sitting around when you need one). I may sell one, or both, of the excess PLX3402s, depending on what I do for my final subwoofer array (see below).
Phil Marchand has my order for a stereo BASSIS (to replace my mono version). Also, I asked Phil to modify the High-Pass filter on the new unit to 15hz, instead of 20hz. I don't know if I will end up using that filter, but, if I do, 15hz just seems a better choice for Home Theater than 20hz. They were out of the faceplates for that box, unfortunately, and had to reorder... so, I don't know when I will receive the finished product. However, when I swap out the other two HST-12s, I will be back to 4 identical subwoofers, so the mono BASSIS will still serve for this interim period.
On the subwoofer topic, it is still my intent to create One... More... Subwoofer. ("One sub to rule them all, one sub to rumble. One sub to shake the hall, and make the ceiling crumble"). In fact, I already ordered, and have received, the driver
for that project (and it's a big'un... but I'm holding back that info to surprise the bassheads with my choice). So my son and I may be able to start working on the enclosure (12-15cf) for that driver while he is here... He's going to be one busy little bee.
So... thoughts? I know some of that is not JTR-thread relevant, but this all has to be considered together.
