Hey guys, I've been doing all the research I can, regarding the various options I mentioned in the poll and others suggested by various members.
I spent some time checking into the SH-50, but I read something about each Danley product measuring different. As in, you have to physically request that the products that you order match/measure the same if one was to use them in a HT environment. I don't remember if it was at this forum
or the thread here on AVS
started by TheLion, but it turned me off in general. I don't necessarily want to give up on the SH-50's, but it would be nice to hear them in a side-by-side comparison against something like the Noesis.
With that said, I have been reading more and more positive things coming from the Noesis and at about ~$2,500 per speaker they seem to be reasonable for the amount of claimed performance. Hell a 7.1 setup should, in theory, easily yield 140db+ performance. I'm leaning towards that, because my taste for expensive drivers will eat up any budget that I have just by purchasing the raw drivers alone.
I feel like I need to re-structure this thread as I have made my request too broad. How about this. I am going to draw a line in the sand right here and use the JTR Noesis as a benchmark (even though I have yet to hear them for myself?!?!) for this DIY project.Summary of new DIY Perimeters/Goals per speaker (Subject to change upon finalizing design)
Budget: $2,000 - $3,300
Design Type: Two-Way
Max Output: 140db
Response: 80Hz - 20+kHz (+/-3db)
Impedance: 4 ohm
$2,000(if passive) $3,300(if powered)
- If I decide on a passive design, I plan to utilize a few of those Lab Gruppen Clone amplifiers I have heard about. I've researched plate amplifiers and the most powerful ones that I have come across seem to come from a company called Speaker Power.Design Type:
- Highs and mids. Would like some nice mid-bass with extension as flat as possible down to the 80Hz region. My initial thoughts are that the ONLY way I could achieve this on the high-end is with a compression driver. That's totally fine.Max Output:
- I want this figure to be max "usable
" output per speaker. Based on the commonality among our hobby and using the Noesis as a benchmark, I understand I am essentially asking for x 2 the performance for a 6db gain over a single Noesis. Double the performance for roughly the same price is what DIY is all about, right gents?!?!Crossover:
- Unless there is great easy solution available, I will need some serious help here gents. I am still learning the crossover game and couldn't tell you the difference between an active and passive crossover at this very moment so I will be doing what research I need to in this end to understand the basics. I do know that I do not want to have to rely on an external DSP to send the correct frequency range to the mids and another channel of a DSP for the highs. Am I making sense?Response:
80Hz - 20+kHz (+/-3db)
- Again, as flat of a response as possible would be ideal through the entire range would be optimal. With that said, I understand the Speaker Power amp comes with a built in DSP that could help accommodate this need. On the other hand, if I went with a passive cabinet, would I have to rely on the internal cross-over to manage the incoming power accordingly?Wattage:
- I'm thinking somewhere between 2,000 and 4,000 watts RMS. If going passive, I don’t care if it takes 2000 or 4000+ watts for the speakers to reach their full potential. At the price point of the Lab Gruppen Clone amps, I will accommodate whatever power is required within that range. If I made the cabinets active, it appears as though I could squeeze roughly 2,500 watts from the Speaker Power SP3-1000-1000-500
- If a passive cabinet, I would like a simple 4 ohm speaker terminal or even speakon connection. One and only one connection! I do not want to have to bi-amp this cabinet. In theory, if I did not have an external amp, I would want to be able to hook this directly up to an AVR.Dimensions:
- Manageable enough to fit through a door and shallow enough to fit within a column, so less than 30" deep.Materials:
- I really have no preference of construction materials.Weight:
TBD (preferably under 400lbs)
- It would be nice to be able to unhook a few of these, pack them in a work van and haul them to a speaker comparison get together. However, if that's not feasible given my above requested goals, don't let it be a determining factor for whatever recommendations.
I understand there are a few issues here that I have not addressed. Issues such as dispersion, etc... I haven't brought them up, because I know nothing about them. I want to create a great performing speaker cabinet that will give me, and the rest in my theater, the full 7.1 experience.
I've updated the first post to reflect my updates.Edited by enterthedragon - 11/21/12 at 10:44am
