I am looking to upgrade from a 4-channel original-Advent/Advent II HT system with a Polk MTM as a center channel, to something a bit more modern, and hopefully better matched. There are times I'd like to kill the CC speaker, and I don't know if it's the old amp (Dolby PL/I with internal SW amp), declining broadcasting standards, or a mis-match between the Polk and the Advents. The wife will go for one speaker, so I'm using that opening to perhaps build 5.
I post this here because I have the same dilema - how to fit a CC into existing furniture. My first constraint is a 6" vertical height. This drives me to looking at 5" designs, a rare thing on this forum!
The second constraint is personal - I want a matched set of non-identical speakers. Thus I've been looking for designs that:
- use the same tweeter in the mains as in the CC/surrounds
- use similar woofers
- have optimized crossovers that yield similar-quality frequency response
The third constraint is practical; I want to start small, with a CC that I can hide in an entertainment center, move on to surrounds I can hide in the corner before trying for furniture-grade mains. I focus on appearance here because I have no doubt I can build a functional enclosure that, with quality drivers and a proper crossover, will sound good.
I've read through the Mission Accomplished files and find many good reports using Dayton RS-series drivers. The RS28A tweeter is very popular, and I've found it used with a range of RS-series woofer in a variety of designs. Based on this review, here's what I'm thinking.
Mains: Natalie P tower
Natalie P initially caught my eye, partly due to an appreciation for Leon the Professional, part due to a personal preference for 2-way designs. Based on the number of variants, it's a mature, low-risk design that will likely push the limits of wife-acceptance-factor.
Surrounds: Microlith/ported
I only find one design using the RS28A with an RS125. It's a 7.1" tall enclosure, so it fails the CC height constraint, but it's a starting point. The risk is that it's not fully optimized. The designer, Javier Huerta, notes some minor XO issues toward the end, and I've asked if he ever finished a promised XO design update, but the thread's been dormant the last 2 months.
Center: Microlith/sealed
Javier specs a 45x18x26 cm enclosure using 3/4" MDF. If I trim an inch off the height, while maintaining internal volume, the dimensions come out to 45x15.25x28.6 cm, including two other changes:
- 1/2" MDF for top and bottom (saves 1/2" height)
- add a center brace like the PE boxes used for Natalie P. to compensate
This brings me back to the start - I am modifying a design to fit a need. Given the overall plan, what do I need to know now to get started? Is this wrong-headed, or am I missing something obvious?
Thanks,
Frank
