Sounds like you're trying to do a LOT here. Have you considered selling the L+R to a nearby bar or restaurant and then starting over with the resultant funds?
I'm working on a limited budget.
Double ouch. Have you had a chance to listen to them yet? Do they in fact need the addition of a tweeter? Do you have any EQ adjustments for the higher octaves? You'd most likely be opening up a can of worms trying to re-engineer these.
I'd like to add a single tweeter between the two Bose speakers.
If you're really set on adding a tweeter I'd suggest buying two shielded tweets with a mostly high frequency response (higher freq roll-off on the low end) and start out by placing them right on top of your existing cabs (face up in the long-standing tradition of Bose's direct/reflecting doctrine
). Adjust them with an L-pad. Plus make sure your amp can handle the impedance (can be matched with an appropriate L-pad). If you like them then start work on a crossover (if desired). If you REALLY like them, then just velcro/glue the tweets to the top of the existing cabs!
I've got the skills and tools to build a new speaker box.
Sorry to be so negative but without some modicum of Design knowledge IMHO you'd be better off using an established build (lots found around these parts), or buying a DIY kit as has been suggested. Otherwise you might just end up ruining these already "great sounding" speakers!
I'm also considering the AD18 from SMSL.
Interesting unit. I'd get more info on the exact output spec to be sure if it has what you need.
My current struggle is to understand if the SMSL amp will work as a pre-amp to the Dayton sub amp.
Sounds like your PC already has an LFE out?
Not sure which particular amp you're looking at but many plate amps do have high-level (speaker level) inputs. Some have built-in speaker level crossovers and outputs (to your L+R) too.
I'd like to have an amp/ or pre-amp that works like a PC setup. Meaning, I'd like the volume control on my desktop with a headphone jack that mutes the speakers when plugged in.
My motherboard has 7.1 capability. Again, I'd like to be able to control all the speaker and sub via a wired rheostat style remote.
Don't know if I'm understanding you right but couldn't you use the front (L+R) outs to feed the SMSL, and the LFE out to feed the sub? They are line-level right? Then you could control everything from your PC desktop.
The idea is to have a semi-compact, yet dedicated PC setup... I'm interested in a specific unit that fits my PC needs and is easily portable.
Don't know what sub you have in mind, but there are a lot of 1/2 ft^3 builds (mainly auto) that might suit your purposes. And a LOT of pre-made boxes too.
Well, best of luck with your venture. Sorry I can't answer all of your questions. Maybe someone can step in with more ideas.
