  1. Yes; a person with the skills would find it relatively easy.
  2. Something like this is the least expensive way to go between the woofers and the satellites: https://www.parts-express.com/subwoofer-crossover-8-ohm-150-hz-200w--260-220 some of the component values may need adjusting for your specific drivers, and you may need an L pad on the woofer or satellite side. Note that it can be split in two. EDIT (add): to calculate crossover values see: https://www.diyaudioandvideo.com/Calculator/SpeakerCrossover/ and another: http://www.apicsllc.com/apics/Misc/filter2.html
  3. Hi Jerry; I have a couple of NHT Super Zero 2.1 speakers - they are great little speakers. I originally purchased them with the intent to do something like you described, using AR91 speakers for the bottom end with an external Parts Express 2 way passive crossover. One of my 91s was in need of a midrange driver; which I was able to pickup and install before the project got going. Simply Speakers has replacement AR 12" drivers (and dome mids and dome tweeters); AR 9, 90, 91/92(AR58S?) crossover drawings are on this site - just have build them. For less than $1500- in materials, with some wood working and soldering skills, it is possible to build brand new replicas of a pair of AR91 or AR58S speakers; a pair of AR9 speakers for less than $1000- additional in materials. Labor in the USA (if you paid someone to do the work); would be much more than the materials.
  4. I am planning a similar unit, using an 91/92 crossover, which I have. I also have the UMR and a couple of 8" AR woofers. I am debating about the tweeter. These are the three I am thinking about: https://www.parts-express.com/hivi-q1r-1-1-8-textile-dome-tweeter--297-417?utm_source=google&utm_medium=cpc&utm_campaign=pla#lblReviews https://www.ebay.com/itm/AR-Acoustic-Research-Replacement-Tweeter-for-AR9-AR11-AR58s-Speaker-MT-4121-4/152720220413?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20131017132637%26meid%3D93a23f89998f4c9bb085e0174b82c2b4%26pid%3D100033%26rk%3D1%26rkt%3D7%26sd%3D152720220413%26itm%3D152720220413&_trksid=p2045573.c100033.m2042 https://www.simplyspeakers.com/acoustic-research-replacement-tweeter-12000840.html?gclid=CjwKCAjwnLjVBRAdEiwAKSGPI6HjJT-EQcJOj4-pWsN04I3yoL6HQz9UJFub8xKq8ZbZrRfE1_kLRhoCcqsQAvD_BwE and of coarse I am keeping watch for a good deal on 91, 91.5, 92 and 58S speakers.
  5. When I had AR9 speakers set up a decade or so ago, I used the amplifier sections of two Onkyo TX8500 recievers (dual independent power supplies) in vertical bi-amp mode. They worked great. Unfortunately, I had to sell that pair of speakers. I am finally getting around to rebuilding my 2nd set of AR9s; the upper section is ready, a professionally is refoaming the woofers, hopefully I'll get them back on Saturday. I am concerned that the TX8500's may need some refurbishing, I got estimates in the $500-$600 each range from a couple of places here in the Bay Area. I am not ready to pull the trigger on that, and am considering purchasing a digital oscilloscope instead, and doing it myself. Of course, I don't have the time..... So I purchase a Crown XLS1502 amp for now.
  6. Hi; I am looking for information the Boston Acoustics T930 Series II speakers, any suggestion on sources? We picked up a pair this afternoon. Thank you Nigel
