Erik, I am not the type of person to engage in "subtlety of language" If I find fault or (even some faults) with a speaker system I own or have owned that does not necessarily mean I am dissatisfied. I just may keep the GET 7's and be done with it especially should I find the "right" pre-amp for the BAT amp. I just purchased.
The amp has made a difference in the sound. If I had to cite a percentage, 20-25% improvement in the sound would not be an exaggeration. Therefore, the issue of a new speaker will not be even considered until the pre-amp spot is filled in, then I will either proceed choosing a new speaker or just rest my case with the model 7's
BTW, a friend from long ago had a pair of speakers built for him which he claimed used all JBL drivers. The year was around 1974. Personally, I thought their sound quality was below average, if not just terrible. At the time I owned a pair of ESS 7's (not the Heil Air Motion version.) Just a Philips tweeter, midrange, and a KEF B139 oval driver. which provided excellent deep bass even by the standards of the day. I don't know how anyone can DIY a speakers without testing it in anechoic chamber to measure distortion and frequency response
Since my long response of August 25, and after reading several of member replies, I did a little homework based on those replies. Upgrading to the GET 5's at $1995. really does not offer that much improvement in sound even if the local dealer offered me an upgrade trade-in of the model 7's The GET model 3 at $2200 offers maybe more clout in the bass, but its design goal appears to be more for home theater.
Someone mentioned the Tannoy XT-8F's separately reviewed by Neil Gader and Robert Hartley of TAS. They highly praised the speaker, but had some criticism about an overripe bass that could be somewhat corrected using either a pair of rolled up socks in the port of each speaker to control the bass, or getting some plugs from Tannoy. I loathe having to use plugs because it is somewhat of an admission of an unfinished design.
Nevertheless, the Tannoy XT-8F speaker deserves an audition, if I can find a dealer within 30 miles of home
So there it is;:..... thanks for the comment, I really do not feel I am on a speaker merry go round. Sometimes the search for sonic nirvana can be fun.
