Harbeth Super HL 5 Plus room size?


Would this Harbeth be too big for my 20x15x8 listening room. I sit about 7 feet from my current Harbeth P3 ESR with JL Audio subwoofer. There is a pair listed here at a good price. I love the sound of the P3 in my room and was wondering if the larger ported Harbeth would be the right move to make? Are there any HL5 owners out there? BTW, a few years ago I tried the Compact 7 and I preferred the smaller P3!

I have Harbeth SHL 5+ 40th anniversary in 18x12x8 room. 36inches from rear wall. 8 feet apart. My chair is about 9 feet from the front speaker plane. Sounds great. I also have a pair of the P3esr 40th that I one afternoon put in the system using the same footprint. Amazing how good they sounded; not the full sound of the SHL 5, but good nonetheless. If you can I recommend the 5s.

You should be fine.  Harbeths actually seem to do pretty well in "normal size rooms," especially as they probably originally targetted British homes (I believe Alan Shaw has said so).

In any case, my Harbeth SuperHL5plus worked fine in my 13' x 15' room, in terms of even frequency balance, no bloat etc.

My only issue was a somewhat limited soundstage depth.  Quite a number of other speakers produced more believable depth and dimensionality in my room (including my current Thiel speakers).

The Harbeth speakers didn't seem to have this noticeable problem in the stores, but then the store auditions I had were in a large demo room.  So either they bloom in soundstage in a larger room, or perhaps it was because I was sitting further from them at the store and so due to that the soundstage seemed deeper.
FWIW....

Check out this guy for 40.2's in a small room.  Scroll down (and down and down) for photos of room and acoustic treatment of walls.

20x15x8 no problem. As a matter of fact the room may be a bit large for the Super HL5 Plus. I have mine in a 10.5x22x8 room.
