Subwoofer advice

@furiouslyadrift is very right about the Rythmik subs. Their plate amps have far more controls for achieving integration with main speaker than do most others. Not just the adjustable crossover (frequency and slope), but continuously-variable phase (not the insufficient 0/180 degree toggle switch found on many), damping (high / low / medium, at 14 / 20 / 28Hz), both line (from pre-amp) and high-level (from power amp) inputs, and 1-band PEQ.

Def 2 subs.  Everyone says this.  Can't go wrong with Rythmik or Power Sound Audio (PSA)  or SVS.  Folks who own the sealed SVS SB-2000s 12" give them lots of praise.  They are $1300 for 2, five year warranty.  The Rythmik F12 is a 12" sealed servo-controlled sub (the boss has a Ph.D. in EE), in a larger enclosure, and digs deeper.  More expensive, but, yeah, digs deeper.  About $1800 for a pair.  PSA is more of a home theater sub maker, but they do make sealed subs.  SVS has the best trade up policy, but they all have their own.  Bottom line, you can't go wrong with any of the 3 companies, but get 2 subs.

D2girls, you purchased a speaker that has limited bass, which will not really do that kind of music well, and due to its light weight cabinet it tends to be more warm and melodic then tight and punchy in the bass, which also makes intergration with a subwoofer more difficult. 

Harbeths are very musical midrange oriented loudspeakers like we have said in many a post. Shadorne is correct. 

Also a 10 by 14 room is really too small to really get two subwoofers in.

However, the correct way would be using two small very fast subwoofers, to provide a more even wave launch into the room and smooth out nulls, SVS woofers are a bit too boomy, and the Rethmik subs I dont think can derive their signal from an amplifer. 

Two Rel subs should do the trick. Put some Isoacoustics isolation footers under the Harbeths. Try to find a Rel dealer and borrow two of their smaller subs. You do not need a lot of output your room is tiny. 

If you try to roll off the bass to the Harbeths and put an electronic crossover in line with the speaker you may lose much of the musicality that you love out of the Harbeths. 

If you just augment the bass you may find that the extra output from the subs coupled with the Harbeths will just add that little extra you are looking for.

Thanks all for the help, I am looking to get a full range speaker to replace the harbeths with. Seems like the better, simpler solution than trying to round it out with subs. Honestly, I didn’t even want to change anything, its my significant other who seems really keen on it.

I was seduced by Harbeth marketing! I shoulda gotten something different, something better. Shoulda Woulda Coulda. You guys know I haven’t even been in this hobby for longer than a year right? Plus I’m 1/3 of your guys age. I’ve got plenty of time to learn more. Let this be a lesson learned... at least I didn't blow $30k on a single component like some of you guys... also I'll be able to sell the Harbeths for pretty much 90% what I bought em for. Got lucky there, I guess.

And all this said and I haven’t even really said anything about how I like how my Harbeths sound. I love them to bits. Obviously when you read a thread like this it seems I’m not 100% pleased with the bass output in my system. But I’m mostly pleased. As I said before, I'm not the only person who has a say in my system. It’s as simple as that. If it were up to me I’d stick with things as is, maybe add a sub.

And yeah I guess thanks Audiotroy for your suggestions and pointing out that I bought a speaker that doesn’t do bass. I actually knew that buying them. Blame the boyfriend for putting thoughts of upgrading into my head...

This thread has served its purpose. See: the new thread I’ve made, titled Deadalus Audio speakers Muse or Muse studio?
