Subwoofer advice

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?

Dave and Troy (audiotroy) just posted "the Rythmik (correct spelling ;-) subs I don't think can derive their signal from an amplifier." Look two posts above theirs, where I said Rythmiks do exactly that. The A370 (in the F12 sub) and H600 (in the F15HP and other models) plate amps have hookups for BOTH line level (from say a pre-amp) and high level (from a power amp) sources---your choice which to use. Dave and Troy---got it now? ;-)

@d2girls Congrats on the 30.2s. I just upgraded from 30.1s recently to the .2s and love them. I had the same issues with Harbeth as you are having re bass.  My solution was as several have suggested here - adding sub(s). I started with one HSU VTF-1 MK2, then added a second. Each add was an improvement. I then upgraded to dual HSUs ULS-15 mk2s as the smaller sub was not adequate from my larger listening space. To my ears and taste the ULS-15/m30.2 combination equals virtually anything I have heard in a showroom (except the $175K Naim/Focal system at my local dealer's open-house last week.)

I then added an external HSU High-End Crossover unit. Despite what is IMHO a miserable build quality, the external crossover adds a bit of magic to the bass while allowing the Harbeth to shine where it does best - in mids an highs.

I do have a question about inserting an external crossover unit into a high end system which I will post in this thread. But in all, subs do the trick with the m.30.2s

Actually I sold the Harbeths.. sorry 😅

@audiotroy  As posted above, I also have Harbeth m30.2s. 

I solved the Harbeth bass issue by adding dual HSU ULS15 mk-2s. (My listening room is (a) 12 x 14 for near field, which opens to (b) 20 x 30 which is why I upgraded the HSUs from VTF1 MK3s to the ULS 15s.

Also, having recently added the HSU High-End External Crossover I have a question:

I have been told that inserting a crossover between amp and pre will degrade the preamp output with noise, distortion, phase-shift, etc. when you go through the crossover electronics.  Also, that an external cross-over will also defeat any benefit of high-end after-market interconnects in the pre/x-over/amp path. 

Do you have any thoughts about this?
Thanks for any input.
