Spica TC 50 Question s

I recently re-invigorated my audio interests, big time. I'm using an Adcom 535 II amp, Parasound PHP 850 pre amp, and Spica TC 50's. The system sounds great (cd player is a Cambridge CD4 SE) and my research tells me I really don't need to upgrade the speakers, which I purchased 13 years ago and are in perfect condition. I find the bass response is lacking while the imaging is great. I'd like more punch in the sound at lower volume levels.

Any suggestions as to how I can acheive this ? Subwoofer (I've seen the Velodyne mentioned) ? Better speaker wire (I'm using basic 14 year old monster cable at present). Anything else ?Thanks for any help that can be offered.
A more powerful amp would be helpful and of course, a subwoofer. Spicas are not the most dynamic and can be damaged by overdriving so be careful. The Adcom and Parasound may also not be the most dynamic pieces. As regards subwoofers, the Velodynes may not be the best match, either. Look into REL which will mate with your amp and may sound the most like the Spicas. However, it may be best to run the REL like a regular sub, that is, cut the Spicas off at around 55-60 HZ. This should help give the Spicas some "breathing room" for dynamics.
REL Storm is a good choice for the Spicas. However, a while back I used two Mirage/Energy 8' subs with great results. These subs were relatively cheap at 500.00 per the pair retail.

A good tube amp (Conrad Johnson, ARC) would improve the sound of the Spicas, but not necessarily the bass response.
Hi Fredman ... different thread, but I can also respond to this one. I own spica angelus and I had the same problem ... wonderful midrange and imaging (thrashed Spendor s3/5 in imaging) but not enough "drive" to get my toes tapping.

I added a REL Strata3 and now the system sounds absolutely great. The downside was that, even used, it cost $800. Add the $800 to the $250 you'd get for the tc-50s and you'd have over $1000 to throw at new (or used) main speakers. It's a real trade-off, since $1000 buys some good speakers. I have seen kef reference 103.4 and Epos es-25s for less than $1000 used, both of which would probably beat the tc-50 + sub combination, IMHO.

So in summary a REL strata 3 will definitely give you the bass and drive you want, but unfortunately at quite a high cost relative to the rest of your system. On the other hand reselling the REL is extremely easy, so it won't really cost you $800 if you sell it in the future.
