Go for the Samson Resolv 65a
I upgraded a small project studio a couple of weeks ago and ran into space limitations that made me look at active monitors with 5" woofers.
After checking out the market, IMHO, there are NO monitors out there that can adequately represent bass frequencies with any presence or accuracy so long as they rely only on 5" woofers.
Without going to a subwoofer configuration, you need at least an 8" woofer for a substantial bottom end. For this, expect to pay upwards of $400 - $500 for an decent active monitor pair.
I did not have the cash, not the space for these larger monitors. I did not want a passive monitor+amp setup. I don't like subwoofers for monitoring. So I wound up looking at a number of 6.5" woofer equipped active monitors.
I bought a set of
the Samson Resolv 65a monitors:
1. They are compact and built solid.
2. They have multiple connections, including TRS and 1/4".
3. They are front ported, which allows for more apparent bass and placement against a rear wall.
4. They have a mid-range frequency adjustment switch that allows you to tailor the sound to room characteristics or to mimic different speakers.
5. Although I cannot measure this scientifically, to my ears these monitors sound flat and uncolored. There are no unusual characteristics that would require long hours of ear training and compensation.
6. They are a bargain at the $299 you can pick them up for at any online dealer. Refurbished/returns/B-stock they are often available online for $255 - $275. I bought mine on Ebay for $225 + shipping.
Are the Samsons adequate for deep synth bass licks, pipe organ, sampled bass drum hits, tympani or string bass? No. You can't overcome the limitations of physics. Are they a great compromise taking into consideration size, price and audio performance. Absolutely.
If you have more money available, check out the Haflers. They are the best in their price range. When your music is covered by 50cent and the sky's the limit, go Dynaudio. In the meantime, the Samsons will more than do ya.
