![]() ![]() I would reach out to Odin with Earmark Marine with the same question. Like Focal's upper end models, the JLs passive crossover gives you tweeter attenuation plus selectable midrange crossover lowpass slopes to compensate for various car to car mounting positions. The upper end JL Audio components sound a little laid back in a soundboard but are voiced for a car and come alive. Both the upper end Focal and Hertz get really smooth and accurate. So naturally, I am a fan of a low resonance, well damped soft domes like the B.A. But it destroys the music integrity, and instead of Linda and James, you hear something strident. They typically use that cheap trick of accentuated highs to make the speaker sound more distinctive. There are a ton of marine and automotive speakers, where you can not distinguish who the background vocals are. For example, in the Neil Young song, 'Heart of Gold', Linda Ronstadt and James Taylor sing back up vocals. So to answer your question.I place a great amount of emphasis on midrange and vocals.because I came out of the classic rock era which is all about midrange. Today, it is nearly impossible to find a mobile electronics company with domestic engineering. Yes, it is a shame because B.A actually had some very good audio engineers on staff. And that why I know Boston stopped making their car audio stuff. Loved the pro 60s, but the SPZs were terrible and twice as much.ĭavid, what speakers would you say are the closest to duplicating Boston's sound? In a 6 1/2 round component speaker….I have a new project coming up. I always put Bostons pro 60's in everything, from the car to the boat. Both amps are super clean and it is hard to find any amp under several thousand that can generate 500 WPC RMS like the 500 can, heck even 350 WPC RMS like the 700 can. SHowing my age, still have the Phase Linear 500 and 700 series II amps (the AR's are bi-amped), Phase Linear pre amp and tuner, AR-9 speakers (just had them reconed)….and it was sad when Carver left and then Phase was sold to Pioneer I think…after that they made nothing but junk. I hope they claim some of the old greatness. IMO, the new company is still trying to decide what to do with Boston Acoustics. And, they sold off all their domestic tooling and production facilities. They let go of the engineering talent, and they had some great ones. They had no passion for mobile electronics so they discontinued car audio. Several years back, Boston Acoustics was purchased by an umbrella company that also owns Denon and Marantz. Most of the original innovators are dead now and the logos are no more than a marketing tool for some asian importer that bought the rights. It's the traditional NE speaker evolution of AR, KLH, Advent, EPI, Genesis, to name a few. I also have some Boston Acoustics home audio speakers, both old a new, among others. If you had more amplifiers of more channels running at higher impedance loads, you could actually be pulling less amperage than fewer amplifiers/channels of the identical power. So three amplifiers running a total of 2000 watts essentially pulls the same as two amplifiers running a total of 2000 watts. It's not the number of amplifiers, it's the COLLECTIVE wattage, topology (Class D, H, AB) and load (impedance does impact efficiency) that will determine the draw. There is only a couple (perhaps 2 or 3) of amps difference in current draw when you add another amplifier. Will I need to add a second blue top if I add another 1000 watts of power? Essentially a double from where I am at now. Currently I have a Blue Top for my stereo, and a regular cranking battery for everything else. ![]() Another one of my concerns with adding a third amp, is the additional draw on my electrical system. Ok, as much I don't want to have to redo and re-locate all my wiring and amp rack, I think I will probably stick with my two 4 channels and buy a big mono sub amp. I would prefer to use JL, Alpine PDX, Wetsounds or Exile, but can't spend that much. I am considering the Soundstream Ref5.1000 and the PPI 900.5. If I could find a reasonable 5 channel amp that will push 450-500 watts 4 ohms on the mono channel, I would consider it, but I haven't found one yet. I essentially need 9 or 10 channels of power because I am running 8- 2.7 ohm Polk MM cabin and tower speakers, each needing there own channel, and I can't run any of them in parallel, nor do I want to run them in series ( for obvious reasons) to help eliminate channels. Ideally, I would like to run two 5 channel amps for my system and am wondering what the downside would be if I used the mono channel from each identical amp to power one of the 2 ohm VC's for the sub, assuming I can closely match the output signal. I have a DB Drive 12" sub with dual 2 ohm voice coils thats needs a lot of power (700-1000 watts). ![]()
