Boston Acoustics hd7 Review- A Complete Guide

In the audio industry, Boston Acoustics is a well-known brand. You may have noticed their car audio systems in some vehicles if you haven’t seen their speaker goods in your favorite electronics store. As a result, the brand needs little introduction.

On the other hand, you might not have heard of their most recent speaker, HD. The HD is the company’s attempt to deliver its unique sound in an appealing package with long-term value. The HD9s confirm my general perception of Boston merchandise, which is that I enjoy it.

I presently own HD7s, and this is my second HD series talk. In the cheap bookshelf speaker series, I believe the HD7 is a strong performer. You can buy them for $20 and then reform them for another $20. It sounds really clean and precise to me, but it’s a little light on the bass. Acoustic suspension appeals to those who don’t like the woofy sound. The HD7s are excellent for bedroom use.

The HD9s are fantastic. The high end sounded wonderful to me, and I believe it has a larger tweeter than the HD5 and 7. A 6.5-inch woofer and an 8-inch passive radiator are used. My wife and I both enjoy the music, and she mentioned the huge soundstage, remarking that there appeared to be a lot of space between the instruments. It received high praise from my wife, who is not a stereo nerd. I thought they sounded fantastic and listened to them for an extended period. It was a lot of fun. They were powered by Dynaco MKIII monoblocks and served as a stand-in for my Snell III.

At 21 inches tall, the HD9s are too big to be bookshelf speakers and too little to be floor standers. They’re a weird size in the middle, and they’re going to be workshop speakers for my Hafler DH200. These will replace my Pioneer BS22LRs. I’d use these as “in-house” speakers; they’re rather excellent. Even better would be HD10s. The larger one-inch tweeter (over the 7s and 5s) also appears to be a significant improvement. I’d replace my HD7s with HD8s if I could locate them with a larger tweeter.

I also possess a pair of Celestion 300 Transmission line speakers, so I’m curious about other ways to improve the performance of a smaller woofer. I have to say; the passive radiator appeals to me. It’s not as clumsy as a port, has more length than a sealed pipe and is far less complicated than a transmission line.

I believe that Boston Acoustics from this and previous eras are undervalued because of visual “issues,” such as the vinyl veneer, which looks okay on vinyl but would look better in genuine wood. The spring clips used to connect the wires are one of the major perception issues. In the initial evaluation of speakers, audiophiles look for binding posts as a shorthand for quality.

Surprisingly, the guy who sold me the HD9s had just reformed them and done a fantastic job. I received a wonderful deal for $40. Surprisingly, I was just offered another set of HD9s for free this morning. I’ll probably pick them up, re-foam them, and give them to someone who will appreciate them as a lucky charm. There was no link between these two HD9 findings, but a set of HD9s with some beautiful stands came on Facebook Marketplace for $100. A bizarre antique speaker suddenly avalanches.

Pros
  • It has a high frequency response
  • They are sound wonderful
Cons

Conclusion

To conclude, the HD-7 speakers are quite comparable to the HD-10s, except for the passive radiator size. The HD lineup wasn’t the best when it was released, but it’s still a good set of speakers. You could do a lot worse for less than $100 a pair. The HD-10 was at the top of the HD range, with an MSRP of $440 per pair.

The metal domed VR tweeter is used in most current Boston Acoustics speakers, but these use the older soft-dome design, which is much mellower and less extended in the treble. The bass is a tad mild, so you’ll probably need a subwoofer, like with most bookshelves. The HDs have a distinctive sound that I haven’t heard from many other speakers. It’s a little “punchy.” If they’re within your budget, you should give them a shot.
